J30 1997: Window shield, Injector fuse, Bose audio

[infinitij301997]

Hi,

I just got one second-hand Infiniti J30 1997 one month ago. The mileage is pretty low. But some questions emerged ever since:

1. The front window shield seems different from the rest glass windows. All of the glass windows have an original manufacture marks except the front window shield. I consulted with the previous and the first owner who told me that there's no replacement at all. What's the reason for the difference?

2. I found the fuse box under the hood has no injector fuse inserted in place. The car seems to be working properly. Is the injector fuse not necessarily required?

3. My Bose audio system has all power off from 2/12/2007, no radio, no cassette, no CD player, no LCD display. I tried to open the wooden trim on 2/24, but suddenly the audio back to operation. It's a relieve for me to have the music back to life. Sadly, the next day when I turned on the ignition, the audio was not back to power as I expected. The silence makes me concerned. Is the audio power malfunction related to the igition key or starter, or any other reason? I checked the two fuse boxes, one is under the hood but has no place for the audio fuse. the other is under the wheel with one audio fuse but no problem was found.

I'm a newbie in the car repair. Any timely response with details is greatly appreciated.

Thanks for your help.

as far as the audio goes. chances are theres either a loose wire or the radio is just shot.... mine had similar results to that. it would work at times, it seemed as if i hit i certian spot and it would come back on, then later go out. as far as the other two, i cant tell u much about until i look at my car and get back on the computer, which wont be for like 8 or 9 hours. chances are by then, u should get some useful answers from other members here.

mine is a 1995 J30t (i didnt change the fuse box setup what so ever when swapping my engine and transmission), i have an injector fuse in there, i just came back from checking it, it is there near the fuel pump fuse, i really dont know if the 97 has a different setup, but i hope this helps, good luck

[infinitij301997]

Hi,

Thanks for your responding to the possible missing of my injector fuse. There's one chart on the back of the fuse box that tells me the exact fuse location. That's the reason why I found the injector fuse is possibly missing.

My question is whether I should insert one spare fuse (with the same specification) into the position? or if I just let it be, will it affect the operation efficiency of the car? Is injector the same as the fuel injector? By the way, I found my car a bit slow in accelarating when I step on the gas, is it related to the missing of the injector fuse? How about your accerlator responds?

Thanks for your helpful info.

acceleration is not really related, and if the car works fine without it then dont put it (that is what i would do, but again i could be wrong).... but i know that if the engine is runing, then the injectors are working, so no need for that fuse IMO

i would rather leave the acceleration issue to someone with more experiance in this, i would only be guessing that the timing is probably off (it should be 15+-2 degrees BTDC), or a cylinder compression issue (highly doubt it though), or fuel delivery (again i dont think so because the engine would be hesitating upon acceleration, and eventually die), why am i blabing.......loool, leave it to the experts...

[NismoChi]

If the car is running just fine, you are not missing any fuel injectors fuse.Give it a full tune up with some quality parts and the acceleration should improve.It is a good car, you'll enjoy it

Welcome to NICO!!!

If your windshield doesn't have a "Nissan Motor Company etching on either the lower left or right side of the windshield its not the original. Its a replacement.

Hi,

More questions:

1. My radio had no power at all, no radio, CD, display, at all. I checked all of the fuses and found none was broken. It's rare to have loose wire from other guys' experience, but if I was really so unlucky, how to check the wires? Do you think it's necessary for me to pull the wooden trim to examine the head unit? It is no wonder a tough job and I'm not daring to give a try. I appreciate you tell me in details how to check the wire.

2. I usually pump gas when the light turned yellow, I can pump 16 gallons in the tank, but it's still much less than the full capacity of 19 gallons. Do you think it's regular for the light to turn on when the tank still has around 3 gallons' gas? Someone told me I can't wait until the light turns on to pump gas, because it's damaging the engine, is it true?

3. Should I input a fuse in the injector position under hood that's vacant now?

Thanks a lot in advance.

first off i have a 1994 infiniti j30t that was the proto type for the 1995. i have consulted with the infiniti mechanics over this issue and have came to a conclusion.injector- from 1995 to 1997 there was no major changes in the J30 or the J30T models. i was informed that the fuse is best to have in. without the fuse, you will EAT more gas and have lagg points in performance due to an incorrect registry in the CPU from no fuse. so PUT IT IN!windshield- NO NISSAN LOGO MEANS AFTERMARKET! check recites and car fax for car history.performance- things you should do with any car you get. put in the injector fuse, injector cleaner, run 91 octane, put a bottle of HEAT in your gas tank ( will get rid of water in your gas), check your MAS (mass airflow sensor) located on your intake at your filter box, put NEW transmission filter, fuel filter, air filter, tune-up, synthetic oil change and run one bottle of Lucas boost through your gas to revive your car. THATS ALWAYS CAR BASICSwire-pull out the head unit (trim and all) and look on the back of the head unit for any loose wires (meaning: keep car on so radio should play and move the wires around to see if you have a bad connection)

Hi,

Thanks a lot. I'll put in the injector fuse following your advice.

I usually pump gas when the light turns yellow, I can pump 16 gallons in the tank, but it's still much less than the full capacity of 19 gallons. Do you think it's regular for the fuel light to turn yellow when the tank still has around 3 gallons' gas? Is it related to the oil filter, or is it time for me to have the oil change?

Someone told me I can't wait until the light turns on to pump gas, because it's damaging the engine, is it true?

By the way, what is HEAT? where can I get it?

Thanks for your advice.

for best car life i would put gas in when u reach 1/4 to an 1/8 tank. running your car low on gas can cause burnt valves or worse.

there is always 3 gallons res. 16gallons to fill is common

HEAT is sold at most all autopart stores. it comes in a yellow bottle and is mostly by the injecter cleaners. HEAT is a product that raises fluid temps. in raising temps, it allows the motor to evaporate water in your fuel. (water in fuel= bad= bad gas millage / performance=hell) most gas stations delute their fuel to have more fuel and make more money (ampm, arco, thrifty, valaro, and some shell's) higher quality fuel= better performance and millage.(top 3= mobil, cheveron, 76's)

oil change an tun-up every 3000miles <--- when was your last? if over then CHANGE

and for tune-ups use only platnum 2 sparkplugs. <platnum 4 sparkplugs are a waist unless your drag racing with motor mods> <standard sparkplugs burn up to quick with our 280hp 4 cam motor>

hope that helpsKRIN

windshield.... I agree with the replies on that...I'd think if it's the original it would have the markings, but I cant verify since mine's been replaced.

Replace all the missing fuses...but most importantly...I'd be checking into why they were removed...

Gas...running low on gas will do absolutely nothing but cause your car to die if you run out completely.....running low on gas will do nothing to your valves, nor anything of the sort. Running low on oil however, will damage your engine. And if they changed the capacities between 93 and 97 then it should only hold 16.5 gal...if I put in 19, I'd be running over all over the ground. 15.5- 16 is the max I've ever put in, and that was with the needle resting on E.

And sparkplugs...get the OEM plugs...too many issues with any others. Trust me and everyone else that's a veteran to J30's the OEM Laser Plats work the best. Although I havent had any issues with the Iridium IX's as of yet.

and Heat, is a chemical that contains alcohol to "dry" water...it doesnt increase the temp of any fluids

also, the last time I checked the VG30DE in the J30's only puts out 210 hp...not 280...the VG30DE in the 300ZX only puts out 222 in N/A form....you only get 300 even in TT trim

[infinitij301997]

Sir,

Very impressive. Thanks a lot.

Again as to my broken original Bose stereo, I still don't know the exact reason why my stereo doesn't work at all now. I usually put one CD into the CD player that whenever I turn on the key the music is immediately surrounding me, but now it's all silent. No CD, no radio, nothing. I know the firtst step is checking the fuse but it seems ineffective. Do you have any suggestion as how to do in the second place?

Look forward to your helpful hints.

hello~I recently got a j30 myself, it's 97 as well. Well, it's a bit rare that the plug behind the radio loosens off by itself but it is still possible. Maybe the previous owner had after market stereo in there and swapped it back with original before selling it. The plugs are probably altered and new cables are ran to your speakers. I'd take out the radio and check it if I were you or a local car stereo shop would check that for you for around $20. Good luck~

280 huh?

[brandonjustice93J30]

I questioned the same thing wondering where that extra 70 HP came from in our VG30DE's since the N/A 300Z only had 222 and the TT 300Z had 300...

and if Intake and exhaust claim to achieve that much...then I'll strap on a fart cannon, a CAI and for extra measure I'll slap on a vtec sticker for an extra 50 on top of that 70 lmao....

...and I questioned the plug choice since 95% of the long term owners say anything except the OEM NGK Laser Plats dont run quite right.

[gr8scott72]

I believe the J30 is 210 hp and 193 tq.

Your BOSE doesn't work because it says BOSE on it and it's old.

Seriously, it's probably the radio itself and it will be just as cost effective to replace as it will be to fix.

I replaced 100% of it with aftermarket and probably didn't spend much more than it would cost to have had the BOSE hu fixed. I have HU, EQ, 4 aftermarket speaker, amp, and 10" powered Bazooka tube. Sounds much better than the BOSE ever did.

[krin2000]

used a 98 chevy 2500 grill and cut it and did the same for the bumper

[krin2000]

by the way, 280 was a typo

"I believe the J30 is 210 hp and 193 tq."

Mines 225 since I put on the Nico stickers
