anti theft????

[jose16]

ok guys so im new at infiniti, but yesterday my q45 was fine untill i took off the old stock stereo becuse it didnt work and i put in another one, and now the car wont start does the 1993 q45 have some sort of anti theft system, if so how can i fix it?

[qsiguy]

The OEM anti-theft system isn't connected to the stereo so that shouldn't be your problem. What are your exact symptoms? Will it crank and not fire, no crank? What?

If the OEM system is armed/triggered you can disarm it with the OEM keyless transmitter or by unlocking the door with the key in the drivers or passenger door. I think the trunk will work as well.

[jose16]

nope no crank at all, whats the oem keyless , i only have the keys

[maxnix]

Post 1993 had keyless remotes.

My guess is you probably have an incorrect or missing connection under the dash. Just a guess. What else changed?

nothing i just unpluged the eltrick windows, and the defrost, but there back on, and it wont wont on for ****, it wont even crank

[goody90q45]

Did you disconnect the battery? Check the battery connections anyway for tightness or presence of corrosion. Either one can cause a no-crank condition. Good luck.

Silly question, but did you make sure the car was fully in "Park"?

I know to remove the HU I shift the car into Low 1 to allow for extra clearance.

Also could be the shift lock, try using the manual over-ride ont he right hand side of the shift/gear indicator.

[jose16]

nope the battery is fine, i did disconect the ground , to reset, but it didnt work,, oh and the car is fully park

[maxnix]

Well, you might have jostled a non-secure connecetion.

Time to check all of your fuses, including under the hood.

[jose16]

well all the fuses seem to be fine, so do any of you guys know if the 93 q45 has some kinf of reset?

[qsiguy]

Do you have power to everything else? Headlights, dashlights, radio, etc? When you turn the key to the crank position do you have any clicks or notice anything like interior lights dimming?

[jose16]

well all my lights go on my power seats work as well as m windows, and the stereo also works

[qsiguy]

Are you handy with a meter or test light, do you have one/all of these items? I could walk you through some things to try but you need to know what I'm talking about so you don't damage anything.

For instance, There is a starter relay under the hood you could do some tests at and even put a jumper across it and it should start unless you have a fuse out or something.

There was a thread a short time ago where I went into some detail about this subject. Let me go find it....brb

[qsiguy]

Here it is, found it. Much discussion about t-shooting crank issues with several wiring diagrams, etc.

[jose16]

your right im not thatt good , but yesterday me and my day tried starting it by jumping the wires from the battery to the starter isnt that hat ur telling me to do??

[qsiguy]

basically, but I wanted you to just jump the terminals at the starter relay so we would know if the power to the starter relay was good. If jumping the starter relay doesn't work you may have a fuse out (or one of several other things but this will help us start narrowing down the problem).

So did it crank when you jumped wires from the battery to the starter?

[jose16]

ok so i got a mechanic to run the computer, and it urns out the computer froze, so its gonna cost m 400$to get it fixed

[qsiguy]

Never heard of something like that? Sounds fishy to me. The computer doesn't have much to do with the car cranking. If you follow that thread I link to above you will find several ways to test the starter system by bypassing certain circuits. I would do some basic troubleshooting before shelling out $400 for a computer.

Second, what "computer" is he talking about? You can pick up an ECU for about $100 +/- and it takes about 15 minutes for a novice to install.

Last, many computer glitches can be reset by disconnecting the battery for a few minutes allowing the computer to reset. Have you disconnected the battery since it died?

The whole situation is odd since it died right after you pulled the radio. Sure seems like there is something simple that's going on.

[maxnix]

Improper jumping technique may have fried the ECU.

Best to repair the cause of insufficient charge/voltage/battery amps, not jump the car battery.

[jose16]

you think, i want to keep on checking b4 i do pay 400 to get it fix, would trying a different battery be any differen?

[qsiguy]

If you are unsure of the condition of your current battery and you have a known good one you can swap in certainly do that. If you can turn on your headlights without the interior lights dimming you will likely have enough power to at least click the starter or get it to crank slowly.

You never said whether it cranked or not when you jumped power from the battery to the starter. If it didn't crank by doing that (and you are sure you jumped power to the right terminal) then either you had no power in your battery or the starter/solenoid is bad.

[jose16]

OH, SO ITS NOT THE BATTERY, WELL, GUYS I DONT EVEN KNOW WHAT TO DO, DAM I GUESS ILL STICK WITH CHEVY OR DODGE

[qsiguy]

So it DID crank when you ran a wire from the battery to the starter? We really can help but you need to fill us in on what you are finding. We need info since we can't be there to help you personally.

Amazing how difficult it is to get a straight or relevant answer from someone seeking help, isn't it?

Simple Yes or No question.

[jose16]

the starter did make some noise like if it moved, but the car didnt go on

Yes it is at times. but....we're here to help and I'll keep diggin for some answers for now..

Jose,

That answer is still a little vague. The starter just making some "noise" is no indication that it's working. If it was in fact cranking you'd have seen the whole engine/fan/belts spinning while it was cranking when you had it jumped.

Do you hear the same "noise" you heard when jumping the starter when you try and start it with the ignition key?

For the car to "go on" when you jumped the starter you would have had to have the key in the ignition and have it in the RUN position. This is assuming the motor was actually cranking and not just making a noise.

Jose, That answer is still a little vague.

Ever feel like you were tunneling through Jello?

sounds like you broke it.NATS immobilizer didnt come out till 99
