sr20det wont start cant figure out whats going on..help!

[duffman1278]

Yea it has done that before to others, given the okay but its not. Did you check the injectors, possibly replace the o-rings. And you don't have wet spark plugs anymore right? Make sure your relays are fine, especially the ECCS. I heard someone say that they used a 15amp fuse for the fuel injector and it made the fuel pump much more reliable, haven't tried it myself but just a suggestion.

ok now im realy ****in pissed my damn dad thinks he knows everything about cars and wont shut up so im workin on the 240 wile my dad is outside talking and talking away saying your problem is this and that and im like shut the hell up well i was putting the coolant temp sensor in and my dad pissed me off so much i wasnt paying attention anymore and i busted off the damn plug connection!! my question is i have looked and found 2 answers and wanna know which one is correct... i have a coolant temp sensor from a 91 sr20de and a 95 ka24de temp sensor which one will work and y are the posts that go into the coolant diffrent sizes from the sr20det? im not having a good day anymore.

[blackmagic]

o and i forgot to ask how do u check the injectors i searched it but didnt understand the hole checking ohms on the prongs thing what prongs do i need to pull the hole fuel rail or what

[duffman1278]

If you can give me the part number for the SR20DET sensor I could probably find out for which US car it goes to

[blackmagic]

im trying to find the part # but for some reason i cant and when i look up the coolant temp sensor on ebay or anything else it shows a blue plug but the one on mine is yellow???

[blackmagic]

what part of the temp sensor has the part # on it cause i see 1904 but i also see a27000008

[tiger]

did you look in the SR20det parts guide yet? My CTS has a red plug, looks exactly like the one on the KA...

[blackmagic]

the one on my 95 ka was blue the one i got from a 91 sentra ser was red but has nothing that lines up with the plug it connects to. if you know what i mean. o and im not talking about the plug that doesnt have the prongs im talking about the plug that is the coolant temp sensor with the prongs.

[duffman1278]

Apparently the Z32 VG30DTT coolant temperature switch works for the SR redtop, but the part number is 22630-51E00

[blackmagic]

ahhh now i hear that the 300zx works but i had also heard that the s14 ka is the same as the 300zx is this right anyone know for sure

[blackmagic]

alright guys i just checked for my self to see if im getting spark and i am. i tried to figure out how to check my injectors but i just cant get it. do i need to pull the hole fuel rail off with the injectors? o and i just took my multimeter to all the plugs and some of them arnt getting 12 volts wile the key is on the on position some are getting like 2.2 and 4.9 for an example is that right. i cant check them wile im trying to start the car but i have a feeling they only realy put out full power wile the car is trying to start.

[duffman1278]

ahhh now i hear that the 300zx works but i had also heard that the s14 ka is the same as the 300zx is this right anyone know for sure

Well I checked it on Nissan FAST so the 300ZX should work

As for your issue, try starting it with the MAF unplugged and check your TPS to meet the FSM spec. Also, clean out the IACV and don't tigthten the idle screw all the way in.

[blackmagic]

just checked my injectors and 1 injector isnt putting any fuel out next im going to check to see if there is any power going to it. o and its the first injector.

[blackmagic]

ok so the injector is bad now i need to get bigger injectors anyways cause i was gonna do it anyways unless somone has some injectors layin around they wanna get rid of for cheap

[duffman1278]

you can get an injector from an SR for like 25$ a piece

[blackmagic]

alright well i went on the classifieds and found 2 diffrent people selling injectors but they havnt said anything back if you know somone selling some send them my way

[duffman1278]

check on zilvia, post it in the WTB, I got several users from there about injectors.

[blackmagic]

hey duffman thankz man for that suggestion. i just bought 4 stock injectors for 80$ shipped. cant wait to put them in and see if this damn car will start

[duffman1278]

yea I just bought new ones too from deatchwerks.

[blackmagic]

what size i want bigger ones but dont want to go to big im not looking to get crazy hp.

[duffman1278]

370 What sucks is they had a sale on 550's last week on zilvia. It was the same price for the 550's as the 370's and I just found out today ftl. I'll be going with 550's though later, might be soon though if I find out that my ECU is tuned for it.

[blackmagic]

true true i was lookin into the nismo ones but idk a little pricey for me i think. what are you burning out your injectors or somthin. if your ecu is tuned for bigger injectors but u have smaller ones wont your injectors over load and burn out?

[duffman1278]

I dunno lol. Well when I opened up my ECU it has a chip in there and it reads "550CC" and apparently its tuned by some shop called TEPS in Japan, from what I've come to find out. But any how, I keep leaking from an injector. I went from 2 cyclinders, back to 2 cyclinder, now I'm down to 1 cyclinder thats leaking. So apparently not. I'm guessing the injector is stuck.

[blackmagic]

thats funny my buddy lee has an ecu that is tuned by some company and all it says on the ecu is boost up? it seems to pull harder than most sr's around here so idkif i was you id go with some 550's anyways.

[blackmagic]

ok well i just put the injectors in and charged the car batery again and tried starting it and it was trying to fire without holding the key in but if i took my foot off the pedal it would stall out it wasnt reving at even 100 rpm it was the same speed the pistons go when u turn the key. well i came home today and tried starting it again and it only tried to fire if i held the key as soon as i let go it would shut off. what the hell is going on could it be my timing? i have a timing light but how am i supposed to check timing if the car isnt running???

[duffman1278]

Are you sure your timing is on? If you don't have the 2 blackish looking links, look at these 2 circle indents on the cam itself. Make sure their at around 11 and 2 when at the second mark from the left. and reinsert the CAS. Believe me man, I took mine out at least 5 times. I even made a full circle on my CAS gear itself

[blackmagic]

is there any way for it to jump off timing by itself? could my coolant temp sensor wire not installed cause it to jump off timing? ill go pull my valve cover off tomarrow afternoon right now im working on my integra

[duffman1278]

I've heard that it could jump timing, I think it had to do something with the chain tensioner. Not too sure

[blackmagic]

having a bad alternator wouldnt reduce the amount of spark your gettingwould it? cause i remember with my old s10 the alt. went out but the truck still drove until the battery died the alt. is just to recarch the battery contuisly right? im checking timing right now have the cover off and going to look.

[blackmagic]

ok so i dont understand how to figure out the timing theres like painted circles on the cams and the gears and then theres the timing dots on the crank pulley how do i figure this out i dont see any diffrent color links on the chain or indents on the cam?
