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

[blackmagic]

ok before you tell me to search i have i searched the blinking red search button on this forum. i search on yahoo.com on google and cant find anyone with the same problem. ok so i finished my swap and had the car started and it sounded great besides the muffler with a hole out the back but thats besides the point. i took the car around the block mabe a 2min. drive and when i was pulling into my driveway the car turned off. i try to start it all its doing is cranking over. if i let it sit over night or for a few hours your can hear it trying to start i pulled the plugs out and they are wet with fuel. so i take the fuel pump fuse out and try to start it well it actually starts but when the fuel that was in the lines burns up the car stalls. so i put the fuse back in and try to start it and it almost runs for 1 sec. but then it stops and its just cranking i think its getting to much fuel. so i check the ecu for codes its throwing a 13-coolant temperature sensor. go to autozone pick up a 1991 nissan sentra 2.0 ser sensor and put it in the car and try to start it and its doing the same exact thing and still throwing the same code. it would make sense if it was the sensor because it would be telling the engine to give it more fuel and when it spits more fuel out before there is a complete burn it with put out the spark am i correct? exuse me for this long post but idk what to do next anyone have any ideas did i get the wronge sensor i looked it up on some thing on yahoo and it said to get that sensor for my motor but then on the nico thread they say the ka24de sensor would work for my sr20det. the car the motor is in is a 1995 zenki and the motor is a s13 redtop. thankz in advance. if you can figure this out i will you for life!

[blackmagic]

anyone... please... help....

What size injectors are you running?

[blackmagic]

stock everything on the motor is stock a buddy of mine said it could not be getting anough spark but if its not getting anough spark now y was it before? and now my battery is dead from trying to start it so much so now i need to recharge it and hope it doesnt die again cause then ill be buying another battery

[blackmagic]

by the way nice valve cover i just spraied mine but it came out alright im still going to get it bowder coated as soon as i get her running right

[blackmagic]

does anyone have any advise. i have been on vacation just got back and realy want this thing to run my daily driver is about to get some new paint and i need somthing to drive wile its drying

[duffman1278]

The valve cover on there is PS, lol but I to powder coat it that color. Anyways. Have you checked your coilpacks for resistance? its in the FSM, you just check resistance between 2 points on the coil packs. I would assume their good, but theirs a possibility that they might damaged. If that checks out fine, check the resistance on your ignitor, make sure its nothing too high, and check your wiring

[Hijacker]

Check your fuel pressure. I bet it's running high. If it is, you'll need to replace the pressure regulator. The pressure should be between 41-43psi

[blackmagic]

ill check both tomarrow ill get back to yall tomarrow somtime if i can get a chance.

[duffman1278]

Yes, do so

[tiger]

dont mean to thread-jack here... but I kinda had that prob this morning.. I recently installed a nismo FPR. This morning I guess the air/fuel ratio inside the cylinders was off and it wouldn't start.. I pulled my plugs let them dry and then removed the fuel pump fuse and burned up all the fuel then replaced and then it started.. thank god. I have no codes. I have a GTR fuel pump and a stock sr with fmic and 3'' exhaust. I wonder if I am having injector leakage or something.. do injectors leak sometimes? I smell no fuel during startup, so no o rings leaks I guess. I have never replaced the o rings on the injectors when I took them out. :/ I buoght a brand new fuel filter today and the old one looked oem .. pretty clogged up i think.

hey just wondering... did you clear the codes from the ecu yet? If so, check and make sure they don't come back.. there could be a short or somethjing in the wires around there.. who knows.

[duffman1278]

To tiger, YES! replace the o-rings! I didn't do it either when I pulled out my fuel rail, and didn't think much of it, well...I was wrong, the fuel was actually leaking through and causing 2 of my cyclinders to get too much fuel inside. So I replaced them last night and it solved the problem. So I suggest you go and replace all the o-rings on each injector. The top and bottom one, assuming you have side feed injectors

[blackmagic]

didnt get time to work on the car today i had a double shift at work someone called out but i have tomarrow off so ill try to check it out tomarrow. but yeh i did clear the ecu but the code keeps poping up so idk if theres a short in there why would it have started about 20 times before i tried to drive it. that was the first time i drove the car but before i drove it i could start it up no problem and it would run strong the only problem was there was white smoke and it smelled like a gasket was burning from the turbo but after awile it wouldnt smell anymore i wonder if it just had **** in it or somthing from sitting so long?

[duffman1278]

White smoke could mean burning of your coolant.

[blackmagic]

the oil has no coolant in it and the coolant has no oil in it and it stopped after awile it wasnt coming out of the exaust just the engine bay. i still havnt had time to stop by auto zone and get a fuel pressure gauge im hoping tonight when i go pick up some stock se wheels for $20 with tires hell yah

[tiger]

To tiger, YES! replace the o-rings! I didn't do it either when I pulled out my fuel rail, and didn't think much of it, well...I was wrong, the fuel was actually leaking through and causing 2 of my cyclinders to get too much fuel inside. So I replaced them last night and it solved the problem. So I suggest you go and replace all the o-rings on each injector. The top and bottom one, assuming you have side feed injectors

Thanks!!!! I do have the side feed, stock injectors. Hopefully it fixes my problem cause these injectors have been taken out and put back in more than a couple times so those o rings might be bad.. would there be an easier way to test? Like removing the fuel rail and turning the key ? I guess I should just replace them anyway.. my fuel pressure regulator is set to around 38psi with vac off.. so i'm kinda sure it's right. I guess that could explain my high rpm stuttering.. when fuel press is high more leakage causing bogging and hesitation? plugs are new btw. Thanks though i'll post up after i replace the rings.

alright guys this week has been hell with the christmas shopping working double time for christmas and alot of other things. i still havnt found time to check fuel pressure and i actually just bought the cyl. compression tester so ill be able to get all the compression #'s tomarrow. as for fuel pressure how am i to check that i know on some cars there is a little nipple type thing u put one end of the tester on and it tells u but i dont see any place for the tester to go on my fuel lines? if anything i just said makes sence? a buddy of mine said the regulator could not be whats causing it not to start he's a mechanic and says they disconnect the vacuum lines to regulators all the time but the car will still start. he said its probably not getting good spark how do i check that? and for the last question is my ignitor supposed to be bolted onto the body someplace to be grounded out i see it is on a buddy of mines but mine isnt.

[tiger]

you have to buy an in-line fuel pressure gauge. They're cheap, just go to autozone or something. I'm going to get one soon. As for that code.. it may keep throwing it because a wire going to the sensor may be shorted. Check to see what the wires condition is next to the plug. I do not think that would be causing your car to dump fuel at start up. I had a wire break off the CTS plug on my old KA and the car ran pretty rich while idling... enough to make your eyes burn when you're near the tail pipe. lol. Im also not sure what happens when a pressure regulator fails.. you might search on that one. There is another possibility that one or more of the fuel injectors are stuck wide open. I do not know how to check them with a voltmeter for proper operation but I know someone on this forum knows how. I only know how to check while the car is running. good luck, let us know what you find.

[duffman1278]

Ignitor doesn't have to be grounded, mines just hanging (for the mean time) and turns on. Check the gapping on your spark plugs than.

[tiger]

my ignitor is hanging also!

[blackmagic]

thats what i thought cause isnt there a black wire from the ignitor that gets grounded to the intake manifoild. well i checked my compression yesterday and i have 150 on #1 165#2 150#3 and 150#4 its weird i checked it 3 times but thats nothing to worry about i dont think. i got a multimeter yesterday night and im going to check to see how many volts are going to the coilpacks. my last resort will be tearing the nice wire tuck job apart and unlooming it to see if i wired anything wrong. but why would it have started everytime ever turn of the key but the first time i take it on the road it turns off...

[tiger]

dont forget to check those injectors too!

[blackmagic]

thats right i almost forgot ima have to pull the injectors and check if there are any leaking.

[blackmagic]

ok i just pulled my harness like 5 min ago and got into looking at wires i just came across a wire on the s13 ecu plug it is pin 18 and its the water temp sensor input wire well its not connected? is that supossed to be?im still pulling it apart hopfully i can figure out y the car isnt starting.

[blackmagic]

ok i take back the last post it is connected idk what i was looking at

[tiger]

how is it going? what are the injectors like?

[blackmagic]

havnt checked injectors yet but i think i may have figured it out i pulled the harness apart and was looking at the coolant temp sensor plug and found a wire not hooked up so i found where it was supposed to go and i soldered it on. now im going to tape it back up tomarrow and try to see if the car will start ill keep yall posted

[tiger]

hmm that will fix your error code and running too rich. let us know what happens,

[blackmagic]

ok well now its throwing 55 im gonna look it up right after i post this

[blackmagic]

ok wtf is going on i just looked and it says 55 means ok but y wont my car start???? ahhhhh im getting to the point that i sell the damn thing and start over but stay stock! somone help me
