I REALLY REALLY NEED HELP!!! CAR WONT RUN!!!

[hoosier240sx]

Alright so you guys know that sensor that goes into the radiator lower hose? It has a plug and all that ishh, is that necessary or no?

[compactfean]

Its makes your ac fan kick on when using ac and reaches a certain temp. If you are running ac you need it. If not than it is great to use as a temp switch to run electric fans...either way. Keep it.

[allenms240]

Isn't it the temperature readout sensor for the main temp gauge in the cluster, or for the AC as you describer?

[compactfean]

On the sohc chassis there are 3 coolant sensors.
1 coolant temp switch in radiator hose, for ac fan
2 coolant temp sensor, by the coolant inlet on the block for the ecu
3 coolant temp "switch" single prong sensor for gauge cluster, right next to 2 wire ecu sensor

On the dohc chassis there are only 2 sensors. One for the gauge cluster and one for the ecu.

[allenms240]

Ah, gotcha, thanks for setting me straigt

Ok if the car starts fine til it warms up, sounds like the coolant temp sensor, start it til it warms and dies, then disconnect the coolant temp sensor plug (red two pin connector) then try to start it

Nahh dude i pulled it off and the same thing happens with the motor. Except it stalls out way faster than in the video

[Armstec_S13]

Ah ok, damn I really wanna get this figured out lol

You have access to a boost leak detector? You could find any vac leaks with that....other than that I see a consult cable being good friends with you very soon.

Nah I really don't have access to one and I know its not a vac leak cause it ran perfectly in the other car, so I am 100% positive it is something within the wiring. Someone told me I'm lacking fuel or spark but the car starts right up so it cant be spark and I have a brand new walboro 255 fuel pump that worked well with my old motor in this chassis. The guy who sold me the motor said he ran it with an auto ECU and to try an auto ecu and see what happens from there but I doubt that will do anything unless my ecu is the problem. and if it is not my ECU I'm going to try a new wiring harness cause I think it is overall my main problem, I'm getting f*** up signals somewhere along the line...I can just feel it.

the only diff between the auto and manual motor is the TPS, they adjust the same but the auto will have an extra plug for the transmission kickdown signal. the auto tps will work just find on a manual and the manual ecu will work fine with an auto motor (as long as its a manual tansmission) an auto ecu can give you problems on your manual motor although i have never positively seen this confirmed or disproved with my own eyes.

I still say that you need to unbolt the ecu and flip that hoe around, turn the knob on it and check the codes, seriously what is holding you back??

[krash]

yea check out the ECU and see if that leads anywhere. However, for s13s you can run an auto ECU without a problem. I've been doing it for a long time. I doubt you have TPS problems because that will usually be relevant in places other than idle, and the car won't stall out like that, it'll just idle like crap

some people have reported erratic idle issues using an auto ecu on a manual, just saying.

[hoosier240sx]

It wasn't the ECU...could someone please just give me a simple fix and make me feel retarded so I don't have to take it to togue factory

Will turning the knob around show me codes even though my diagnostics have be cut out?

[moso]

yes. check the fsm

[hoosier240sx]

yes. check the fsm

ok so I turned the knob and turned the key on the car and the light turned red for like one second and then turned off. So I started the car and nothing happened, the light just stayed off.

[compactfean]

You have to turn key on, turn screw clockwise for 2 seconds, them turn counterclockwise and it will start blinking your codes. You cannot check codes with the car running. It specifically says this in the fsm, did you read any of it?

I dont even have a FSM, sir.

[moso]

theres a button here, its called search. if you use it, you may find what you need!

I dont even have a FSM, sir.
