i was driveing when my car just started to idle at 200-500 rpms and would bog on take offs.. i was on the free waay when the car just died. i tryed to pull the codes on my 93 si stock and the ckeck engiane light just stays on im not getting any codes i have done it before, it not getting sprark or fuel..

 

could be your alternator but u have to push the pin or whatever u are using all the way in the ecu plugs.u will get the code.i tried to get the code for the very frist time and i didnt get the code so i tried to push the pin all the way in and then the cel started to flash.
and also do u have a check battery light on ?

 

i know tryed all of it the car turn over like it should just not getting spark or fuel the fuel pump is good. dizzy is good just not getting anything and dont know y help me lol......

 

or could it be the main relay?

 

Check the voltage of the battery. If its drained, the alternator went bad or a bad ground or connection somewhere. If you think th ecu id bad, pop off the cover and look for burn marks. If something burned, the bottem cover usually has a burn mark on the plastic.

 

checked the grounds... pulling the ecu,,, what happens when the main relay gos out? and it cant be the alternatoir or the battrie beciuse it also getting no fuel..

 

to check the main relay, turn the key. You should a quiet hum while the CEL is on then stops when the CEL turns off. Thats the fuel pump priming.

 

YEA YEA... it not turning on the fuel pump i hotwired the fuel pump and then it comes on.. it get no fuel or spark or fuel all it does is turn over from the starter.

How did the ecu look? Thats a lot of stuff to go wrong all at once.
PM sent.

The main relay controls the power to the ECU and fuel pump.

However, when the main relay fails, it typically fails intermittently in hot weather. Once the car is cooled back down, it should start. Also, the main relay causes a no-fuel condition but the car should still be getting spark.

If you're not getting spark, look elsewhere. You may have a bad ground or some faulty wiring.

 

the oil light and check eng light just stays on i cant pull any codes i cheked all the grounds.
