I have spark, timing is dead on, have fuel and good fuel pressure, cranks, i noticed that the iac valve dose not click anymore when i hook it up and un hook it, but if i jump it to that battery and the valve openes indicating that the iac valve itself is good. It just seems that maybe some relay or fuse or something is holding it up. Need help thanks

 

bump this one got me?

 

well if you think of anything to try let me know. I've so far gone as far as switching out the ecu with an identical one. Thanks man.

 

see well my thing is if it has spark and fuel and cranks over there should be no reason it won't atleast start for a minute or start and just run like crap, i have seen this one other time my friend broke a valve spring retainer and the car wouldn't start its a long shot but i'm pretty lost

 

you are getting fuel to the injectors? Crank over engine, pull plug and see if they are soaked, or have fuel on em. Test your injector pulse (if you can)...

 

try checking the grounds. a lot of times this is the problem and a lot of people overlook this.

 

i hAD THE SAME PROBLEM 2 days ago i test for spark had it later that day i test again and no more spark i had to chang the dizzy and spark plugs and it start rite up! also check the main relay that causes the fuel pump to come on and off

 

Well it looks like i was wrong cuz i have no spark i thought that i did but i don't. I checked the distributer according the haynes manual and it seems good i even replaced the ICM inside, but still no spark. I feel that something is telling the ecu to not deliver spark but i don't even know how to tell or what sensor would cause that.

 

I had the same problem U gonna have to change dizzy plugs spark plugs cap and rotor!
