Welcome to tgo, please loose the caps lock. Satrt with the basics fuel and fire it is possiable the icm failed.

 

WOW thanks for the quick response brother. Ill take a look at the ICM and see if i can get it tested. When i replaced the Cap and Rotor i did not change the ICM.

 

First test for spark, if you don't have any spark make sure the is power with the key on to the large pink wire on the side of the distributor. A bad icm can kill spark and or injector pulse. the next thing to test is fuel pressure and use a noid light to check for injector pulse.

 

STATIC fuel pressure, WITH leakdown time. Easy test; do you know how?

 

Thanks Tune Performance ill give all those a try..... Schrade no this is my first time en countering these issues.... if you have the time to explain it and its rather simple ill give it a shot....

 

Get a fuel pressure guage - just like an air guage for a tire.

There's a fuel pressure guage port on the fuel line - Schraeder Valve - snap it on quick, to not let too much fuel out - might not be too much pressure on it anyway.

Turn the key on, listen to the fuel pump prime the line, and observe for spec fuel pressure. Write immediate pressure.

Then note the leakdown time. Write down 1 minute, 2, 5, however it goes down. Post up.

You can get a mechanic to do it, but he'll charge as much (or more), than the cost of a guage.

 

Right on third gen brothers...... for all your help..... looks like a the new fuel pump I relpaced two weeks ago was defective..... shot 12v directly to the fuel pump and nothing.... So I check the pump relay and the fuse bot working perfect..... pulled the pump... replaced it with a new on and bam working again.....

I JUST WANNA SAY THANK YOU TO THE THIRD GEN USERS AND FORUM..... YOU GUYS ARE ****ING AWESOME.....
