im helping out a friend that has a 95 camaro z28 with the LT1 (obv)

about 2 months ago at a local show he was doing a burnout and when he decided to stop the car acted like it was going to stall then it did stall but started right back up then died again.Now the car has no spark.

heres a list of things ive changed and or tried.

changed opti.
changed coil
changed PCM
checked all fuses and visible grounds

the car does have a factory alarm in it but i dont think that is the cause,but i could be wrong.. PLEASE HELP!

 

Get a voltmeter/multimeter and try this out:

thanks man ill give it a shot.

 

Sounds good. And you are for sure it has no spark or you assuming this since the car died? It almost sounds like a fuel pump or fuel filter issue. Just seems weird but could have an intermittent bad wire somewhere.

 

im %110 positive its not fuel related.i can smell fuel while its cranking and the fuel pressure goes up to 40 psi.

you can tell by the way its cranking too that there isnt any spark getting to the plugs.

 

Ok,so now when I check the spark plugs with a spark tester it says its getting spark and I can smell fuel..why won't it start??? I'm getting frustrated

 

Did you replace the Ignition Control Module under the coil too? I had a 96 Z28 that did the same thing but I was just driving and it quite. It ended up being that little module. Apparently since it is bolted to the head it heats up to much and gives out. Its an easy fix if you havent done it already.

 

Yup replaced the coil and icm as well

 

I would try to bypass the alarm might not be it but can check it off the list.

 

I did replace the opti harness,I'm not sure how to go about disconnecting the alarm..
