#98150, "Still no start after new ECU, I am getting pissed now."
Okay so I swapped in a new ECU and the car still does not fire...
Here are some side notes, so if anybody thinks of any idea's or anything to try, PLEASE let me know, I need this bitch to run, lol.
When cranking, my Snap On scanner IS telling me the following: I have a cam/crank signal. I have TPS value and voltage. ASD and Fuel relays are both okay. Fuel pressure is fine.
I did a spark test with the scanner and I got spark to both sides of the coil pack.
BUT when cranking w/ out doing the test w/ the scanner, there is no spark.
Timing is dead on, compression is 180 across the board.
What else can cause the ECU to not see spark? The engine fuse is okay too.
THIS IS DRIVING ME FUCKING CRAZY GUYS, I have searched like crazy and found nothing really, and if I did find something, I tried it and nothing worked.
Can someone point me a in a good direction or something PLEASE!!!

So why did you replace the PCM then? Check your battery voltage while cranking if it drops below 9.6 V then the PCM shuts down. If you still have problems i live in hartville ohio (between akron and canton) i can come take a look at it. Let me know.

I was thinking this. Or possible bad ground somewhere. Spark signal starts at the Crank sensor-----ecu-----ASD-----Coil pack.

well DUH!!!

lollers.

Fuck you DJ, you are a dousche.
The Snap On procedure on our software on the computer had given us a test to run called 'Test w/ no codes in PCM'.
We ran this test, testing multiple things and if everything checked out okay after the test, the last thing it said to do if everything was test alright, was to replace the PCM...

So, your getting spark and fuel fine, and your ecu is new and sensors work. My only other suggestion is ground, only because you have the 2 major things to start your car fuel and spark, also you say your battery is fine. I may be wrong, but it has to be something small since everything you checked out is fine. My car wouldnt start on me 3 times, 1st was ecu, 2nd was little ground cable on the front of the block above the starter, and 3rd was asd relay. The only way i found out it was the asd relay was checking both relays to the fuel connection and making sure the fuel pump primes when the key is turned on. Hope you figure out.

my fuel and ignition relays are different so i cant swap them out to see if the other works.
