Unsolved mystery!!! 01 z28 problem plz help!!!!
Alright so i just uncovered my password for LS1tech over the pile of dust since 05' lol and haven't had any problems with my car since (that'd be a big lie)! But this one has seemed to STUMP! and i mean STUMP everyone i come into contact with, or ask... Mechanics with 25-30yrs experience, FORGET IT! Starter & alternator repairs, nothing! Auto part stores, ha joke.. Even wal-mart! imagine that! You name it! I've asked!! Now i am coming to you guy's.. THE BEST AROUND!!
The problem: 01 Z28 will not start!!! Starter is good, car turns over... I have been jobless for a year so my car has just sat for months at a time, back in Dec. of 09' it would take bout 3-4 cranks to start, then 5-8 cranks, then just went dead!
Solution: NOT FOUND!
Results: I have tried everything man, from charging my 4-5 yr old Red top optima battery, having it tested at wal-mart (good battery). To having a friend run a diagnostics with his 10k Snap-on computer to find the problem, nothing throwed or gave there! So i ripped out the alternator and had it tested, needed a new regulator, replaced it, and still won't start!!!! Dude i am stranded and do not know what to do! Please help!
IS IT THE FUEL PUMP???
End result: MY CAR IS HAUNTED!!!
Only thing i haven't tried is handing my baby over to a Chevy dealership and having them charge me out the A-hole!!! NO FUN!!!!
Please help.. The big car show ROD RUNS in Pigeon Forge, TN is next week, I would love to have it up and running by then! I appreciate every comment or concern! THANKS

1-Compression check the engine....if it checks out, then:
2-Check to make sure that the engine is getting spark....if that checks out, then:
3-Check to make sure that the fuel sysytem is working (ie,55psi in the rail, good filters, etc..) if that checks out, then:
4-Check to make sure that the fuel injectors are "firing". If not, start looking at wiring/grounds or ECU.
Unfortunately, there is no way that any of us can tell you exactly what is wrong with your car....unless we were able to go through the above-outlined steps to get to the bottom of the problem. This is going to require some work on your part, as in actually testing the car yourself.
Start working the above steps, and post your results here....we'll give you some direction on how to proceed, and help you get to the bottom of it quickly, if you work quickly.
Best of luck.....I'm willing to bet it is nothing major that is wrong.
To test the relay you could swap it with the starter relay and see what happens.
