Re: Help before I go crazy. 99 suburban 5.7 vortec wont start.

Start simple..

check engine compression...

check to make sure your distributor is in time correctly (stabbed correctly)

check for spark

check fuel pressure with a gauge

you need compression, fuel and spark for the engine to run.... one of them is missing....
