99 5.7 vortec, Drove home fine next morning won't start, pulled spark plug wet with gas. Pulled pleum fuel pressure regulator leaking all wet under intake(gas) put on new regulator after a little effort got it started, Drove it for two days no real problem little miss, put in new set of plugs. Ran great coming home that day (friday) Monday morning won't start again, pulled plug all wet, pulled pleum no sign of any leak, put in new plugs still no start after turning over for several seconds it dose try to start but never dose. Any ideas, Have replaced O2's,map,throttle sensors, IAC motor. Injectors don't seem to be leaking. Thanks Ghost

It'll be interesting to see what the fuel pressure will be...whens the last time the fuel filter was replaced?

fuel pressure 65, two months on fuel filter. Has spark, has fuel, we are now checking to see if timing is correct maybe spark and fuel are not together LOL

onother thing that goes bad on the 5.7 vortec is the distributor gear.pull the dist out , the gear is probably so wore out you can shave with it.........

Well guys it was the distributor cap, Can't figure it pulled plugs had fire? Put on new cap and rotor started right up. Thanks for all the replys:banghead::rofl:
