5.7 Just cranks. Wont even act like it wants to start. Yes it has gas, yes the fuel pump is good... what else could it be? Never messed with this type of 350..... i do know they are known for a long list of sensor failures..
Test for spark at plugs. If none, check at coil... if none there break out the test light and your wiring schematic... should be a signal wire going to the coil from the PCM if nothing there break out check voltage output from cam sensor inside the distributor same with crank sensor.
My 95 just did this it was the ignition modual. About 40 bucks
dissy gear......

Cpi 5.7 your thinking the 5.3 and 6.0
tried new cap and rotor nothing.. , 60 psi, spark... gas.. still nothing gues ill pay good money for a shop to fawk with it
it does have spark and 60 psi fuel?
no service engine codes? kinda sounds like a cam or crank sensor.. i dont think it will spark without the crank sensor but with a bad cam sensor it just throws the timing off alot.
Did you check your fuses. I know my 91 chevy has a fuse for the injectors. Idk if yours does or not.
Gettin roll backed to the dealer in the am...... tired of screwin with it... itll be worth the money not having to anything but turn a key.... i will check the fuses though
let us know

Dude sometimes thats just the best way to go about it. Just let um deal with the head ach while you chil at home.
When it comes to troubleshooting id rather just hand it over!
Man the suspense is killing me.....lol.....They find out what it was??
i know its a little late but mine did the same thing last spring i changed the cap and rotor it fired right up they hav a bad cap design that lets moisture in an messes it up.
He already posted he tried that with no luck.
Well i had it roll backed to a shop monday... they got to it later that day... hoooked their computer up to it hit the key and it fired right up... WTF... they said everything checks out fine except the number 6 cylinder is mis firing... so 75 bucks for them to turn my key!
They find anything else out dave?
#6 cylinder is misfiring on fuel.. said clogged injector or there bouts.... other then that nothing.. said it was one of the cleanest hes seen come through. Said everything checked out superb
excellent!!!
Hmmm crazy! I dont remember if the ecm is under the hood or not? If it is... load up the connectors with dielectric grease!
Check and see if your IGNITION SWITCH is junk....(bad wire in under dash wire harness can do also)..........................when you turn the key ON.......do your idiot lights come on??
I had this same problem on my 95 chevy, engine turnd over, but wouldnt fire..........and fuel pump was getting power, I jiggled the wire harness under the dash............idiot lights came on......truck fired right up.
GM 1995 through 2001 trucks came with alot of faulty ignition switches..............common problem...............and one that alot of so called mechanics often overlook.
yeah the idiot lights always worked ..... hell of i know ... youd also think for being a 350 it would have more pep in its step... kinda doggy but o well runs decent and looks good!!
Oh, I think youre probably gonna have more troubles with this one. Im gonna guess and say you end up puttin a fuel pump or an ignition switch in it before its over with. ==dunno
