I have been working with this truck all summer and fall to get it running and reliable. Its a 1998 chevy silverado Z71 extcab 5.7L Vortec.
This vehicle has gremlins in it. I swear. So far I have replaced the entire distributor assembly, new plugs, new wires, new fuel tank-(rusty), new complete fuel pump assembly-( Twice), new coil, new ignition control module-(twice)first one was the economy style truck would start and run for a couple of days off and on then replaced it again with the code 1351 came up again then, the second one was the premium style, changed it yesterday truck will only turn over and when you let off the key it will pop back through the air breather ( K&N Style)had the fuel pressure checked, they said it was ok. One day this week I went out and turned the key and it would not start. So I shut off the key and turned it on again and pumped the hell out of the throttle while the engine turned over and got a pop. I kept pumping the throttle fast and after 3 attempts of this it started. And I took it down our side road and hammered it down. It ran great. Lots of power, and idled excellent. Shut it off and it didnt even take a whole revolution and it started. I am in wisconsin and the temps here are 26 degrees. I went out today to try it and it is back to not starting again. Just back pops through the breather again. Its like this all fall cant trust it when it does run to take it anywhere. What do I do? Steve
