94 z28 no start
I just bought a 94 z28 with a lt1, the car sat for a long time due to a weak fuel pump, so I I had the a new one put in (trap door) car started good, and ran decent until I got out on the road and hit the gas pedal it would spudder but come right out of it, now here is where the problems start; drove the car 15 miles and it died, it fired back up, but it had a low coolant light on(coolant is full) so I had the codes ran and it showed code #43,42,36 so it was leading me to a new opti spark, so I took the car to my mechanic to have him look at it and 2 blocks from his shop it dies, so we towed it back and it sat for a week and he went to look at it and it fired right up and ran fine, well I went to get it, I could rev it up and it would still spudder and died again now its reading 0 fuel psi pump is cutting out for some reason...... any ideas? the car has a full tank of gas and new plugs and wires

Coolant light is no big deal, Just get a new one if you want mine has been on for years.I just did a head gasket job and it was running fine and then spuddering. I think it was do to still having air in the fuel line.

Fuel filter might be wanna be changed as well, while your fiddling with the fuel system.
