I have 1998 chevy k1500 with the 5.7(350) engine. It's not starting on some days. Other days it well. It also losing oil psi. Was told it was the cap and rotor replaced them. When I say the truck
Not starting I mean it is starting then kills out 1sec after turning it over. -Don , Columbus
A few things I would check
1. Bad fuel pump.
2. The Mass air flow sensor might be bad.
