1999 Chevrolet 5.7. Hard to start after sitting.

Asked by GuruTXG3N Apr 17, 2019 at 02:14 PM about the 1999 Chevrolet C/K 2500 Extended Cab LB HD RWD

Question type: Maintenance & Repair

I have a 1999 chevrolet 2500 with a
5.7 and a 5 speed standard
transmission. Have to pull start after
the truck has been sitting a day or so.
But once it's running I can turn it off
and on all day long. I replaced the
starter and the spyder Injector with the
fuel pressure regulator.

Make sure battery has a full charge and connections all good. Try cycling the key on and off several times before you crank it, see if it helps? If it helps check your fuel system. Fuel pressure, key on engine off, 60--66 psi fuel pressure. After it starts it will run with less pressure. In the past, have seen service bulletins about poppet valves sticking with that spider fuel system. The first start up of the day has a problem, after that the vehicle will start and run fine the rest of the day, till it sits overnight, then the same problem, again. The cleaning procedure I saw for poppets was a shop procedure. I don't know if you changed out the poppets as well?
