Customer Question

Hi Paul, I have a 1997 GMC sierra. It sometimes will not start and other times it starts and runs just fine. Fuel pump, fuel filter, crankshaft position sensor, plugs, wires, alternator have all been replaced in the last year or so. It started gradually. Just once in a while hard to start then over a month or so to the point it takes me several minutes to start

HI there, I am Cam. Can I get your first name please?

Does it fire if you put a bit of fuel in the throttle, does it fire and run?
