Asked by Jun 26, 2017 at 11:42 PM about the 1991 Chevrolet Suburban V2500 4WD

Question type: Maintenance & Repair

The truck cranks but will not start. I
replaced the fuel pump has the right
pressure and hasn’t solid ground. I also
replaced the cap and rotor, ICM, Igniton
coil, the wires from the coil to the
distributor, plugs, and wires but still will not
start. Any ideas what needs to be replaced
