The suv ran great for a week, then back to its old tricks, impossible to start. I have replaced the crank sensor (coil pickup), rotor, fuel pressure sensor, fuel filter, fuel pump, battery, spark plugs, and plug wires. It has spark, and holds between 55-60 psi fuel pressure. I simply cannot figure out why this vehicle starts/refuses to start so sporadically. Any 4.3 vortec specialists out there that can give me a clue in the right direction?
