Having problems with your Chevrolet Chevy ?

2000Chev. Venture when stopped SOME times will not start, just Silently DEAD. I keep blowing out the PCM/ABS fuse. Seems to happen after auto warmed up, then shut off and left for few minutes, try to restart and cannot. Last time this happened blew out 3 fuses in a row. Local mechanic has looked for a short, has the wiring diagram, has check wiring and wiggled the wiring to each compnent with ign on to see if he could duplicate blowing of the fuse. Inserted new fuse, everything works fine. Th

Dear sir/madam,

They are bad to blow this fuse when the fuel pump is going out. When\015\012you get on the gas pedal, the demand rises, and the pressure drops to a\015\012level to make the pump run more often, so if its going bad, the pump\015\012gets hot enough, or is shorting out internally to make the fuse blow.\015\012Since this is a 10 amp fuse, the pump must be getting pretty hot to\015\012blow it. The throttle position sensor wouldn't blow this fuse, as it is\015\012not powered off this side of the power supply, and works to ground\015\012anyway. Do this; When it blows again, feel the wires that go into the\015\012gas tank to see if they feel hot. You can also feel the wires going to\015\012the TPS, and you will see what I mean. The fuse you are talking about\015\012does blow when there is an issue with the fuel pump, or a short in the\015\012harness going back to the tank from the ECM. This system is also wired\015\012through the oil sending unit, so you may have to check there as well\015\012for any wires shorting to ground.

good luck
