Customer Question
Hello, I have a 2001...
Hello, I have a 2001 Montana, I was driving home on interstate when the rpm gauge and battery light would come on as the motor would stop firing for 2 to 4 seconds. The van would then jerk when the engine would catch and engage again. this was sparatic and cut out at least a hundred times as I limped it home for 30 miles. I have changed the fuel pump, fuel pump relay, fuel filter, 230mv coming back on ground from pump. Cleaned and put new ends on grounds. The wire behind drivers seat I installed new connecters 2 years ago and are in perfect shape. Have hot wired new pump to a remote battery in van and still cuts out. What do I check next? Runs good till it is on the road for 1/2 mile then it starts to cut out, It will idle perfect for hour and can throttle up 3700 rpm before it must hit a limiter. No codes are in computer. Where to next? Thank You Bill

Welcome I'm Chris aka Moose

Do you have a diagnostic tool so you can monitor the cam and crank sensor signals. I would like to know if there is a reading issue from them effecting the injector pulse and ignition coil signal. Since you have ruled out the pump and I presume the pressure it has to be losing spark or injector pulse causing this parcel stale event.

Hello again, I am sorry you were not pleased with my help.

I hate that you paid to get an answer but left, what appears to me, not satisfied.

Just so you know I am still here and available to help any day. We can start over fresh or just pick up where we left off.
