Hello all and thanks for allowing me to be a member here,
I have a 1996 Buick Riviera. It started blowing fuel pump fuses. I just bought the car about 3 months ago and it blew the 1st fuse after about 500 miles. Now its more like every few miles. Now it seems like when I press on the gas pedal it hesitates sometimes. I have popped 3 fuses in the last 5 days. If anyone knows what may be causing this I would really appreciate the info.. This has been driving me crazy.. The motor is a supercharged 3.8
I had to go from Cincinnati to SW Indiana Drove ( 270 miles ) The 1st 230 miles I had no problem at all. Then it snapped a fuse in town in a parking lot as I was getting ready to leave, Replaced the fuse and I drove another 30 - 40 miles the fuse snapped at 55 MPH. I put a new fuse in, I replaced the fuel pump fuse but now when I turn the key on it blows the fuse instantly. I dont think its the pump, The car drove great and it didnt hesitate, miss and had great power the whole time.
And ideas are appreciated. I think by this takes my mind that it isnt the pump and there is a short somewhere between the fuel pump and fuel pump fuse that is popping.
This may be the culprit but not sure I have a feeling it may be the Ignition Control Module.. I read that the fuel pump and Ignition control module are on the same fuse - can anyone help verify this? I have been looking and cannot verify this yet. But fingers are crossed
here is the thread I found that in: www.gmforum.com/showthread.php?t=265412
Someone also mentioned the Fuel pump control module that is in the trunk.
