Fuel Pump

SBHoney · 03-18-2007, 08:47 AM

I have a 95 blazer and the fuel pump is not kicking on. Before I start to remove the fuel tank I am going to check and see if I have power going to the fuel pump. I have allready checked the fuses and the relays. If I do not have power going to the pump is there anything else you guys know of that would cause no power to the pump. The truck was running really bad before it would not start at all and it did through a P0341 code. I appreciate any help before I start this project.

Not too sure how you are going to verify voltage at the pump without actually getting to the pump, but more power to you. It is entirely possible that the wiring has become severed, or pinched. I am comfident that it is not a short, the fuse would have blown if this were the case, The same should hold true for the pinched wire. At some time during the time the wires became damaged, the voltage side would have had to have gone to ground, and the fuse would have blown.
I am also not really sure that the code, and the pump are related in any way. The important thing is to get the truck running again, so you can continue to troubleshoot the code.
