1995 olds culass ciera fuse keeps blowing after replaced fuel pump.it never happen before fuel pump replacement.

There is a red wire close to the battery in the front. It's not connected to anything. Apply positive voltage and that will run your pump for testing purposes.

ecm1 is injectors not fuel pump ecm-b is fuel pump its more likely to be a faulty relay for the injectors, it would be a similiar design to this
this is for the fuel system, relay for the injector is nearly the same.

sounds like you could have something cloging the line so fuel pump is working to hard. try the filter see if its cloged up,maybe drain the tank and flush the system out.but you could be right with the pump itself going out again rare but could happen.good luck.

This normally happens due to short in the wirings.Or if someone has connected a stereo or some other electrical contrivance to the wiring harness (bundle), either under the dash or under the hood.To confirm this unplug the fuel pump wiring connections and insert new fuse.Then start the car and see,if still the fuse blows then its a short in wiring.But if the fuse does not blows then its faulty fuel pump relay or faulty fuel pump itself.So first replace the fuel pump relay and see,if the fuel still blows then its faulty fuel pump.But if the fuse not blowing then relay was the faulty part.The fuel pump relay located on the fuse box under the hood.---------This troubleshooting tips will help you locate the fault and solve it.-------Thanks.Helpmech.

FUEL PUMP WIRES HAS A SHORT OR FUEL PUMP BAD SHORTING OUT.BLOWING FUSE.CHECK FOR SHORT AT FUSE BOX AND AT THE FUEL PUMP WIRES.THE PCM GOES BAD SOMETIMES IT WILL SHORT OUT BLOW FUSE TO FUEL PUMP.

this is caused in most cases by a defective fuel pump, disconnect the pump connector at the top of the fuel tank, if the short stops replace the fuel pump inside te gas tank.

Yes the fuel pump is in the tank.The fuel pump relay is the first thing to check.Not to expensive,just put a new one in.Check all wires under the hood,and under the vehicle from front to back to see if there is a bad,torn wire harness.Think if any thing has been added to the vehicle where screws may have been put in,they could have cut a wire going in.Look for naked wires touching any thing.The fuel pump fuse can be part of the ecm also,so don`t just pinpoint fuel pump wire harness,sensors switches,etc,can be on the same circuit.If you have wired in a radio,or something similar,this could be the problem,maybe an over load to the circuit,so look for that also.If all this is fine,and you have changed the fuel pump relay out with a new one,then replace the fuel pump.If I can help,let me know.

the fuel pump is drawing too much current and is starting to go. Assuming you have correct size fuse. I would replace it.

The fuel tank needs to be emptied and removed from the car. The electric fuel pump is located on the top of the fuel tank. Hope this helps
