Where is the fuel pump relay fuse? Or if anyone has any other advice on this issue...
 

A year or so ago, my fuel pump went out. A mechanic I brought it to fixed it very cheaply, the issue was a grounding issue causing the fuel pump fuse to blow repeatedly.

The problem has back, but I am having trouble finding the blown fuse. The fuel pump fuse in the fuse box is fine, so I want to check the "in line" fuse, but I can not find it. I have seen a diagram for it here: https://www.justanswer.com/uploads/g..._fuel_fuse.gif

but I just can not find the darn thing. Here is an actual image of the area I am looking in: https://imgur.com/a/JZmIApL

The 94-96 is probably in, or on the fuse block at the passenger's side rear corner of the engine compartment. A grounding issue needs to be fixed before you can expect the blown fuses to stop.

I'm a little puzzled by the explanation offered by the mechanic.
I have never seen where a poor ground caused any fuse to blow. The fuse is there to protect the components and wiring from an over current problem.
The way that is confirmed is to measure the current draw of the circuit which in this case I believe you feel is the fuel pump circuit.
Since the fuse was blowing all the time , it indicated a short circuit path to ground. If you remove the ground path the fuse can't blow, but the circuit is not complete either.
Something is providing a path for the current to get to ground aside from the path through the fuel pump motor.
There is more here than just one possibility. There is the fuel pump , the relay that gets energized and provides power to the pump , and what activates that relay.
What we need to know is , the year and model of your vehicle. Most times the fuse panel is on the passenger side inside the vehicle. Some later years have the fuse/relay panel under the back seat with the battery. Depending on the year, what may have been altered, and anything additional you can offer should help come up with something worthwhile as far as a diagnosis is concerned.
Anytime someone installs an inline fuse , something has been added, altered or the original problem couldn't be found.
Sorry for the long winded post, but ,,,, well let's see what info you can supply and we will go from there, thanks.

If you look at the supplied picture, you will know it is a 94--96 B body GM. A fuse only blows when there is too much current going through it. Either there is a short to ground between the relay and the pump, or the pump motor is compromised. I had a relay solenoid take down a fuse, but it also fried the relay solenoid at the same time. A VOM is your friend. Check the circuit from one connector to the next, and check the relay for shorts.

Hi Fred,
Looks like we are on the same page !


I don't know for sure if the pix provided is our poster's actual vehicle, I think it is something he found that shows what he might be looking for.
We may know what we should do , but I have found a lot of folks aren't sure or don't have the equip or maybe they just don't want to get involved and are looking for some answers.
That is why I requested the info of year, model etc. Unfortunately, some folks doing vehicle repair come across a little short when it comes to basic electrical testing and it is possible our poster did not get the entire picture of what the mechanic found or did. To us this is basic stuff, but to some folks it might as well be Greek, French or other.and they are seeking answers or maybe advice. What do you think?

I think we need more information.
