Customer Question
Got the fuel pump...

Got the fuel pump replaced a week ago and since the first time I drove it it has been blowing ecm fuse! Now it won’t even crank cuz fuse blows as soon as u turn the key

Mechanic's Assistant: Can you turn the steering wheel at all? And what about the key? Is it worn or damaged?

Yes I can turn wheel and no damage to key.

Mechanic's Assistant: What is the model/year of your Chevy?

Had the bed taken off yesterday and found a green wire that had a wire nut on it so I spliced it together and taped it up changed fuse and it crank up then when I went to leave an hour latter I barley got of driveway and fuse blew

Mechanic's Assistant: What year is your Chevy?

1995 s10

Mechanic's Assistant: Are you fixing your S10 yourself? What have you tried so far?

Took the bed off look for a bare hot wire and couldn’t find one

Also wounderibg if it cud be the computer if so how do I tell if it is
Chevy Mechanic: david craig, Auto Mechanic replied 8 months ago

if the fuse still blows then the problem is the wiring to the fuse box. if it doesnt blow then the fuel pump he put in is bad.

Chevy Mechanic: david craig, Auto Mechanic replied 8 months ago

Customer reply replied 8 months ago
Ok
Chevy Mechanic: david craig, Auto Mechanic replied 8 months ago

you need to disconnect the pump. if the fuse still blows, then you need to start tracing the wires from the fuel pump connector all the way to where they go into the fuse box. look for any kind of damage, chaffing or arcing

Ty for ur help I appreciate it. If i don’t fix it I don’t get to see my daughter for Xmas.
Chevy Mechanic: david craig, Auto Mechanic replied 8 months ago

if you take your time. be very thorough in the inspection of the wiring, not only looking at the wires but feeling them for damage, you will find where its shorting
