i have a electrical problem my fuel pump fuse pump fuse keeps blowingi replaced myfuel pump should i just get a new harnessor try to find the short

 

well if you're real handy you can check the underside of the fuse box for any loose connections. and if you dont see any there i dont know.
i know im not much help. but i try, really

i know when i had an electrical problem its best to just take it to a dodge/chrystler dealer. it saves a lot of money instead of taking it to a garage and have them try and find the problem.

the garage spent 4+ hrs trying to find the problem where the dealer had the problem diagnosed in 15 mins. thankfully the garage felt sory for me and didnt charge me for the labor.
it was the radiator relay switch.

 

Ive heard of this a few times and it was the o2 senser wires that had melted and was grounding and making the gas pump fuse pop all the time not saying thats it in ur case but its worth a look,,hope u find ur problem,,let us know what u find,,

 

^^^Thats what I was gooing to say. Check that and all your grounds.

 

where are the o2 sensor wires

 

here's a pic i hope it helps,,,

 

Upstream is on the exhaust manifold and the downstream is just after the cat.

 

nice timing das,,,lol its cool when people work together,,,i hope we were usful,,good luck.

 

the o2 sensor wires, you can find them just by looking at your exhaust. they will lead to a sensor on the exhaust and they are the only (sensor, wires) on the exhaust, so finding them wont be hard. but i will personally worn you. If you are not good at wiring for your own sake do not tamper with your vehicles wiring. You can really screw alot of things up. most ppl dont realize that alot of sensor wires arent 12v but instead they recieve a signal voltage. signal voltage could be ( depending on the sensor ) like 2.45V. so then u go in and fix the wires with a crimp in repair. the crimpconection not being solid now ur signal voltage is 2.35 and ur ecm thinks something is wronge. yeah thats the kinda stuff i deal with like once a week or more! it sux.

 

Couldnt the pcm be another reason why they are blowing? If its bad
