Hello there and thank you for contacting JustAnswer, sorry to hear about your car I’ll do my best to help you solve this issue, have you checked your fuel pressure and fuel filter?

just replaced fuel pumpbrand new
Automotive Expert
Do you have pressure? Can you check if it’s between 45psi and 58

no way to check
Automotive Expert
Ok are you getting fuel through the injectors?

i think so
Automotive Expert
It’ll be great if you can get pressure reading.

im trying not to take it to a shop
Automotive Expert
Sometimes auto parts shop can loan you the tool.

im also limited on what im capable because im rural and no other vehicle
Automotive Expert
Ok give me one moment to gather some more thoughts.

i guess i have to get it towed to a shop
Automotive Expert
We’ll see what we can do before that.

okit didnt give any codes. when disconecting battery to reset for the new pump which terminal cable do i take off
Automotive Expert
The positive

thats what i thought. i did the negativecould that be the problem?
Automotive Expert
Resetting the pump?

computer for vehicledont i need the computer to reset?
Automotive Expert
I thought you just wanna reset it by removing battery terminals?

not the pump. but yesdoesnt removing cable from battery and waiting a few minutes reset the computer of jeep to read new pump?
Automotive Expert
You can try. I know some cars get reset that way.

if i did the negative it wouldnt reset the computer huh
Automotive Expert
Sometimes removing the battery terminals only resets it for a while. If you’re talking about the whole module you might need to go to dealership for that.

or does that matter
Automotive Expert
Just remove both terminals and see.

ok is there anything else i can try?
Automotive Expert
Not at the moment without the pressure readings I cannot suggest anything.

ok. thank you
