Last night i was driving home and when i was coming out of a corner my jeep died tried to turn it over it cranks but seeing I have no fuel it won't start come to find out she popped a fuse tried to replace is and it just kept popping them so I think it's in the wiring some where what do y'all think?

Change your fuel pump, thats the same problem am having. Am changing mine this week.

Before you mess with the Fuel Pump, try changing around the fuel pump relay under the hood. mine did this pulling out of the gas station the other day. All the relays are the same under the hood if you need one in a pinch, but the things only cost about $8 new and they're cheap insurance to have around in the glove box.

A fuse that blows immediately won't be cured by swapping relays, it indicates a short circuit that must be found and repaired before anything else is done.

Well after running around like a chicken with it's head cut off it seems to be the PCM were going to hook it up to a obd reader and see what pops up but now we have the pump working but no spark and were not sure if the injectors are workin any ideas before I dump money into a new PCM ?

Have you determined why your fuse is blowing?

A scanner won't tell you that.

Well guys figured it out got a new PCM from a jy for 35 bucks put it in and she fired up like nothing was ever wrong . I'm guessing the reasone the fuse was popping was a ground issue with the PCM . Super gald I got her goin and didn't have to spend much coin thanks for the help !
