Why does my comanche die?

[creep_in_the_jeep]

i have a 88 jeep comanche 4x4 with the 4.0 automatic and i filled the gas tank full till the nozzel kicked off i was driving back to work and it just died. tried restarting it and couldnt get it to fire but when i pushed it into a parking lot i tried it again and it fired and runs fine i looked at the wires and ect to the pump and it seems like fuel is splashing out from around the pump and seal. could it be too full and that caused it to die? help please don't want it to do it again thank you

That random stalling sounds more like the CPS.  Over filling a gas tank, which I'm not convinced it is anyway, shouldn't cause an engine to stall.

Probably a coincidence.

 

Your CPS can be tested. Click on the link below and go to Tip 7.

 

Since it's an 88, I would complete Tips 1 through 5 thoroughly before doing anything else.

i found the problem the nipple or adapter on the fuel pump broke off but now i can't find just the fuel pump assembly. ive checked everywhere does anyone know what i can do? i also heard that the tank out of a 88 dakota will fit in it that way you can find a pump easier is that true? also i heard that the fuel pump in the 4.0 fuel injected has a high pressure fuel pump? thank you

Don't forget to do the Tips in the near future.

i think its the c101 box i have troubles with it dying at idle and sometimes i just cranks forever and the fires and sometimes it sound like it wants to stall when driving

Good place to start, but don't forget the others....
