my cherokee will start and die but wont stay running i put a new tank, fuel pump and filter

 

On the driver's side inner fender near the air cleaner is a white ceramic doo-hinky about 3" long with a wire going to each end. It's called a fuel pump ballast resistor. If it's bad, the Jeep will start and run for only a few seconds and then die. Make sure the connectors are tight on the resistor and it's okay to bypass it if the resistor is bad.

 

ok check it then i bypass it and it still does the same thing it will start and die

 

See those 4 relays on the passenger side inner fender? Juggle them one over and see what happens. One is the fuel pump relay.

 

still the same starts and dies

 

You could have a bad ignition switch. How good are you with an electrical meter?

 

dont have one

 

have any other ideas

 

what about the injectors it has been sitting for a few years how do you clean then or can you clean them

 

You're screwed without a meter.............$15 tool.

 

ok did not wont to hear that but i will get me a meter

 

$15 meter or expensive guessing on sensors etc. We need to know if there's power to the fuel pump in the "run" position after the "start" position. Hey, you're getting a free education........

 

ya I thought I was doing good got it for free it had been sitting for 6 years they said it was a bad wire harness got it home poured gas in the throttle body and it fired up and ran new tank and pump and gas in tank and it ran good now it wont run I did run a new hot wire from the fuse box to the radio so it would work

 

Radio????? Let's get this baby RUNNING!

 

it was running when i did the radio but the radio not working could have some thing to do with the ignition switch
