1991 cherokee fuel pump
ok,
Question 2...When i get in to start it up, i have to turn the key on the "on" position and i have to wait (depending on the temp. outside) from 15 min. to an hour or so when its really cold out for the fuel pump to kick on...then she,ll start...any sooner and it just cranks. Changed the pump and relay. Workin on the postive cable to the power dist. box. Any suggestions? 4.0 automatic

replaced ballast resistor last summer and it did not work either...would the ecm maybe cause a loooooong delay to reach the fuel pump...I also started looking into the positive cable thinking it might be a fusable link?...any thoughts?

What is this gonna do?
Just a thought, instead of tossing more and more money and time into this truck why not take it to the nearest stealership and have them run diagnostics on the truck?
I took my fiance's TJ to one recently. To me it was worth it. My time is worth alot to me, and I wanted it done 100% right, no questions asked.
So that $100 was well spent, adn I didn't have to waste alot of time diagnosing/playing with incorrect parts. Went right to the problem and fixed it.
Just a thought.
