Should start this off by saying this 400$ jeep has not been the slightest bit reliable, but it's gotten me home every time! This is a 1987 jeep Cherokee 4.0 4x4. So the other night I was driving along, and all of a sudden I felt a loss of power. It got steadily worse, it would revv up to about...

I need an 89 or older, it's got two different vacuum chambers. Also not one in a junk yard within 80 miles

Hey guys back again. Looks like my vacuum reservoir is broke beyond repair, and I can't find onw within 80 miles from me and none on the internet so far. So does anyone have one from a pre 89 they'd be willing to sell me? PayPal ready

I think I've figured it out for anyone having the same problem as me. It's that big vamuum chamber under the passenger side bumper. I though it was only for cruise control but aperiently if there's a leak in it it will default to only blowing from the defrost vent. I'm going to go putz with it...

Looks like I'll be playing a game of hide and seek tomorrow. Some one had mentioned it could be my grounds. Any ideas on this? And if so where would the main ones be? He never said the grounds to the pump or just in general

Any clue where the ballast resister would be? At least general location?

Thanks for the warm welcome and the sharing of your experience. I've gone ahead and replaced the pump and got a good proper battery. I've checked and cleaned the fuel pump relay, and it's clicking and acting as it should. Still no fuel pump clicking on though. I'd hate to go buy some nice...

Thanks terry! And yeah inline 6, I've been doing a little reasearch and before I go ahead and replace the fuel pump, im going to check the fuel pump fuse and relay.

Hey guys first post so don't butcher me, but I got my first car, a 1987 two door jeep Cherokee sport 4.0 and the problem is it's not getting fuel to the injectors. When you spray starter fluid into the intake, it will fire for a little but not much. Something I noticed is the the injectors are...
