Been working on my jeep on and off, mostly done. But life keeps getting in the way.. Anyway, I'm having power issues. My fuel pressure is ~20PSI with vacuum connected, and ~22 no vacuum. Seems low, right? I changed the diaphragm on the rail, same results. There is no ballast in line, direct wired. I'm thinking the fuel pump. Just looking for ideas before I order another pump.

Hello, I have recently became the new owner of a 1989 jeep comanche pioneer. It's 2WD and a short bed. She's got a nice patina on her. And I kinda like it. But I also would like to bring her to her former glory. But seeing its 2WD it wouldn't be a good mud truck or a good off road truck. My plans are to turn her into a race truck. But my first question I have for it is how else could I lower it in the back. For the front I can get some new coilovers for it but in the back I do not know how to get it lower. Would I be able to put a "shim or spacer" between the axle and the leaf spring to make it lower?

So 3 weeks ago i bought an 89 comanche short bed 5 speed with 91 thousand miles on it clean frame and good body. I paid 1000 doallars at police auction. I finaly got it home changed the oil and filter, drained the fuel and added new tried to start it, i had no spark. So i started to check things out so far i have replaced the CPS, Coil, Cap, Rotor, Wires and ICM was going to change the plugs but after i pulled one and i looked brand new i decided not to, after all that got it to start, but it would stall while driving. I replaced the the TPS and it was good to go or so i thought. It drove fine for three days. my brother had it on friday and said it ran great, actully better then his 90 cherokee when it was renix (we just swapped in everything from a 95 so i have an extra renix engine and majority of sensors) so saturday i go to drive it and it was running like total garbage and got worse till it stalled. now it starts runs so rough that it seems like i have muitple cylinders missing and there is no throttle input. I checked my fuel pressure its at 38 pounds. I'm going to change the spark plugs to see if maybe i fouled one or mutiple out while trying to get it to start and I'm going to change my fuel filter because i wanted to do it any way. So what should i check after i do the plugs and filter. I'm leaning towards something fuel related because it got so low (less then 1/8th) and i don't know the quality of gas that was in there. As far as service records or any history i don't know any. The only tring i know is that it sat for at least two years at the impound.
