I'm looking at buying a 1988 Jeep Cherokee Pioneer with 128K on it. The seller is asking $2800 for it, is it worth that or what would be a resonable offer. They claim it is 'clean and runs great'. I know I probably have to check it out for myself, but I also don't want to make a bad purchase. Thanks for your help.

I recently purchased a 1988 Jeep Cherokee Pioneer in great condition with a 166,000 miles. I bought it on Friday it ran great, Saturday no problems. Sunday I took it to the grocery store early in the morning it ran fine although slow to start. I brought it home. At about noon I went out to start it it wouldn't start after about 5 tries each hour, it just wouldn't start. The engine turned over fine, but wouldn't fire. In disgust I slammed down the hood. My neighbor who was watching me came over and asked me if I wanted him to look at it. I reopened the hood, he said "crank it" and it started right away. Da, is my neighbor just gifted. Got ant ideas?

This slow start is usually caused by the fuel pump going bad. It's supposed to keep 30PSI in the system after you turn the car off - a check valve goes bad and the pressure isn't held, and when you go to to start the car, the pump has to refill the lines before gas gets into the engine. You can buy a fuel pressure gauge for around $30 and the 4.0 has a test port on the fuel rail along the intake manifold. Screw it onto the fitting, start the Jeep and then turn it off... pressure should stay up - if it slowly bleeds down to zero in just a few minutes you have a bad check valve. Hope this helps.

If you need to replace the fuel pump, get one from the dealer... aftermarket pumps suck and will fail in 20-30K.

I bought an 88 Cherokee Pioneer with 183k miles on it. It runs fine and all, but when I take it onto the highway and go over 55mph, it will randomly, at any moment, start to shake uncontrollably. It's pretty scary. It finally stops when I slow it down to 25mph, but will happen again if I stay over 55mph for too long. Any thoughts? I'm really hoping there is a quick, painless, and cheap way to fix this...
