Need help ASAP!!! Unknown problem??
I have a 1987 Jeep YJ 2.5l 4 cyl. manual trans. The other day I was driving on the freeway doing about 70 mph when all of the sudden my Jeep just stopped running. The RPM's went from approx 3000 to 0. Luckily, I was able to get it to the side of the road without being hit. I tried to restart the vehicle, but with no luck. After having it towed to my house, I began to seek out the problem the next day. I've done some research and traced the Auto shutdown relay. I've replaced both of them along with the ignition switch under the steering column. No luck. I dropped the fuel tank and pulled out the fuel pump. Then connected it to a 12v battery. Fuel pump works fine. However there is no power to the pump when the key is in the ON or START position. Continuity from the relay to fuel pump is good. All fuses are good. I heard about a possible fusable link. I tried to track it down, but could not find anything. I'm at my whits end and don't know what else to do!! So I figured I'd try posting a thread on this site to see if there is anybody who might know something about this Jeep. It's hard to find a mechanic who knows something about these older Jeeps. Any HELP is apprecitated!!!
