Question about 1989 Jeep Cherokee

1 Answer

Have a hard starting 1989 Jeep Wagoneer. Acts as if the pressurized fuel system has lost that pressure. Have changed the fuel pump, no change in problem. Have heard of an ''injector primer relay'' but can't find such a beast mentioned in manual.

Check the resistor on the left fender back near the master cyl and see if its burned out. Also, you don't have to be loosing pressure from the pump, could be from the injectors as well. If you don't hear the pump right away when you turn the key, check the pump relay in the power distribution center...it may be balky.
This is one of those problems that really need a gauge test on line to see what is going on...guessing is hit or miss! Hope something here helped.

Check the fuel pressure.It sounds like you may have a weak fuel pump.If its not within the specs then replace the fuel pump and filter.

I have a 1988 Jeep Grand Wagoneer that seems to be losing oil pressure then dying. I just changed the oil and the levels are fine. Not sure where to start... any ideas?


if this just started when you changed the oil and filter,then it might be the filter,it did it in my 89 jeep so i changed the filter to another brand and my oil pressure came back to normal.so i would recomend and stp or k&n or wix filter.if that doesnt then start looking at the oil pressure sensor and wire lead.you could also use a mechanical oil pressure guage and check it that way to.

A 460 engine that acts like its not getting enough fuel. Will start but runs as if only on half the cylinders missing badly or such.


Check your running fuel pump pressure. If (as I suspect) it's too low, first try changing your fuel filter. After changing the filter, recheck the running fuel pump pressure. If still low, check you fuel pump pressure regulator. If OK, you may need a new fuel pump.

Also probably would be a good idea to replace you air filter.

Good luck!

1989 jeep wagoneer will not crank. Motor turns over and there is fire on the plugs. changed the fuel pump and filter. (Pump was bad) Fuel delivery is not right.


replace the crankshaft poisition sensor at the bell housing on drivers side, must be done from under the truck, very hard to see and even harder to replace, but that will be the problem..

89 Wagoneer drives rough


The thing to do now is a fuel pressure test pump could be weak just a few pounds under the recamended pressure will do that weather its mechanical or electrical . Is there a filter in the carb. wear fuel fine hooks? If none of this is an issue at least you can eliminate fuel deliverly as the problem.

1989 jeep grand wagoneer--no gas getting to carb.--


That may be right - no gas in the carb is likely a bad fuel pump, or a clogged fuel filter.
