1987 Jeep Wagoneer Limited Fuel Injected Inline Six Cylinder

Check fuel pressure with the appropriate fuel pressure guage, available at any auto parts store.

Check exhaust backpressure.

I did not make it to the parts store, working twelve hours. I will see if they are open Sunday though. I went out and started my Wagon and it started with a little coaxing. I did notice that the second injector in was leaking gas. Going to get a o-ring kit. I turned the injector a little and the engine reacted by staying running. It idles pretty good, but sounds as if it is missing? I put on those new parts but as I see they did not help much. I tried to drive it but as soon as the transmission put a load on the motor---the motor seemed to lose its power and want to cut out and die. I feel pretty ignorant that I can not pinpoint the exact problem. I do not mind putting on a new fuel pump, but I would like to be sure that is the problem. What will the exhaust backpressure tell me? I do appreciate your help and input----THANK YOU!!!!

You don't just put on a new fuel pump without checking fuel pressure with the appropriate test guage.

If exhaust backpressure is high the cat is plugged. Generally you have an exhaust place test this.

Thank You. You are right, I sure would not spend a $100.00 on a new pump if I do not have too. I am curious to see what the pressure is. It is nice of you to help me out and guide me in the right direction. I do very much appreciate it.
