My membership was just OK'd this morning, and right out of the gate, I have a question.
We have three Jeeps, a '90 YJ with a 2.5 that I ripped the engine management system off of, a 1987 XJ with a 4.0 that I am putting a 4.2 crank into, and our newest "little bundle of joy" a '95 YJ with a 2.5 engine.
My question concerns the '95 YJ. I am an "old School mechanic" who can listen to an engine run, and tell you if the carb is set up properly, but I don't know a THING about transistors, or the EFI's that they control.
We bought the '95 YJ with a 2.5 MPI on the first of the month from a buy here pay here lot, and once we got it out here in the quiet of the far west Texas countryside, I noticed that when I shut the engine down, the fuel injectors click for about a minute or so. I took a hunk of heater hose to verify where the sound is coming from, and it is coming from the electronic solenoids at the rear, (or top) of the injectors.
We live 90 miles away from the closest Jeep dealer in El Paso, and HWY 62-180 is a VERY lonely road, if the EFI quits half way there.
Can someone please tell me what is causing the injectors to click after the engine is shutoff? Is there an auto shutdown relay in the system? Can running it this way break the main computer?
