Question about 1988 Jeep Cherokee
I have a 1988 Jeep Cherokee 4.0. Motor replaced three years ago, but I have had this problem the whole time. It sometimes cranks and sometimes doesn't. If it wont crank, I can sometimes crank it with a little ether, other times it won't crank at all. I took it to the dealer a while back, and was told to replace the throttle position sensor. didn't work. injectors are good, always have fuel coming through, spark is good, coil is good. Tried cleaning out the throttle body intake really good. I have no clue what else to do. It will turn over but will not crank every time. It also can turn off if I slow down to turn or stop.
Did you have the same cranking with no start problem with original engine or did the problem begin when you changed it? I would check codes if you have not already, and would also clean business end of idle air valve (next to tps) DO NOT turn the end plunger while cleaning or it may not seat properly. Do not loose the rubber "o" ring while working either!
