Remote starter messing with PCM? Sign In

1996 Jeep Cherokee 4.0 55k. I tried to install a remote starter today. It didnt initialize properly but it managed to start my car one time. The next 4-5 times it cranked the motor but the car didnt start. I tried to start the car with the key and it just kept turning over but no start. I disconected the remote starter checked the connections and tried again. No start just cranking. I tried to start it while hitting the gas it started but it wouldn't hold an idle. I started the car in neutral and drove it around the block and it idled fine after that but then after I shut it off it gave me trouble starting without me hitting the gas. Sometimes when I start it it catches and idles fine and others it doesn't catch or just instantly idles out. The fuses beween the remote starter module and the rest of the car are not blown. The module stopped responding to the keyfob also. The only problem I care about right now is my car not starting. Any help or ideas would be great thanks.

It's possible you might have something else going on.....Pull the codes to see if you set anything....

It might be a PITA but remove the system completely and get it running right.......Then sit down and go over the instructions & wiring diagrams very carefully to make sure the install didn't go south....... Everyone is different but at least a 6 pack before I start usually works out good for me......Wink

One thing you may try before doing of this is see if there is a tech help number for the system.....This might be a common problem with this system and older JTEC PCMs. Hopefully a quick call will take care of it for you....................

Thanks for the reply. Thankfully the problem was quite simple. Being that the engine would catch when I had my foot on the gas I figured that something might be wrong on the air intake. When I rented a vacuum pump to test the Map sensor it was pointed out to me that a bad sensor would throw a code and my CE wasnt on (96 jeep is OBD2). I cleaned out the air intake with carb cleaner careful not to get any on the iac, map and whatever the 3rd one there is, and the car hasn't given me a problem since. As for the remote starter when I reset the module it started working properly. 2 different problems at the same time 2 easy solutions
