Thers only one problem with replacing a computer on a newer model vehicle and that is when you get a computer sometimes you have to "flash" the computer to put in your vin numkber and other things. If you don't your vehicle won't start or it will start and immediately die. The only place I know of that can flash computers in the dealer. A computer for your vehicle is about $900 from the dealer and then you have to pay to have it flashed. Hope this helps.

Where is the ECM located?


ECM is probably OK. On this year its one of 3 things. First its the ignition coil causing the problem. This is the most likely cause. Second would be the fuel pump is going bad and partially locked up. The third reason is the crank sensor is going bad. Jeep ECMs don't usually act like this, they just stop working and don't act up intermittently. Not saying it couldn't be faulty, just unlikely.

The FSM (a book by that name from Jeep, by year,model)

Jeep 1996 Grand Cherokee v8 no power to coil


no battery voltage or no signal from ecm to trigger the coil. no battery voltage is simple as running a wire to the coil from the battery to see if vehicle starts. if it does then make sure you don't drop voltage as the vehicle is in start position. could be a bad ignition switch.

I have a 93 jeep grand cherokee. it will only start when the check engine light comes on. i have replaced the ecm. still not fixed. any suggestions?


Did you replace it with a re-manufactured or used ecm? If used, not all ecms are compatible with every vehicle. It has to be the exact same numbers on the ecm, matching the one in your jeep.

Hi can u help me plz my 1994 jeep grand cherokee laredo 4.0L Automatic have problem with it before I start my jeep, i have to let it sit with the key in the "on" position for 5-10 min may be more...


Your ecm is going bad. If you haven't noticed yet, the vehicle will only start once the check engine light comes on, on the dash. That's the ecm finally sending power to the relays that feed the fuel pump and ignition systems. If you're mechanically and electrically handy you can remove the ecm, disassemble it and replace the three power capacitors inside. If not, just have the ecm checked and replaced.

1994 Grand Cherokee, 5.2 V8 shuts off when hot. Cool for an hour or 2, starts up ok for a half hour or so, then dies again. No trouble codes except 12 and 55; I pulled fuses to check them, hence the code...


Your engine computer is bad. It's a good thing that you mentioned about the check engine light dying also, as this is a classic sign of a bad ecm. I have repaired more than one of these Jeep computers, replacing the three power capacitors located inside the computer, and they have worked for years afterwards. If you don't have the skills or knowledge to repair the ecm, get yourself a rebuilt ecm unit and swap it out.

My 1996 jeep cherokee sports is turning over but not starting. No voltage to input side of coil. ASD relay seems fine, crankshaft position sensor??


The CPS is one of the first places to start, but remember that the signal goes thru the ECM first, which ultimately supplies power to the coil, I've had to replace the ECM on my 96 Grand Cherokee 4.0 3 times. The dealer wanted to replace the crack and cam sensors, but it was only the computer that was bad.  Sorry I cant give you any definitive answers but I did get it to turn over when I hit the computer with a wrench!
