SOURCE: 1997 Jeep Grand Cherokee. Stalls out,engine quits running

since its a 1997 your jeep has EFI, electronic fuel injection. The most probable reason for your troubles would be the injectors or a problem with the computer controling them, not allowing enough gas to be pushed into the cylinder causing stalling or lack of power, also too much gas iin the cylinder can lead to back firing and stalling. This would also explain the reason it takes so long to start back up some times, all the excess gas in the cylinder is flooding the motor and u have to wait till the gas disipates till the engine will turn over.

I have a 1997 jeep grand Cherokee limited addition. that Stalls


Hi! I had the exact same problem with my jeep before. The wiring (located on the back wall on passanger side to the left) You will see three sets of plugs with a lot of wires on them. I had to get everyone replaced and the wires rewired and sautered together. My truck would backfire so bad it busted my muffler 3 times!! So, try that and I think it will solve the problem.

I have a 97 jeep cherokee that stalls and backfires and it has backfired to the point where it blew open my muffler. It doesn't backfire all the time, just at times...what can it be?


It's not possible to pinpoint, with just online info, what is causing the backfire, but if it blew your muffler open, the engine is definitely dumping raw fuel into the exhaust. Look into what can cause excessive fuel to be dumped into the exhaust and you may find the cause of your problem.

Stalls and backfires 1997 jeep grand cherokee limited replaced the map sensor, coil rotor. distributer, spark plugs, spark plugs wires. throttle body pressure sensor ,ingnition coil IAT sensor. amd still...


you need to check the fuel pressure,and did you mean you replaced the distributor or just the rotor because inside the distributor is a pickup plate that some times causes this also 02 sensor can cause this.is your check engine light on if so go to chain auto parts store they usually read your codes for free.

I have a 1997 jeep grand cherokee with automatic and 4.0 six cyl engine--it drives great for a day or two then stalls out seemingly for no reason--now tonight it has no spark from the coil--so I feel it is...


Unlikely that it's a computer. Check your coil and the grounds, make sure you don't have any breaks in the wires that could cause an intermittent problem.

Engine Back fired, blew out muffler.


Sounds like you may have gotten some debris in your exhaust pipe or something was clogging your muffler. Maybe the innerds of you Catalytic Coverter went and got stuck or the innerds of your muffler gave out. That would be the only few things I could think of to cause something like that.

Sincerely,

JC
