Why does a 2003 Jeep Grand Cherokee turn off when you put it in reverse?

Answer 1

You might need to replace your PCM (Powertrain Control Module)

Especially if your Jeep spudders, shuts off and tries to gas itself when your pressing the brake. That is what happened to my Jeep and a new PCM fixed it.

I hope this helps you

Answer 2

If the engine dies when you shift to reverse (or any gear), then it could be low on Transmission Fluid. If this is the case, do not drive it or you could destroy your transmission, which is a very expensive repair. Get the transmission fluid problem (possibly leaking seals) fixed instead.

Answer 3

my '97 had a short in the fuel pump in the tank. It would hiccup when I took a left turn. Had to drop the tank and replace the pump. Well, the goodyear dealer did it.

Answer 4

If this is happening without you removing the key first, then check the PCM=computer. The issue is most likely there.

Answer 5

Crank Position Sensor needs to be replaced. I had the same problem and that was the cure. It was hard to diagnose because of the intermittent nature of the problem.
