Security system problem?

[cafedan]

Does anyone know how to disable (or over-ride) the security system on a 1999 Grand Cherokee? The engine turns over but just won't start. I have ruled out the fuel pump and I'm now suspecting it's the security system. Any suggestions will be very much appreciated.

I had to override the system on my '95 XJ, I locked the drivers side door manually inside, shut the door, then unlocked it with the key. hope this helps you.

There are some good write ups on Jeep forum about this. There are differences in years. our 98 GC Limited 5.9 uses a remote that has to be programed with a computer. The earlier GC you could program them with the key. As for the WJ I have no idea. Remotes & security systems seem to go together.
You might do a search here. There are some great write ups on several things here. either way you will have to search.

Sounds more like the crank positioning sensor then a security issue.
