Question about 1999 Chrysler LHS
My car stopped in the middle of the street. I took it to the repair shop and I believe it could be the ECM? Only because I had a dianostic a month ago and that was one problem that came up. How do I replace the ECM myself and where is it located in my car?
It should be on the drivers side firewall, are you sure you don't have a loose connection somewhere? Reason I'm asking is that ECM'S rarely go bad and if they do they don't just start working again.

It should be something you can do yourself. Most pcm's are located on the inner fender with two or four screws holding them on and two to four wire harness plugs going into them. The ECM is not the first place I would look for any problems.PCM failure is very rare.Much better chance of input power problems rather than the actual ECM itself.

Did the new ECM come from the dealer or a junk-yard?
I ask because if it came from the dealer it would need the prom installed and it also may need additional programming and/or updates. But do recheck your connections. You may have accidentally bent a pin or broke a wire.
