I'm reaching out to those Chrysler/Plymouth gurus out there for help. I'm almost done with this vehicle, despite replacing the head gasket and exhaust system recently. Here's what has happened -
1 - Started the car to leave the office, it stalled out and wouldn't restart. I have ample spark and fuel delivery.2 - So far I have replaced: plugs, wires, ignition coil, MAP sensor, ECM (power module located along driver-side fender wall behind the battery), fuel filter, distributor cap, rotor and ignition pickup (Hall Effect sensor).
3 - The car turns over fine, gets gas into the EFI throttle body (single fuel injector) and spark is ample on each plug/wire, it just won't "catch".I've checked the error codes via the ignition switch 'on-off-on-off-on' sequence, and all I get is '12 55'. If I'v read the Chilton's manual correctly, a code 12 is supposed to be "transaxle unlock relay", which for the life in me I have never heard of, unless they're referencing a neutral safety switch. If anyone can tell me if I've read the code incorrectly I'd sure like to know. I thought the code 12 was the opening sequence for any/all codes off the ignition switch method, but maybe I'm wrong?
I've just ordered a new Logic Module, and am waiting for it to arrive (today/tomorrow), so keeping my fingers crossed. If this doesn't work, I am at a loss to fix this car that up until now has been so good to us.
Does anyoe have any ideas what else may be the culprit here??
Thanks to all of you in advance!
