Ignition switch ? Thermostat? Something you did wrong after the rebuild. Crankshatf position sensor? the wiring on top of the tranny not connected?

The tranny wiring ig odd and connected. The CPS is a little grooved i noticed yesterday. Thermostat is good, but going to change it when i install my electric fan.

I am just tempted to take it to the stealership and have them run a diagnostic on it. And see wht they tell me and how many fingers and toes they will charge me.

Emissions are hard to find unless you got a manual. I got "Automotive Technology a systems approach" from my college course. I also got the factory manual from Jeep . They both cost me $100.00 each but are well worth the money.

Is it possible to connect it to an OBD I scanner? I have a friend who has one. I did get under and looked at the CPs. It is grooved on the sensor end and has like a piece missing from the side. I also noticed that the screws that hold it in place are different. It looks like the transmission people only put it on with one screw and then it messed up and they found another screw to fit in there.

i read this on another website:
Symptoms of a CPS problem:
- Poor starting.  The engine cranks longer than usual
  before starting.
- Vehicle stalls for no apparent reason.  Hot, cold, idling,
  accelerating, or cruising, etc.
- Vehicle starts and stalls after 10 seconds.
- Vehicle won't start.
- Disconnecting the battery or CPS connection and reconnecting
  it seems to solve the problem temporarily.
- Engine diagnostic codes may indicate fault 13, 14, or 15.

OBD 1 ended in 1995 I think. OBD 2 started with 1996 model year vehicles if I am correct,it's got different pig tail adapters for each brand of car I think(ford,chevy,dodge etc..). Yeah, I mean you just got to go through eveything they did to your car , prior to messing with the other stuff they did not touch. A good muffler shop will tell you if the cat  is in backwards or not.Anything that looks supect could be the culprit. I always double check any mechanics work. They mess up just like we all do.  I have heard of stories where a mechanic emptied the tranny oil, and overfilled the motor oil, then blew the hell out of the car on a test drive.
