Trying to stop the shotgun approach of fixing my starting problem (Already installed a new fuel pump, needed anyway though), I decided to check my codes as per the instructions on gojeep.rockrawler.com. I pulled a 12, 22, 55.
The 55 is the end sequence, the 22 is when I disconnected the battery, and the 12 is supposed to be a faulty coolant sensor, or short in the line.
I was expecting an 11, for a bad CPS. I ran to the engine bay, disconnected the CPS connection, the MAP connection, and dis/reconnected the coolant sensor on the thermostat housing. I ran for codes again and pulled another 12,22,55.
No codes pulled for the disconnected CPS or MAP sensor.
What gives? Am I just reading diagnostic problems from when before the jeep died, or is the check engine light diagnosis real time?
Just some backround:
Jeep died on interstate after 1/2 tank fresh gas
turns over fine
all relevant relays recently replaced
new optima
replaced suspect fuel pump
ALL electrical connections disconnected, inspected, greased w/dielectric
Was going to replce CPS , but codes check out ok. Any suggestions?
