could be crank sensor:|:|looking for a engine control moduel from a running 2005 (automatic). I ordered one from a online supplier and had it programed to my vin but the engine will not start (no spark). I think any 6.0l engine ssr moduel will work- my part #12595928. Jan
the code scanner listed a serial buss communication problem and I sent it in for repair; they claimed it was unrepairable due to a buss short. I bought a new engine controller with vinprograming. Using a inline spark indicator no spark is noted and after cranking a plug is not wet indicating the injectors are not working. Voltage is present at fuse 29 and 36 and the fuzes were tested ok and replaced with the same results. The only problem found was a blown fuze 23 which prevented cranking. There are no new codes on the code scanner. This is why I would like to get a known good engine controller to see if the programing is correct. JanI am not sure what/who diagnosed your problem as bad ECM, not common!
Crank no start can be caused by many problems --
I apologize in advance if this has been checked - or power to ignition coils has been confirmed.
check fuses 29 and 36 of underhood fuse box (these supply power to ignition coils on each side of engine) for 12 volts on both sides of fuse with key in on position. (DO NOT CHECK BY LOOKING AT FUSE - USE test equipment)
If no voltage on either side of fuse -- possible failure of relay 42 or fuse box problem
CKP is located near the starter -- three wire sensor -- easily tested with proper scan tool!I have disassembled the fuze box and high current tested all wires as well as replacing the ignition switch. The car was wrecked where the transmission controller cover was torn off which is next to the ECM. I thought it reasonable that the ECM received enough of a shock to damage it. It has been a while so I don't remember the error code and my reader doesn't id the moduel or display cranking rpm. I will check the crank sensor if I can figure out where it is. Jan
Do you have an ECM for a 2005? I couldn't tell if you were also looking to buy one, or had one for sale. I nned a part # 192 10 071 for my 2005.Engine Control Module from the Parts Manual:
