van suddenly died and would not start. This van has a lot of miles,
160K, and recently was run with oil very low (2 qts, few weeks). I thought that the timing chain broke but looking at the valves they seam to be moving fine. This happened one day after replacing bad compressor and tensioner that were making a lot of racket. We put about 50 miles on the van and everything was running great and then it died while on the interstate. We heard a little thunk as it died but nothing very loud.After testing, I found that it did not have any spark. I checked the coil and found that it tested good. I checked to make sure there was power to coil and I have not been able to detect anything (using light buld circuit tester). I have no error codes when using the key method except usual 12 & 55. I decided the cam or crank sensor might have went. I replaced both and still no power to coil. Tested both and fuel pump relay and ASD and both appear to be fine. The fuel pump clicks on and develops pressure when the key is turned on. If I unplug the cam and crank I immediatly get error codes 11 & 54.
I think I am down to the PCM but wanted to get someone's opinion on this. Will power still be deliverd to the coil if the timing chain has slipped? Also, is there anyway to test PCM with out having a computer? What else will cause the PCM to shutdown power to coil?
Thank you,
