2003 with 5.4 engine with current mileage of 226,225 - Vehicle shutdown and had to be towed home. Replaced oil pressure switch along with new oil and filter (previous oil change less than a week prior with only 300 miles on the new oil change). Vehicle cranking power strong with no grinding noises - sounds good but just won't catch. Light comes on when trying to start. Disconnected and then re-connected battery to see if would clear but light came back on when trying to start. Tried to locate oil temp sensor on front right side of engine (2 wire connector -red/gray & yellow /light blue but don't have a photo of sensor / location. Not sure if this would help.
Currently, I don't have a scan tool available so I don't know if it is providing a code to trace.
8 weeks previous to this incident, vehicle started to constantly display of alternator light and message center displayed charging system message which when cleared, would come back in 10 minutes. Local shop diagnosed that charging system working fine but could not get the replacement wiring harness (obsoleted) per the associated Ford tech bulletin nor could they verify that the PCM which also was mentioned in the bulletin was ok (no sticker on PCM to indicate date / tune code - vehicle date of mfg. is Nov 2002). I had been driving the vehicle without incident ever since.
Trying to see if I can get it running again but so far not doing very well. I would appreciate your insights. Thanks.
