I've been troubleshooting some tranny problems and decided to unhook the batteries to reset the ECM. Reconnected the batts, now the thing won't even engage stater. It had done the nostart thing before, but would always restart eventually after siting for awhile.
So does the starter spin? or the engine turns over just won't start? Double check your connections at the battery since that all you working one after it wouldn't start. Might have a loose clamp or poor connection
Sounds like a neutral/ park safety switch I am guessing it is an auto, try moving the shifter lever around try and crank in neutral and that kind of stuff.
Yes it is an auto, is the neutral/park safety swithch the same as the MLPS on the driver's side of the tranny? I kind of suspect that thing anyway, while trouble shooting tranny problems I had taken the electrical connector apart and it seemed a little dirty inside. I'm considering replacing that part anyway based on what I have read in previous posts. is there a way I can tell if I have the original MLPS? there is about 265K miles on the truck
well I took the MLPS connector apart and inspected both halves, quie a bit of dirt in each. blew them out with compressed air, reconnected and it started right up.
I'm still considering replacing the MLPS and connector, it sounds like there is a an improved design the stays cleaner in the connector?
