The TPS failed every one except the wide open test. All the other test were low or didn't read at all. The MAF came off the runner and stored in the back of it the whole time. Then was put back on, no cleaning or messed with, just on and off. It failed all the test except for closed and open on terminals 1 & 2 if I recall. Sorry I'm not much help, I just don't remember all the details.

If I replace my TPS and jump the two brass terminals on the MAF connection and the truck starts, GREAT!! If then I plug the MAF back in and the truck won't start I know I will have to replace the MAF too. Either way I currently have the Brass terminals jumped and still no luck, so something else is causing it not to start.

Everyone keeps telling me it sounds like a timming issue, then you tell me that the TPS conntrols some of the timming. So it would make logical since for me to replace the TPS first, plus it is less costly!

Any recomendation on where to get a TPS? I need to know so I can go get one.
