Ignition problem

[PKRWUD]

I need for you to test the TPS first. Backprobe the connector at the TPS, not at the ECM. See, there is a very real possibility that you have a short to ground in your vref circuit. This can cause many, many problems, with several symptoms, including sending the ECM into clear flood mode. This may or may not be the problem, but the way I work, I rule out things in a set pattern. That way I'm not jumping all over the place. It's a b*tch doing diagnostics online, and i've given myself far too many headaches over the past 4+ years by not following a pattern, like I do in the real world. Besides, you're going to have to have a DMM before we can go on, anyway.



I agree with Fritz in that Fluke is the best bang for the buck. I've got at least a dozen DMM's, including a 25 year old Fluke benchtop DMM (with tubes!), but my favorite is my 88. It came in a nice little case with a very handy inductive pick-up for measuring rpms without having to disconnect anything...
