Default Won't connect to TS once on the car...

I can no longer get TS to connect to the MS when on the car. It was working last night, and now nothing.

-- standalone harness
-- works when on the Jimstim just not on the car
-- worked last night and then nothing all day
-- car works fine back on the stock ecu

The part that is getting me is last night I could connect fine, but this morning nothing. I searched and didn't find much, anyone run into this?

Thanks

Does the MegaSquirt have a solid 12V source? Don't assume. Test.

That is what I am about to test. I know the D14-16 are dim and I just did a volt test on 5v. When on the car it only 1.5V and when on the Stim its 5V. So seems to be the right path.

Sounds like a short somewhere.
If you're running a 1.6 manual TPS, unplug it.

Forgot about that one. I'll do that also. Currently check my harness since the board seems fine and the car runs on the stock ecu. Making me think my harness maybe bad or there is a short

Total fail on my part.

Unhooked the TPS and got full power. Still not sure why it worked yesterday but either way. I finally got a datalog, during cranking. Now to see if I can figure out why not starting. (most likely still no spark).
