the picture you posted was a 94-97 MAF connector, not a 90-93 AFM connector...
that was reading fine, and wasn't the issue. it's all in fuel tuning right now.
do what i said, half the req_fuel value in there right now and just see what happens.
and again: is this a DIYPNP or a MSPNP2?

I just don't understand what could be going wrong here if the stock ecu has the ability to fire right up and idle but the megasquirt can't do that with all the settings set correctly from DIY auto tune.... Something here is wrong..... I'll go over my timing again! Then I'll pull and test each wire for spark using test mode... And I'll do the same with injectors..... And if all is good then in out of ideas here guys...

We put the engine in time last time and didnt turn it over a few times to make sure the slack didnt change the engine timing.... We just assumed it was right.... it was off a tooth when we just checked. With that said is this where It has to be at this bottom pulley? WITH EVERYTHING LINED UP IN THE TRIANGLE UPSTAIRS and downstairs....
