Megasquirt1v3 No cold start issue + other issues

[SiGmA_X]

Hey guys. I am running a MS v3 with extra code 29y5, and had it running twice for a couple days, the last time for just one day, and now it doesn't run.

I am having unusual signal reports, eg 120kpa while cranking, 1700rpm when the engine for sure was not at 1700rpm, etc. What should I check?

Here's a log picture,

Tomorrow I will be checking to see if I have spark on all 6, I know I have fuel due to the fouling of the plugs.

Any input would be awesome!

aw what the hell man, i thought we had that thing running :-P

i got no idea on that, bizzare, especially because i know the car used to run.. otherwise i'd suggest checking power and grounds... the 120kpa part really throws me off, because my map signal has always been clean even when everything else was falling apart.

hmm, 029y5.... i had problems with 029y4, the car just would NOT fun properly with all the exact same settings... i flashed back to 029q and everything is "perfect" again. and by perfect i mean driveable, i still have that goddamn "rev limit" that we were talking about when i was still out in OR. IIRC, you were running 029y4 when i was out there, so maybe y5 is screwing you up somehow?

Humm thats an interesting idea on the versions being the problem, maybe I should change to high-res code all around and give it a go.

Tomorrow I'm going to be removing plugs and checking for spark at all plugs.

The MAP, I'm worried that is because I got water in it. I have a replacement on the way, but it won't be here for a few days. ColdFusion21 offered his for testing, but if thats not it, it could be a pain to put it back on his board.

Since you saw the car, I have installed all new wiring inside the case. Its far, far cleaner now, and has ran since the wiring was changed. I wish someone could lend advice as to what to use for starting settings, but people don't seem to like to do that with M50 files!!

So, it has spark on each coil. I can smell the fuel, and see it on the spark plugs. But it still does not start. Tomorrow I'm going to test how strong the spark is using a spark tester, and do a compression test. Any advice?
