I just took the MSM out of winter storage today. I went start it an no-go. I changed the plugs, checked the spark (all 4 were sparking). I can get it to catch for a few seconds if I press the pedal to the floor. After it semi running on a couple of cylinders I checked the exhaust ports. 2&4 were hot, 1&3 were cool to the touch. I'm guessing they are not getting fuel. I unplugged the Cam sensor and it would not catch at all so that seems like its working. I can hear the fuel pump running and once it catches I can rev it up to 2-3000 RPM. It stalls the moment I release the pedal. Attached is a log of the MS3.

Any help is appreciated.

 

Keep guessing, let us know what happens

 

I sure will. Thanks for the input

 

What curly is trying to say is without logs of it trying to start and failing, there is not much we can help with.

 

Log is attached to the first post. I looked at everything I could without pulling the fuel rail. Everything looks good. It was running fine when it got parked for the winter.

 

Ahh, when I first looked I thought you posted a .msq not a log, my bad on that.

 

what's the MAP signal looking like?

 

Well it's now working..... Weirdest thing, I couldn't find anything wrong. What ended up working was to physically unplug the wiring harness from the MS3 and then reconnecting the harness. All connections were tight and normal, but as soon as I unplugged/replugged everything worked fine.
