m50b26 won't fire but turns over (ms2)

Post by litty »

Can someone check .msq what i am missing? I am getting RPM signal, spark and gas, i am guessing its probably something with spark timing?! Engine is almost stock
I am kinda new to this (tune, ms...) :RTFM: , i want to at least start the engine, before i go to the tuner...

Thanks you!

You are guessing it is spark timing? Use a timing light to check timing for sure, on every cylinder if there is a problem when you try to start it. Use a simple (non dial-back) light, they seem to offer more reliable results.

Did you check the spark timing, on all cylinders? Is that MSQ posted still current? Have you tried disabling the fuel pump/injectors and using starting-fluid to confirm this is *just* a fueling problem? Post the MSL of a starting attempt.
