I installed an M42 in my car yesterday, and got it all set up to run today. However, I cannot get it to start. The engine has been sitting for about 2 years. It sounds like it fires on all cylinders once, then just pops and splutters. This happens every time I turn the key, each cylinder seems to fire once, then nothing.
The fuel pump is working and I have pressure. The firing order is correct. Everthing seems to be connected correctly.
Does anyone have any clue what's going on?
