I just bought a NA fairlane 3.9ltr MPFI 6 cyl, unregistered, good body and such, was taken off the road cuz of a yellow sticker, have since installed new battery and everything is working...except the engine, the starter motor is fine, it's just not firing, it just keeps trying, I have checked the fuel pump, that is fine, I have also put on new spark plugs, and I have also checked to make sure they are sparking, but she still just wont start...my mechanic mate has come around to check all the obvious signs, he says he might need to check the pulse, but yeah, what do u guys think it should be?
