Are ALL the air intake hoses hooked up? NO vacuum leaks between mass air and throttle body?
yes the car will run when you prime it it has all the things it need to run
So to clarify.......you are spraying fuel THROUGH the mass air flow sensor?
no vac line for brakes
With ALL intake hoses hooked up and mass air flow meter plugged in .......can you scan to see if you are getting the proper reading? Any capability of live scan data would be very helpful for you.
