Timing possibly, how many miles on this?

350,000 but you would squirt gas in the intake and it would fire for a min

and the guy i bought it from drove it everyday until the brakes went out and he got a truck and just parked the car it sat up for two years


Ok then, you have a fuel issue. Would need to check fuel pressure, and do a bleed down test to see if it is the fuel pump, or leaking injectors, spider lines or regulator. Putting fuel in the intake and it firing up is a good indication for a fuel issue.

ok ill do that


could it have anything to do with the injector not firing


Well ya, there needs to be voltage to the injector. I think it's like 5 to 7 DCV. But if you do a fuel bleed down test and the pressure gauge drops, then there is a leak. I haven't looked up what your fuel pressure should be but I'm thinking like 9 to 14 lbs.


hey will my car run with out the mass air flow sincere


No, will not.



Hey I have a 79" 280zx it's getting fire and gas but not starting? ?


Bobcat90, if you are getting proper fuel delivery, and have spark, then there is a timing issue to look at. I would need to know the size engine to see if there is a timing belt on it, and if it is an interference engine or not.
