my 280zx datsun will not start fuel pump has preasure cleaned out my fuel system its not spark i have spark idk whats wrong

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.

ok

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.

Check your fusible links and relays.

I'm having the same problem, getting fuel and spark but won't start, an won't start with starting fluid either but mine has 42,000 miles on it
