no start, need help
I have a 1990 f150 5.0 4x4. I hae replaced the fuel pump, dizy and plugs. The truck did not start when I bought it. It will turn over with starter fluid in the TB. Once that is gone it cuts out. I just recently got my hands on a gauge to tell what the fuel pressure is at the rail. I know that fuel is getting to the rail but I am going to check that it is the right pressure tonight. My question is, if the fuel pressure is right and it holds pressure what else is could I be missing. The only other thing that I can think is that maybe a injector is stuck open.

You need air, fuel and spark. One of those is not getting where it needs to. For giggles, look on the driverside firewall in the cab and make sure the inertia switch hasn't been tripped. If it hasn't, make sure you're getting fuel at the rail. If you're still not....I'd be swapping the fuel pump relay.

So I checked the fuel pressure tonight. I am getting about 10 psi when I turn the key to just before run. When I crank the motor over the fuel pressure comes up to 37 psi. The motor just cranks and cranks. It will kick over if I spray starter fluid in it. When I stop cranking it over the fuel pressure does stay up and continued to stay up for as long as I was out there (15 min or so). So what next, I am lost.

No it does not try and kick over with the gas pedal to the floor. I have checked a couple of the injector connectors with a noid light and I am getting the pwer signal to them. It is like I am not getting any fuel in the clynders.

no the truck will not run at all. The only way that I can keep it running is if I continously spray starter fluid in the throttle body. once that fluid is gone she dies.
