HI , I got a '85 ranger it came with a replacement engine from a newer mustang(exact year unknown) I had to change a few things mounts/fuel rail nothing major.When I first tried to start it the gas pump was no longer coming on , so I ran a wire to the pump from a + source and it worked. yet still didn't start and there was preasure on the rail.I sprayed stater spray in the chamber an d it starts for a sec or 2. I removed the sparkplugs and they were dry.
I am really confused and don't know what to check next..
I was told that I may have to change the fuel pump due to a lower preasure.
Is this possible?
why won't my pump start anymore(i drove the truck in)

after being told the pump may have low preasure for the engine I put the injectors from the original engine thinking if the pump was good enough before this should work..sparkplugs are still dry although there is preasure on the fuelrail
All tests were done with fuelpump hooked direct and it does not shut off.

Any suggestions please
 
You'll burn through that pump real quick. Your gonna have to find a source thats got juice to prime the pump with the key in acc., and then just run the pump normally. Have you checked the fuel filter? You can have fuel pressure, but that does not mean you have volume..
 
Check your relays on the fenderwell
 
test to see if your injectors are noiding if not its most likely a bed relay or computer has a bad ground or the computer is toast
 
Are you trying to run a fuel injected engine with a fuel pump for a carb'ed ranger (I'm pretty sure 85 2.3's were carb'ed)? If so that's not going to work. You need to get the complete fuel system (tank, pump, lines) from a fuel injected 2.3 ranger. I'd recommend an 89+ with a plastic tank and single, in-tank return style fuel system.
