cold start up

[W8S SS]

after my truck sits a few hours, it takes a few seconds to start up. it just turns and turns and then fires. is there a common problem rangers that they do this?

Try turning the key to ON (do not crank) then Off, repeat 3X.

If that helps, the checkvalve in your fuel pump is bad.


Pasted from the 2000 Ford CD:

Fuel Tank and Lines

The mechanical, returnless fuel system (MRFS) consists of:

l the fuel tank (9002)

l the fuel tank filler pipe (9034) which contains a restrictor plate to permit only an unleaded fuel nozzle to be inserted

l a 1/8 turn fuel tank filler cap (9030)

l a fuel filter (9155) providing filtration to protect the fuel injectors

l fuel line

l a fuel pump and sender assembly (9H307) containing:

— the electric fuel pump which provides pressurized fuel to the engine

— the fuel level sensor (9A299)

— a check valve to maintain system pressure after the pump is shut off

— a pressure relief valve in the electric fuel pump for overpressure protection in the event of restricted fuel flow

— the fuel pressure regulator
