MAKE SURE DISTRIBUTOR COIL IS GETTING POWER.IF NOT.CHECK IGNITION FUSE.IF FUSE IS GOOD AND COIL IS GETTING POWER.REMOVE COIL AND CHECK THE COIL PRIMARY RESISTANCE USING A DIGITAL VOLTMETER. IT SHOULD BE 0.1 OHM.SECONDARY RESISTANCE SHOULD BE 5000 TO 25000 OHMS..IF COIL PASS ITS THE IGNITION MODULE.IF COIL FAILS.COIL IS BAD.

Truck wont start


If you have no fuel pressure at the engine when key is on, the pump is not coming on. Check fuel pump fuse, check fuel pump relay (relay should click when key turned to on-put finger lightly on it and feel for click when someone turns key to on). If no click, signal from computer may be lost, ground for relay may be lost, or relay may be bad. If it clicks, wiring from relay to pump may have failed, or the relay's main power source may not be there at relay-find the fuse link or maxi-fuse that powers that relay. One terminal at relay should be hot at all times-can check for that with a test light.
If pump is working and you do have fuel pressure, you will need to check injector circuit. Post back if questions, or need further help.

Do you hear the fuel pump running on the prime cycle (when you turn on the key) (runs for 3 seconds) or when you have oil pressure?Have someone listen back by the tank for the wrrrrr.If you do have to change the fuel pump,make your life easy and just tilt up (lift) the pickup box from the drivers side to access the fuel pump.Takes 20 minutes to change it that way.

2005 ranger 3.0 truck starts pump runs presser good pump stops no presser after a few minnits


If you are talking about the fuel pump, you have only a few cheap fixes before blaming the expensive fuel pump. The fuel pump relay can overheat and kick out. A new relay could fix this. Autozone.com offers free fusebox layouts and wiring diagrams just for registering your truck with them for free.

Sometimes the horn relay will interchange with other relays. Look at the part numbers and use the horn to test the fuel pump relay. Or switch the 2 relays.

A fuel filter could be clogged and overloading the fuel pump. Put in a new filter.

After that, its a case of testing the fuelpump leads and see if the fuelpump is shut down.

I hope my solution helps.

Won't start


Well lxmccarthy, since you put a new fuel pump in, check a hose after the pump and see if any gas is being delivered. You can also try some starting fluid in the carb to get something going. There probably is just some air in the fuel line.

Truck wont start has lots of spark and getting fuel but wont star


Fuel pump fuse, relay, or actual fuel pump, can you hear it run when you turn the switch to run if so then check your fuel filter.
Hope this helps!
