Your engine is not a Magnum model, but I don't think the operating principle (or, computer controls, perhaps) is much differant. Use this if your engine is fuel injected, otherwise, to tell you the truth, I've never delt with a carberated engine.
When you turn the key to the "ON" position (not "START") you should hear the fuel pump turn on for a few seconds. You can also disconnect a fuel line (relieve fuel line pressure first) and turn on for a few seconds with line directed twords bucket (do NOT disconnect the rubber hose connecting the two fuel rails, as per what the manual says), OR you can attach a fuel pressure guage to the fuel rail.
Test the fuel pump relay (link below)
If fuel pump does not show to be working, remember to check for voltage AT the pump before going and buying a new one. (On the 1996 Dakota, the dark green/black wire comes from the fuel pump relay, and the black/white and black [thats two wires] are the grounds.)
Use the following link: here
. Look at my post (post #2) to test some stuff (as far as spark is concerned). NOTE: The test shown for the Automatic Shutdown Relay will work for the Fuel Pump relay as well (but only for those two)
I hope this applies to your truck. Let us know what happens.
If parts ain't flyin', you ain't tryin'.
