Electrical Guys Help - No Power to Fuel Pump, Could it be a bad coil? Options

[vesnyder]

Trying to figure out why my fuel pump is not getting any power and determined the power for the pump comes directly off the coil. The voltage leaving the relay panel is ~12V, but coming into the coil is only about 2-3V - that is with the wire disconnected - with it connected to the coil it is only ~.3V. Is this right? How do I determine if the coil is bad? How much for a new one?

Buy 2 relays. Throw one in the glove box, and swap one out with the fuel pump relay.

Now, remove the cover from the old pump relay, and put that in a lil baggie, in the glove box. This is your test relay.

With the cap removed, and the relay in place, you can acctuate it with your finger, press- wirrrr.... press- wirrrrr..... if the ignition doesn't acctuate the relay, but you can manually, it's the switch voltage not arriving at the relay..

I recently had THE EXACT same problem, that I chased for two years, not two full years... but over two ye.. nevermind!

Rebuilt relay board... gone.. gone, gone, gone.
