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?

QUOTE(vesnyder @ Oct 3 2005, 01:59 PM) Will hopefully do some more checking to ensure it is the fuse/relay at the panel? on a stock D-Jet, the pump will run for 2 or 3 seconds when you turn on the key to build up pressure, then shut off. no need to crank the motor. the FI-brain controls the power to the fuelpump, so no power to the pump can mean a lot of things. if you get power to the pump relay, check and see if the brain is grounding out the pump relay correctly. if not, check your engine harness and see if all ground wires for the brain are attached and make good contact (white wires) if all that checks out OK, try a loaner brain (they rarely fail, so suspect other problems first) ...
