[DML] Re: Fuel Pump Not Getting Voltage After RPM Relay Replaced



David - please !!!!!!

a higher resistance means less current !!

Mr Ohm invented this basic law: R = U / I !!!

@ Jim - no it is not the coil. The coil is driven 
by the ignition ECU as is the rpm-relay.
Did you bridge the rpm-relay to let the fuel pump 
run continuously ?
the rpm-relays tend to fail because of a loosened 
solder joint. this may behave like you described - 
somtimes it works, sometimes it won't.

checked the inertia switch ?

do you have a schematic of the car ?
