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



You need to pull the washer bottle bucket down by the left, front 
wheel and check the plug in the wiring harness. The fuel pump power 
goes through it and if it has a bad connection you won't have power 
or ground for the pump. You also have to check the fuse and the 
connectors in the fuse block for overheating damage. Finally you 
need to check the inertia switch. The ground for the fuel pump goes 
through it. It could be bad, the connector could be burnt, or you 
may not have the newer switch. If the inertia switch does NOT have a 
white paint splotch you need to replace it as per the recall. It is 
also supposed to be relocated to the side of the footwell, not on 
the Lamba counter. When you have bad connections in a circuit it 
drops the voltage in the circuit causing the load to draw more amps. 
The additional amperage casues more heat to be created increasing 
the resistance which increases the current. Bottom line, a bad 
connection in a circuit will cause ALL of the connections in that 
circuit to overheat.
