Anoth Fuel Pump Question

[twinturbo]

The inertia switch is in case of a crash where the engine remains running. On the eec-iv if the engine stops the ecu kills the pump relay, on some cars there is an external RPM sensing ( tachimetric ) relay that needs a ignition pulse or it cuts the fuel pump.


I am not sure what the IVA manual states.

Your probably not going to over fuel so long as you have a preasure regulator and return.


Remember also that the pump ( certainly injection ones ) draw quite a few amps, and if left running on a stoped engine will drain the battery.
