This is for my 1980 Cutlass Calais, but I'm using all GN parts, and 1980 was THE LAST year the Cutlass had no ECM, so I don't have one.
In an effort to install, AND wire up my new In-tank Fuel pump ( GN tank, Walbro340, Racetronix Harness) I have run into a problem.
There is supposed to be a fuel pump switch connected to a Oil Pressure switch; no pressure = no power.
There is also a wire that is supposed to go to the ECM to trigger the pump to 'pressurize' the lines for a few seconds then shut off for ease of start-up, and so that the pump doesn't run-on while the key is in the ON position, but the engine isn't running.
How would I/should I wire this up so that I have some type of fail-safe system WITHOUT an ECM, or Oil Pressure switch?
If I have to install a Oil Pressure Switch, where ELSE besides the Factory location can it go? I have thought of 'hiding' it with a S/S braided line that runs across the intake, and having BOTH the Oil Pressure Sensor (for my Gauge) and the Switch (for the pump) somewhere in the engine compartment. Anything is possible I suppose.
