I dont know When I look at the schematic the computer provides ground for the relay so the yellow wire is hot from battery the or/ltblugoes to your pumps red is power from eec relay and tan/ltgrn is th ground from the computer to the solenoid> There is a low pressure fuel pump in the tank and I am not sure where the high pressurre pump just trace the fuel line unplug all and test for shorts the inertia switch could be wet or a wire worn thru my book dont say anything about it that i could find if it is not shorted dont worry the pump in the tank has 4 wires 2 for the guage and two for the pump but looks like they use the same ground. I suppose you could check the relay pull it and see if the coil is still good check for resistance between the big connectors should be closed circiuit close to 0 ohms also there is a fusible link between the battery and relay on the yellow wire so if your getting power there it is not shorted. pull the relay and turn the ignition on there should be power to the red wire. You will probably have to disconnect the computer to check for shorts as the or/ltblu wire goes to both the computer and theinertia switch then to the pumps I was reading a post that said the high pressure pump is under the driver on the frame not sure tho. I added u to buddie list and spend alot of time on computer being underemployed really sucks lots of time no money to do what I want.
