Default Hot wiring the fuel pump.

I have been having a chronic problem with the fuel pump relay and/or the fuse box. Every now and than the truck will randomly decide to not start out of know where. If I pull the relay out of the fuse box wiggle it around a little, clean the terminals, and maybe hit it with a shot of contact cleaner the truck will fire right up and run like a champ until a couple weeks later it decides to not start again. Than the same procedure takes place and back to running like a champ.

I have swapped the relay with another and the problem still occurs.

Im at my wits end with this tiny but annoying problem, unless anyone can see why I should not run power directly to the fuel pump and wire in my own relay, Im planning on doing this tomorrow.

I have done this before in my race car, with zero problems. It is a very common mod to replace the stock power wire with a larger gauge wire to keep the voltage from dropping In the upper RPMS.

Im really just not sure how the Rover will react to this. I know the ecu has some funky coding that tells when to turn the fuel pump on/off and by running a power wire directly to the pump this would by pass all the ecu bullshit that keeps the pump from coming on.

So speak now or forever hold your peace!

Thanks Guys!
