My gut instinct is yes you can, but I've not come across anyone that has tried it. If your fuel pump relay died while driving you'd know it damn quick. I'm not sure if an engine stopping suddenly like that would lock up the rear wheels or cause other damage.

the fuel pump stopping wouldn't lock the enginge surely!! It would just wind down as if you had ran out of fuel.

The wheels would turn the engine over im sure?

My oil pressure switch is leaking I belive. No where above it is wet, and it seems to be above the pressure guage sender. Unfortunately I don't have access to one on the shelf in the UK to try it.

My question...

Can I disconnect the switch, screw in a blank and get the engine running? It sounds like this pressure switch is not essential for running, or even very usefull for that matter.

Thanks in advance

The oil pressure switch is a back up power source for the fuel pump. As long as your fuel pump relay is in working order, go ahead and plug it.
