==================================================
= VS Fuel Pump - Test + Diagnosis - How To Bridge the Fuel Pump Relay =
Take out the FP relay (in the engine bay) and bridge (connect) the appropriate pin slots with some thickish electrical wire.
(On my 95 VS Exec (Dual Fuel), it was the first two slots, nearest the firewall (or back of the car) - CHECK the wiring diagram on the actual relay to be sure!)
Now concentrate...as there's power to one of these slots ALL of the time.
CAUTION: Be careful to avoid sparks...if you're sloppy you may blow the 15A Fuel Pump fuse found next to the relay you're working on.
This bridge will give you constant power to the pump (even if your car keys are in your pocket) - so the pump should run continuously.
HINTS:
The trick is to get the right bridging wire...skinny enough to go in...thick enough to make a good connection.
Make sure the relay box is well lit...you don't want to be fumbling around down there.
Some peeps rig up a little device to make things easier...like a wire with pins or electrical connectors/blades.
I put nodules of solder on my wire and filed them to a point for easy insertion. (Saves twirling the ends all the time.)
This is a great test...and to me, quite mandatory if you're having probs.
It may even get you going if you're stuck somewhere...
...as it overrides the relay and will give a failing fuel pump a darn good kick in the guts!
