What sort of volage should I see at the fuel pump, cars a 2wd Saph. I seem to have a misfire and think this may be the problem as I'm running a coilpack.

in the ideal world you would see exactly what you have at the battery,

its also worth looking at the alternator to battery wire, replacing this can gain more than 2vs at the battery, in turn this will increase the fuel pump voltage.....

Going to check the voltage this morning at the pump, I assume I should see a slight drop due to its distance from the battery. Only now I can't get the car on the driveway as the fuel pumps gone on my brothers escort and we can't move it off the drive

As above,wants to be as near to battery voltage as possible

Pretty sure it will need re-wiring

Not too bad a job to do,lots of posts on here if you do a search

Yup, should be around 14v mate

Got 14 at the battery and 12 at the pump, did find that the plug in the boot was loose and was causing the pump to cut in and out. I've cut the plug out now rejoined the cables using bullet connectors i'm not a fan of these but i intend to re do the wiring once I've resprayed my runaround.
