Both fuel pumps not working! - Page 4

kamylion · 19th January 2015, 12:27

Just done some volt readings trying to follow this thread http://www.the75andztclub.co.uk/foru...ad.php?t=69308 ,
does this all seem ok?

These are on the V- with 3 dots underneath the line and turned to 20 and all taken with key on position 2.

Car battery now at 11.89
Low pressure is 4.99
High pressure is 4.99
Plug on top of ubp is 11.66
Cam sensor is 11.66

Also just a reminder that the in tank pump is working but not the ubp.

Also just noticed that it appears that fuel is coming up into the electrical plug on top of the ubp, is that normal?

As David says it certainly isn't. This has been seen before with some cheap pattern pumps.

Good job you spotted it as, given enough time, diesel will track down inside the cable insulation and soak the cabin fusebox.

Oh........ I did notice a drizzle mark on the sponge on inside of cabin fuse box cover too, didn't know what it could be so that'll be that then

A big thank you to Steve811 for letting me buy your spare ubp last night

Turns out the fault was the pump like you all told me, now it's running good again
