No current on fuelpump ignition on

Postby watnweertje » Wed Jan 18, 2017 1:24 pm

Hello.

Hope to find the answer here...I live in the Netherlands but no one seems to know the answer.
Hope my English is not to bad.

When the ignition is on I got no +12v on the fuelpump,but with a bypass it works,so not broken or bad earth.
Wiring is also ok.
Immobilising is off.
The ignition coils get also no +12v.
The fuelpump and ignition coils get the cuurent from the protection and switchingunit.
This one I changed for another one,but still the same.
All the wiring is ok and all the earth also.
On the upc(protection and switchingunit)there are 2 points for +12v.
These are constantly +12v which is ok.
In the upc unit are 2 relays that work on -12v.
Seems to be that I got no -12v on the points ......connection P2 and the one with the big bolt.
Everything else works.....wipers,lighting,windows.....
The engine cranks when starting but wont fire up.-12v is at connector PEM TRACK 1 and 2(connection 1AC and 3 AA)
The wiring of these 2 goes to the injection computer ,the brown connector track D4 (3AA)and the big black connector track D1(3AC).
The wiring is ok,also all the fuses.

Any ideas?

Thnx......
