Hi guys hope you can help...
me and a phil2002 have recently rewired my 044 fuel pump as i was only getting 7volts through original wiring loom after rewiring i have a healthy 13volts.
The problem i have got is the car will no longer tick over when cold. Has anybody got any ideas what may have caused this?
Also, is there anyway of testing the idle speed control valve?
Thanks for your help!
The car is a 3dr Sierra Cossie on level 6

The easiest way to test the ISCV is to simply disconnect it with the engine running (On a cold start), if the revs drop then it shows it to be working, if no change then it's not working.
I doubt it will be running rich, if it otherwise runs ok? Easiest thing would be to check the fuel pressure.
Does it run at cold if you give it some revs?
