Re: Audi 100 5cyl cold start problem
All injectors should run on start up the cold start relay is only there to
add extra fuel when its cold like a choke

Caleb,
If you can hear the fuel pump running, and you're having a fuel delivery
problem (manually lifting plate does not provide full flow to injectors), I
would check the following:
- replace the fuel filter
- if fuel delivery is still a problem, there may be problems with the fuel
pump pre-filter (a screen mounted on the intake of the pump - may get
clogged with dirt), or fuel distributor problem.
The Bentley Manual has a diagnostic procedure that you could follow, as well
as Scott Mockry's site at:

Re: Audi 100 5cyl cold start problem
Well I have temporarily resolved the problem, I was just buying this
car last night so I wanted to make sure the problem wasnt too terrible
before i bought it. It turns out the cold start injector was not
getting any power and to make matters worse i mustve knocked the
distributor feedback plug out but i found that early enough. So i
shorted the injector straight to the battery when cranking and for a
short while afterwards and it worked flawlessly (although a slightly
rich mixture for a few seconds) So now my only problem is to find out
why there is no voltage to the cold start. The temperature guage is
also not working which i will have to sort out.
Anyone got any ideas on why it would stall when stopped and in gear
with the brake on? only did this twice in a 40 minute drive.
