1991 Audi 100 10v catalyst Bosch KE CIS - won't run

[David Boyd]

Completely stumped by fault on above - engine will start and run for a
few seconds then dies every time. Appears to be plenty of fuel pressure
to fuel distributor but none to injectors. Have replaced fuel
distributor with a used unit but to  no effect.

Attempts to blink fault codes from twin connectors under dash using an
LED don't seem to work (although have done this successfully in the
past) - LED glows brightly when shorted to other terminal connector or
when fuse is in fuel pump relay but when either are disconnected after 4
secs. with ignition still on the LED just glows dimly and flashes not at
all.

Speedo on this car is currently inoperative - it has been erratic for
some years and now does not operate at all, although the car ran OK for
some time with the inoperative speed. - mention this 'COs the Bentley
seems to  mention that the transmission sender/speedometer need to be
good.

Any suggestions most gratefully received.


Regards


David Boyd
