[Mk2] [Generic] MK2 91 - Sparks, turns but no fire - HELP PLEASE

Post by asellens »

Hi, i have a k reg 91 mk2, for almost 6 months with no problems at all, then yesterday the windscreen washer motor decides to pack up - annoying but not the end of the world.
i go to start her today and turns over fine but no ignition, i've been driving for the last few days in the snow without a problem, i checked a spark plug and solid spark but still no life..... confused. please help, any advice greatly appreciated.

if the engine is turning over.
you are getting a spark at the plugs,
it is more than likely to be fuel related. paul.

Check your fuses, start with the fusebox in the engine bay...a blown EFI fuse could give you the same symptoms

all fuses checked and all fine, in the engine bay and in the front, the EFI resistor is ok too.
tried to turn her over again and sounded a bit different, i presume due to a slightly discharging battery - which is fine btw!

Try Bridging B+ and FP in the diagnostics port, this will have the fuel pump running 100% of the time the ignition is on.

leave ignition in position 2 (dash lights but not running) for a few seconds and try starting it again.


could be fuel pressure / filter related

have you checked for error codes? water temp sensor...cold start switch maybe....I had a very similar prob to this and it eventually went away when I bled the coolant system.
