1.9tdi abs problems - no start.

Post by jclay »

Hi guys, this is my last chance before i decide to sell the car as a non runner so any help will be much appreciated!

Story goes,
Back in Jan, i started the car but it soon stopped about 100m later. Called the AA, and basically came to the conclusion that the fuel lift pump in the tank isn't priming.
Replaced the pump but nothing, checked all the fuses and all good. Same for the 109 relay. My brother plugged in diagnostics and cleared some fault codes and it started up and ran for 3-5 minutes. After that it hasn't started again. Dropped it in to a friend who works with seat and he had a look. Came to the conclusion that the ECU isn't communicating to the abs unit. Brought a second hand working abs module, plugged that in and still diagnosing as no connection to abs module.

Last diagnostics scan returned this (yes its the lite version, i'll get a full version scan for tomorrow):

A fault in the ABS controller wont cause it to fail to start. Not quite sure how your mate managed to come to that conclusion

Is it cranking but just not starting?

Have you had the compression tested?

Have you had the injectors removed to see if fuel is actually coming down the lines?

Is there damage to the wiring loom? Presume you have checked all fuses with a multimeter and also the battery side fuses?
