Intermittent crank / no start

Recommended Posts

Hello all,

I have an intermittent condition with my car ( 1992 Escort Cosworth with Link Fury ecuĀ ) where the car will intermittently crank but not start. I have a Motec dash which I will be configuring to display fuel pressure tomorrow but I was wondering in the event this isn't a fuel delivery problem, can I configure the ecu to store a fault if a sensor ( for example crank or cam ) fails to operate ?

Thanks in advance for any input.

Are you getting an RPM signal during the no start condition?

If the engine is using reluctor sensors for cam/crank check your arming voltage table, in some cases I've had to drop the 0rpm voltage to 0.2v to get the engine to sync, also check the polarity is correct

Ya, I confirmed via the laptop that I have both crank & cam signals active when cranking.

Based on this, I confirmed that I had a faulty fuel pump & have replaced it. Running again !
