Intermittent no start.

Came to us from another workshop.

On occasion would lose spark and injection pulse.

They tried new coil and pickup in distributor, new relays then another used distributor, still no start. They were at the point of trying another ecu before they rang for help. I ran them through a diagnostic sequence of testing for power and earths, fuses ,lights ,alternator and battery tests, they said all tested good. I instructed them to obtain a wiring diagram and go over it again.

I had a feeling they were missing something. Still no luck and no fault codes on scan. The next day it arrived at our workshop on a tow truck.
