Poor starting

Post by mac27040 » Sun Jul 31, 2022 9:42 pm

Had a problem since swapping engine, had a intermittent starting problem, sometimes it would start first time, other times it would start on second turn.

I have replaced ignition switch, fuel pump relay, DME relay, had new spark plugs and coil packs.

In the end it looks like crank sensor!!
Swapped it tonight and wow what a difference, car starts first time but more important it fly’s !!

If you have starting issues like me but no engine light then check sensor.

all sorted, crank sensor helped but changed both cam sensors and car runs fine.
