Hi there,

You need to scan the ECM for codes first.

Can you check for spark?


Customer: replied 1 month ago.
How do I do that?
Expert:  Gary replied 1 month ago.

Can you remove two plug leads from one coil, and get a friend to crank the engine.

Spark should jump between the coil towers.

My bet is you have a faulty crankshaft sensor.

Hi again,

Do you need any further help?

I hope my advice has been of assistance to you.

Kind regards
