1.7 Puma with no spark

Recommended Posts

Hi Guy's,

A customer has got a 1.7 puma (from memory it was a 2000 model) and it suddenly stopped on him.

Ive tried everything and can't get it to spark at the plugs. no error codes are coming up.

I've changed plugs, leads, coil pack, cam shaft sensor, rail loom, another ECU and still nothing.

 

Ive also checked the plug going to the coil pack which the centre pin is live when the ignition is on but I've read that the two outer pins should pulse as a negative when the engine is cranked which it doesn't. Ive checked continuity from them to the ECU and they are fine.

 

Can anyone please give me some help on this?

 

Many thanks in advance

ASH

The one item you have missed off the list is crankshaft sensor?

I guess this car has one, it is the primary timing for ignition. Otherwise you seem to have covered everything I can think of.
