Title: Engine not firing 2.3 ('98) R Plate
Post by Christopher_Dean on Mar 28^th, 2006, 12:06pm

Yesterday after finally getting the airbag shorted I thought that my problems were over. The car was running well with loads of power and had a smooth tick-over. I parked the car at my brothers for about an hour. When I restarted the engine it was lumpy and sounded like it was not firing on one of the cylinders. I checked all the fuel injector connections and one was lose so I carefully removed, reconnected and re-clipped all three back into place with a small sqirt of WD40 to aid contact. Still no improvement. I remove the spark plug cover, looked at the wiring and seeing nothing amiss removed the spark plug lead nearest the front on the engine to have a look. Replaced the spark plug lead and now the engine will not fire at all. I have checked fused 21, 34, 37 & 42 and also visably checked the loom for any obvious loose connections.

Please help.

Chris

did you have the battery disconnected?

if so, disconnect it again and leave if for 5 mins then reconnect making sure the ignitions off

is the Maf connection ok?

try that first anyway

Hi Highlander,

I didn't disconnect the battery when I was fiddling with the connections. Will try your solution and come back to you in about 10 minutes.

Many thanks

Chris

life on the edge!! ;D

I'd advise disconnecting the battery next time you are checking airbag connections ;)

fuel cut off switch in the boot maybe?

possibly wiring?

plenty petrol in it? ;)

I was very careful about disconnecting the battery for at least 15 minutes before doing anything with the airbag.

I've checked the fuel cut-off - okay. Lots of petrol. Looks like it might be a new wiring loom.

I had a similar occurance of your initial problem on my 2.3. It was a coil pack that had gone down. If after moving the wiring the second pack has stopped firing I would re-check the wiring again particularly where it comes in at the back end.

Had this problem on my previous '95 Scorpio. Wiring under top cover was brittle & exposed in places. Put shrink wrapping around them - no difference, replaced HT leads - no difference, replaced both coil packs - sorted!! £60 each from Fords

Is there anyway to check that the coil packs are faulty?

replace them with a known working unit i think is the only easy way

I've identified the faulty coil pack. Upon very close inspection there's a small crack where the plug fitting meets the main body.

Are the coil packs available via Partco etc or is it a Ford Main dealer only part? Also, do I have to replace both of the Coils or can I just replace the faulty one?

Many thanks

Chris

I seem to remember that I did shop around for pattern parts but everyone I spoke to told me it was a Ford part only. As for replacing just the one, I'm not sure as I just replaced both for the hell of it, but I suppose if only one of them looks to be causing the problem then I don't see why you should have to replace both.
I must add that replacing both coil packs sorted my car out, but I wouldn't like to advise you that that is definately the problem. I just took a chance at the time & hoped for the best.
P.S. what kind of state was your old matrix in when you took it out?

Chris, Have you read this http://www.fordscorpio.co.uk/dohcloom.htm as it has a good picture of damage to one of these units. You could ask on parts wanted and see if anyone has a coil pack.

Hi Simmo,

One of the packs is definately faulty, where the spring clip fitting mates to the body of the pack there was a crack and you could clearly see the two wires going into the main bady of the coil.

The wiring loom is in good shape, I checked all of the connectors and tbhey all look good.

I've just bought 2 new coil packs from my local Ford dealer. Fortunately, my father is an retired Ford employee and I have his discount card. I managed to get the 2 coil packs and the leads for £82.

Just waiting for a break in the weather to install (it rains alot in Wales).

Thanks for your advise

Chris

Big thanks to everyone for support and advice.

Fitted the Coils and leads, it's now running as smoothly as ever.

Cheers
