Hi, the engines turning, i can smell the unburnt fuel dripping out of the exhaust lol - also fuel pump stirring on ignition, using a timing light i see it has no spark, i replaced the coil but it still wont start- still has no spark.

what is my next port of call ?

thought id post here and consult the haynes at the same time
cheers folks !

 

So the coil has power which I should think it does but check to be sure...

After that you want to be looking toward the ignition amp.

Hi martin thanks for the reply, im half way through moving house, my haynes is packed somewhere lol ???
ive never learned much about this engine which is why im here, i forgot to mention it was an instant breakdown as such and not progressive ( if it matters ? )

do you have any idea where abouts the ignition amp is and how to check it ? does this engine have an electronic spark control ? i think not ?

cheers Anthony

 

Nope it does, in actual fact it has Ford EEC IV management to be specifc (Yours should also be fuel injected?), we have a model which employs the "ESC Hybrid" setup.

I think, but I am not sure the amp may be near the exhaust manifold on your car.

Martin

 

the eec iv sounds like an ecu number for the car rather than just a esc, is it built in to the computer then or a seperate unit - sorry dont know anything about this car, ill look for the amp tmrw hope it is it ?

 

ECU sensor (close by the oil filter).

 

Ford EEC is a ECU, and it's all contained within the unit, older setups had an "EDIS" which you may be thinking of.

Martin

 

thanks for the input
what does this sensor do ? how can i check it ?
Anthony

 

By this I am guessing you mean the CPS?

I still say the amp.

Martin

 

the more ive read the more i think your right, i rekon it got heat soaked last time i shut the engine down and poof. just been researching ways to test it.............................

imo rare that a crank/cam sensor should fail instantly like that,id expect real poor running first....

 

does anybody know if it is torx/philips/rivited on ? cant get my head in low enough to see down the deep holes - manifolds in the way thanks, ive done some testing believe it is fried will buy one tmrw. thnx guys fingers crossed eh !

 

So I was right with the location then, it's a daft place to put it seen as heat is there enemy

I should think there screwed on, as riveting would make it hard to replace.

Martin

 

it sends the top slack point (dunno how to describe it) from the crankshaft, sometimes we call it motor management. no signal means no starting engine. Sometimes the oil destroys it, cause the oil filter is nearly above. Sorry, haven't a tip to check it. Most of the starting probs caused by this. I would buy a new one for testing.

Sorry, dunno exactly, we call it top slack point encoder or motorcontrol. CPS means Crankhaft position sensor? So you're right I guess.

 

Abit late but just to finish this thread off it was the ignition amp, good call its not the first time its had one either - not surprising being sat next to the exhaust, im getting back into the habit of running the heaters on full before i stop after hard driving - something i always used to do on the xr4x4 i had.
thanks for the help everyone, happy xmas and happy new year !

 

What do I win haha? As to the heat issue maybe a heatshield would help?

Please leave rep power.
