Hi Guys, any help here really appreciated.

I have a 2009 KA 1.2 petrol

The car developed a misfire then ecu died so I got a virgin replacement ecu.

I fitted the replacement ECU and the car started at the first turn of the key and ran super smooth. Happy days.

The last thing I needed to do was a phonic wheel reset to stop the flashing MIL light, basically three big revs on a hot engine.

On the third rev and at the red line the car just instantly died and wont start again. ECU has been checked fine, pack leads and plugs all rechecked fine.

Have I killed it ?? If not where should I be looking now.

Thanks for any advice in advance.

Simon

Why would you rev it to the red line on a 14 year old engine ?

Have you killed it ? Yes, quite probably.

Is the timing chain/belt still in one piece, if not then the engine is scrap.

I get the heebee geebees pushing my 18 year old engine to 4000 Rpm! Despite my mechanic suggesting I feed it BP Ultimate, and redline it a couple of times/tank.

He does have intimate knowledge of my engine though having had it stripped down to replace the original which died of being hydrolocked by previous owner...

I was following the exact step by step procedure described by Ford Etis (And Fiat as the car is really a fiat) to to a phonic wheel adaptive relearn thanks.

It was stationary at the time.

Timing belt is fine starter motor is fine

I can understand that, but the procedure was most probably intended at the time for much newer engines and with lower mileage.

If the timing belt is still in one piece then you're still in with a chance that it may just be a sensor. With it not being a true Ford, unfortunately you can't use FORScan to check for any DTC's.

Have you got a generic code reader ?

There is no other way to do the procedure sadly.

Yes Ive got fiat multiecuscan (dealer level), the car connects fine as a 1.2 fiat 500. It is showing no errors at all.

It was quick to tell me all about the misfire I had previously

Going back to basics, if each cylinder has fuel, and each spark plug has a decent spark the engine should start and run, no matter how bad and how rough. The only thing that would prevent that is if the timing is badly out.

Has the timing belt jumped a tooth ?

Buddy ive totally overlooked the fuel issue, now you say it when i try start the thing it sounds like a car out of petrol (which it isnt) 

How can I check if ive jumped a tooth ??

I need to bow out at this point as I don't know enough about the 1.2 Fiat engine. Perhaps @iantt or @TomsFocus may be able to give further help on checking the timing.

Is the fuel pump OK ?

Is fuel getting into the cylinders? Eg do spark plugs get wet?

Yes, I would strongly recommend going on the Fiat 500 forums for this model.

The only Ford part on this car is the badge

Bingo, there is no fuel inside the engine.

I just fitted a brand new spark plug, turned the engine for 20 seconds, removed the spark plug and I can lick it its so dry and clean.

Thanks unofix and Isetta for getting me this far

Where would every body suggest I hunt first for my fuel issues ?

Checking the fuse for the fuel pump would be a good starting place.

There should be a schrader valve on the fuel rail, check to see you have pressure if not check fuel pump is running. If you do have pressure then injectors are not firing.

With all the other concerns distracting you, you haven't overlooked the red flashing light on your dash requesting you put more petrol in her?? :laugh:
