As the firing order has been confirmed, I would change DIS.  It could feasibly be output stage on ECU, or wiring in between, but try DIS first as most likely

I will do Jamie, I'm on the lookout for a new DIS to try. unfortunately I broke the DIS on the donor car manhandling it  :'(

If that fails, I've got a spare ECU..loom... if needed

It's gonna run one way or another

Unlike to be ecu or loom. If is ECU, you'll need immobiliser unit as well (or get ECU reprogrammed)

Are there any codes to be read from the ecu does the dash light appear when your trying to start it.

May help to confirm whether the sparks are being picked up when firing.

Hope this make sense.

Well, Bad, bad news. I bought another DIS, thinking it would sort this problem,  and still the car has the same symptoms as before, it will not  start, although it gets SO close,  and practiically "runs" on the key.

I've not done much cranking though because it should start. I'm at a loss now.

Still get code 19, which is incorrect signal from crank sensor, but I've changed that sensor and its made no difference. I've also put new plug leads on. And the order is 100% correct. Valve timing is spot on too.

Strange thing is, this car DID run briefly a few weeks ago, on all  4 cyls, but it hasn't done so since.

I really don't know what else to try.

Any ideas? Before I set it on fire?!

It seems to crank over a few times, then stop, like it's met compression, and then crank again. its cranking quickly, plenty of battery power, no problems there.

Given that it did start once, it doesn't seem to be a mechanical issue, eg something set up wrong. Would there be any advantage in changing all the inlet stuff and injectors?

:( :( :( :(

Any ideas? ...

My 2.2 CIH Carlton years ago did this, and it turned out to be the fuel pump relay. (Can't remember the whys & wherefores though)

Was it a new sensor?  Having a 19 stored is bad news.

not sure if 2.0 is same, but a 2.2 will start (just) and run (like a bag of shite) with a failed crank sensor...
