Bore wash!!!

Been trying to sort out the Cortina for weeks now, and getting ready to fire it up in its new configuration,
When turning it over on the starter, its trying to fire, but it sounds like its 180 out, now this has me confused, as its crank triggerd wasted spark system, so, we put 180degrees of ign timing into the ECU, AHH life in the engine at last, but only firing on 4 of 8, take the plugs out, and they are DRY, not a hint of fuel, that will be an injector trigger fault then so I pull the injectors out with rail, and crank, sure enough only 4 are working, have a little fiddle in the computer to reset everything, and all are now working, back together now and crank it over, nothing is firing now, Mmmmm bugger, lets see if the plugs are still dry, take out No1, and its got fuel dripping off it, all the other plugs are soaking, time for new plugs, thought I would crank the engine over without the plugs in to dry it out, whizz it over and out of each plug hole came a JET of neat petrol, not just a mist, but a 1/2" dia jet of neat fuel squirted out, Ever seen the jumping water in the water parks, well it was like that, 8 injectors locking open and pumping fuel @4 bar is a fair bit of fuel going into the engine,
Ive now spoken to a couple of people, who have both said the same thing, The ECU has crashed, not a problem to sort, but its the reason why it has crashed thats bothering be, and both have said its probably electrical noise thats caused the problem as I have done minimal electrical mods, just re routed the ECU loom
Needless to say, I have walked away from the car, yet again, its trying my paitience, one stray spark and the thing would be history,
Tomorrow its back out there, reboot the ECU, check all my wiring for faults and plugs in the right place, God knows what sort of backfire Im going to have if it starts with all that petrol in the exhaust, probably take out the back wall of the garage, Well I want to build a new garage, sounds like a good excuse to start demolishing it,
I must say thanks to Reg for dropping everything to help me try and sort this minor hiccup,

Ian,

We need to check the wiring to the coil packs as we think there reversed. Then we can reset the ignition timing.

When I spoke to Dave Walker I got the impression the the injector start and stop times may now be confused with the timing set to 248 rather than 68 degrees and this would trigger the injectors many more time than required. It sort of makes sense.

Let me know when you want the timing changed back, can come over later if you not working.

another option is we could upload my map and config to your ecu and try it on my car. That will prove if the ecu is fubared.

Reg, friday afternoon is probably the next time I will have a chance to have a real go at it,
1st thing to do is change the oil, Just pulled the dipstick, its up at least 25mm on a couple of days ago, funnily smells of petrol, and has the consistancy of WD40, another 8 litres down the tip, all brand new Valveoline racing oil, gonna get some Cheap stuff this time, £50+ on oil just to pour it away is a bit too expensive for me at the moment,
Tesco or Asda special sounds good at the moment.
Funny thing about what you say about the addition of timing, I seem to remember something like this happening to somebody whan they put sh-t loads of timing in the engine, The ECU sees the timing, and reasons you cant run in this mode then tries to compensate, then throws a wobbly and spits out the dummy.

I assume you're on the right lines already, but I thought I'd mention a discussion I had with Paul at PPC earlier. I rang to see if the car was ready and was told that he'd just shut it off and it was all working fine.

I went in today and he said "just after I spoke to you yesterday your car stopped running and wouldn't start. It just pumped tons of fuel into the system and died".

He found out it was the water temp sensor that had packed up and the ecu thought the water temp was -3 or something and pumping tons of fuel in according to its enrichment settings.

However, I don't think it actually turned into a pyrotechnic water hazard though, just severely flooded.

New sensor and it was fine. Thank god it went at the garage instead of on the way home!!

I haven't posted much on my MS setup as i have had loads of problems, what i have found out, is that if the MS gets "spiked" at anytime, everything goes to pot ! i had a couple of weeks trying to work out what was going on till i noticed it was running at idle with a duty cycle of something like 25% and 8m/sec open time, i too dipped the oil and found it to be about 3 inches up the dipstick !!! it was then i reloaded everything from the boot jumper bit ! put on a program and it ticked over sweet as a nut ! but not being happy with that and doing a long trip to Billing NSRA fun run, i decided to use one of those plug in adapters that allows you to put in the normal 240v power supply, maybe starting the engine first would have been a good idea it spiked the MS again, with too low a voltage and i franticaly tried to work out what i'd done ! in the end i reloaded it all again and it fired and run again as smooth as always, sorry for the long post, but it might help ! john

Ian did have a problem with his coolent sensor, well think it was not connected so that may have had something to do with it but thats sorted now.

It was funny seeing the fuel comming from the injectors, it reminded me when my son was having his nappy changed by the midwife some 16 years ago

Your boy could pee a long way then, the fuel was hitting the garage wall!!!

You should have seen the state or the midwife
