Went up to the lock up tonight to fire up the Carlton and get it ready for the summer,now its sat all winter in there and I've only had it running once since it went in there last year.
The battery has been off all the time,connected it up and turned on the key every thing lit up as it should but the fuel pump relay was clicking,the dual ram solenoid was moving back and fore and the injectors were firing,tryed starting it and it did start after a bit.
Ive checked all the earth wires fitted a new fuel pump relay but still the same,I'm thinking the ecu is going tits up.
Anybody else seen this before.
by the way for those that don't know my car it's a GSI 24v and has an ABS chip in it.

I suggest that the first check should still be the battery voltage when you switch the ignition on  |

Now got a meter on the battery today.car switched on before cranking 12.01v and while cranking 11.4v. After the car was running for 5 minutes I switched it off and when turned it back on all was fine.  . So I've taking the battery of and back to my other garage where I've stuck it on the smart charger where it's only reading 60%,but it is taking a charge. The thing that gets me is it can still start the car with only 60% in it,when it's cranking I would say it seems like it's cranking at normal speed,strange one. |

If that was my battery, I would be deeply suspicious that it was the cause of my problems !
A fully charged battery, with all cells in good order should read significantly more than 12 volts and shouldn't drop below 12 when cranking.
A smart charger only looks at the voltage on charge, if you have one or more cells that are relatively high resistance, the charging current will cause the voltage to rise quickly to a point where the charger reduces the current because it believes the battery is fully charged.
As I have said in that link, it can seem to be cranking normally even if it's nackered.

I agree about the battery, 12.4v is about the least you can call a charged battery.
On the other hand Ive had an ECU fail in a 24v GSI where the symptoms were that it would start occassionally but stop at any time, when the ignition was on and engine not running the injectors were sometimes chattering.
ECU was at fault but I have no idea what was wrong with it, replacement cured the problem.
It wasnt storing any codes even thought the light was on some of the time.

I looks like it,strange thing about it is its fine after a short run.would have to be the one with the ABS chip in it,I do have a couple of spare standard ones to try.
The battery is only a couple of years old.

Mine has an ABS mark3 chip in it - sometimes the EML comes on, but usually goes out if engine is stopped a few minutes after starting - like when getting petrol. Start up again, EML usually goes out. Not being funny ( when people say that, they really are being funny, don't you think?), but I wonder if the chip could be buggered? |

Start up again, EML usually goes out. Didn't Ian Marsh suggest once on the ABS forum that these EML symptoms above could also be caused by the 24v's Distributor? |

My cavalier turbo used to do that all the time,which had something to do with the crank sensor. there was a fix for that on the cav turbo web site something to do with the green wire,but cant remember. |

Got a chance to work with it tonight and fitted a standard ECU,all that strange things it was doing has stopped.also it runs like a clock now,much smoother and no more of that surging that it used to do.
So off to the post office tomorrow to get raped.

going to try the chip in an other ECU and see how it goes,if not I think I'll just put the cats back in and leave in the standard ECU,runs way smoother.
IMO

Thinking of doing the same - getting a right handful at times!
Although I have just bought an IH throttle body, so gonna try that with the chip and the exhaust first.
