Right then ladies&gents........I'm in need of your assistance to help me help my stranded mate in france. The car: 1992 Astra GSi 16v XE The story: He is currently visiting his parents over in France but during a bit of a sunday drive he had an accident involving a deer  and made a bit of a mess of the front of his car. Oh well, these things happen so he bought a scrapper base-spec astra to rob the wings&bonnet+various other bits to make his car tidy enough to get it back to the uk. The problem: Car is now structually sound.........but it wont run properly  He has gone through all the usual checks-got spark, got fuel pressure. When the car was hit, it didnt damage anything in the engine bay......just outer bodywork. Ive just got off the phone with him and apparently it will start every now and again but run really rough and then cut out, ive told him(just on the off chance) to check the cam timing as it may have slipped a tooth or two..........but I'm only clutching at straws on that one. Would anyone else have any other ideas? He wants to make his way back next week and doesnt want to have to leave his beloved car behind  Cheers folks Steve  |

Airbox full of giblets? Sorry that's not very helpful, really hard to diagnose this sort of thing  if it's got spark & fuel that only really leaves timing (as you've said) and air (as I've said).. HC. |

I know mate, really frustrating being so far away from the car  He's gonna check the timing either tonight or in the morn and hopefully let me know what happens soon after..........i wanna know whats wrong with it! |

Probably a sensor of some sort. Can he get access to a fault code reader? Potentially daft question but has to be asked: how much fuel is in it?

No access to a fault code reader(but even then you can rig it up to flash up any fault codes by bridging a couple of terminals in the engine bay but cant remember which ones ), and since whenever the engine does run it doesnt run long enough to flash the ecu light up |

No sharp ripped pannels has cut through any of the wiring? or the a sensor has been damaged (possibly crank sensor) Thats all I can think of.

just a guess here but it hasnt got some form of inertial cut off in case of fire? i know grannys had them and needed resetting after a bump.like i said just a guess.

But other than giblets, all the other explanations are just as possible. Offer to give him a hand if he covers your costs to get over there, Steve  |

If it was the cutout, it wouldn't have fuel pressure and wouldn't start at all though..
now, do XE engined astras still have a distributor? (I suspect that they do.. and that the cap is perilously close to the front panel as it runs off the back of the exhaust cam) I'd be looking there first.. might just be knocked, might be bust but IMO more likely a cause than jumped timing (unless the drivers wing was well caved in and the belt cover cracked... then I'd worry)

To get a standard A40 this low, you'd have to dig a hole to put it in |

Doubt it's fuel cut off - it should start again.
Try towing it in gear while turning the engine over, I bet it starts.

cold start sensors don't like thumps they are located just above the left hand engine mount
at the front off the block
they will over fuel until they get up to tempature
also as ryan said check the crank sensor as they are at the front just below the cold start sensor

You can check the error codes on the xe without the engine running. All the info for how to read the codes is on www.topbuzz.co.uk/When you bridge the 2 connections with the ignition on the CEL light on the dash will flash the error codes stored in the ecu. It first flashes a code to say its in diagnostic mode (and flashes each code 3 times so you are sure you've got it right) With the engine not running the first code after that will be crank sensor. This doesn't mean that it is actually faulty but as the engine isn't rotating the ecu isn't getting a signal from it. It is possible that you won't get any codes but its worth a try as its so simple to do. Other things i've had with XE's over the years. Fuel pump relay that pumped briefly to pressure when ignition turned on, but didn't run pump when cranking so wouldn't start. Remove the relay and bridge a wire to run the pump then try starting it. One car wouldn't start and after lots of cranking a loose plug on the dizzy was spotted and fixed. But the car still wouldn't start. Took plugs out to find they were soaking wet from all the cranking without spark. New plugs fitted and it started first time. Dead crank sensor stops the igntion from sparking when cranking (as the ecu didn't know the engine was going around) so i doubt its that if he's getting spark Bad engine earth wires can cause all sorts of issues with the XE's worth clamping a jump lead to the battery neg from the engine to check that isn't an issue. That might give you a few more things to look at. |

check crank sensor would be my bet.
