Vauxhall Astra 1.6 16v Petrol engine will turn over but not fire

[blondievp]

Hi I have a 1.6 16v petrol engine. Its has done about 110,000miles.

The other day I pulled out of a junction and managed to smoke out the car behind me, the car then started to Kangaroo down the road at random intervals, just as I parked up the car was sounding like a tug boat.

Went to start the car the next day and the engine will turn over but will not fire, on rare occasion it will fire and then conk out again after a second or 2.

I have checked and there is fuel getting through, I have got a spark. We found one of the vacum pipes had broken off and have replaced that (have also called the AA out to try and start it and he tried all of the above and still doesnt know why it wont start) Have tried to bump start that car and it will still not fire

Any one have an idea

Thanks vp

it sounds like it has too much fuel getting thru. Try pulling the fuel pump relay out and try to start it. which Vacuum hose was broken ?

No guarantees, but check the temp sensor. They tend to fail in the cold setting, and have the effect of 'putting the choke full on'. A quick check is to pull a plug out and see if it is covered in black soot, and/or fuel.

if the engine management light is on then its the crank sensor. it wont let the engine fire as it thinks that the timing is out. if the engine management light comes on then starts flashing after a few seconds the its an immobiliser fault

If you have a spark then unlikely to be the crank sensor. No point guessing and throwing money at it, put it on a scanner, cheaper in the long run.
