i was driving down the road when my corsa lost all power, cannot re start it. what could this be?

Answer 1

co2 sensor,fuel problem/electrical who knows maybe aliens flew overhead,maybe you ran outta fuel...........

Answer 2

No power indicates battery first of all. Check the charge.
Then the leads.

By 'lost all power', do you mean you couldn't accelerate or the engine died?
The engine dying also points directly to an electrical fault.
It could also be the Alternator, when you try to restart does the engine turn ok but not fire? Starter motor possibly.
Wont turn over properly? Alternator.

Petrol level?
Don't assume it's an alarm or immobiliser problem as most people seem to. Most of the time it is nothing to do with them at all. The alarm may be affected when there is no electrical power in the vehicle but that doesn't mean that the alarm is the problem.
It could really be anything. I suggest getting a Haynes manual and going through the Fault Diagnosis section.
These manuals are an excellent source of information and can give an accurate indication of exactly what a fault may be!



Good Luck and Happy Motoring!

Answer 3

Hi

First of all, immobilisers DO NOT cause engine failure whilst the engine is running.

If the engine cranks over but just doesn't fire then remove the petrol cap and stand with your ear to it whilst someone turns on the ignition. You should hear a 1 or 2 second buzz or hum from the fuel tank. If not then you need to be checking the fuel pump relay. Please note that when they turn on the ignition they should NOT crank the engine.

If you hear the buzz/hum then your problem is no spark, and this is very highly likely to be down to a failed crank sensor if the engine completely lost all power but everything else works.

Unbolt the coil pack, remove the spark plugs, fit the spark plugs to the coil pack, ensure the metal ends of the plugs are touching the metal of the engine, and then have someone turn over the engine whilst you check for sparks at the plugs.

If none of the plugs are sparking at all then I would suspect the crank sensor because it would be just too much of a coincidence for the coil pack to completely fail.

Another giveaway of a faulty crank sensor is dry spark plugs after cranking the engine over because the injectors would not be pulsed if the crank sensor failed.

the only way that a partially failed coil pack could cause complete engine failure would be if it spiked the ECU and burnt it out.

There should be enough to get you on track here but if you need any more info then mail me.

Answer 4

does it turn over but just not fire or has it just stopped and died with no power to anything? if the first one i'd say a fuel line's come off somewhere , or the fuel pump's died. if the second, you're dropped a power lead somewhere, either the power to the starter from the battery, from the batt to the main fuseboard, or the batt's dead. if it has an immobiliser i'd have that checked out after checking for fuel and power. could do with a bit more information really.

Answer 5

It could be a snapped timing belt, this happened to me in my Laguna a couple of years back. If that is the case it's gonna be a really expensive fix. I wouldn't expect much if any change under a grand (depending on the damage done!).

Answer 6

It aliens man, the have abducted you again and anal probed you.

They forgot to fix your car when they finished probing you. All you have to do now is to Find those aliens again, best way is to go back to the same road the car went off then stand on one side of the road and do a moony at the sky bofore you know it the aliens will be back.

Your memory will be erased by the way

Answer 7

Its a Corsa - did it ever have any power to start with?

Answer 8

Ok, if it cranks and no start, then you may have a bad fuel pump. Another alternative is a broken timing belt. Has it ever been changed? Should be done at 60,000 miles.
good luck.........

Answer 9

Immobiliser error possibly caused by your car alarm if an after market fitment

Answer 10

sorry but it could be a number of things out of gas,battery,alternater,your computer box it sends signals for all types of things or your timing belt

Answer 11

Out of petrol
