Update.

Half tank of petrol.

Absolutely no sign of it sparking up. SFA.

Should I be able to hear the fuel pump activate when I switch on the ignition?

Because it spins without any sign of life my money is on either a faulty fuel pump or a faulty crank sensor. Both of which are 17/18 years old.

I don't buy the 'flooded' argument. No codes.

What code would you expect to get for flooded? P003.8% for cheap fizzy lager?


If the fuel pump doesn't turn with the ignition on(many don't) it absolutely must when the engine is cranking. So that's an easy test.


As is checking that there is fuel and pressure at the fuel rail. The pressure is just as important as the fuel supply. It's fuel injection after all.


Even easier is using the tool - that didn't give a flooded code - to read the live data from the crank sensor.


They're both 17 years old is  true; crank sensors are a common failure on managed engines and submerged pumps do need to sit in enough fuel to keep cool and lubricated.

Are you going to make this your life's work? Whats left of it, anyway.

Go walk the whippet and let people who know about cars offer constructive advice.

People who know about cars don't spend weeks asking other people why it won't start. 

As I don't know (that much) about cars I tend to ask people who do know about cars. People such as Mark DTM, and the ever cheerful Nick W.

I don't want you to feel left out though, and if I need to know how to steal a car, or clone a car, you'll be the first I ask. Promise.

Thanks Nick.


I wasn't expecting a code for flooding. The short sentence 'No codes' was just to reiterate there were still no codes when attached to the code reader.

So what would you bet on as the problem?

[Raeturbo]

Are the plugs sparking then? (Always a good place to start

[STEMO]

Are the wheels round (except for the little flat bit on the bottom)?

[Field Marshal Dr. Opti]

Are the plugs sparking then? (Always a good place to start

I haven't got around to lifting the coil/dis pack yet but I doubt plugs are the problem. I would expect it to at least 'try to start' even if it won't catch.

Completely dead.

[Raeturbo]

No I’m asking are you getting a spark from the plugs that is the first place to look

[Field Marshal Dr. Opti]

Are there specific codes for a faulty fuel pump or crank sensor?

You haven't answered my question.

Lift the coil pack but leave connected and plug a couple of spark plugs in,crank and see if you have spark,you'll be be halfway to knowing what's wrong then

[Field Marshal Dr. Opti]

I'll need to lift the coil pack to reach the plugs unless I'm doing something wrong.

[Field Marshal Dr. Opti]

.....and before anyone asks. I know to lift the coil pack rather than prise it off with a hammer and a screwdriver.

[78bex]

does the earlier Corsa need the clutch pedal pressed in to start it  just asking 

[Nick W]

Highly unlikely.
But the physical checks are easy.
I'd start with the fuel because less dismantling is required than checking for a spark.
That's the reverse of older cars with plug leads.
Unless you have one of the gadgets that rest on top of a coil pack......

.....and before anyone asks. I know to lift the coil pack rather than prise it off with a hammer and a screwdriver.

you remove the 2 torx that clamp it down and fit/screw in bigger (m8 thread i think) bolts and lift up on those ,so it comes out evenly

takes longer to get the tool box out than pull the coil pack

no point in guessing, or asking here what other people's guess is

just go check the pump(can you hear it ?) , fuel at the rail ? and plugs 

no lightning when cranking = no worky
