Engine cuts out

[1200 bandit 10]

Had the 2.0 16 V Corrado in work to day to check on the oil leak (replaced the sump gasket)

No leaks.

When on the ramp fuel pump stops,engine cut out.

Turn the key the fuel pump priming,crank the engine none start

Crank the engine 4/5 times engine runs lumpy then clears and runs ok

Has got a NEW FUEL PUMP AND FILTER FITTED.the fuel pump is very noisy (Buzzing sound)

The ing barrel is working the lights on dash,radio ect

Can be alright then all gos wrong.can not check for live feed to the pump as very erratic

I am thinking pump ???

What's the thing that's next to the pump just to the right when looking up at the pump

Any information welcome

The fuel pressure accumulator is located there.

The high pressure fuel pump does indeed buzz, depends on what kind of pitch the buzzing is though, loud or just a hum? Did you change the low pressure supply fuel pump or the high pressure one?

Could be the intank primer pump that's on its last legs and not providing sufficient fuel to prime the swirl pot and main pump. Next time it cuts out, connect up a length of wire and a 12v test lamp, bring the test lamp with you whilst sitting in the driver's seat and see if the light goes out when the engine cuts out, if it does, check the fuel pumps relè, connections on the pump, wiring etc.

Sounds like a classic symptom of a buggered primer pump though.

Is the primer pump in the fuel tank

The new pump is under the car by the fuel pump(roughly about the same size as the fuel filter)

the buzzing is quite loud more so when 6/7 miles covered

Where about is the low pressure pump

Is the 3 fuel pumps fitted??

What is the best Haynes manual to get to expand the fuel system and gear linkage

You won't find a Haynes manual for the corrado mate, they never produced one.. Only for the Passat or mk2 golf. I've got the Bentley version which is ok I suppose.

Only two pumps present, the lift pump and main, large pump under the car.

The lift pump is located inside the fuel tank, it's part of the float unit. Lift the carpet, remove the black metal inspection plate screwed down with 3 cross head screws, Disconnect the fuel feed and return pipes, electrical connector, then undo the retaining ring and gently pull the whole unit up and out of the fuel tank, being careful not to bend the float arm whilst removing.

Mark the float housing to tank first to keep the float aligned at the correct angle.

Try feeding the pump directly off a spare 12v source ( AVOIDING sparks and well away from the open fuel tank's petrol fumes..)and see if the pump runs for a bit or if it runs then stops.

Thanks for the reply much appreciated

The is a new pump under the car by the fuel filter (fitted by the previous owner)

This cutting out and worn gear linkage is the only thing that stops the Corrado being %

Will remove the tank unit and check,is the a filter inside the tank ?

You might find a strainer type that's on the bottom of the pump, just give it a blast with compressed air to clean out any muck accumulated.

Let me know how you get on and explain the gear change problem, too much play? Can't get gears properly?

Let me know mate and I'll give you details outlined in the Bentley manual.

Cheers.

Ok Wayne, no problem mate, keep me posted.

[1200 bandit 10]

Removed the tank sender unit today and found a bit of sponge inside the fuel tank

Have ordered a in tank fuel pump so hopefully all sorted ?

Just got the gear linkage to do,Deep joy

[1200 bandit 10]

So now the fuel tank is empty,clean out the tank and it’s dry,did find dirt in the bottom of the tank

Just waiting for the pump to arrive

[1200 bandit 10]

Got a in tank fuel pump fitted ,start engine idles at 11,000 RPM when getting warm

Got a fault CLOSE THROTTLE POSITION SWITCH OPEN CIRCUIT,SHORT WITH POWER (sanp on scanner)

Check the wiring to,the throttle switch,remove the tape from the wiring ,checked the wiring found the blue wire snapped,carried out repair and now starts and idles at 8,000 RPM

So l think l have sorted the idle fault

Hope that's 800rpm you mean mate

 

Glad you've sorted it, those pumps are a pain when they start to go wrong

Is it running a motorbike engine with that sort of RPM ??????

[1200 bandit 10]

Yes 800 RPM just checking to see if anyone looking

Engine runs spot on from cold,I think the snapped wiring is why it was cutting out

[1200 bandit 10]

Carried out full scan tonight comes back all clear on injection and ABS happy days

Congratulations on sorting it

[1200 bandit 10]

This is a happy ending as was going to sell it because it done my head in

Just a few more bits to do then it will be 100%

now going to keep the Corrado

[1200 bandit 10]

Just an update

Went out in the Corrado on Saturday,covered about 15 miles all good the fuel is NOT noisy now,

Get a bit more comfortable in the Corrado,although it has always got me home so can be all bad
