v5 non runner?

[tonysgti]

my friend has just purchased a golf v5. it is a non runner, its got petrol, got a spark(although looked alittle weak?) but wont run? just turns over? scanned the car and nothing is coming up? any ideas?

[Granta Gti]

Camshaft or crankshaft position sensors?

So many things it could be but sounds sensor related

[tonysgti]

I though sensor but I have scanned it afew times? Nothing came up?

[tonysgti]

any ideas? as its been scanned i thought that would rule out sensors? dont fancy buying sensors for no reason due to money.

Not up on your engine, but I'm sure sometimes the crank sensor doesn't ping codes? Maybe worth trying it!!
Coil pack too?

if you got spark and petrol, but no bang then you most probably got no compressor,

check the cylinders compression.

I suppose the sensors would have thrown up a code, if no compression I think your next bet would be to check the timing ( do the V5s have chains or belts?) if it is belt driven and if nothing from that whip the head off.

Chain driven

Also worth remembering early ones were noted for piston problems
