Why will my 98 passat not start?

Question

The battery is not dead. the starter is new. the engine cranks over. The timing belt is not broke. I thought the diesel pump was away so i replaced it and it still doesn't go. I have changed the relays and it doesn't help. It just winds over but doesn't fire. PLease help.

PLease help. i have changed the glow plugs on the car. the 4 injectors were took off the engine one a time and the diesel is flowing up through them. The car was drinving and stopped dead in the middle of the rwoad. I thought it was dirt in the fuel so i cleaned the tank out and put new diesel in it. Still no luck. Changed all the relays aswell. I think that the brain is away or maybe an earth wire has come lose.

Answer 1

I'd say because it's a volkswagon...seriously, what about the alternator have you tried that? or checking your spark plugs. You'll probably need all new hubcaps as well.

Answer 2

you need three things to get your diesel going,compression,fuel and hot glowplugs reckeck your timing belt marks will eliminate the compression, use a testlight on the glowplug connectors and check for voltage, even pull one out and see weather it gets red when grounded and key on. diesels require very clean fuel and it must be under pressure so check and replace the fuel filter(try blowing through the old one)still no luck pull an injector out of intake manifold and check spray pattern

Answer 3

older cars always have problems, consult your local car place. The best though is your car's dealership, they know your car better.

Answer 4

i think it could be the glow plugs, its a common fault in them
