Engine Mechanical problem
2001 Volkswagen Passat 4 cyl Front Wheel Drive Automatic

i need help my car has been down for 2 years the engine turns over, it has no compression. Here is what I checked out;it has fuel, it has hot enough spark, the timing belt is fine and in time, I replaced the camshaft sensor I took the spark plugs out and saw the pistons move up and down. My wife was driving it when it died, there was no noise or anything, it was just all of a sudden. Would really like some help, thanks, Chris

Check the fuel pressure if its within specs and also if the injectors are pulsing.

It has no compression. I've overlooked this one-Very low engine compression the engine will not start

the fuel system is fine same results: I take this that the fuel pump is producing the correct fuel pressure as mentioned earlier but is the injectors pulsing

Even if the pistons are up and down- could have jumped timing but being park for 2yrs the engine just don't lose compression and jump time.

Give me more info am lil confused here-this engine should fire up if this 3 ingredients compression/fuel and spark are up to par. Something is not right

The car died while driving two years ago. Right after it died I tried starting it did the same thing its doing now. What about the head gasket, if that is bad wouldnt there be oil leaking where its bad?

You have spark and correct fuel pressure, injectors are pulsing-verify the valve and ignition timing this is where we stop-bcuz if its off it will never start even if you have spark and fuel.

Hello,

I though this might be useful to someone.

I have a 2000 Passat 2.8L V6. One night I came home and had to move my car to get ready for the morning. The next morning I went to start it and it would not start. The engine would crank fine but would not start. I kept cranking the engine and it just would not start.
Luckily I had another car to drive so I could have time to work on it. After tracking down ghosts I found out that the compression was low in the cylinders. I tested it dry and wet and the wet brought up the compression so I tried to start it and boom it started.

It seems like the engine floods or the gas is stripping the piston rings causing a lose of compression.

I had confirmed
- Good ignition
- Good fuel pressure
- Low cylinder compression

ADD OIL TO CYLINDERS TO GAIN COMPRESSION
