Jetta TDi ran one day and didn't start the next morning

[ExtremeTDI]

My 2000 Jetta TDi ran fine on Friday. I didn't drive the car Saturday and then went to start it on Sunday and now it only cranks. I checked the anti-shutter valve and it wasn't stuck. The glowplug light comes on and then goes off so I would assume the glowplugs are good. I'm thinking I'm not getting fuel. Any other ideas? How can I check my fuel pump?

Thanks

crack the nut where the steel line meets the injector.s do you have fuel sputtering out as you crank?

Yeah what Fase said. I had the same problem. I had to bleed the air from each injector line to get it to start. The root problem was the T-valve on the fuel filter was cracked and letting in a bunch of air. Changed the T valve and I have been good ever since.

Or the internals of the pump went. Happens....

If the IP is fine when you shut if off, then the IP is probably fine the next morning.

I hate to sound like a broken record, but make sure there's no air leak around the thermostatic-T on the fuel filter. Or bypass the T and plug that hole.

Not necessarily. They can fail seal running and stay running but once they are shut off they are impossible to restart.
