My 1999 vw jetta TDI has been giving me prolems starting. It rolls over but won't stay running like there is not enough gas getting to it. I hold the gas pedal down and it sputters but won't stay running. I've changed the glow plugs, got a new battery. I'll donate if you can give me a fix that works. :-)

Thanks Dan

Hello,

It sounds like an issue with the diesel injection pump.
It is possible that the pump has malfunctioned and not providing adequate fuel in order for the engine to run.

I have included the testing procedure below.

Please let me know if you have any questions.
Thank you.
