The Passat has croaked again. Best I can tell with no diagnostic tools, there it doesn't have fuel pressure at the fuel rail. Here's how I came to that conclusion . . . It was running fine. Franny drove it to my house. When she started to leave it started then died. Now it sputters a little when you try to start it, but won't run. Seemed to me to be a fuel issue, so with no other way to check it, I removed the fuel pressure regulator and turned the switch on for a second. Nothing happened. Turned it on for several seconds . . . still nothing. Turned it on and got out and looked down into the hole where the regulator used to be . . . There seems to be a little movement in the gas sitting in the bottom of the rail, but there is no way there's enough gas or pressure there to feed the injectors.
I replaced the fuel filter. The old one wasn't stopped up and the new one didn't change anything. I'm thinking it's a bad fuel pump, but they run a little over $400 at the dealer (Justin checked with a friend of his at Al Johnson's in Dalton . . . haven't checked with Villiage yet) and a pump from my FLAPS (Auto Zone) is $299.99. Soooooo, I don't want to "guess" it's the fuel pump, spend a bundle and then find out it's something else.
Also, it seems there are 2 different pumps for a 96 Passat. Do they interechange? Mine is a 2.0 ABA with an automatic transmission if that makes a differance.
Anyone have any words of wisdom for me?
