96 Passat Fuel Pump

« on: March 01, 2013, 04:03:58 PM »
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?

Are you getting power at the pump?

I would check the power at the pump or jump the fuel pump to see if it is running, also sometimes you can hear the pump though the gas filler

I was going to drop the tank tomorrow and check for power before I went any further . . . but tonight at the cruise-in I was told that there should be an access pannel under the back seat or possibly in the trunk.  Is that true?  Man that would be nice!   ;D  It's an 18 gallon tank and Franny never lets it get below a half tank.  I wasn't looking forward to dropping it.  Sometime tomorrow after the "blizzard" melts away, I'll check it out.

Zen. There is an access under the trunk carpet or rear seat. Check the last relay on your fuse panel. And I think the fuse is number 16 or 18. The relays are bad about deciding to quit one day. I think they are 25.00 at the dealership. Should be a 167 blue one on your car. There are a couple others that will get it running again but some of them are not heavy enough for more than diag. 80 I think is one and a 18? ?
Best of luck.

Thanks Sal!  Somewhere I have a bunch of relays I cleaned out of a 96 Passat GLS exactly like mine at Pull-A-Part.  Well, it wasn't "exactly" like mine.  That one was sitting in a junk yard.  Other than that, they were about the same!   ;D

No power to the pump.  The fuse is blown.  I'm off to the parts store for some spare fuses.  Keeping my fingers crossed that there is nothing wrong other than the fuse . . . but experiance tells me that fuses usually don't blow for no reason.  We'll see.

I replaced the fuse and everything seems to be fine.  Maybe I just got lucky this time!   :o  I think I'll go buy a lottery ticket.   ;D

I'd keep those fuses handy for the time, and save up your pennies, Zen... sometimes when they get some age on them, or the in-tank filter screen gets clogged up, the pumps can draw a lot and heat up, popping fuses.  I think the car was just giving you a warning shot across the bow... mighty considerate if you ask me.   ;)
