I've reached the end of my diagnostic rope for my 'new to me' 2002 V6 GLX 4mo wagon just will not start!
The car started and drove the first 30 miles or so of the trip home. Conked out on the highway, has not restarted since.

Fuel starved? I can 'light the engine' with starter fluid/ether.

-------------------------------------------------------------------------------

New plugs installed, engine lights with hot shot/ether
Fuses 28 and 29 good
Fuel pump relay good
New fuel pump installed...Pump runs when DC current applied directly
to pins 2 and 4
Test bulb connected to pins 2 and 4 of fuel pump harness 'LIGHTS UP'
ESS FAILS the resistance test - No resistance between Pins 2 and 3
** New ESS also fails the resistance test ** The old one is still in the car


I would like a recommendation for a known good' VW diagnostician in my area. Onsite is preferred, but will have the car
towed if I have to.

Hoping to actually use this car at some point!

TIA
Jack

You replaced the plugs but misfires may come from bad coil packs. So it seems you're on your way to replace all the coils, both O2 sensors and the MAF sensor before any other serious further actions.

Don't forget that it's a V6.

Wouldn't bad coil packs in V6 cause misfires?
Yes, but it's kinda rare. In this case, it's 3,4, 6 misfiring and random misfire. Random misfires tend to point away from coil pack issues and go towards air/fuel ratio problems..

I have a new ignition coil...I'll install it, clear the codes and try again. The plugs are new.

It points to a maf reading that is out of range. It can a bad MAF, nicked/corroded wiring, or even a bad ground.

Thanks and blessings to all that have been helping me here.


Cleared and re-ran VCDS-Lite auto-scan...https://www.dropbox.com/pri/get/Public/02%20GLX_2.pdf?_subject_uid=63042105&w=AAD306RfSimG-A7c9B7BYJCWlFR_GlHjhLHbS5FbSQhl4Q

Status...No change...No noise from fuel pump except when DC current directly applied. New filter, plugs, coil pack...PCV hoses cracked and awaiting new.

There is an odd but cyclic clicking noise from the firewall to the right of the radio when the ignition is on. I need to get just that little bit closer.

The long list of original codes was caused by a blown fuse or a fault in the wiring.
The current codes you posted shouldn't prevent starting.

Check all fuses with a meter.
Do a full scan (all modules) and post results.

Definitely leaning toward a wiring fault...I'll be on a bucket reading fuses for the next few hours. My windows no longer moving...though I can hear relays in the doors clicking when I push the buttons.

IIRC there are no relays in the doors.

I suggest you ask a moderator to combine your 2 threads, it is confusing and hard to follow.
