[s-cars] UrS4 no start diagnosis

[chris chambers]

Gentz,

Patient is a 93 UrS4, was running fine with less than a 1/4 tank of fuel.
Come back out ot the car after being parked ~5 minutes and it
wants to start but won't start.

CPS was replaced ~30,000 miles ago, I don't suspect it is bad.

Poured in ~ 4 gallons of gas in case the gauge is off, same symptoms.

Gave it a squirt of starting fluid and it starts, runs and will rev
until it runs out of starting fluid. Give it another squirt and get
the same results.

Suspect I have a failed fuel pump, luckily it died in my driveway
and I have a spare.

Question 1. Is anything I should suspect other than the fuel pump?

Question 2. I've found the fuel pump replacemetn FAQ on audiworld
http://www.elektro.com/~audi/fuelpump/ however I don't understand
exactly how the pump comes out of the basket, reading this CnP

"Reach in, to the fuel tank and either use the VAG tool to loosen (anticlock wise) the fuel pump retaining basket OR unclip the fuel pump from the basket. Remember how everything is oriented. See photo. There are two clips one at 6 oclock and one at 12 oclock. You can only get one arm in the hole so do one clip at a time, eg. back and then front, lifting/twisting the fuel pump a bit, and then the other clip."

Am I simply supposed to wiggle/pull on the 2 tabs that appear to be C shaped (see pic) http://www.elektro.com/~audi/fuelpump/fuelpumpcarrier.jpg

Thanks
Chris
