[s-cars] Fuel pump photo and relay links

[Fred Munro]

Hi Steve;

Sounds like the problems I had with the Type 44's when the fuel pump check
valve went bad. Hard hot start but it would run if you got it going. I made
up a fuel pressure gauge that bolted to the banjo fitting on the outlet of
the fuel filter to check whether the system would hold pressure after the
fuel pump stopped. At one point I was running two check valves in series on
my '86 5ktq to get the dang things to hold.

I'm not aware of any check valve issues with the UrS cars, but I suppose
anything is possible.

so now with a fresh fuel pump and a new fuel pump relay, we still have
the same no start symptoms. however, we have verified it will run if
it ever gets started.

how did we do that? we tested to see if we had spark (we did) and got
the car sputtering on ether. a second shot allowed it to actually run.
we had the car idling for 30 minutes. I'm pretty sure the ether was
long gone. <g>

still no codes with VAG-COM.

so we've got fuel and the car will run, assuming we can get it
started. why can't we get it started?

it turns over
it runs and appears to make power (will verify tomorrow w/ test drive)
it just won't start (without ether)
replaced fuel pump
replaced fuel pump relay
replaced fuel filter
unplugged MAF (runs better with it plugged in, so it appears to work)
performed SJM output test (everything clicks and wiggles)
tried a different ECU with same results

anything else I might look at?

thanks!
