[s-cars] 92 (early) S4 no start (now not "kinda")

[Steve Powers]

one would think. however...

I found a broken wire in the harness to the crank sensor. it had
broken yet occasionally made contact. intermittent run-no run.

sounded to me (and others) like classic fuel pump symptoms. I bypassed
the FP with results like yours. I replaced the FP. still no worky...

'twas a bitch!

if you have access to a spare sensor it would be worth trying. if not,
it's fielder's choice.

If it wasn't the fuel pump, then the car would run briefly and then shut off when the fuel pump relay was bypassed and 12v was sent to the pump itself, right?  Just like it did with starting fluid.....
