Still No Start on 940 NA.....update...need help with diagnosis 900

If you have read my previous posts let me update. The car died suddenly, won't catch on, sparks across #1 plug wire, and crank and cam turn fine. Bought a new Fuel Pump Relay but it didn't solve the problem. Distributor is off the cam.

1993 944 NA Rex Regina, 214k Miles

Previous advice was to also check, and swap, the RSR and the A/C Fan relays. Apparently they are similar enough to replace one another in a pinch. I thought I did that, and ruled out another relay failure....BUT turns out I did not. I assumed (don't go there...) that the only two relays behind the fuse block that looked similar must be those two, so in retrospect, I switched the central locking relay with the window relay and guess what? It still won't start. Now I realize: they are elsewhere.

The 740 Haynes book I have is useless. It sounds like they are somewhere in the engine compartment. The car is parked in a lot 30 miles away from here. I want to fix it and get it home.

I tried starting fluid in the air intake and the car sputters and seems to want to catch on when I pump the acclerator pedal (old habit). I was about to change the timing belt (it's overdue) and wonder if it might have jumped a tooth. I figure I can pull the upper timing cover and compare the marks on the belt and the cam gear with the crank at zero.

I ordered a new fuel pump (Regina), fuel pressure regulator, and an RSR/A/C relay, and fuel filter for Saturday delivery. I have them now. I am not excited about the prospect of changing these parts thirty miles from home. I am just about ready to give up and get it towed.

(Sniff! Whimper! The shame and embarassment I will bring upon my family.....)

Where are the AC Fan and RSR relays located? Once I find them and switch out I think that will determine my next step. Please, any suggestions?
