Paul, you need to have good ignition before the fuel relay will pull in. The LH2.0 and LH2.2 fuel ECUs both need to see cranking or running ignition pulses to ground the relay. With LH2.4, the program re-incorporated the initial buzz that was a byproduct of the K-jet relay design, but it serves no "priming" purpose. It was just deemed such a useful troubleshooting clue, and it certainly does no harm. Except that a great myth developed around it.

You might try Lucid's method for checking the Hall sensor and the ultimate generation of spark (and the fuel relay engagement). Use a feeler gauge to substitute for the vane in the distributor to cause a spark.

Edit: Another simple check, after you confirm the t-belt is turning the cam: try to get it to catch with starting fluid to verify spark. If that works, then chase the fuel system problem.
