Hi Scott,

You've diagnosed the issue correctly.

Car starts/runs when the blue/green wire at Fuel Pump Relay is jumped to ground.

Barring a pushed out terminal on that wire, that's all you need for a conviction.

No, the 951 will not work. But, if you cannot locate a 572, you can wire a k-jet fuel pump relay to do the safety job that's needed. Here's a map of one such relay. You would ground pins 31 and 87, run a wire from 31b to the ignition coil negative (or the white/red tach wire behind your instrument cluster), run terminal 30 to your blue/green FI relay coil terminal, and splice in ignition-switched battery (avail at the FI relay term 87 or from either orange wire) to term. 15 of your new relay.

A k-jet relay may be harder to find in the yards these days, but FCP has one for $23. p/n 1348600 or 3523637.
