As was mentioned these things have a lifespan.
If the board is already out why wouldn't you replace them???
PCM is over 25 years old.
Be sure to maintain polarity.
That's what were working toward. We've got to check our local Radio Shack for parts. My previous posting was more or less an update, not a continued cry for help.

May I suggest, the EEC relay powers the FP relay, here's the test for the EEC relay,

<table class="ADVV1-HotlineArchives-Whites" cellpadding="0" cellspacing="0"><tbody><tr><td class="ADVV1-HotlineArchives-LeftRuledRows">
</td> <td class="ADVV1-HotlineArchives-RuledRows"> 1. Go to the Electronic Engine Control (EEC) Relay. Check for battery voltage on the Black/Yellow (BK/YE) wire from the fuse link. Check for battery voltage on the White/Light Blue (W/LB) wire with the key on from the ignition switch. Check the Black (BK) wire for a good ground. If all OK, there should be battery voltage out of the relay on the Red (or possibly Blue fuse link) wire. If there is none, inspect the connections at the relay. If OK, replace the relay and retest.

2. To verify that the EEC relay is the only fault, jump the BK/YE wire to the Red (or Blue) wire. This should power the system up and the truck should start and run.

if pin #22 at EEC is shorted to ground pump will run all the time with key on tan/lt grn. if you disconnect EEC 60 pin and check tan/lt grn for resistance to ground .005 or less good if any continuity to ground check for short to grnd. on pin #22 FP relay control

Update! Turned out to be just a loose connection going to the EEC relay, some more of the PO hacked up wiring. Redid the connection and she's purring again.
