LH 2.2 ECU not grounding fuel pump relay...

Recently I dropped a rebuilt engine into our 88 spg. Car turns over but no fuel on the rail. The relays for the ecu and fuel pump work fine.
The system relay is feeding power to the the fuel pump relay via post 86 on the fuel pump relay. BUT, the LH ecu is not grounding the relay. Since the ecu is not grounding the relay the pump is not getting power.When I manually ground the relay (post 85) the fuel pump kicks on and I get fuel on the rail.
So my question is....why is the ecu not grounding the fuel pump relay?
The two grounds for the ECU wire loom connector check out fine. Grounds on the engine front
hoist are fine. Ground at the AMM is working.
I don't need this aggravation!
