I still think this project car's possessed-the latest dilemma 200

Okay, here's the deal. I went ahead and checked and recleaned all of the grounds like sdewolfe had suggested. I've already checked and rechecked the

distributor setting @ TDC on the #1 cylinder and verified spark. All's good there. I also downloaded that greenbook that you suggested as well. It had all

of these steps of things to check but didn't have what to do if it didn't check out so I went back to the Bentley. First, from the greenbook I found that

I don't have voltage at terminal #18 in the ECU harness connector. The Bentley
says to refer to the wiring diagram and repair the wiring fault. This is where

I'm weak. First, let me say that since this is a project car with an upgraded engine wiring harness I'm using the 1984 model wiring diagram from the Bentley.

I did find the ECU and terminal #18. I went ahead and reconnected the connector to the ECU and performed the system and fuel pump relay tests from

the Bentley starting on page 241-11 for the LH2.0 system. Here's where it gets weird. I did step #1 for both relays (they're identical for the LH2.0) and they

both had voltage at terminal 87. It says that if there's not voltage, go to step #2. I went ahead and checked step #2 anyway and the system relay was good

but the pump relay didn't have voltage at terminal #86 with the ignition off. It said once again to fix the wiring fault. So I went to the wiring diagram and

found that the wire from the fuel pump relay terminal #86 goes directly to the terminal #18 on the ECU plug. Also it's fed voltage from the #13 fuse in the

fusebox which is supposed to have voltage with the ignition off. I went to the fusebox and checked for voltage and there isn't voltage with the ignition off

but there is with it on. Still no-start. I've looked at this thing and I don't know what to do next. Any ideas? Thanks, Charles
