cht 4.2 ohms measured at the connector on the intake manifold (white connector on top)
fuel pressure is 40psi when I manually actuate the pump at the dme relay connector, ~30psi residual (after ~20min)
replaced dme relay
I was told the injectors have been serviced.
The car has been sitting for a long time. I replaced a bad breather hose (engine to oil tank) and cleaned tons of black crap from the air flow meter and throttle body. Tracing a vacuum leak I found the charcoal canister is missing. I plugged the large and small vacuum lines coming from the engine.
I'm basing tests and results on Bentley #s and everything passes. I went through the test in the Bentley and no smoking gun.
What am I missing? thanks for your help

Too low, disconnect it for a cold test start. Once warm, it can be connected at the very low resistance value.
