Spark is good. Tried starting fluid. Engine started and ran good until fluid used up.
Fuel pump good and pumping fuel to TBI. Have swapped out injector and fuel pressure regulator with no effect. Checked injector wires. One wire come straight from fuse, have 12v. That wire also goes to ECM, ohm check good between ECM and injector. Other injector wire goes straight to ECM, also ohm check good. Fuses good.
Noticed liquid oil on part of one ECM connector. ECM is mounted under dash. No evidence of external source of oil. Does ECM have internal oil filled component?
Suspect ECM is bad, but have no fault codes.

Can find no crank sensor or mention of one in the vehicle service manual. Did find mention of a crank input to the ECM. However the wiring diagram shows it to be a voltage straight off a fuse when the ignition is in run. Replacement ECM did fix the problem.
