Pump running, but no fuel to the cylinders.. 700 1988

We have good pressure into the fuel rail, yet the plugs stay dry and we have a no start condition. We bypassed the radio suppressor and still do not have fuel getting into the combustion chambers. We have a good spark. Any ideas what we should try next?
Thanx,
jzger

The ECU controls your fuel, while the ICU controls your spark. Check your ECU connections. If you have a meter, pull one of the injector connections and check for voltage at the connector-end.

However - first check that the injectors are grounded properly. All 4 injectors have a common ground obtained via a screw on the intake-manifold. If this is bad, they wont work. Also, check your engine-harness wiring. The insulation might be bad causing the wires to short each other. The place this normally occurs is under the intake-manifold area where the harness splits up into the injector-wiring, temp-gauge sensor, knock sensor etc. The other location is near the 2 large-grey connectors on passenger side near the A/C dryer.
