Re: 91 2.3 40 lb fuel rale pressure & no injector signal?
Without the wiring diagram here, I can only comment from memory.
There should be 12 volts DC at one of the injector wires. Probe
one of the prongs on the harness, and touch the meter ground
probe to a solid ground on the engine (or battery if needed).
The voltage will be present with the key in the "on" position.
The noid light (when used) will stay lit up until you crank the motor.
Once you crank the motor, the noid light will flash off.
If you do not have voltage present with the key "ON", then you
need to check fuses and relays (beside the driver door, or the under
hood fuse box).
