Volvo Repair: 1987 760 TURBO VOLVO, turbo volvo, fuel pumps
Question-------------------------HELLO REGE, WHAT IS THE BEST WAY TO CHECK THE VOLTAGE ON THE INJECTORS? DO I NEED AN INDUCTIVE VOLTMETER? I LOOKED AT THE WIRING HARNESS AND HAVE NOT FOUND ANY PROBLEMS, ARE THERE SPECIAL AREAS TO LOOK FOR IN THE ENGINE COMPARTMENT OR PASSENGER COMPARTMENT? THANKS AGAIN. J.

Question -
THIS CAR DOES NOT RUN. IT HAS SPARK, BUT NO FUEL. THE FUEL PUMPS ARE RUNNING. I CHECKED THE RADIO SUPRESSION RELAY AND IT WAS NOT CLOSING BUT IT IS NOW. STILL NOT RUNNING. ANY IDEAS? THANKS IN ADVANCE, J.
Answer -
possible bad control unit or problem in the wiring harness.if there is fuel to the injectors and they are not firing this is controlled by the control unit through a power source through some resistors then to the injectors then it sends a variable ground signal to fire the injectors.

Answeryou can check for power to the injectors with a test light.one spot is under the intake near the hermostat housing where the harness runs by the bracket that helps support the intake manifold.inside the harness here the wires are all green and sometimes begine to deteriorate.
