1987 Volvo 760 Cranks will not start

  • 1987 VOLVO 760

Electrical problem
1987 Volvo 760 4 cyl Two Wheel Drive Automatic

1987 Volvo 760 cranks and will not start with the following parameters:

Reference: Volvo wiring Diagram section 3 (39) page 16 & 17 LH-Jetronic 2.2 B230FT
1. Fuel pressure is 38 to 42 PSIG at fuel rail

2. Relay 464 radio interference suppression -
With power (relay energized) on 12.7vdc to the 376 ballast resistor as well to the green leads at the fuel injectors

3. 0.7 ohms from any one of the 4 injector connectors to pin 13 at 217 Control unit
4. Does NOT receive a signal to ground at the injectors for pin 13 to injectors
5. Obviously all the fuel pump fuses are good (good fuel pressure) as well as a satisfactory fuel pump relay as the fuel pumps (both in tank and main pump) are operational.
I would appreciate any suggestions – perhaps the engine control module is defective?

Thank you

Might want to do some testing of the MAF (Mass Airflow Meter) Volvos wont run if it doesnt see air moving through it. Do you have spark and just a lack of injector pulse?
