I have a 73 2 liter that I am near the end of the restoration.
We are trying to get the car to run. The engine is rebuilt, it has a Bosley fuel injection harness. We pulled two injectors and we saw no fuel flow. The fuel pump runs and we have fuel pressure. We then removed the ECU and checked the pin outs on the ECU cable per Paul Andres schematic. One thing we found was the start signal from the ignition switch was 10.5 volts. It should be greater than 12 volts (pin 18 and ground). What could cause the low voltage to the ECU? Thanks, Mike . |

The fuel pump does run. I replaced the ignition switch about 6 years ago when it failed.
I will check fuel pressure. I did clean all the grounds when I pump the engine back in the car. Thanks for the other suggestions. I will try them. I have another question. The new injection harness had the coil wire labels switched. Could that damage the ECU. Thanks, Mike |
