Continuity Test Results, Help to interpret Continuity Test Results Options

[MFejsa]

Need help to interpret results of continuity test results (see attached) and explain what to do next to get my car running right.

Porsche 914 2.0L 1974 (I believe was originally a 1.7L)

My car starts, runs and drives but idles rough and wont rev past 4,000rpm. It hesitates on acceleration. I have changed virtually all components / parts from rebuilt MPS, tested TPS and works, ignition switch, fuel pump, air & cylinder head temp sensor, swapped out ECU to one that was tested to work, and the list goes on.

I am posting my continuity test results with the hope that some may have experienced or had the same results and knows what to look into more deeply or can diagnose.

The test results concluded the following:

1. When testing the ECU power source from main power relay I could not get the 1V voltage difference from the voltage measured at the battery terminal. No difference and remained the same. Voltage at the battery was 12.79 throughout

2. when testing the voltage at start signal from ignition switch the voltage dropped to 9.7V and was not greater than 12V. However, should be greater than 12V.

So, can anyone help, please. I haven't been able to get the car run and drive right since being restored and have run out of options.

Regards

Michael
