Yes, spark, fuel, and compression will give you a running engine, It is also required for all to occur at a certain time. I do believe that you would hear a backfire thru the exhaust system if the exhaust valves were not fully closed.
The test for the VCT seems pretty straight forward.
With the ignition off, unplug the wiring harness from the sensor.
Check the harness for continuity and shorts to ground. Repair as needed.
Reattach to the sensor.
Using a digital volt ohmmeter on the resistance setting, probe the terminals.
Resistance should be between 3.0 and 6.0 ohms. If not it is bad.
Not something I would want to change needlessly.
Will the engine restart?
How does it run until it stalls?
Are the plugs wet, black, or white and dry after it stalls?
Some other things to check.
A compression test.
Fuel pressure. Even low pressure will affect performance, starting, etc.
Leaky or clogged fuel injectors.
The O2, CTS, IAT, and TPS can have an effect on performance and starting. A good scanner will show performance related issues for these units vey quickly.
Some DIS systems do have ignition modules. Yours does not. My mistake. :Oops:
Good hunting and let us know what you find. :)
