I have tried to diagnose the situation, diagnosing this issue.
What have you done and what were the results of each step?
The cold start valve has been rebuilt too, but however is not connected as I believe it is not atomising fuel well enough
Why do you believe that?
I would like to find out the best steps going forward, and maybe if I have missed anything in diagnosing this issue.
Let's work with facts.
First, create some known facts.
- Set the fuel injection linkages to base level using the procedure on this site, so you know it is good.
- I believe there is a process to set the injection pump to a base setup? You need to know it's set right.
- Others can recommend some other things to set to a known good baseline. Maybe adjusting valves? I don't know what else to adjust to factory spec.
Next, collect some facts.
- Read the spark plugs to see how rich the engine is running.
- Measure the fuel flow rate produced by the electric fuel pump.
- Also, measure the fuel pressure.
- Confirm if the cold start valve has a leak, contributing to rich condition.
- Confirm the spray pattern, a working csv should help starting without touching accelerator pedal.
- Ensure the csv is activated for the proper time duration and stops.
- Confirm when the airflow starts or stops in the WRD.
- Is the barometric compensator letting air in?
What else can we recommend for fact gathering to understand the current status of the car?
Travis - let us know what you learn from this and other recommendations and the group will help through troubleshooting.
