I need you to be a bit more specific.

Damion,
Since you asked, I reluctantly will tell you to:
1). Establish that ignition sparks is produced during cranking!!!!! And reproducible.
2). Forget the rest of the
CIS troubleshooting for they would be useless until you confirm this requirement (ignition sparks).
3). Run the
FP and measure the control, system and residual pressures. Record the cold control fuel pressures from start (cold) till it stabilizes and may take 4 or 5 mins. Continue the observation until the cold control fuel pressures becomes the WCP. This is a critical test because these data would be your baseline data for your
WUR.
4). Leave the air mixture screw alone at this point. This is used for fine tuning with a gas analyzer unless someone has disassembled the air metering unit before and you are starting from a rebuild.
5). How did you confirm that you don't have any vacuum/air leak? Not being able to see one does not mean you don't have any!!!! Test and confirm.
Lastly, your
FP should
NOT be running with the ignition switch @ ON position. There is something very wrong with your set-up (electrical). Your understanding of a
WUR is flawed. It is not a check valve unit but rather a pressure regulator device. We could debate and discuss about the literature but let's put it aside and focus on the culprit/s. Keep us posted.
