SR20 AAC valve / cold start fault

Recommended Posts

what voltage readings should i be getting at the plug for the AAC valve at cold start?

 

problem is hard cold starting. takes ages to crank, opening throttle slightly makes it start. want to test the signal voltages before i remove the top half of the plenum to get to the valve block.

Try replacing the injector o rings too, as it often shows the same sort of cold start symptoms when they are leaky.
