For the original poster I have another suggestion to offer. In the Glasair (IO360 with fuel injection) I start with the mixture off, bring on the boost pump until pressure stabilizes at full value (about 28 PSI in my engine), then shut off the boost pump. When ready to start push mixture full rich. Fuel pressure will go to zero as the fuel primes the engine. Engage starter. Once running, don't forget to lean a bit until ready for run up or takeoff as fuel injection systems are set to run overly rich at idle.
Paid through 2018! How about you?
