Hey all - as the title states, first start issues. I can get it to cough/fart/pop and shake, but won't catch idle or rev.
As for distributer, I've checked half dozen times - assumed it was 180 out (flipped and nothing), put back and it will kinda catch. Have played with large timing adjustments (I marked everything when disassembled, to minimize the guesswork - car ran perfect before) and nothing. Giving it throttle won't help. It almost catches immediately after first crank, and then requires a solid 3-4sec of cranking before it starts to sloooooowly catch.
For settings, injector data in config file matches published figures from Pro-M (pro-m injectors). MAF curve was input by Pro-M. Fuel pump kicks on as it should. Battery is brand new and charged. Starter is brand new. All wiring is good/new. Top end is fresh (Eddy heads/intake, mild 210/215 @050 cam). All hoses/pcv is new. Normally I don't like changing this much stuff at once for trouble shooting purposes, but here we are.
I know that getting in the ballpark for timing is key to everything - i've never had these kinds of issues when stabbing a dist (usually get it by the second try), not saying i couldn't continually screw it up, but starting to wonder if I'm missing something else in the start up procedure. Any guidance from those that have done it would be appreciated.
