I have been advised to try two things. First, attempt a "pop start" or "hill start" by placing car on a hill in second gear and popping the clutch with the engine turning. Second, if the above doesn't work, lift the air flow sensor with key on and bleed the lines. I'm a little leery about lifting the air flow sensor because I would hate to reflood the engine.

I would much appreciate any advice. Beautiful fall driving this weekend if I can get engine to turn!

Many thanks!


Thunderroad,

How were you able to flood the engine by replacing the fuel filter and fuel accumulator? This does not make sense to me and I've been tinkering CIS for awhile. Maybe we could learn something from your experience. Thanks.
