Did that, seemed to help some but not a lot. It seemed to occasionally get fuel and hit just for a second but not enough to crank. I gave it a very small shot of either and it fired right up and ran great. I'm stumped.

The fuel system has to be losing pressure beause if you start it back to back with just a second or two in between, it always starts but if you give it 10+ minuntes you can hang it up, its going to take a long time to start if it starts at all.

I'm going to hook a fuel pressure gauge to it and let it sit for a while and see what it does. I really don't know..
