Looking for a reason why 1 piston burnt down, and the other plug looks pretty white. How would I check this, and if the fuel pressure is low, what do I need to do to get it back? replace fuel pump? Clean smart valves?

Thanks!

Yes, it can cause a lean condition. You can tap a fuel pressure guage into the fuel line....many people have done this. I believe they usually run around 42 psi.

Ya I should have done a little more reading....I will definitley check it. I have a chip out of the piston on the exhause side at the crown. I need to take the motor out and see what the hell happened...
