OK, a compression test will be next. I can also do a leakdown test if you think one is better than the other. Have never done either but have researched it and think I can probably figure it out. Do you think that should be done before a voltage firing test? I have not touched the valves during this episode. Checking my records just now, I see that they are due for adjustment now. I have not checked for flat cam lobes and would need advice on how that's done. The engine has fewer than 25,000 miles on it. Could the camshaft be damaged? Also, what did you make of the fuel pump reading 4.5 pressure but not going back to zero when the engine is shut off? Does that indicate a problem?
