no 1 cylinder no compression

[huntmd]

Trying to get my 97 5.4 back on the road after setting for two years(out of the country).Would crank fine but wouldnt start.Had no fuel at the rail.Flushed out fuel tank and replaced pump.She started up but ran very rough did a compression check and had nothing on the no 1 cylinder.So is it time for a rebuild.

With zero compression it quite possible a valve has hung open or simply is not opening. A leak down test would confirm. May want to pull valve covers and check "lifters" and cam followers.

Not likely it would work but you could try and flush the motor to try and free up any stuck lifters, valves, tensioners, rings etc... Doubt it would hurt and you would not have much to lose. Other option is to locate issue and repair and/or pull motor and rebuild.
