Was running ok. Removed heads. Machine shop pressure test and surface. Reinstalled with new gasket set. Now no fuel, no spark, no start. Fuel at rail. Injector plugs read 24 volts. Injectors read 14 ohms. Camshaft sensor reads 10 volts. 160 psi all cylinders compression. Timing marks lined up. Knock sensors plugged up or unplugged (no change). Camshaft sensor plugged up or unplugged (no change). Any ideas at all would be greatly appreciated.
