Hello,Customer Thank you for using our service!

The symptoms you describe indicate either valve or ignition timing are off. Disable fuel and ignition systems and perform a compression test. If all 6 cylinders read around 140 psi, check cylinder #1 for spark and injector pulse at TDC.
Note; Using starting fluid may permanently damage your engine
