Also a compression test is a good idea but tricky considering the location of the spark plugs. basically centerline of head and about 4.5" down. My best guess is either a stuck,bad valve or injector failure. I suspect the injector for two reasons. one when I removed the plug it was completely torched, and because it was dry. I have experienced spark failure before and when I pulled the plug it was wet. In that case it I had to replace the boot and the 2 pin connector. Please look at the photos and tell me what you think.Well i can not know what torched means, but looking myself yes.
the std, compression gage has long hose and 14mm fitting on the end, to fit any engine, (not 18mm 1940 ford)
injectors swap sure.
i see no photos sorry, ah yes your gallery, yes. off I go to gallery.
in basic engine repair the vacuum gauge and compression tools primary evidence, and frankly one spark out and in the hose and omg 20psi or 0. not 200.
for sure a 5 minute job. yes cops are pain if the boot shreds, sure.
