Engine quit while running ,4.3 Litre v-6 CSFI
Good cranking speed
eng appears to have good spark at spark plugs
fuel pres. seems to be good at fuel connection at top of eng. when key switch turned on ( no test gauge available) CSFI fuel system
I am a 60 year old equip. and diesel mechanic whose knowledge base is old school, points, and carbs
I am on a small island 1000 miles south of Hawaii with very little resources, working for T.N.C. ..(The Nature Conservancy)

What will shut that engine down ( sensors ECM's ), and what would be good parts to order in, that would cover all, as described above.?
Difficult question, I understand........
Thank you,
Bob Gosdin
