351 WITH LOW COMPRESSION ON ALL CYLINDERS

My 1996 Bronco suddenly died on me as I was coming up the hill to my house. It kind of sputterd and slowly died. At first I thought I had run out of gas because I was low but I put in a couple gallons and still no luck.

Spark is good, fuel is good, compression is way low though. 1: 85 2: 80; and the rest range from 75 all the way down to 55.

Never had any smoke or any power issues but it did seem to suck a lot of gas though. But I have a tow hitch and ski racks and I was getting about 9 miles to the gallon.

Any ideas on where to start? Appreciate any help.

When was the last time you changed your fuel filter?

If the timing chain is worn and skipped a tooth, that could do it. The intake valves would be closing way late, resulting in low compression...
