First, the vehicle
1987 Chevy S-10 blazer, 2.8 liters of throttle body injected FURY, automatic, 188,000 miles
I was coming home from Oxford (near the dells) yesterday after a few hours of four wheeling. Shortly after I get on the freeway I lost all power, then the truck starts to pop/backfire. I figure...hey must of overheated....but the gauge was not even close to being pegged. Waited for half an hour and tried to start...no luck, just a bunch of cranking over. To make a long story short, the sheriff came, called a tow truck while my friend took my four wheeler and trailer back to his place. $450 tow home in a very nice AUTOMATIC international diesel flatbed. Nice rig...
Anywho. When I get home my neighbor was helping me figure out what's wrong with the damn thing. Pulled the air cleaner and watched the injectors: we have fuel. Pulled a plug wire off one of the cylinders....no spark. Pull a wire off the coil....we have spark. Now we are assuming that the timing chain has snapped, and left it at that
My questions to you all
1. Does this sound like a timing chain issue since some cylinders aren't getting spark?
2. If it is...is this motor an interference engine and are my valves royally ****ed? Is it time for a 350 conversion in which I have no money for?
