Truck died on the highway, 0 reading from contacts in distributor cap via ohmmeter/multi, no spark coming from new ignition coil. Replaced rotor, cap, ignition wire. Noticed that the car sparks only when I quickly go from key turn to full off.

Next troubleshooting I'm thinking is igniter or looking for a blown fuse somewhere, or it's shorting out. Any thoughts?

 

Check timming chain.pop the valve cover and make sure its still there.

 

humm what do you mean from on and off. will it will fire once from coil or a given spark plug you choose

if the timing chain is busted and you have this issue. it will sound like **** wail cranking and the valves are bent, and if so damage has been done already

 

I'll check that. Tested coil again tonight with Multi.. Within tolerances but I can hear sloshing if I shake it... Shouldn't hear sloshing right? Praying to god it isn't the Ignitor... $230.

I don't think it's timing chain. Cranked it while trying to jump start last night, just not firing. Sounds normal.

 

Possible voltage regulator?
