Truck is dead

[zombiediesel]

So driving and truck died won't restart cranks like a champ though. Replaced fuse 22 removed fuel bowl heater repleaced cps. I'm getting 600 Psi from hpop. Fuel is good too. I read somewhere if you remove valve covers that you could see injectors squirting oil if working properly but no squirt. What next btw no smoke on crank and block heaters been plugged in awhile and its been in the 60s-70s here
Thanks

Is there fuel in the bowl? Does the tach move when cranking? Was the fuse actually blown? don't just replace it, actually disconnect the heater so it won't blow again. Check your wiring everywhere including the valve cover gaskets and under valve cover harness. Sometimes wiggling something will get it to act right.
