Crank but no start

[Kennedy]

On the crank no start issue it sounds like injectors are getting tired. 30-45 minutes later it has cooled.

Can you pump the fuel filter priming pump to remove air after the engine/truck has sat for a while (i.e. an hour - overnight)?

This will tell you whether air is able to enter the fuel supply. Jim

I removed the edge afew days before it stoped running. I haven't been able to start it sence 05/22/19 and the priming pump is still as hard as a rock. But I do not have hardly any pressure at the fuel rail shraider valve unless I have my lift pump running.

There should be a slightly negative pressure (vacuum) at the Shrader valve with the engine idling - assuming no lift pump.

The following link will provide information for what are normal pressures/vacuum at the Shrader. https://www.thedieselpage.com/review...elpressure.htm

When I removed my edge (weird problems) I had to reseat some of the pins in the connectors. Apparently they can back out enough to cause your type of problem.

I hate to recommend an ether start, but sometimes that is what it takes. Very sparingly give it a little sniff while someone cranks it and see if it goes. If it goes we are back to injectors...

Or, have a tech with a Tech II look at injection system values (rail pressures, etc) while cranking. Maybe give the connectors another look to verify no more pins are pushed... Jim
