No start, when cranking motor....
 
This morning I went to start the 93 1500 350 motor, no go..Just cranks, where should I start first?? I'm not looking forward to replacing the fuel pump in this heat..Any suggestions, Thanks..

Check your basics. Do you have spark at the plug, Is there fuel? If it drove and you parked it and the next morning it was doing that I would tend to think it is ignition model in the HEI distributor.

Bill nailed it - most likely a failed fuel pump, or bad ignition module.

Pop the air cleaner lid and spray a solid huff of carb cleaner down the throttle body and see if it tries to start now. If it does, you have a fuel delivery issue. If no change, proceed to check spark.

I've run into a bad oil pressure switch crank/no start with the 6.5TD. Do the gas models have one of those?

I hear buzzing in the tank when ignition is on, but I changed the fuel pump relay last week, started up all week, went to work, then again today same thing all over again..
