This morning did an underhood inspection. Turned truck, on put in neutral, set parking brake to check transmission fluid. Finished inspection. Went back later to drive truck. Truck started for a moment ran very ruff. Now it tries to start but wont turn over. This is my fathers truck(baby). Any and all help or tips would be great? Thank you.
Almost sounds like not gettin gas? Check spark and fuel pressure.

Usually there is a spark or fuel delivery issue when engines idle rough or don't start.
First, pull a plug after trying to start it, if it is wet, you are getting gas. However, it may be too much gas.
The next thing to check is the spark. Clean off the spark plug you pulled to check for gas, it is actually best to buy nesw plugs as if the plug looks black at all it may be gas fouled and will not spark, put the plug into the plug wire boot and ground the threaded area of the plug onto the engine. Don't hold it as it will shock you. Have someone turn the engine over and look for a good blue spark.
If this all checks out, some of the suspect issues to check are; fuel presssure, a dirty or clogged intake tract, a clogged catyltic converter, etc.
Her is a walk through on how to diagnsoe a vehicle that idles rough or won't start.
