Vehicle not used 5 days. Then would not start. Turns over, Gian spark from coil. Fuel pump pressure tested at 55 PSI. Weird thing, engine tries to run a couple turns 'after' I stop cranking. Has fuel smell.
Fuel pressure is a little low. Will it start with a couple shots of carb spray in the throttle body? If it does and continues to run than the fuel pump is not providing enough pressure to to open the mechanical poppet valves on the end of the injectors. minimum fuel pressure is 58 psi. One PSI below spec is enough to make it not start.
Also check to make sure there is spark at each cylinder. just because there is spark at the ignition coil does not mean it is getting the the spark plugs. you may have a bad cap or a rotor that is burned through.

Could be as simple as your fuel filter...after the truck starts..can you keep it runing by gunning the motor?
If you can feather the accelerator to keep the motor runing, I'd start at the filter, and then check the fuel pump

If the pressure is slow to rise, you should consider changing the fuel filter if it has not been done in the past 30,000 miles.
Next, disconnect a spark plug and check for spark while engine is cranking. Use a spark tester or old spark plug grounded to the engine block.
Let me know.

It sounds like you have a pin hole in the hose that goes to the fuel pump in the gas tank. The pump is mounted on springs and it is common for the plastic hose to get a hole rubbed in it from one of the springs. This usually cause the vehicle to be real hard to get started when it is cold.

Ended up being the distributor. Clogged fill of corrosion. Replaced entire unit
Perfect.
