The engine will not start, it has good fuel pressure and it has spark. Engine will start with either.
Do you

Check fuel pressure with a gauge auto parts rent it should be 60-66 psi

That was the first step taken. The fuel psi is 65. It does have spark. I can get it to start with Ether then it dies out.

Check to see if its a timing chain that jumped. Have checked fuses under hood?

Timing already been checked. All fuses also checked. Note: the Initial problem was engine would not start because the fuel pump was bad. Changed pump/screen/ fuel filter. Now as good psi (65) good spark but still will not start. Starts Immediately With Ether and will continue to run if you keep spraying ether.

Check to see if there is play in rotor. There should not be any and the gear may be worn on bottom of distributor. Check to see if the fuel injection spider is bad. On the earlier models it is recommended to replace them.

Is there a way to check the spider and also could all of the injectors gone bad where none of them will inject /spray fuel? Is there a way to manually force fuel through the injectors to unclog them? I had a buddy form work that this exact same thing happened and believe it or not, I replaced the Distributor rotor and it solved the problem. Not here in my case. This has me stumped

There is a balance test to do this, but you need a special machine to do it. Check with a local mechanic to see if he has another way, but most of time they just replace the spider. Also if this is a pancake style cap make sure it is not the cheap one as it will not allow truck to start. Let me know how that works.
