I have checked the firing it is good. I have changed the crank sensor and still having problems. Fuel presure is 58 pounds. It will crank sometimes and sometimes it want. Any ideas?

Your saying, it cranks good but won't start, when the problem occurs? When the problem occurs can you check B+ and ground at the injector/s, engine cranking? Can you check for codes? Some of the national brand autostores, will check codes, free of charge. If you can trust the vehicle for a round trip?

When the engine want start I can spray a little gas or starting fluid in the intake and it will start up and run for short time and sometime it will run until I turn it off. I'm not sure of what you mean B+ and ground at the injetors?

I mean check for voltage and ground at the injector/s, engine cranking, when it refuses to start. You have that spider fuel system?
