Jimmy wont start sometimes

Do you have the 4.3L engine with spider fuel system? That system is noted for problems. Key on engine off, fuel pressure, 60--66 psi, use a fuel pressure gage. It needs that pressure to start, after it starts, it will run with less pressure.
There could be other issues? Engine cranking, you have spark at the plugs and fuel injector pulse?

Ran out of gas on a 1997 gmc jimmy and 4 days later it just cut off and than it won,t crank I let it sit for a minute and than it crank but it happen again. What to do?

Cranking and fuel issues are two separate things. Check age of battery and voltage across terminals. Does it always crank as long as you hold the key but not start? If cranking okey,check fuel pressure,key -on,cranking,or if it does start. Check battery cables for corrosion,also inside cables. Do,a voltage drop test on both cables.. Need a meter or just have a shop pick it up and take care of it.

Replaced multi port injectors,new timeing chain

Ensure the battery cable are not damaged and are tightly connected. Sometimes the cable ends become loose due to corrosion and wear thin.
Also try replacing the Mass Air Flow Sensor, it's the switch looking thing, to the right of the air filter box; I think it runs about $6-$10s. Good luck.

Engine cranks, won't start. Three days later, it starts???

probaly a fuel pump its common for vehicles to do that the best thing to do next is a fuel pressure check to verifiy its the pump

Hard start when cold/first start in morning

The pressure relief valve is in the spider fuel injector not the fuel pump. We have had our 94 gmc jimmy for 4 years & have had to replace the fuel injector 4 times which cost right at $500 each time for the part. Yes the spider fuel injector cost averages around $500.

92 gmc jimmy

I'm not sure of vin? My info shows oil pressure switch in parallel with fuel pump relay, so if that switch is functional and has voltage, once you crank it enough to bring up oil pressure, the pump should run even without the relay. The voltage for load side of relay and oil pressure switch comes from ecm B fuse. The voltage for control side of fuel pump relay comes from pcm.
Any other issues besides fuel? Engine cranking do you have spark at the plugs and fuel injector pulse? If your missing the last two, have to check for rpm signal.
