2000 Chevy 3500 5.7 Lt vortec pickup cranks but won't start w/o fluid

I had the same problem with my 88 ram, turns out it was the hall effect sensor in the distributor. Im not sure if you have one in that model but its always a start. Of course, the computer also runs the injectors via the coolant temp sensor. If the engine is cold, the computer puts more fuel into the engine to start it. Now.. if you have a failing coolant temp sensor, the engine wont be able to tell if its hot or cold, thus resulting in hard starting. Let me know if you fix the issue.

Thank you! I relayed this to my husband as soon as he came home from work. Will definitely let you know the outcome! Thank you again!
