ok before any thing you are not providing the year or engine size for your car, don't be worry i will try to help but you are not the only one not providing this very important information in order to get you the closes answer posible,
the first thing i will recomend you is to contact the dealer and ask for a list of recalls for this gmc, recalls are coming problems that dealers have to repair for free see if you gmc falls into this recalls and have it repair other than that the only thing i will sugest is to pull codes with an scan tool thats only if your check engine light come on, and see if the coolant sensor is bad and have it replace

Check the pickup in the distributor as this is the cam sensor. The injectors run of the pulses created while the rotor is turning around. It should be a plastic disk located under the rotor button.

Try putting 2 quarts more oil in as sometimes the pick up pipe for the injector oil pump can draw in air cos of cracking .if it works then its crossmember and oil pan off time the rest will be plain to a good tech.
Also the rail oil pressure sensor can go funny - find the big plug and socket of wires by the dipstick handle ,going into the engine they are all pink but on the other side of the plug and socket is one wire that was white might be a bit yellow now - pull that out and try for start - fools the ECU into thinking that oil pressure is ok to fire the injectors .If it runs then its new sensor time .

Wow, if my guess is right, that probably has one of the last of the 500 inch engines. I expect it's the same ECU as the Corvettes had, just has a different response curve using a different EPROM. The EPROM usually doesn't go bad and can therefore be transferred into another ECU. If you can find a Corvette ECU that's a physical match, you should be able to plug in your EPROM and be good to go. The junkyards may have books to tell what will actually cross, if they have any to go back that far. But are you sure the ECU is at fault? What indications do you have?

sounds to me like a bad fuel pressure regulator. I would replace that and see what happens, if that fails you may have contaminated fuel
