97 Yukon will turn over but won't start

[DNH]

My 97 Yukon will turn over, but the engine won't catch and start. I suspect it either isn't getting gas or a spark. Could someone please give me some detailed ideas on what to check? I'm not very knowledgable about vehicles, but I can check a few things with some suggestions. Thanks!

when you turn the key on do you hear the fuel pump prime up?

Have you check all your fuses?

Also to check if you have fuel goto the Fuel Injector rail find the place where you can instal a guage to check pressure and bleed push little needle(watch for fuel spray) once done then turn key on then go and see if you got pressure again?
If your good with a person at autozone or try and see if you can borrow one of the dignostic systems to test ya vehicle. Tip the person for letting you use it and and then you will have a place to start as you check your codes
