01 yukon Will not start. It turns over good but wont crank. Every once in a while it will crank and the shut back off after a few seconds. Like it just uses the gas in the fuelpump/lines then shuts off. I was thinking it was a relay. But I have changed them.

There are a series of tests for isolating the root cause but I would jump right to a fuel pressure gauge. This truck requires a minimum of 55PSI to run and fuel pumps fail often.
