Re: 1998 suburban won’t stay running

We tried two different scanners and they wouldn’t link up, I had 62 psi when we did the initial check and that is in spec. But from what I remember the fuel relay is only used to start the car and the the fuel pumps power come from some where else and I believe it’s the oil sending or something so if it loses oil pressure it shuts the fuel off. So yes it gets fuel on initial crank but then loses it like it is being told to do so. Just checking to see if anyone else has had a problem like this in the past since I can’t get data from the pcm. I might have to jump a plug under the hood to see if I can get anything from the computer
