Question about 1997 GMC Sierra
Have you tried to start it with your foot on the gas about 30 %. My question is are you sure its not just a issue with maintaining an idle. This would indicate a bad idle air control valve. Unless you have some readings to go on like fuel pressure and data for the maf and various sensors all we can do is guess also. It may be you have a failed computer but without any testing or data its anyones guess.
