'98 Z71 sat up for year or so. Charged batt and fire right-up. Run like a champ for about two mins then cut-off. Won't start up now. Plugs are getting spark. Thing it's getting fuel, but have not pressure tested yet. Fuses all look good. Heard about low oil pressure hooked to starting. Don't know how to check that if engine won't start. Please Help

 

You need to see actual fuel pressure. Even if you pulled the line and you see it pumping fuel it could still not have enough pressure. How does the gas smell? It maybe too old to burn. Check to make sure you have BLUE spark.

 

MD,thanks for the info. I'll check pressure, spark, and change fuel this weekend. If all is good what would be the next step?

 

Pull the codes and Im sure it tells what sensor is bad...
