1999 C2500 Suburban 5.7
106,000 miles
I had an issue one day where I came out of the store and went to start the truck. It would turn over but would not start. I know it had less than 1/4 tank but didn’t think I was out. Gas was my next stop on the way home. I ended up getting my dad to bring gas. Poured in maybe 3 gallons of gas and the truck started up. I went to the gas station and filled it up.
A few days later I head to work. The truck ran for 10 minutes and then died in the parking lot when I was getting coffee. After 20 minutes of sitting I was able to start it and rushed to get it back home.
I already had a new Delphi fuel pump so I figured it was time. Pulled the tank, replaced the pump, installed, and started the truck no problem. Drove home with no problems at all.
The next day I grabbed my trailer and was heading to my shop to do some work. I made it up a very gradual incline and over the hill. When I got to the bottom and applied more throttle I was pretty stumped when the truck didn’t make a noise. I coasted for maybe 1/2 mile and eventually pulled over. 10 minutes of waiting I was able to get it to start (stumbled and then started).
So what is the most logical option. I have gone from is it just a relay (have not done that yet), to fuel pressure regulator, to bad poppet injectors. What is the most logical reason for my issues and what should I be testing?
