Hard Start after fueling

[Black02Silverado]

Looks like another change of the EVAP. Did the part you replaced be an AC Delco part?

 

At least you don't have to pull the bed like I did to get to it.

 

As for the fuel pump, it will cause hard starting. Best way to find out is do check fuel pressure. I got a loaner gauge from Auto Zone to check mine.

BOught a Dorman part both times (replaced 6 months ago).

 

Dorman 911-032 Vapor Canister Purge Valve

 

I went and filled up and it started fine. Code hasnt come back (yet). Hopefully this thread will help others. The fix is like $20 and maybe 5 mins of work.

Post back after a few fill ups. Hope it works for you.

Your original problem was no start after refueling, my response is the same. Your purge valve is stuck open, weather you've changed it or not before.

Just an opinion, but........

 

When it comes engine metering, I would stick with stock components that were labeled Delco, Delphi, or GM - only.

 

Some of us had to learn the hard way.

I have had good luck with Dorman parts in the past, we will see how this one goes

 

Truck ran flawless today and it hasnt the past few wks.

I had those symptoms once. I got a load of water in the gas from an unfamiliar station. I had to have the tank pumped out.

Pump the tank out I had some water in the fuel I hit a water puddle about a year ago but I don’t think it’s from that I thought it was for maybe a gas station kind of the same as you I did replace the purge valve solenoid yesterday and it fired right up I’m still getting a lien code or bank to downstream O2 sensor but I just replaced it may be bad part I may be a short in the wire for the roof I bought some fuel out of the where the fuel filter is into a glass jar 

found so water in fuel I ordered the oil catch can
