Turns over but won't start without ether

[kbm0084]

I have a 2015 GMC 3500 that won't start without spraying ether.  It will turn over, but unless we spray ether it won't start completely.  Took it to Chevy, and they said they fixed it by fixing the fuel switch, and it continues. Plugged it in and no codes show up. Truck has 160,000 on it...

HELP!  ASAP.  TIA.

bad fuel pump, clogged fuel filter...

Will it stay running once it does start?

[kbm0084]

It runs fine.  Never lags.

So if it's losing prime, then maybe it's high pressure relief valve on the rails.

 

Have you tried the primer before starting instead of just resorting to ether?

It damn sure better be gas as a Duramax will lift the heads off the block when glow plugs cycle...
