You need to check the codes in CM.
But sounds like you have a lack of fuel pressure.
You may want to put a fuel pressure gauge on it and drive it to see what the fuel pressure is as you drive it. Should range between 30-32psi at idle and 40psi at WOT.

 

Okay here's the codes I think it's putting 21, 117, 22

 

172,33 I'm bad at reading flashes

 

It looks that way. You will only have 2 or 3 digit codes, not both.

 

K it's 3 digit codes put a reader to it and it's all bs codes nothing to wory bout however I do have excessive blow by pops my dipstick out a little and blows white smoke out the breather hose throttle responsive any ideas?
New Rhs heads
Larger cam
Edelbrock intake
Exhaust leak at header collector I need to fix as well

 

Sounds like it is time for a compression test.

 

Ya I'll do it this weekend after seeing the blow by its looking like I blew a ring or head gasket I'll keep ya informed

 

Hello! Did you ever figure out the issue? My truck (1992) dies while driving uphill for the first time last week when I was driving. Once I got her to the flats, she ran OK, but the slightest hill would make her sputter. Thanks!
