the problem is pretty straight and forward, mm drove the truck and another potential problem arose (i think there's a correlation here) but she noticed and now i noticed when the trucks is started there is like a burnt gas type smell, i notice it more when i turn the truck off and its only outside. moms bf says it smells more like burnt oil.
whats causing this?

Maybe oil is leaking on the pipes or something, hard to say.

I doubt you're smelling burnt gas. Gas burns pretty quick and pretty clean, particularly compared to oil.

For you to smell oil burning, there's a leak somewhere and it's getting close to or is coming into contact with some part of your exhaust.

Have a look yourself at the exhaust up under the front of your truck and at the back of the engine for any dark or discolored wet spots.

Probably valve stem seals.

Ima change status, it smells like i hit a skunk when i kill the motor, buddy thinks its a cat, not sure since theres no code, unless this is just the start an a code will eventually come on

Carcrazygts2

if it smells like rotten eggs its a cat on its way to being plugged.

Jefk

ima wait ona code to verify that, what could it be if it smells like oil

Jefk

im ignoring that cats until a code comes on(Then hi-flows if it does haha) i pooped the oil cap and it smeels llike gas AND oil, the dipstick smells normal though. And when i rev the rpms the exhaust smells like old gas in my opinion( last time i use walmart maybe)

Jefk

I concluded its just the cold weather, its gone mow that its above freezing and whAt not, however, i figured out my fuel pressure is low, my uncle says its the one way valve in the fuel pump, can anyone back that up?

How about natural gas, does it smell like that? Like a skunk might be close enough.

Check your fuel/vapor lines. Emission lines. The main line starts at the firewall, runs down to the frame rail (drivers side), then to the back. You can also smoke test that line.
