My CEL comes on and will stay on until I turn the car off. Sometimes it comes back, sometimes it doesn't. Anyways, I pulled the code and got a code 43(fuel supply system). What is causing this?!?!

 

What else is your car doing besides giving you that CEL, we need more information...

 

It runs pretty good really. It's been laying down a cloud of smoke latley. I don't know whether it's unburn fuel or oil. I just checked the compression and it's still good. Need to do a leakdown test. But I want to know why this code popped up. Oh yea, and that code 21 was an old issue that has been fixed. Anyway's.... yea.

 

Could it be from my FPR?

 

What color is the smoke?

 

Check the vacuum hose on your FPR.

 

Need imput.
