Help.....Before I get mad enough to burn the truck to the ground

[TNLowLyfe]

Hey guys. New to the fullsize world so I am asking for some help. Ive got a 1991 Chevy Silverado Reg Cab Shortbed with a TBI 350 and a 5 speed. Truck was originally a 305 TBI 5 speed. The truck takes off very rough,no power at all, horrible gas mileage, and when your past half throttle it smokes and the smoke comes up through the steering column. I really like the truck but I need to get it reliable seeing that I am starting school in the next month and its a 25 mile drive one way. Thanks so much guys.

Mistype...Motor that is in the truck is a 327 bottom end with 350 heads and TBI intake. The PO put the motor in it before I got it. Any help would be appreciated

well I guess for starters I would start inspecting all that wiring and its gonna suck cause there is a ton. If everything electrical checks out run a fuel pressure test maybe the tbi is getting or dumping to much fuel in flooding out the plugs etc making it run like crap........also with that fire it could had smoke the ecm. Has the truck been scanned yet?

have you had the timing checked? you mentioned backfiring on FB...

 

[Devs93]

could be a timing issue I would start buy having it scanned on a live data scanner and go from there

Yea, from the sounds of it, you are getting way to much fuel. Take the air breather off, and have someone start the truck and look at the spray pattern from the injectors. It should be a nice even fan shape.
