1995 gmc k1500

Asked by Sep 19, 2016 at 12:12 AM about the 1995 GMC Sierra 1500

Question type: Maintenance & Repair

My 1995 gmc 1500, 350 tbi 5.7 v8 runs perfect. But
when i first start it, even when its warmed up,
sounds like its trying to flood itself. When i first start
it, i have to push the gas all the way to the floor and
then let off when she fires up, but for the first 30
seconds, if i give it too much gas, it trys to stall, if i
barely give it gas, its runs fine. After that 30
seconds, she runs like a top, any ideas why its
doing this?

Pushing the gas pedal all the way to the floor sets a "clear flood" mode, the engine will crank but no fuel is delivered, giving engine a chance to clear up flooded fuel condition. Maybe check for DTCs, a stuck injector, fouled plugs, low fuel pressure (needs to be 55-60psi min to open poppets), bad/weak spark, etc.

Check PID for coolant sensor when cold. If it say below zero computer will give too much fuel.
