Default 92 blazer TBI floods, dies

Engine starts normally and can be drive when cold but then as it warms up the two TBI injectors stop cycling and just pump continuously until it floods and dies. It cannot be started again until it is cold again. The engine service light is on and retrieved codes "flash test" are 15 Coolant Temperature sensor (low temp) and 16 which I cannot find. I used to own a Jeep Cherokee that had a simialar problem and that turned out to be the Crankshaft Position Sensor. Anybody else run into this? Thanks, Ken

your sensors sound like there going nuts when was the thermastat last changed? another thing is if your sensors sense the engine is running to lean they will start dumping fuel also when its cold even when its hot it will do this, your crankshaft positioning sensor can cause this to mine is going out poppin a code here and there but turning itself off but when the light comes on it dumps fuel and i can smell it till i turn it off let it sit for a lil bit then it resests its self from experience and its back to normal im replacing mine soon.

Code 15 - Coolant temperature sensor signal indicates a temperature colder than -27° F for 30 seconds after the engine has been running for at least 30 seconds.

I'd replace the ECT first as this will cause it to run rich. About the CKP sensor... I'm not really sure that a TBI motor has a CKP sensor as it has nothing to fire sequentially...
