Chevrolet Repair: ct1500 injector problem, coolant temp, fuel sprays

Question
hi Tom,first I wanna say Thank You!I did what you told me on my 1990 G20 with the idle problem on the map sensor,I replaced it,and it's been running great since then.I have a 1991 1500 ext cab 4x4 5.7L.It stopped delivering fuel to the TBI.I put in a new fuel pump and fuel filter.tried to crank it.fuel sprays a good spray pattern but sprays TOO much fuel.as if I am holding the throttle down 'wide open'. therefore filling the throttle body with gas quickly and flooding it out.I tried tapping around on the injectors and the throttle body but there was no change.It ran pretty good before it first stopped getting fuel about a month ago. Thanks!   Trent

Answer
HI TRENT,TRY TO RESET THE PCM. REMOVE BATTERY CABLE + OR - FOR 20 MINUTES. RECONNECT AND SEE IF PROBLEM IS STILL PRESENT. IF PROBLEM IS STILL THERE THIS SOUNDS LIKE INJECTORS ARE STUCK  WIDE OPEN.  REMOVE THE HARNESS PLUG FOR THE INJECTORS AND CRANK IT OVER LIKE THIS AND SEE IF THE FUEL STOPS LIKE THIS,IF NOT INJECTORS ARE STUCK OPEN. [RARE] SO IF THEY DID CLOSE AND THIS DID STOP THE FUEL FROM RUNNING INTO THE TB THIS SOUNDS LIKE A PCM FAILURE [HOLDING THE INJ WIDE OPEN OR COOLANT TEMP SENSOR IS LIKE STUCK -30 DEGREES..WHICH I HAVE SEEN FROM TIME TO TIME BUT AGAIN VERY RARE..IF YOU FEEL THE PCM IS AT FAULT GET A SCAN TOOL AND SEE WHAT KIND OF DATA IT IS SHOWING YOU AND ALSO CK FOR ANY CODES AS WELL. YOU DID NOT TRY TO JUMP START THIS AND HOOK THE CABLES UP WRONG DID YOU ???? JUST ASKING...LET ME KNOW HOW THIS WORKS OUT FOR YOU,,,TOM..
