Question about 1992 Chevrolet S-10

1 Answer

92 S-10 4.3 ltr seems to be flooding

Was running fine, then during a short trip I noticed a loss of power. Fuel injectors seem to be outputting heavy flow during cranking and rough idling.

    I have 92 GMC Sonoma 2.8 liter V6 that has this same issue....It floods itself out especially when cold outside..The injectors put out high flow rate..also the fuel pump seems to stay on for alonger period as well when this occurs

The fuel pressure regulator may be failing. If your engine code is "W" the regulator is under the upper intake manifold. You may replace the entire injector package or just the regulator.

DORMAN regulator Part # 55162 about $40
ACDELCO CPI injector Part # 2171431 about $400

These parts may last slightly more that a year if you are lucky. I carry an extra regulator and manifold gasket at all times.

When hot will randomly not start unless gas pedal is pressed all the way down. on a 2001 honda crv. replaced fule pump,fuel relay,fuel filter, dist. cap, rotor, coil,plugs, wires, and ignition control


If you hold the pedal to the floor it puts the fuel system into Clear Flood Mode. This prevents the injectors from firing and lets the already present fuel burn out. Now if this has to be done on every short trip you probably have a leaking injector.

Does the vehicle seem to crank slowly or stop and then crank when this happens?

No idea but you could have damaged the gearbox so please ask a local mechanic to have alook for you

Need trouble code list


Older Model Computer Codes (OBDI) - IMPORTANT! Codes may be different for newer vehicles starting circa 1996.
11 No ignition reference signal detected during cranking OR timing belt skipped one or more teeth; OR loss of either camshaft or crankshaft position sensor.
12 Battery or computer recently disconnected
13 MAP sensor or vacuum line may not be working
14 MAP sensor voltage below .16V or over 4.96V
15 No speed/distance sensor signal
16 Loss of battery voltage detected with engine running
17 Engine stays cool too long (bad thermostat or coolant sensor?)
OR
17 (1985 turbo only): knock sensor circuit
21 Oxygen sensor signal doesn't change (stays at 4.3-4.5V). Probably bad oxygen sensor
22 Coolant sensor signal out of range - May have been disconnected to set timing
23 Incoming air temperature sensor may be bad
24 Throttle position sensor over 4.96V
25 Automatic Idle Speed (AIS) motor driver circuit shorted or target idle not reached
26 Peak injector circuit voltage has not been reached (need to check computer signals, voltage reg, injectors)
27 Injector circuit isn't switching when it's told to (TBI)
OR (MPI) injector circuit #1 not switching right
OR (turbo) injector circuit #2 not switching right
OR (all 1990-) injector output driver not responding
- check computer, connections
31 Bad evaporator purge solenoid circuit or driver
32 (1984 only) power loss/limited lamp or circuit
OR
32 EGR gases not working (1988) - check vacuum, valve
OR
32 (1990-92) computer didn't see change in air/'fuel ratio when EGR activated - check valve, vacuum lines, and EGR electrical
33 Air conditioning clutch relay circuit open or shorted (may be in the wide-open-throttle cutoff circuit or normal on early 80's models if you don't have air conditioning)
34 (1984-86) EGR solenoid circuit shorted or open
OR
34 (1987-1991) speed control shorted or open
35 Cooling fan relay circuit open or shorted
OR
35 idle switch motor fault - check connections
36 (turbo only) Wastegate control circuit open or shorted
37 Shift indicator light failure, 5-speed
OR
part throttle lock/unlock solenoid driver circuit (87-89)
OR
solenoid coil circuit (85-87 Turbo only)
OR
Trans temperature sensor voltage low (1995 and on)
41 Alternator field control circuit open or shorted
42 Automatic shutdown relay circuit open or shorted
OR
42 Fuel pump relay control circuit
OR
42 Fuel level unit - no change over miles
OR
42 Z1 voltage missing when autoshutdown circuit energized (The Z1 voltage is the voltage of the circuits fed by the autoshutdown relay. This typically includes fuel pump and switched-battery feed to the ignition coil)
43 Peak primary coil current not achieved with max dwell time
OR
43 Cylinder misfire
OR
43 Problem in power module to logic module interface
44 No FJ2 voltage present at logic board
OR
44 Logic module self-diagnostics indicate problem
OR
44 Battery temperature out of range
45 Turbo boost limit exceeded (engine was shut down by logic module)
46 Battery voltage too high during charging or charging system voltage too low
47 Battery voltage too low and alternator output too low
51 Oxygen sensor stuck at lean position (this may be tripped by a bad MAP sensor system causing a rich condition. If you get hot rough idle and stalling, especially on deceleration, accompanied by flooded engine and difficulty restarting, that can be a bad MAP sensor causing the O2 sensor to try to compensate. If you get poor cold driveability, stumbling and bucking, and acceptable warm driving with poor gas mileage (a drop of 10 mpg or more), that is usually the O2 sensor.
OR
51 Internal logic module fault ('84 turbo only).
52 Oxygen sensor stuck at rich position
OR
52 Internal logic module fault ('84 turbo only)
53 Logic module internal problem
54 No sync pickup signal during engine rotation (turbo only)
OR
54 Internal logic module fault ('84 turbo only) - or camshaft sensor/distributor timing
55 End of codes
61 "Baro" sensor open or shorted
62 EMR mileage cannot be stored in EEPROM
62 PCM failure SRI mile not stored
63 Controller cannot write to EEPROM
64 Catalytic converter efficiency failure
65 Power steering switch failure
66 No CCD Message From TCM and/or No CCD Message From BCM

My 2004 saturn ion is hard starting you have to depress gas pedal to flor and when it starts very idle very slow seems like it flooding with large of engine power


clean the throttle body also pull the vacuum line from the pressure regulator and see if fuel drips out if so the regulator is bad

My 1991 toyota 4runner keeps blowing the efi fuse and my engine floods gas. what could be the problem?


Check the EFI main relay, the circuit opening relay, and the fuel pump relay. Inside the fuel pump relay there is a switch controlled by a coil. During start, the fuel pump gets full power for a couple of seconds to build up pressure. Once pressure is good, the fuel pump relay is supposed to switch (via the coil) the fuel pump to reduced power. If the coil in the relay is bad, the reduced power setting is not available and the fuel pump will run at full power all the time. At this heavy current draw, it won't be long until the EFI fuse blows. This would also give more pressure than is necessary to the cold start fuel injector which runs on a timer. This extra pressure during the time that the cold start injector is operating may be the reason the engine is flooding with fuel.

SOUND LIKE A INTAKE MANIFOLD LEAK.WHICH WILL CAUSE BACK FIRING.FUEL INJECTORS COULD BE STUCK OPEN DUE TO CARBON BUILT UP ON INSIDE OF THE TIPS.TRYING CLEANING INJECTORS ADDING A BOTTLE OF FUEL INJECTOR CLEANER IN A FULL GAS TANK.ONCE YOU GET ENGINE STARTED DRIVE TRUCK AROUND TO LET THE INJECTOR CLEANER CLEAN INJECTORS.IF THIS DONT WORK.YOU COULD HAVE A BAD INJECTOR STAYING OPEN.HAVE TO BE REPLACED.

1998 nissian altima engine floods at random


gosh, nissan spent 6 million dollars replacing faulty/leaking fuel injectors around that time ...maybe its worth a trip down to the dealer and do a campaign/recall search on your car...might be a car that was covered under that campaign and you might get injectors covered
