You have to have the MAF connected and working. It senses the air ratio before if it burned and fuel air is further modified by the Air/Fuel sensor in the exhaust before the catalytic converter.
The mass air flow (MAF) sensor, part of your vehicle's electronic fuel injection system, is responsible for calculating the total amount of air entering the engine. ... This causes the engine computer to miscalculate the amount of injected fuel, causing additional damage to your engine.May 1, 2020
How do you know it floods? Fuel injected vehicles should not over fuel the engine unless an injector/fuel pressure regulator is leaking internally or the computer commands a high injector pulse rate based on sensor information. Does it have spark and fuel pressure when the no start condition presents itself?
double posted, and fluids? you mean FLOODS. see previous post, there are other ways to flood any motor. one other is (iSC /IAC devices are stuck closed) gummed up. this cause no starting air, no air means flooding. I cant see your car, and see if starting with 10% throttle solves the flood, but you can. also WOT cranking, cuts all fueling and can not flood and will start any flooded engine. but if this still floods,now, that is bad injectors. leaking. WOT cuts injection pulses dead, and no fuel flows, cranking. knowing these facts on EFI makes finding causes easy.
I'm assuming the engine cranks with the starter but does not start and run.
check the operation of the cold start injector. This is a separate fuel injector that injects fuel into the intake manifold to help richen up the mixture for cold starts. It operates on a timer that is linked to a sensor that measures engine coolant temperature. Once warm or the timer runs out, the cold start injector is turned off. Other things to check:
Fuel pressure too high (floods engine through cold start injector), engine coolant temp sensor or intake air temp sensor is stuck at full hot (doesn't allow enough fuel for cold starts), fuel injectors are leaking (floods engine with fuel).
Generally, the first thing to check with an engine that floods on warm start is the water temperature sensor that talks to the fuel injection system. The only way the fuel injection system knows how much fuel to supply right after startup is by checking the water temperature. If the sensor says the water is cold, the fuel injection system will supply a lot of fuel. If the reading is in the valid range (just inaccurate) the computer will not recognize that the sensor is bad.
There are other possible problems, but this is where I would start. Someone needs to measure the resistance across this sensor and compare it to a chart in the manual to see if the resistance is correct for the current temperature that the sensor is seeing.
mcdevito75 here, It"s possible but not to the extent the old carbureted engines would flood, Best bet is ti look for a sale some shops run on checking the fuel system, Sears, Pepboys etc.
When starting any fuel injected vehicle you DO NOT need to press the gas peddle. Once the ignition is turned on the fuel pump energizes and fuel is injected into the intake.
Yes there is ,press the accel pedal down all the way and hold it there while cranking ,this will put the ECU in clear flood mode and it will stop injecting fuel .Don't crank it for too long as you ma damage the starter motor .
Your fuel injection pressure is probably leaking down causing gasoline
to leak into the cylinders and resulting in a hard hot starting
condition due to "flooding" of the engine. Try holding the accelerator
pedal all the way to the floor of the car like your trying to go
maximum speed down the highway and crank the engine for 10 seconds or
less at a time. That tells your computer to enter the "clear flood"
mode and stop injecting gas into the engine. Ask your repair shop to
measure the fuel pressure and see if the pressure is bleeding off too
rapidly.
