I have a 2007 mustang 4.0L. it was running great then one day I parked it overnight and it wouldn't start at all. Cranks until the battery dies. It has a very slow crank when I first turn the key and only cranks fast when I floor the gas pedal (engine flood mode).
I have luck starting it by flooring the gas with it connected to a jumping vehicle. Then cranking the car with the gas floored until it spins VERY fast, then I let off the gas and it starts up very quick. Once it's running its rough for only a second then it runs completely fine.
I've had the codes scanned and there's nothing wrong with them. Things I've found online to fix were the CHT sensor, but the v6s don't have them. The fuel pump, throttle position sensor, crank position sensor.
I have already replaced the fuel filter, and cleaned the TB.
Any ideas on where to start or how to fix this?? Any help is appreciated
