? Gas needle goes to E,then has no power, but tank is full
Yea I know what the F.
I know my tank is full of gas. And it only happenes sometimes. The car starts fine, the needle will go the F, so I drive it down the road and sometimes the needle will then fall (slowly) to E and then the car has no power. It will idle fine but when you try to give it gas it just bogs. But if I slam on the brakes it seems to go back to normal driving the gas needle goes back to F and so on. It has done this about dozen times in the last 6 months. It will do it with a half tank or full it doesn`t matter how much gas is in it.
Any help guys anyone heard of this going on.

is it possible the ECM takes the info from the fuel sending unit?
for example, the ecm takes the info from the fuel sender to determine how much fuel to pump, and since the sender may be bad giving a false reading, when it reads E the ECM thinks its low on gas and pulls back voltage to the pump ..
just a thought since nowadays cars are electrically controlled

that is the problem, when you slam on the brakes the float on the sending unit raises the ecu then thinks "hey everythings peachy" back to green flag racing then the float gets logged with fuel and sinks like a rock
