Ford Excurtion will start normal, but stall when putting in gear (reverse) or braking. When re-starting it runns ok until next braking.

gear, is this a Manual trans? or AUTO you said gear.
what gear, please name the gear, 1,2,3,4,5 R
or PRNDL ( a/t box auto matic) what shift lever selection?
what is out door air temp, you do know brakes can get wet and freeze right?
it wont go you meant? until brakes are touched, key word won't?

ok engine only starts in PRNDL set to N??
is that it?
and then when you shift to D, the car will not move
what about the other gears.? try them all yet?

my guess (wild) is that you dont know how park lock out works.?
that you must hold the brake pedal down to shift to park or neutral.
is that it? (read operators guide?)

my guess is car is not drive-able. key point1 (a dead car)
point 2, engine starts and runs. and races on demand with gas foot.
point 3, im lost. (no trans stated or clear symptoms.)

my jeep has 6speed manual box
and the clutch allows me to start car.
on Automatics trans must be in park or neutral to crank engine.

"it will go till i touch brakes"



I read that 10 times,
my 2nd guess. the engine stalls ?

IS THAT IT, stalls means engine RPM is 0
and right foot actions are dead.
and all dash lamps glow, telling you STALL is now.

what would happen if you put it in first gear,put your foot on the clutch then try to start the car....of course pick a place where safe!!!...if it rolls forward while cranking ,the clutch plate is touching the flywheel (in other words the clutch all the way down while in gear while cranking,should NOT touch the flywheel(transmission part that makes the car move) so if it moves then it shows the transmission reacts to the clutch touching the other jiggamathig. Possibly clutch system needs bleeding (air in the hydraulic system). I'm sure your car has this thing called a "clutch slave cylinder". Now,this is one thing I would check first.

the question is-- was you foot on the brake at home or was just the hand brake applied
when driving , slowing , stopping standing , all have the foot on the brake which is activating a brake booster and if that is faulty , the vacuum leak causes the problem

You vehicle uses a Idle air control motor,(IAC) when you put a load on the vehicle (Drive or reverse) the ECM detects the load and idles up the IAC, even for the A/C (air conditioner) You can try a throttle body cleaning. or a new IAC

pull off the transmission transition switch wire pluged on to tranny
start car drive should be fine never hook op again 0 money
or pay 700 dollars to install a new one
or buy switch pull tranny and install your self

I dont know why, but one time my truck was low on trans fluid and after I topped it off, it didnt stall anymore when put into gear. as fro the odometer i dont know, it may have to go out completely before any diagnosis can be done.

Sounds like your vacuum assist brakes diaghram has sprung a leak. Pull the hose to the assist and plug it with a bolt or something. Then try it.

change the module

You have a bad switch at the brake pedal. Or a loose wire. Try light pulling on the wires on the switch at the brake pedal under the dash. They should be tight and secure. If tight and secure the switch could be bad.
