Automotive Board: Car won't accelerate when giving gas
Posted on 10/15/16 at 7:12 pm
Posted on 10/15/16 at 7:12 pm
Trying to help my sister (no pics) out with a car issue. Car is a 2007 Ford Fusion. I'm not savvy at all as it pertains to vehicles.
She drove it this morning to work and back with no issue. Went to leave this evening, and the car was completely dead. Installed new battery for her. Car starts, sounds normal.
Upon shifting the car into drive, and attempting to accelerate, the engine will not rev and the car will not accelerate. It will move forward or backwards (in drive or reverse) slowly as a normal vehicle would if you were giving it no gas.
I'm trying to exhaust all of our options, but it's difficult to do it via trial and error, late on a Saturday night.
Any OT mechanics know what the issue could be off the top of their head?
1) Transmission fluid low
2) Something about programming the battery, since it's new
3) Transmission completely shot
Those three are the only things I could come up with in about 20 mins of google research.
For your troubles:

Probably transmission issue not the battery. Happened to me a while back. Pain in the arse. Appreciate the solution to my troubles. Good luck with the car

Sounds like the thing connecting the pedal to whatever is broken. Can't remember what the name of the part is.
I suck at cars too

Well there isn't "programming a battery" I can tell you that much. Battery exists to start the car.
Ecu fuel map might be jacked up. Leave it in park and rev it a few times.
What type of car is it?

Needs a new Johnson rod.

Seems logical, but also like a huge coincidence that it happens the first start after a new batter is installed.

Hmmmm, never heard of that, but I'll look into it as an option.

I read something about the fuse box next to the battery?

Car won't rev at all, unless you mean just pushing the pedal regardless, in which case we did and we got nothing.

2007 Ford Fusion

If the car is new, might not have a throttle cable. Most new cars are fly by wire. Meaning, there is no linkage. The ECU reads the throttle position and controls fuel delivery

Upon further research, I stumbled upon some people online with the exact same issue. Apparently lots of people have the same issue when changing the battery on their Fusion.
We were supposed to do something with the fuse box next to the battery housing before we changed it.
There are also some who had success, simply letting their car run so the transmission can "re-learn". See below
I appreciate all of the responses thus far. Here's more Emily Ratajkowski for everyone

quote:
When the battery is disconnected or a new battery installed, the transmission must relearn its adaptive strategy. As a result of this, the transmission may shift firmly. This operation is considered normal and will not affect function or durability of the transmission. Over time the adaptive learning process will fully update transmission operation to its optimum shift feel.

Sounds like TPS. Are there any codes showing up?

That's actually the page I was on

My wife has a 2010 Fusion. Same issue as yours and has happened twice since we got it. Its the throttle body. Known issue. Ford has done an extended warranty on this issue. Not sure if 2007 is included but call a dealership and they will verify it.

Where is her brain again?

Possibly fuel pump or catalytic converter.
Would need to plug diagnostic into engine computer for failure code though.

Start the engine first

If the engine won't rev, it's the throttle cable or bad sensor if it's drive by wire. It is not the transmission.

Exactly, start with the damn obvious problem. Once it's clear that the accelerator works then go try out some wild theory about the transmission. It's dumb to jump to conclusions, unless you work for the dealer and just want to charge a bunch of stuff to warranty or the customer

Its the throttle body I guarantee. Has happened twice to us. Its a known issue with the Fusions. Ford has extended the warranty for certain model year Fusions but Im not sure the 07 is included.

You would be correct. This car has no throttle cable. It's drive by wire design. Engine will not accelerate unless the throttle body is working. Can't believe some of you thinking this is a transmission issue.

More info required.
In the op you stated the engine will not rev up?
Does it try to increase rpm but spudders and misfires? Or does it never even attempt to increase rpms like it would had you not even touched the gas peddle?
