Driving down the highway, had to hit the brakes fairly hard to slow down, then when I went to accelerate it shut off, has gas in it, no prior warning or dummy light's went off, car ran absolutely fine prior to this and now it won't even crank as if the battery is dead but has 12 volts and as off a few days ago was charging at 14 volts. I hear the fuel pump turn on when the key is turned to the on position. At a total loss, need help, please!

Hi,

That is an odd one. In most cases, a crank with no start is the result of either loss of fuel or ignition spark. I'm not sure why hitting the brakes would affect either, but anything is possible.

I guess we can't check for either until we get it to crank again. I realize the battery shows 12v. Do me a favor. Connect your voltmeter to the battery so that you see 12v. Have a helper try to engage the starter. Does the voltage change?

Let me know what you find. Also, do me a favor and check the 7.5 amp, start 1 fuse in the interior fuse box. In addition to checking the fuse, confirm there is power to it. See pic below.

Let me know what you find.

Take care,

Joe
