My car won't start, I drove it the day before yesterday and today it wouldn't start. It dosen't make any sound at all. All the lights are coming on but it will not start. It is a 2002 Ford Taurus and has double overhead cam.

flassed less engine power wth????????? Flashed reduced engine power ! Electronic throttle control problem ! Your best bet ,take it to a GM dealer , buick , cadillac , GMC . You do not have diagnostic test equipment or knowledge to even diagnose this.

Sounds like the shift cable has broken

sound you have a blown clutch slave cylinder

Something must of hit the starter wiring when you drove on your flat tire.

Sounds like your alternater, get a multimeter set it to volts start the car then check the battery is getting 14 or over volts from the alternater to the battery , if your getting less than that it's not putting enough volts back to the battery to run the car with good luck colin

Definately sounds like the fuel pump

Check the anti-theft module and relay

That would make sense, because when he jumped your car if he left it hooked up for awhile. Then he charged your battery up, so it started the next day. Then you drove to his shop and back it ran the battery down. It's easy enough to test and change alternators you could take it to autozone or O'Reillys if there is one close they can test your alternator. If you have more questions about this or if you would like to try and change it yourself just reply to this post and I will walk you through it.

check the fluid again,, if the brake pedal feels spongy at all,, you have air in the lines still, if so , bleed the brakes,, unhook the battery to clear the light, and try again

Sounds like the fuel pump has an issue with a safety on the pump itself.
