aaargh. i was installing some stereo stuff in my car. when i finished my car wouldnt start! i tried to jump start the battery but that doesnt seem to be the problem since all the lights and electronics turn on. could i have fried something while installing my stereo stuff? what else is weird is that the brake pedal will not go down. it feels like its locked in place.

i did do a search on the forum and you guys seemed to already have pointed out some possibilities..i.e. starter, fuel pump etc. i'm really not good under the hood so i was wondering if anyone could pinpoint my problem so i don't mess up my car more trying to figure out whats wrong!

again, i just installed some audio equipment and the brake pedal doesnt go down. thanks!

btw my brother is a med school student and needs the car to work all day at his hospital in jersey! so this is kinda important! my prayers to everyone and their families that were affected.

 

Possibly.

Raise the hood. Use a flat blade screwdriver to remove the cover from the long link and fuse box adjacent to the battery. Check all the links and fuses you find there.

 

You are reporting a no-crank problem.

Always do the easy check first. If your vehicle is a 5-speed, make sure the clutch pedal is all the way down when you twist the key to START. If automatic, jiggle the shifter while attempting to crank. Try cranking in both Park and Neutral. If those steps are unsuccessful, consider ...

- discharged battery (dim headlights with engine off)
- weak battery (check voltage at terminals while cranking)
- loose or dirty battery terminal connections at the battery
- loose or dirty battery-to-body ground connection
- loose or dirty battery-to-engine block connection
- bad ignition switch
- bad clutch safety switch (5-speed)
- bad neutral safety switch (automatic)
- bad inhibitor relay
- bad solenoid
- bad starter

The starter is an expensive item so you should check the other items before spending the money on a replacement.
