    Thanks for your quick response. Do you think the fuel pump will be expensive to fix?

    sounds like the fuel pump quit, have the fuel pressure checked.

Around $300 US installed in most cases, the fuel tank must be removed as the pump is in the tank.

humming could be the motor turning round but not engaging with the flywheel. you can check this by hitting the starter with a spanner a few times. if it starts up after you have a sticking solenoid. had to do this a few times my self to get engine started. replace starter as soon as possible if it works. usually happens if you not driven car for awhile.. or you do a lot of starting and small trips.

Hello there, First you need to make sure you have a good battery, todays cars are very picky on having the proper voltage to make the systems work properly. Just a tip for you, You can take your battery out and take it to an Autozone or advanced auto parts store.They will charge your battery as well as test it for you to make sure it is working good for you.

Before you spend a lot of money on parts not needed I would make sure the battery is good and then try and see if you are not getting fuel from the fuel pump, Most cars you will hear a slight humming noise coming from the gas tank when you first turn the key on, this will last about 5 seconds, try and listen for this if you here it then your fuel pump is working.

Good Luck, I hope this helps you some.

Tacoma won't start, or shift out of park.


Try putting foot on brake, or is key in ignition, also over-ride button by shifter. Auto's have safety micro switches in these places so not to have car in drive and start, "extremely dangerous" Try this first easily missed. lol
