It is probably a bad battery. If the battery is good, check your terminals. Make sure they are clean and the terminals are tight. They may need new ones put on. If all this checks out, it may be your starter solenoid or starter. Check your ignition fuse as well.

you may find that also your tail lights are not working. have you just installed a after market head unit? if so remove the earth wire and just have the antenna for the earth, then replace the blown fuse which will be some where by the foot pedals.

The computer in your truck picked up a problem. Go to Autozone and they will be able to read it for you. It doesn't cost anything. They will let you know what they found and tell you what is needed. If you need anything else, feel free to contact us again. Thanks for using FixYa.

This could be low brake fluid level in the master cylinder or possibly a faulty switch on the emergency brake .

replace the fuel pump or check the relay and power going to the fuel pump first. if its getting voltage it might be bleeding the pressure back to the tank

replace idle air control motor

Haver you had the throttlebody cleaned? very common problem and easy fix.

LINKAGE ADJUSTMENT. PART WORN NOT ALLOWING THE LINKAGE TO RETRACT IF IT WORKS IN THE OTHER GEARS BEFORE DRIVE

recheck radio wiring for loose connections.

Hi and welcome to FixYa!

I strongly suggest that you have the car diagnosed. If the check engine light is on there must be a faulty sensor somewhere and having it scanned will show the fault code. By then we'll know what sensor should be replaced.

Hope this helps and thank you for using FixYa! Have a good one!

Check this site. Full of info and color codes. http://www.etrailer.com/faq-wiring.aspx
Did you use a direct plug that plugs into the harness or just a 4 way plug spliced in?
On this truck you will have to have a wiring converter... it will use turn signals and brake light (3 wires in) and convert them to a 2 wire which is what is required. Hope this helps, Mike

Hi, Look into you MAF sensor...
Mass-Air-Flow sensor... it helps determine the right air/fuel mixture based on the incoming air temp and flow AFTER the air-filter.
So it gives bad readings and it stalls the car, particularly when coming to a stop from higher speeds... it should also be noticeable when bliping the engine.

Sometimes the sensor's get gunked up and you can clean it with brake cleaner... delicately with a pipe-cleaner... or a full on replacement of it.

It should be a simple straight forward job... the sensor is in the air intake tube between the intake manifold and the air filter.

This is baloney. I don't believe the computer is hurting the sensor. You could check that with a voltmeter. Do you have the trouble code? If not, can you go to a local parts chain and get a free scan? Need the actual code to advise you, please. Also, do you have the 4 or 6 cylinder engine?

I had the same problem on a 1996 Tacoma 4x4 and the trouble was the solenoid valves on the inner fender liner drivers side. It is an electrically controlled vacuum switch that controls the switch on the transfer case. Not sure if yours is the same ?

DRAIN WATER FROM RADIATOR, REMOVE WATER PIPES THEN RADIATOR. LOSEN THE ALTERNATOR BELT AND OTHER BELTS AND REMOVE. LOSEN FAN THEN REMOVE AND THEN YOU HAVE ACESS TO THE WATER PUMP.

check the bulbs. do the blinkers work ok?

The headlights are suppose to turn off while the starter is engaged. It gives the starter more amperage. But the problem is more than likely your starter solenoid. It will click when the starter is suppose to engage. But the solenoid is not passing the power through it to the starter. You can take the starter off and have the starter and solenoid tested at about any auto parts store. For sure Autozone or O'riely's.

uhm to my knowledge there is no alternator fuse, but i could be wrong. usually those just go and you get an alert in your cluster that looks like a battery and it stays on that means the alternator is fried and jsut get a new one, the alternator has a wire goin straight from it that goes into the battery to charge it there is no fuse that i now of

Your loacle Autozone or O'relly's should be able to look this info up for you.

I prefer Interstate Batteries. They seem to last longer than the others. Costco brand is about 30% less cost, if that is an issue.
I dislike Sears Die Easy, as I have witnesses sooooo many die much quicker than expected.
