#9 of 17 2007 4 runner ignition problem by drcarla Feb 05, 2009 (12:55 pm)
I have a 2007 4 runner. After shutting the vehicle off and letting it sit for a few minutes, when I try and start it, it cranks over and over without starting. When I turn it off and start again, it works. I only have 11,000 miles on it and it is still under warantee.   Any ideas?
#10 of 17 PLEASE HELP 1994 Toyota 4runner Electrical Problem. I need expertise pleas by gschaut Mar 07, 2009 (4:27 pm)
1994 Toyota 4runner. I connected a jumper battery in reverse polarity. Blew the 80 amp breaker and the fuel injection fuse. I replaced both and started the car, drove two blocks. Truck ran fine for first block as if there was no problems. Then it seemed to have a heavy electrical power shortage, dashboard indicators lit up and truck began to bog down towards a stall. I shut it down and parked it. I checked fuses under the dash and all seemed to be intact. To replace the fuel inj. 15 amp fuse, I pulled the hazard light fuse and used it. I was just going to drive to the parts store and buy the replacement fuse, but now the car sits and I don't want to try to run it until I know what else is wrong. CAN ANYONE HELP PLEASE. THOUGHTS, IDEAS, POSSIBILITIES.   THANK YOU. gary.schautgmail.com Replies to this message: tidester (Mar 07, 2009 9:45 pm)

Replying to: gschaut (Mar 07, 2009 4:27 pm) You may have damaged your alternator and/or fried some electronics (e.g., ECU).   And, by the way, we advise against posting your email address in public postings.   tidester, host SUVs and Smart Shopper
#12 of 17 Could This Be Electrical? by bassnvox Mar 08, 2009 (5:23 pm)
I have a 1990 4Runner 3.0 V6 4WD. The car bogs out, makes a metal grinding sound, and loses power at 2000 rpm, it has minimal power until about 2600 rpm, once I pass that it is fine. Also in 4th and 5th gear, the pedal will be floored and I will have no power and be unable to pass 2000 rpm, the only way around this is too down shift and tach up the engine so that I will go into gear higher than 2600 rpm. I have recently replaced the max sensor, fuel filter/pump, all gaskets inside the block, and cat converter. I also have a clean K&N intake system, and I run high mileage synthetic blend valvoline oil. I don't know what else I can repair or replace to fix this and it's becoming very expensive. What can be causing this?   Thanks, -Josh
#13 of 17 Power front seat by 4runnernj Apr 10, 2009 (12:21 pm)
I have a '98 4runner with about 137,000 miles. Just recently the front passenger side power seat stopped working correctly. when you try to move the seat up or back only the right side of the seat moves. The left side remains still. I looked under the chair and found a single wire loose and reinserted the line. When I tried it after that the chair wouldn't move at. I pulled the line again and the right side would again move but the left remained in the same place. Any suggestions?
#14 of 17 truck died at highway cruise speed by vetteman_42 Jul 20, 2009 (9:54 am)
1988 4-runner w/400k miles, was running great until it died suddenly on highway 2 days ago. A highway guy tested & said no spark. I've replaced both the Coil & the Ignition Module on advice from various people - it still cranks fine but no spark. I'd already checked fuses under hood, but have no diagram for under-dash breakers & relays. Can someone tell me what, if any, other fuses or electrical/electronic components are involved & likely to have failed suddenly, & where are they?
#15 of 17 Alternator up-grade QUESTION PLEASE READ AND HELP? by slashman Jul 24, 2009 (11:56 am)
Hello!    I'd like to thank you for taking the time read this email! I have a 1990 4-Runner V-6 4wheel drive 3.0 Liter engine. The stock 60 AMP alternator just went out and I had heard that you could upgrade to a higher alternator with an out put of 130 AMP. The 3.4 liter Toyota years 95 1/2 to 2004 but, that it must be the alternator that supports the tow-package? I had also heard that you may have to shim it to make it fit ? I have offroad lights that I plan on installing onto the 4-runner. Do you think that the switch from 60 AMP to 130 AMP will damage the electrical system in the 4-Runner?I can't find anyone that will give me any real information on the subject and I hope that you might have some answers to my questions? I really look forward to your reply and hope that life is treating you and your family GOOD Replies to this message: vetteman_42 (Jul 26, 2009 12:22 pm)

Replying to: slashman (Jul 24, 2009 11:56 am) I appreciate the kind thought. If you live in the Tidewater area in VA, contact Browning's Alternator in Va.Beach. They know their stuff & are honest people, and should be able to help you. I had them rebuild the alternator in my '88 4Runner recently; it works great! I've also had them rebuild my 4Runner's heater-blower-motor, & previously they helped me with a problem on an '85 Vette. They can fix anything that's electric & spins in anything that moves on land or water.
#17 of 17 Re: stereo wont work [tripp2ga] by armadill0 Sep 02, 2009 (5:34 am)
Replying to: tripp2ga (Aug 03, 2007 2:29 pm) I have a similar problem but in a gigantic proportion! 2000 4runner 6 cyl. My son installed a new stereo and it worked fine. Then we decided to pull the unit and install another and the next unit did not work at all. I checked all connections and everything was fine, but the 12v. constant line to the radio only was 8v. When I ran a new 12v the radio will work fine. In addition the car has the following: The clock is very dim and inside cabin light don't work. The parking lights on the front don't work. The bright lights don't work, but the brights light in flash mode. When you turn off the ignition then turn on the lights all the relays click,click,click but lights won't come on. blue Brights indicator light on instrument panel won't light.   I have spent two days following circuits on the thing and have the following: Constant voltage line to the radio tests at 8v. and drops to 2v. when any cabin lights or door switch goes on(lights don't come on) I have checked all light switches and circuits for shorts. Relays for running lights and brights ok. Light control switch (low,flash,brights) ok.
