Check engine light sometimes does not come on when ignition key turned. As a result the engine turns but does not start. After a few false starts, engine check light comes on then car starts. Also sometimes when car is running, the engine cuts out, then I have to wait til the engine check light comes back on before car can restart. What relay do I need to change and where is located? Cheers. Sifa

If I rev the engine it will hesitate and sputter it will do it no matter what gear I'm in and happens everyday

where is the overdrive solenoide switch located on my suv toyota sr5 4runner.

Is it most likely a bad relay fuse, or solanoid switch.
Which holes in diagnosis
block by fuse box do i put wire ends into to check for code number. I have a 3.0
liter v6 3vze engine.

Wondering if that's true and would that then tell you it's a bad starter if it doesn't start the truck? Thank You

It started off as a light vibration when accelerating from stop position. Now its a heavy vibration on flat roads. When on a small hill it is terrible and almost doesn't move. Whatever it is needs to be fixed asap. Thanks in advance for your help

After doing head gaskets on 3vze, it rattles like a diesel in the timing costs .

Purchased car 2 months ago. Window moved slowly then and just stopped moving a couple weeks ago. Need to repair. Always used the key to open window. Have not tried using the switch in the vehicle.

My truck seems to run hot but the temperature gauge works because you can hear it open once the truck warms up. But I'm not sure if it's accurate and recently the engine runs at 150-173°F and the radiator at a constant 174-176°F. So I want to know if that's normal for my truck because I know during its time the engines ran hot to burn emissions.

Manually shifting doesn't help. Was intermittent, but now has become permanent...

vehicle stopped running after I turned the corner.
have replaced the radiator, knock sensor, starter, hoses
could it be fuel injectors

Help please
