TACOMA CANNOT START THE ENGINE

1. If the timing belt breaks the engine would still turn with a socket. It's non interference so nothing is in the way of the pistons when you move them via turning the crank manually.

2. Yes. The ECU does control spark and fuel even on startup. While there is some automation via valves built in without the ECU the truck won't fire.

3. Passenger side kick panel on 1st gens IIRC.

 

All of the pulleys controlled by the fan belt would still move. However if the timing belt is snapped the cam shafts will stop turning and the valves will stop functioning.

The fan/alternator belt and timing belt are different things. I think your mechanic confused you about that.

 

have you physically turned the engine? You say theres a click sound or does it actually turn over? It could be the engine is seized. It could be a bunch of other things..

 

According to what you told me above, should I focus on the T-Belt first? Again, every time I tried to turn on the engine, I saw all of the lights in the odometer lighting as normal and heard a sound click, but nothing else after that.

 

No. Forget the timing belt at this point. Check the ground to the starter and the wiring you saw amiss. Stop focusing on the T-belt. At this time it's important to figure out why the starter is not getting power and that has nothing to do with the timing belt.

 

I did not turn the engine myself but I looked at and saw the previous owner did couple times before I bought the truck. The engine turned fine. Again, every time we, the previous owner and me, turned the engine on with the key, all of the lights in the odometer was lighting and we heard a sound click, then nothing else after that.

 

Ok, I'll do that. According to all of your subjections and advises, I plan to check the ground cables on the battery, starter, the wires on the driver side under the steering wheel, and the ECU. After that, if it's still not working, then I have no choice and have to pay for a towing to tow it to the shop. If any of you have any more idea, please share and subject it to me because I have no other way now.

Answer your previous comment or question above:*** I did not turn the engine myself but I looked at and saw the previous owner did couple times before I bought the truck. The engine turned fine.

Usually, how much do shops charge, all I need is just to make sure that the truck can turn on the engine and run only.

 

It depends on the shop and how familiar they are with your problem.

If the ECU is fried or you have wiring issues I'm not going to lie to you, it will get expensive fast. That's why it's best to check the cheap things to fix before anything else.

 

Thank you for your subjection. I'm busy now and I plan to check them on the July 4th weekend. Here is my plan to check:
1. The Throttle Position Sensor which is the code 'P0120'
2. The Ground cables on the Battery
3. The Ground cable on the Starter
4. The Fuse Box Cables connection
5. All of the Relays and Fuses
6. All of the wires on the Driver side under the Steering Wheel
7. The ECU

As soon as I finish checking, I'll report and post pictures back here to all of you. So if any of you have anymore idea, please share or subject them to me.

 

No ones said it ....but check the fuses...

 

Ok, it's in my list above too, so I'll check it.

 

I had a issue with my truck not starting and it was one of the square fuses under the hood.

 

You said square fuse, are you talking about the relay? Which one? What color is it?

 

If it's square it's a relay. They do fail sometimes. One of mine failed on a fairly new Tacoma.

 

There are many relays, so do you remember which one or what color was it?

 

I have a 2nd gen. I'm no help to you on which relay is which. Check your owners manual. There might also be a layout on the fuse panel cover that would help.

 

Ok, thanks.

 

It was pink. And no, it's not a relay. It's a fuse.
Like The bottom. Check carefully, it's hard to tell.

 

My bad. I thought square=cubed like a relay. I own a couple of Fords. Those box fuses are extremely common on their trucks.

 

Thanks for posting a pix. I'll check mine. I know mine are completely difference from yours but at least I have the idea which one.
