Engine cranks but does not start?

Hi,

I need a little more info. What pins were checked? Also, have you determined if there is spark and fuel to the engine? One is likely missing causing the no start.

If you use starting fluid, will it start for a second or two? Also, what model is the truck, and what size is the engine?

Let me know.

Joe

Please if I could have diagram of power and ground for kick starter. I have been getting a short circuit, 9 volts going to the kick starter instead of battery current.

Hi,

I would be happy to help, but I need the model and engine size. Let me know if it is a Tacoma, a Tundra, or a Hilux. Also, which engine is in the truck?

I need that to get you the correct wiring schematic.

Let me know.

Joe

It's a Hilux 2018 model.

Hi,

I attached the wiring schematics for the starter circuit. Note that these are for a vehicle made without a smart key. If that is incorrect, let me know.

Take care,

Joe

See pics below.

Perfect. Its correct. May I also get the pin out Diagram for the rail preasure sensor, also the resistance if testing with a multimeter. I notice I get 2.5 volts coming into the rail preasure sensor, I thought I was suppose see volts.

The rail pressure sensor is a two-wire cable. I need the input volt to the sensor and a resistance if using a multimeter to check if the part is good. Using my diagnostic tool, I notice the value remains at 0 when cranking the car on live data, but the pump works well because you can see fuel coming out from the injectors.

Hi,

I'm looking through the wiring schematics and component identifications for the fuel system and I see no fuel rail pressure sensor. Could you be referring to something different?

Take a look below at the pics I attached. Do you see what you are checking?

Let me know.

Joe

See pics below.

This Hilux is a Diesel engine not a gasoline. It has the rail and an Injector pump. What I need is the input voltage signals to the common rail pressure sensor. It's a 2-wire pin. What voltage I am expected to see. 5volts from the ECM or 5volts. How can I also test the fuel rail pressure sensor using a multimeter to check the resistance?

Thank you Joe.

Sorry Joe, I made an error, it is a 6-pin wire sensor for the rail fuel pressure sensor, and the limiter sensor is a 2 pin.
VIN: MR0kB8CD6J1203309.

Hi,

This is making sense to me now. I am struggling to find the info you are looking for and I know why. The only info I have is for a L4-2.7L (2TR-FE) gas engine. I show nothing for a diesel.

So, I went further into the manual and found a 2.8L turbo diesel available on a 4wd model. Is that what you have? You didn't indicate which you had above and when there isn't anything listed, I assume it's 2wd. LOL

As far as voltage input, it should be 5v. To test it with a multi-meter, you will be checking for Ohms of resistance. I attached the directions below.

Let me know if that helps or if you have other questions.

Take care,

Joe

See pics below.

Perfect Joe, thanks for the resistance values.

If I could get the input volts to the 6-wire sensor it would be enough for now. If I need further help, i will contact you.
Thanks very much.

From what I am finding, 5v is correct. Voltage from the ECM should be between 4.5v and 5.5v. See attached.

Joe

You are the best. A million thanks. God bless you. Anything more I let you know.

Hi,

You are very welcome. I'm just glad to know it helped.

Take care of yourself and please feel free to come back anytime in the future. You are always welcome here.

Joe

Thank you.

I come back to you Joe. Please may I know the voltage which has to be on the I injectors connector. I have a tester using a multi meter, I read 2.5 volts on both cables that goes into the injectors.

Also, if I may have the resistance test on injectors and crankshaft position sensor.

Thank you, looking forward to your reply.

I tested the input voltage of the crankshaft position sensor, input reading, red, yellow and white cable. Red ground, white 5-volts and yellow 4 - 5 volts. When cranking reading with multimeter, on the signal which returns to the ECM, I get a reading of 2.5 volts to 2.7 volts.
I would like to know if that ready is okay.

Thank you.

Hi,

From what I am reading, the signal voltage should be around 2.5v. As far as injector voltage is concerned, my manual doesn't have that information. However, in most cases, it is battery voltage and a ground patch to complete the circuit is provided by the ECM.

Joe

Okay, thank you. Do you have any data information for crankshaft position sensor? For testing using multimeter?

This is the test I have carried out using a multimeter, I connected all 3 wires to see what is happening when I crank the toyota pickup.

The signal wire which is yellow in color, has a standby current of 5 volts, the white power cable has 5 volts static, while the red wire cable is ground. When I crank, the reading I get from the signal wire which is yellow in color, drops to 2.5 and plays within 2 8 or 2 9 volts.
My question is simple, normal as the crankshaft rotates, the faster it rotates the higher is suppose to read on the signal, and when vehicle is idling, it should play within 5 volts. Please let me know if I am correct, if so, this means the crankshaft sensor in my pickup is bad, because, instead of the volts increasing or atleast maintains 5 volts to start the car, it rather drops all the way to 2.5 while cranking.

Hi,

You are correct. It does sound like a faulty sensor. Let me know if that takes care of the issue.

Joe

Please can you help me out with the Injector voltage and signal for the diesel Injector? I am getting on both wires going to the injector about 2.5 volts on either side. Also, when I did the resistance test on my injectors I got 0.1 oms of resistance. I need to very if this is correct before going to replace my crankshaft sensor.

All I need right now to round up my test on this 2018 Tokyo Hilux diesel 4wd, is the voltage that needs to be on both injectors wire connectors, it's a two wire cables. I would also like to know the resistance test for the Injectors.

I would really appreciate it if you have this information in your system.

I ran into a wall when checking info. I need the production date of the vehicle. It appears there are two variations of the powertrain management circuits based on date. See pic below.

Let me know.

Joe

See pic below.

Hi,

I was able to find the testing for resistance, but there is nothing I am able to find specific to voltage. I would think it would be B+ voltage but I can't confirm it. Any injector that I can think of works off 12v. They have power all the time and the ECM provides a ground path for the injector.

Take a look below and let me know if that helps.

Take care,

Joe

See pic below.

Thank you. I was rather getting 0.1 ohms of resistance. Probably the value is not as specified in the table below.

I had these two codes fault stability and turbine transmission speed sensor.
I hope the turbine speed sensor one of them is responsible for why I am not getting the 12 volts on my I injectors. Those are the only two codes I keep getting now.

P1604 and 0715. The input turbine speed sensor and faulty stability which has to do with starting system. Maybe you can share your expertise.

Thank you Joe.

Hi,

The 715 is related to the trans and I wouldn't think it's related. 1604 does seem related. I attached the diagnostics for 1604. Take a look through them and let me know if you are comfortable performing them.

Take care,

Joe

See pics below.

Thank you very much.

Hi,

You are very welcome. If you have a chance, let me know how things turn out for you. Also, let me know if I can help in any way.

Take care,

Joe

Thanks again. However following the values of the injectors, all 4 injectors read 0.0 ohms. I am sure those injectors are not good.

Hi,

If you have 0 resistance, the injector is bad. It should be between 11 and 14 Ohms. Some can reach up to 24 Ohms.

Take a look through this link:

Let me know.

Joe

Mine is a diesel nuzzle with no fuel pump in the tank, does the resistance remain same?

Hi,

I can't be sure if they are the same, but I don't see how they would be 0. I would think they would still fall into the same resistance range. Did you get a different reading?

Joe

Yes, I took another reading from a Mercedes sprinter diesel injectors, readings were withing specification. I concluded injectors with o.oo ohms resistance are bad.
