Does not start, fuel injection problem?

This can be because you are out of gas, the primary fuel pump stopped working (common) or the fuel pump relay stopped working, here is the location of the fuel pump relay so you can swap it out, then while cranking the engine over test the grey wire for power and if so the fuel pump needs to be replaced.

Here is how to test the for power and I have left the instructions on how to replace the pump which the tank needs to be removed for.

Here is how to drain the fuel from the tank:

Can I ask if the security light is flashing when cranking the engine over? Check out the images (below). Please upload pictures or videos in your response to the problem so we can see what's going on.

After i had rebuilt my engine, I couldn't start it. All is right, there's any dtc shown on the scanner.
The pressure in the rail is 65000 kps.
Please help me.

Hi,

In most cases a crank no start condition is caused either by a fuel related issue or an ignition problem.

See if it will start if you use starting fluid. If it does and then stalls, it's fuel related. If there is no change, then I need you to check for ignition spark at the plugs.

Here is a link that explains how that is done:

Additionally, if you can record it cranking and upload it for me to hear, I should be able to tell if there is a timing or compression issue.

Let me know.

Hi Joe, In this engine there's no spark. Sorry, I forgot to mention that the engine Z20S is a diesel one.

Thank you very much.

I would try a little starting fluid to see if it will run that way you can see if it is a fuel problem or not.

Thank you sir,
Yes it runs and stall.
By the other hand, I hear the fuel pump working,but the fuel return to the tank.

It sounds like you need a new fuel injection pump, do you have fuel in the tank? Also lets run the codes to see if any are present.

Please go over this guide and get back to us.

Thank you, sir,
There is non mil on the dashboard.

Does the engine run on starting fluid? They make starting fluid for diesel engines, and if it does run the high-pressure fuel pump is probably bad. I would run the codes anyway even though you don't have a check engine light.

Hi,
Yes, the engine runs on starting fluid and stop. Besides this, there is an incomprehensible DTC code p0335, because the sensor is new, the wires and connector are good. The reluctor wheel is also okay. Please help.

If the wiring is good then the PCM might be bad.

The code P0335 typically refers to a "Crankshaft Position Sensor A Circuit Malfunction"

I would confirm the wiring is okay then replace the PCM with a preprogrammed unit you can get by searching google or ebay.

anything?

Thank you sir.
But the scanner shows the number of turns of the crankshaft when I try to start up the engine. Is this mean that the sensor is okay?

Yes, if it shows RPM it is working, we should have done this early, can you please turn the system on and check all fuses please?

Be sure to check the BCM fuses. Check out the images (below). Let us know how it goes.

Thank you, sir.

Thak you very much, sir.
All fuses are okay.
However, during the rebuild of the engine, I have changed the injectors without their calibration.
Does this interfere in the engine start?
Please send me the procedure to calibrate them.

Sorry, I mean programming.

I have not heard of calibrating the fuel injectors, is there a code for it?

Hi sir,
Sorry, I mean programming the injectors in the ECM

Nope, you do not have to code the fuel injectors to the ECM.

Thank you sir,
But the ecm throw the dtc P268A. Is this have a relation with injectors programming?

p268a “fuel injection calibration not learned/programmed”

The ECM might need to go through a relearn procedure to properly calibrate the fuel injectors. This can often be done with a professional scan tool. Here’s a general outline:
Step 1: Turn the ignition to the "ON" position (engine off) for about 10 seconds.
Step 2: Turn the ignition to the "OFF" position for about 10 seconds.
Step 3: Repeat steps 1 and 2 a couple of times.
Step 4: Start the engine and let it idle for a few minutes.
Step 5: Perform a test drive to see if the code returns.

Please let me know.

I applied the procedure you indicated, but the engine did not start. Maybe I have to use the scanner to reprogram injectors. Thank you very much. Thank you sir,
I'll try this tomorrow.
