Hi,

It doesn't sound like you did anything wrong. I suspect the wire at the PCM is shorted at some point. Which fuse was it that had such low voltage? Let me know so I can trace it back to its source.

As far as the PCM is concerned, we need to disconnect the battery and PCM. Then, check if there is continuity to ground. If there is, there is a short at some point.

Let me know.

Good morning, sir, it is fuse 40 that has the low reading. I checked the others and fuse 51 has 0.05. The rest didn't give any reading.

Hi,

If fuse 40 is in the CJB, that is for the backup lamps. It will only have power if the transmission is in reverse. Is that how it was checked?

Do me a favor. Make a list of fuses without power and place them in either the central junction box (inside of the vehicle) or under the hood. I'm getting confused.

Let me know.

Good morning boss, I wasn't using the appropriate ground that is why I was getting those low values in those fuses. So far with the aid of the technician, we are getting the 5 volts at the TPS and injectors. DLC and PCM is communicating. When you turned the ignition on, the hazard light stay on and goes off. It shows that the new PCM is programmed. He is saying he is suspicious of the power holding relay as its ground is low and the fuse 9 is not getting voltage. He doesn't know why the switching ground in pin 26, 27 of the PCM is not supplying to starter. That is what is required to crank the engine. How do we do? How do we resolve this? I really appreciate you for being there and almighty God bless you real good.

The technician has been able to do of the job. He said the transmission sensor is bad. Rodents has cut off the wire to the fuel pump socket (connector). Can I get the part number for these? Going by him, the car will start now. You have been of immense help and support. God bless you for showing so much concern.

Hi,

As far as a part number, I did find one for the transmission range sensor. See pic below. That is the OEM part number. As far as a part number for the fuel pump wiring harness, that isn't something that is provided in any of my manuals.

Let me know if this helps.

Joe

Greetings boss, the technician has made significant progress. The car starts from the key. However, there are still some shortfalls. The number one is that repeated switch on and off, the well charged battery ran down. The number two is that when the headlamps are connected to a direct power, it turned on, but it cannot turn on from circuit. The number three is that when the car was scanned, it reads circuit fuel A, but he said that the fuel circuit has been repaired as the fuel pump was changed. Fourthly, the sound is not very comfortable. Lastly, when he turns on the ignition, the battery charging, airbag and low oil pressure stay lit before going off. I can't remember that is how it used to be. From the headlamps that has not come up and poor charge storing, there is still a faulty circuit which is the original problem. All advice and suggestions are welcome. Thanks very much and God bless you sir.

Hi,

Wow, I'm not sure where to start. LOL When you try starting it, if I understand correctly, it takes a few tries. That sounds like fuel pressure drop-off. Try something for me. Do this and let me know what happens:

1) Turn the key from off to the run position (engine off) and count to 5.

2) Turn the key off and repeat step 1 a total of four times.

3) On the 5th time, see if it starts normally.

Let me know.

Good day sir, I felt exhausted from the three days working on the car. I tried the key in the engine run not start, in a number of 5 times. Different illumination light turned on and off on the cluster illumination but the car couldn't start with 12.39 volts. I am now looking for a higher voltage battery to start it. I was expecting 12.39 should start it. I don't really know if the problem has been resolved. He said the engine is misfiring, I should service the injectors. From my Haynes manual, the only possible cause of misfire here is the crankshaft position sensor. Thanks very much for encouragement and God bless you bountifully.

Hi,

If you have 12.39v, that isn't the problem. If I recall correctly, 9.6v is the minimum needed for the ignition system to properly function (that is while the starter is engaged).

After it runs and then stalls, does it restart again, or do you have to wait?

Let me know.

Greetings, boss. I just want to thank you for your immense contributions. My observation is that the ignition always responds when the key is turned to the on position, but the car can't start. All the cluster instrument lights will come up. Then, I just noticed that the moonlight is not working yet, along with the trunk interior light. I can see they are controlled by the battery saver. Unfortunately, from my last discussion with the technician, he hasn't grasped the concept of the battery saver. Do you think the battery saver relay or circuit is an issue here? Can a parasitic draw test resolve it? The engine is making an attempt to crank whenever it is turned on, which shows that the starter motor is engaged, but the car won't start. Thank you very much for your contributions and efforts. May almighty God enrich you with knowledge and wisdom.

Hi,

If I understand correctly, he got it to start but when it shuts off, it doesn't want to restart. Is that correct?

If that is the case, then either we are losing the ignition spark or fuel to the engine. When it cranks and doesn't start, see if it will start if you use starting fluid. If it does, then we have a fuel related issue.

As far as a parasitic draw, if your battery maintains 12.39v, that isn't the issue. If there was a draw, the battery voltage would drop off.

Let me know.

Good morning, sir. I left the battery insitu in the car overnight. I checked it at the night, it was 12.32. And this morning I went to check it again. It is 12.25. I am still leaving it in the car till in the evening to see the reading. He carried out the procedure you mentioned in the course of his work. One of programmed key was cut manually, so it doesn't fit well. Trying to get the other one cut. As far as fuel system, he suggested I change the fuel filter and I am trying to get that. I still see the car starting with so much resistance which it was supposed not to be. Thank you very much for coming through.

Could there be correlation with the images and what I am insinuating, and the seatbelt illumination could an indication of something?

Hi,

I don't feel what is identified in the schematic is the issue. Also, the battery drop isn't too bad. Remember, there is a constant draw on the battery at all times regardless of if the key is in the ignition or not.

Let me know.

Good day boss, a wrap up of the components that need to be fixed before the car can be on the road. I just discovered to my greatest dismay that I couldn't find the power steering switch connector. I saw it on rockauto. Com but don't know the perfect match. I also need to replace the upper coolant reservoir hose, ignition capacitor, the exhaust nut, the throttle body bolt you identified earlier, the injectors, the horn, fuel filter. I might not have OEM of some of these parts again. Kindly help me with the part numbers or a direct link to source for them online. It could be their aftermarket or rebuild. The one you feel could be affordable and reliable quality. I want to avoid error because of the time and distance for me to order and receive them. Thank you very much and God bless you real good. We have made so much progress. Thanks to your support, patience and time.

In addition, please where does the hose I identified with blue go into and the one with yellow coming from the exhaust seems to be broken off at the opposite end. Where is it supposed to continue to or join to? Thanks once again.
