Hello, my name is***** have over 13 years experience in the automotive industry. I have worked on numerous vehicles. Ok lets start with some questions.

How much is the psi on each cylinder?

How many miles does the vehicle have?

Did it ever overheat?

Do you have a scan tool? If so, any communication/codes?

Is there any water in the cylinders if you pressure test the coolant system? Is it losing water?

Last oil change?

Any water in the oil?

If you could answer these questions would be great!

Customer: replied 1 month ago.
175 psi on all cylinders ,195,km did not over heat ,no coolant leak ,no coolant in oil or breather
Expert:  Michael Solis replied 1 month ago.

What about codes? Any codes? Any communication to the pcm?

Customer: replied 1 month ago.
no codes , had a scanner pluged in ,map coolant and air temp are good theft system was in run mode ,had crank rpm when cranking
Expert:  Michael Solis replied 1 month ago.

No communication errors on modules other than the PCM?

Expert:  Michael Solis replied 1 month ago.

Crank/cam signal coloration within spec?

Expert:  Michael Solis replied 1 month ago.

No loose grounds?

Expert:  Michael Solis replied 1 month ago.

First remove the cover off the top off the intake and verify the G101 ground and wire harness is good and the bolt tight.

2. Voltage drop the Engine Control Module (ECM) powers and grounds. And check the wire harness and connections between the Throttle Actuator Control Module and the Engine Control Module (ECM).

Expert:  Michael Solis replied 1 month ago.

check engine illuminates key on bulb check?

Expert:  Michael Solis replied 1 month ago.

Obviously no key symbol right?

Expert:  Michael Solis replied 1 month ago.

Just to see if it starts with scanner connected, give it a try if you have not yet.

Customer: replied 1 month ago.

Customer: replied 1 month ago.
were can I access diagnostic information
Expert:  Michael Solis replied 1 month ago.

Have you tried attempting to start while scanner is connected? (on honda's, if a bad ground is present it will start with having a scanner connected)

Expert:  Michael Solis replied 1 month ago.

let me check the diagrams one moment...

Customer: replied 1 month ago.
scanner was connected while cranking ,vehicle was driving fine just quit on the road and now no start
Expert:  Michael Solis replied 1 month ago.

24/23/22 ecm/pcm location

Expert:  Michael Solis replied 1 month ago.

Resistance value? never done a resistance value on cam/crank sensors, always monitored the 5v ref volt drop scope pattern & make sure no glitches were there. You can do it with the volt meter, but would only show you average drop reading, you would have to connect to ground and the cam signal wire, I can give you the pin out of each sensor if you like

Customer: replied 1 month ago.
do you have diagnostic flow chart for crank no start ,pcm terminal id location to do circuit continuity
Expert:  Michael Solis replied 1 month ago.

Yup, one sec

Expert:  Michael Solis replied 1 month ago.
Intermittent crank and no start. No codes set.Average Reported Mileage:171601Tests/Procedures:

1. Verify immobilizer light goes off when no start issue is present.

2. Check fuel pressure and injector pulse. Try to start vehicle on false fuel.

3. Check spark is present, check spark strength during no start issue.

4. Check compression and cylinder leak down

5. Check cam timing and valve adjustment.

6. Make sure it does not have diesel.
