I was hoping I could get the brains trust together to give a bit of help here.

I am working on a mates new ute running a G16B out of a Baleno with the sump mod for Crank Angle Sensor and a manual gearbox.

The issue is after starting and idling, after about 7 minutes or so, it will just turn off. When you try and start it again, it doesn't start easily and usually requires some form of start-ya-bastard or similar to assist it. It also pops and farts and carries on if you sit there cranking it.

The fuel pressure has been checked and sits at about 40 psi. I have done a compression test which are all within 175 - 155psi. The car sat for about 2 years, so when we first got it, the plugs were changed and the fuel tank drained and knew fuel added along with a new inline EFI filter (Z200 Ryco).

I am in the process of wiring in a CEL as it wasn't completed at the time of conversion. It is running the G16B Baleno computer. It is also running a Jackaroo 85L fuel tank with in tank pump. We have tried running the car with the fuel cap off and on in case it was a fuel lock issue.

I have sprayed cold water onto the Crank Angle Sensor in case that was getting hot and shutting down intermittently.

Does anyone have any other ideas on what might be causing the issue, it seems pretty consistent after idling once started from cold.

This is the ute in question.

What ignition system does it have? Distributor or coil pack, if coil pack where are the coils?

Although I suspect ignition (because of the time/temperature), the fact that the use of starting fluid makes it easier suggests it may be fuel related - have you checked the fuel pressure at that point in time?

Which sensor are you cooling cam position or crank position?

[Brenno]

Hey Fordem,

Its a Baleno motor, so coil packs on the cam cover.

The crank sensor is in the sump, it doesn't have a cam sensor.

I don't believe fuel pressure fluctuates at time of stall.

As far as I know the SY416 Baleno was built with THREE different ignition systems - the first having a distributor on the end of the camshaft, the second having two ignition coils mounted on the end of the cylinder head, and the third having two ignition coils that sat over, I think the #2 & #4 spark plugs.

All three types have a crank position sensor at the front of the oil pan, directly behind the crank pulley; the last two have a cam position sensor at the back of the head where the distributor is on the first type.

I suggest you try cooling the cam position sensor.

[Brenno]

Yup, this one is two ignition coils over plugs 2 and 4 and crank sensor welded into the Sierra sump.

I have tried the cooling method, nil change.

I did some more testing today, managed to rig up the CEL and got code 12 - nil errors.

I started it and was able to idle the engine for over 25 mins without it cutting out. The thermostat opened up and cycled as well. Thought all was going well until I decided to turn it off, and then it was a prick to start again.

I checked TDC on cyl 1 which confirmed that the timing mark on the crank pulley was correct at 0 TDC on the marks.

I bridged the test port and neg port on the diagnostic plug and tested the timing. (hopefully that's what you need to do to check base timing)

And....I couldn't see the timing mark flash anywhere between 20 - 0 degrees.

It looks like maybe its out to like 30+ degrees.....

I am thinking that maybe when the crank sensor mounting location was welded into the Sierra sump, it may be on an angle or not in the right position, which then threw out the signal/timing.

When I am cranking it and use the accelerator, it sometimes fires back out the intake occasionally.

Would appreciate anyone's thoughts on this!

Have you found the cam sensor yet?

[Brenno]

There is no cam sensor on Baleno G16B, only crank

I've edited them to include an arrow showing where you should find the cam position sensor.

My bad, I'm an idiot!

[Brenno]

Update

Pulled the front cover off and checked the cam/crank timing, all lined up.

Pulled the crank sprocket off and checked keyway, all good.

Will check timing again with the belts off once it's all back together.

Update and solution.

After a lot of fault finding, turns out the timing belt needed to be removed and the crank spun one full rotation..... not sure how it got like that and I never thought I car would run and idle that far out of timing.

But now you know!

Reading this makes me wonder if the distributor was 180 degrees out and would spinning the distributor 180 degrees be an easier fix?

It’s a Baleno g16b

[Brenno]

Yup, as Steve said, no dizzy.
