Car not starting. Code p0650 still present
« on: 22 May 2017, 20:03:29 »
Hi folks wondering if anyone can help with the above.

Had been using the car so it was hot. I had switched engine off, but when I tried to restart the car it turned over but wouldn't start. I played around with the starter motor turning and switching between petrol and gas and the car finally started. I think I may have managed to start it on gas. The car ran fine. As soon as I turned it off it wouldn't start again.

Have used "My Naff Code Reader" on it and the following codes showed.

P0650 (4) unknown present
P0430 (1) unknown present
P0420 (1) unknown not present
P1612 (0) unknown not present

cleared faults and attempted to start again with no luck.

P0650 showed up again.

This is listed as:

P0650 Malfunction Indicator (MI) Control Circuit High Instrument
P0650 Malfunction Indicator (MI) Control Circuit Low Instrument
P0650 Malfunction Indicator (MI) Control Circuit Open Instrument

Anyone know what this is?

Cheers

Over 1/4 full tank. Funily enough I had only just put a bit more fuel in......surely not the reason? Duff fuel? Yes EML was removed by previous owner after LPG instal as it was continually on.

P1612 Immobiliser No Or Wrong Signal Immobiliser

This code had been generated but was no longer present. It didn't get regenerated once cleared. I could understand why the car wont start if there was an issue here

Which means the LPG installation is sub-standard and could (potentially) cause engine problems.  ::)

As for the current problem, I'd put my 2p on Crank Sensor failing :-X

Wouldn't that generate a code?

Crank sensor was replaced a couple years ago. Probably only about 10k done since.

Just googled car not starting after refuel.

Found this regarding a vectra: Check the condition of your petrol filter under the rear drivers side wheel, if its rusty its probably got a slight leak and when you open the fuel cap you cause a air lock.

Will check it tomorrow. I guess a mechanical problem like this wouldn't generate a code but I would have thought I'd be able to smell fuel?

My money would be on crank sensor too.When you replaced yours a while back did you use genuine GM? or A.N.Other? I believe crank sensor failure doesn't always throw a code,others may be able to advise better on that.

Agreed re crank sensor, although as LD suggests, lpg install being less than great could point to other issues.

If an estate, put another 2 gallons in and retry :y

It's easier to check fuel feed by removing the feed pipe at manifold, then having wife crank engine while you point the pipe into a jar.
Is it possible you put in diesel, not petrol?

I think I did this and yes it was running okay until I turned it off again. How do you false start on LPG so I can try that again? The system is stag 300 plus.
I think as it was running okay on gas that maybe the crank sensor is okay.
I have been reading that LPG cars sometimes get a petrol pump failure due to running around with 1/4 tank of fuel.
New filter ordered and can get a new pump for £20 if necessary.
