So I was driving and pulled to a stop light and the engine died, restarted and drove for a mile or so again to another stop and the engine died again, this time when it retired it was backfiring and running rough. Pulled over and it died again, when I tried to restart the starter would spin but not engage.
Replaced the battery and everything seems to work, lights gauges, etc but the starter will not spin. Read the codes and see a U0100 lost Coms with ECM/PCM A.
Checked all the fuses under the hood (in the fuse box) and everything having enough to do with the starter and ECM is fine.
When I attempt to start it I get the following, Service ESC / Service Traction and the little ESC warning light is on.
Alldatadiy.com was pretty dismissive when I informed them of the issue, and refused to respond when I asked if they could contact thier sources, I even offered to provide my vin to help.
I worked for a company that used OE data, it's impossible for them to, on a whim, "contact their sources". It takes weeks if not months usually to get an answer back for a question. It used to take us over a week to get a response from Ford on part number issues (and we were the part catalog for over 75% of their dealers!!). I'm not saying Aldata hasn't contacted them, if they have, you might not get an answer for a week or two...and they won't let you know anything in the mean time.
Ghost, and that's fine and I understand that, what gets under my skin is attitude. Just say sorry, can't help you as you just very ellaquently put it, that's all.
I finally gave up on Saturday, I thank everyone for their help (especially JohnWR, Ghost, Raygun). I figure either I missed something or it's the ECM. I spent Sat / Sun looking for someone that could bench test it.
Dealer wanted
$100+ to check it but he can't bench test if so I'd have to deliver the car to him, ($50 ish to truck it)
$400+ for a new ECM
Probably 1 hr to install it at $100+.
And that's assuming that it is the ECM and they don't spend a lot of time replacing parts until they find it.
So I was looking at maybe $650 or more if I let the dealer do it.
I finally found a company an hour drive from me that rebuilds all sort of auto electrical and electronics. If they can't find or fix the problem it will still be cheaper than the dealer and they suggest I will have it back by the Friday, the dealer wouldn't even look at it until Thursday or Friday.
Those ECMs will have to be taken somewhere, whether a dealer of a well-equipped shop, to be programmed with the vehicle's VIN. That will cost between $50 and $200.
The next step really should be to get a scanner plugged in to it to find out what the problem really is.
It'll also have to be flashed with the correct VIN and OS for the car.
I'd call Performance Autowerks. I'm sure Dave can get you the ECM, flashed, for less than the Summit ECM + programming will cost.
If you have a friend with HP Tuners, they can also flash it for you, with the correct VIN, for the cost of two credits. (Around $100 if memory serves.)
Just spoke with Summit again and asked specifically if I did need to have it flashed or not and was assured that as far as he knew it is "Plug and Play" as advertised which he described as "disconnect the battery, take it out of the box and install, reconnect the battery, go thru the key learning step start it and drive away with a big smile on my face".
Going to be mighty upset if I have to get towed to the dealer to get the ECM flashed.
That is concerning. Are the codes in the screenshot all that are present? Do they all come back if you clear them?
Also, wild guess: did Summit ask for your VIN? And did you have the P1682 before the new ECM?
Many cars will crank but not start even with a missing or bad ECM. (It’ll turn over, but won’t get spark or fuel.) I can’t confirm that for the Solstice, though.
There are a few YouTube videos on P1682. The Malibu uses the same engine as the NA. I would expect the same diagnostic method to apply to the GXP.
The fact that the u0100 is gone supports the theory that the ECM was the underlying issue. Crank relearn won’t keep the car from cranking and starting.
The “ECM not programmed” error seems pretty cut and dry. I’d call and raise a... fuss with Summit to start. Unfortunately, there’s no good way to verify that it’s been flashed without the use of HPT or a Tech 2.
Actually: can you see the temp sensor, MAF, etc. output in your scanner?
EDIT: Guess someone should "change" the codes on the forum that are provided....I found this on the list of OBDII codes. Thus the reason I asked the "unrelated" question earlier....
I also have a set of codes that I found on the web from when I first bought my car...guess they used the same source!! LMAO
I'm showing this as the meaning of code P1682 - Metering Oil Pump Malfunction
