Default Stranded!

Hi, all.
I was pulling into a parking lot. My engine died suddenly, not coughing, etc. Then it would crank but not start. Had it towed to a nearby shop (not a dealer). They read codes B2562 and B2607. I had bypassed the steering lock module about 2 years ago, and no issues since.

1st question: shouldn't a steering lock module issue (B2607) prevent cranking?

B2562 is low voltage to the BCM. Could this cause a no-start?

Any ideas welcome.

Check the battery's condition.
Whilst you have the battery disconnected, step on the brake pedal to drain all power from ECM.
Hook up a good battery and give it a try. Engine may run rough for a bit, while ECM is relearning.
Check for any DTCs. An OBD reader can be purchased for less than $50 or most auto parts stores will lend/rent you one (some will even walk out into the parking lot and read DTCs for you).

Thanks. The battery did drain fast after it died and I was cranking it to try and restart. But it DID crank vigorously a few times before slowing down. The shop is supposedly charging and testing it now. 1st thing they wanted to to was replace the steering lock module. I said it was bypassed, and asked them to dig deeper before throwing a $1000 part at it. It was running when it failed, and allowed me to crank the engine. Does not sound like the steering lock module. Then they thought it was my key. wanted me to bring my backup key. I said, again, it was running. I can stomp the key into dust while it is running and it will keep running. They insisted, so i took them the key. Of course it didn't work. No "Key" icon while cranking. The battery was flat at that point. That's where I left it. You are right, I should have had it towed home. The said it has spark. If true, then cam and crank sensors should be OK. Maybe the fuel pump failed. Or, like you said, maybe just a failing battery....

Buy/borrow/rent an OBD reader and get the codes yourself. Cars have gotten very good at self-diagnosis.

I agree that the problem is not the ESCL - car wouldn't try to start if it were bad. Same for fob.

My money is still on a bad battery; possibly the charging system.

Sounds to be a possible issue in your charging system. It may be a bad battery and/or alternator. The fall/winter season is hard on all vehicle charging systems.

They finally diagnosed it as a failed fuel pump (36 hours after I suggested that they check it). The low voltage code was from running the battery down cranking it fruitlessly. The steering lock code is from me pulling the fuse so long ago I forgot I did it.

So then they called and said "this thing has an aftermarket fuel pump, and the factory wiring has been altered (true, I put in a CJM hat a few years ago. Forgot it involved changing the connector). We can't replace it with am OEM module. Come get it and have it towed to a dealer to have the wiring fixed. You don't owe us anything, just pick up the keys."

So, I'm waiting for a call back from the towing company to have it towed home.

Final report. Wire came off the fuel pump motor and shorted to ground. Pump fuse was blown. Squeezed the quick-connects with pliers to tighten them up, reinstalled, replaced the fuse, she's running fine. Cost = 2 tows, about $200 and a few hours of my time. Next time I'll have it towed home.
