2011 2.4 Auto
in January, daughter was driving to gym at dark-thirty in the morning, we'll call it +15deg F outside.
Had warmed it up before she left, drive about five miles, pulled up to a stoplight to turn left, boom. Engine quit.
I get there 20 minutes later, car starts, and immediately dies. Over & over & over.
I tow it to my shop, has 55psi fuel pressure, has spark, and is still doing the start/die thing.
Pull codes, it has a P0010 Intake cam actuator stored & not much else. I think it had a low voltage code in it, most likely from trying to crank it.
Charge the battery, start diagnosing. All I can find wrong with it is not a damn thing, until I try to pulse the injectors. When I get to #3, and crank the engine to build back fuel pressure, the sToOpiD thing starts, runs, idles, & purrs like a kitten.
So I put it all back together and walk away from it for a while. Come back later, start-die, start-die, start-die..
And it's throwing NO codes. it's simply flat slap plumb shutting down.
So out of desparation, I run to the local House of Recycled Auto Parts and grab a PCM out of a similar car.
Unhook the factory PCM, clip in the boneyard unit, NOW it won't fire at all. Just cranks.
OK, I figure, going to have to go to Chevy for a factory PCM & a flash..
Hook the OE PCM back up, boom. Car starts, runs, idles, purrs. And has for the last three months.
Until today. She's leaving school (college) coming home for the day, get to the end of the college driveway, ready to turn onto the main road, AAAaannnndd it quits again. Start-die, start-die, start-die.
I ante up $100 to have it towed from a county over, get it to the shop & off the wrecker, and it start-die, start-die, start-die.
Hook the scammer back up to it, the P0010 intake cam code is back, and decide to start by pulling the PCM.
Unhooked the PCM, stood there for a minute, hooked it back up, reached in, hit the key.. Vroom. purr, purr, purr, purr..
Dafuq is going on with this hoopty? Between the senior three of us, we have 100 years combined experience (30+ years each), and we're baffled.
WHAT could be goofing with a PCM like this?
