HHR LT w/2.4 Ecotec Starts but Doesn't Run
Hello - looking for some help if anyone has come across a similar problem.
2010 HHR LT with 2.4L Ecotec and 140K miles.
Pulled out into traffic and it stalled. Tried to start it and it will crank and start up, then in a second or two just stop (stall).
Got it towed home and thought it might be the fuel pump. Checked for DTC's and NONE are present.
Checked fuel pressure:
Key on: 56 psi.
Run (for 1 to 2 seconds before stalling): 60 psi.
60 seconds after stall: 50 psi.
2 minutes after stall: 48 psi.
I removed the air box & MAF sensor and cleaned the throttle body & blade and gave it a spray of starting fluid. It started and ran for maybe five seconds until the starting fluid was used up by the engine, then stalled again. Fuel pressure didn't change, 60 psi right after stalling. Set code P0102 MAF circuit low, since I had disconnected it.
All fuses and relays are good, battery is fully charged, Took the cover off the steering column to check the ignition switch connectors and they're seated.
Is it possible it's still the fuel pump? Will a bad crankshaft position sensor produce these symptoms?
Any clue from anyone? I don't want to start throwing parts at it without an idea of what it might be. Thank you!
