2006 Spectra crank but no start
Hoping to get some help fixing my sons Spectra. 2006 manual trans with a 2.0 DOHC engine. This is a very long post but I tried to include all the information I could.
Here is how it all started.
Bought the car used, when I received the car there were a couple of stored codes. My code scanner does not read SRS codes so my son borrowed one from work (AutoZone) The codes I got were:
P2237 o2 sensor positive current control circuit open bank 1 sensor 1
P0016 Crankshaft position - camshaft position correlation bank 1 sensor A
P0030 HO2S heater control circuit bank 1 sensor 1
And a fourth code that was an SRS code which indicated the passenger seat occupancy indicator was bad. Bought a sensor from the local pick a part and the SRS light went off.
My son calls the other night and said that his car is overheating and the alternator light is on and he is at a gas station. I go check out the car and the belt that runs the alternator and the water pump is broken. The broken belt was caused by the alternator mounting bolt - Goes through the tensioner and locks the alternator in place after tightening the belt - was broken. Went to the local parts store bought a new belt and new bolt and everything was fine. Disconnected battery before messing with remounting alternator.
A day or two goes by and my son says that his alternator light is back on, but he checked the belt and everything is still good. So he runs the code while at work and it comes back as the alternator voltage regulator out of spec. He didn't actually give me the P code just what the text was.
The following day he calls me and says he can't make it home because his battery is dead. He had his headlights on and ac on which was enough draw to drain the battery down and cause it to stall. Went to get him, removed his battery installed a fully charged battery that would allow him to drive the car home. which he did.
So we make another trip to the local pick a part and get an alternator and while we are there we grab a camshaft positioning sensor and a crankshaft positioning sensor. Come home remove the battery that was installed temporarily to get him home, Change the alternator and the two positioning sensors and fire the car up. Everything seems fine the alternator light is off, so at this point we feel we have got a small win.
The following day on his way to work he said that his check engine light had gone off as well. At this point were feeling pretty good that one of the sensors fixed the P0016 code. He takes his car to go to lunch drives about 3 miles from work and it just dies at a stop light, It cranks but will not start, that's where we are today.
What I have done so far to troubleshoot this problem.
Removed the air intake and shot it with starter fluid and cranked engine - nothing - eliminate fuel system
Remove spark plug and test for spark. NO spark. Ohm out coil packs. Good. check wire going to coil packs 3 wire version can't find the correct wiring schematic but one of them should supply 12v with ignition on. Nothing. checked all the fuses that I could find that said anything about ignition or ecu. All good. switch main power relay. no change. Prob the slave side of the relay to ensure it is clicking. works fine. Probe the power distribution box to check for power and ground. Power is on both the high and low side of the relay but i do not get a ground when the ignition is in the on position and the relay dose not click. Installed the original cam and crank sensors just to eliminate any problem from them. No change.
Install my scanner tool and tried to connect several times and tool will not connect with car.
Had my son bring home a scanner from work and tried to connect several times and it will not connect.
Disconnect battery and remove ecu. open up ecu and inspect for any physical damage. None present.
If someone could please provide me with a proper troubleshooting guide, some personal experience or even a wire diagram that is actually for a 2006 DOHC 2.0 spectra that would be great.
