S80 No start condition ECM 3000 and 3010

[Mark27]

While fixing my thermostat housing nipple, I decided to change the timing belt/tensioner/idler pulley on my 03 s80 T6. During the housing repair I removed the intake VVT solenoid in order to facilitate the removing/installing thermostat housing cable. I also disconnected the two VVT solenoid connectors, for space purposes. I then removed and replaced the timing belt and accessories. After all repairs, I started the engine. Everything seemed normal for about a minute or two, and then I noticed the engine started to idle rough. The check engine light illuminated and a timing camshaft code appeared (cannot recall the codes). I adjusted the cam gears and restarted the car. Again the check engine light illuminated and the car idled roughly. I did not read the codes because it was late so I assumed it was the same as last time. Because I used water as a temporary coolant, I decided to drain the system because of freezing concerns. That’s when I noticed a pool of oil near the left side of the drain cock (near the transmission pan/under engine). After investigating, it appears the oil came from the VVT solenoid I removed and channeled to the left side of the car (car was jacked on the right side to remove Rt wheel). The next day I tried to start the car and it cranks but no start. The codes are ECM 3000 and ECM 3010. I checked the VVT fuse because the wires right after the connector where stripped of insulation and may have touched. I also should note I had to wiggled the ECM/TCM housing back a bit for room purposes but they were not removed. I checked the ignition coils, and it appears the oil leak did not impact that area. I also checked the fuel line, there was pressure. I hope I didn’t ruin the valves but if I did would that make for a no start condition? Not to mention, the car started and idled the day before. I had an extra cam position sensor that I exchanged, still no start and the same codes. Also could reversing the intake /exhaust VVT connectors cause this to happen? Any idea will help?

These codes mean different thing for the 5 cylinder and the 6 cylinder. Which one do you have?

I worked it out, you have the ECM-3010, 2003 S80 5 cylinder did not use ECM-3010.

On 2003 S80 with the 6 cylinder:
ECM-3000 covers the intake camshaft position (CMP) sensor.
ECM-3010 covers the exhaust camshaft position (CMP) sensor.

Did you get the two reversed?

Possible sources

Signal too high:

• Open-circuit in the signal cable
  Short-circuit to supply voltage in the signal cable
  Short-circuit to ground in the power cable
  Open-circuit in the ground lead
  Defective camshaft position (CMP) sensor.

Signal too low:

• Short-circuit to ground in the signal cable
  Open-circuit in the power cable
  Loose connections.

Signal missing:

• The camshaft position (CMP) sensor is in the wrong position
  Defective camshaft position (CMP) sensor
  Loose connections.

Faulty signal:

• The camshaft position (CMP) sensor is in the wrong position
  Defective camshaft position (CMP) sensor
  Loose connections.

Fault symptom

• The engine is difficult to start.

Thank you for answering Rick. When I read the codes, I only interpreted the actual code number and did not further investigate why they were triggered (actually I do not think my reader is capable of further diagnosing anything other than the code number). I am going to attempt to work on the car this weekend, weather is a lot warmer in the Philly area, and I will reverse the connectors and hopefully that will solve it. I'll get back to ya this weekend.

Over the weekend when the weather was more conducive for troubleshooting, I removed all the ignition coils so i could inspect for an oil breach. I discovered cylinder 4 was 1/4 full of oil. I theorize, when I re-installed the VVT solenoid behind the intake sprocket it may have been too loose or the gasket was too old and brittle (read original post). And oil channeled over the cylinder and leaked into the well (I hope!!!). I removed all the spark plugs and they were pretty fouled so i replaced them. Some of the wires inside of the wire assembly that connects to the ignition coils had brittle and frayed installation covering that needs to be at the very least covered with electrical tape. I will complete the ignition coil wire assembly job this weekend. Hopefully that will fix it. Although I can't figure out why the camshaft codes 3000 and 3010 were triggered since the camshaft sensor had zero to do with my repairs.

Do you know for a fact EMC-3000 and EMC-3010 where not there before you started?

[Mark27]

Well Weather was good enough to finally look at my S80 and figure out why it isn't starting. After much research I located someone that went through a similar scenario, ECM codes 3000 and 3010 after timing belt change- a timing issue of course. It appears when I originally changed the belt, my intake and exhaust cams sprockets were off but the car was able to start and trigger a "timing off" code (I forget the codes). When I corrected the two cam positions, I neglected to also make certain the crankshaft sprocket was also aligned. That error threw the timing off so much, it triggered the two ECM codes 3000 and 3010 and a no start condition. Once I located the timing mark on the crankshaft sprocket (by the way, the PULLEY in front of the CRANKSHAFT MUST BE REMOVED in order to see this mark) and aligned it correctly the engine turned over.
