2001 Audi A4 Crank but no start (No Spark)

5

Asked by May 22, 2017 at 05:27 PM about the 2001 Audi A4 1.8T quattro Sedan AWD

Question type: Maintenance & Repair

recently bought an Audi A4 with the 1.8T. Has had a cranking no start since
I purchased it. I was told that it broke a serpentine belt cause the AC locked
up. The previous own had the AC removed and a new belt installed however
a P0011 was thrown and then cleared.

Since I purchased I have:

- Replaced Cam Sensor
- Replaced Crank Sensor
- Replaced both ECM Relays
- Cleaned Battery Terminals
- Cleaned ALL Grounds
- Replaced all plugs
- Checked ALL fuses
- Checked Compression
- Checked Timing
- Checked Fuel pressure
- Disconnected battery for 5 minutes
- Unplugged and replugged in every sensor.
- Pulled codes (Recently got P0685)
- Replaced ECU (From an automatic)

I have fuel just no spark I have checked the harness all the way back to the
ECU it looked good. The no spark issue is what prompted me to change
crank and cam sensor. I did noticed that when cranking there is no output
by the MAF sensor however the MAP sensor is working.

I've officially ran out of ideas.


I found fuse 29 to only have 1volt on it.
