Dear community,

After a long journey I found out that the MAF kept shorting out my F1 fuse on my VVT build. After disconnecting it, the car started right up. However there was no tach. So I tought I had to install the tach output jumper on the MS. After trying to start rhe car again no luck at all. I lost the crank signal and the cam signal so the car will do nothing anymore except cranking. And the TPS works fine aswell. I do get the required voltages over F1 and F2 on the ms3 board and both the cam and the crank sensor recieve 12 volts. After removing the jumper still no signals. How can I solve this issue ?

Thanks in advance and Kind regards,
Cedric

Check the wiring where you spliced the CKP and CMP sensors to the stock harness.
