2007 CXP613 CRANKS, No start

Recommended Posts

MP8......No engine communication. Checked power wires to engine ecm and have 12 volts to both. Checked fuses in top of dash and by clutch pedal. Other ecu's seem to be communicating. I have read where the fuse boxes go bad. Which one's are they talking about? And what are the sympton's?

1.  I know nothing about electronic engines.

2.  Crank sensor may be junk?

3.  Engine harness junk?

4.  Other codes displayed?
