Help with retrieved trouble codes
Hello friends,
This problem regards a no-start that has evolved to these latest trouble codes I just retrieved. The background can be found at this thread: How much fuel pressure at injectors? I changed the spark plugs and surprisingly got the engine to start. Now it sometimes will start when warm, sometimes not.. will always start cold after long crank. Once started it idles perfectly OK, but will die if I punch it ... once up to above 1k rpm's it runs fine. Here are the trouble codes retrieved: -TNA (RPM) signal -Road speed signal at CIS-E unit -Data exchange fault between CIS-E control unit and EZL ignition control unit Any help interpreting these codes would be tremendously appreciated. Thanks in advance

Hi Paul,
Wiring harness? EZL to CIS-E signal loss leads me to that conclusion. Best, |
