Not too sure what you mean by error code 6, here's a manual of the diagnostic codes for elaboration:

Hope this helps! :thmbup:

Thank you. Yes I followed the diagnostic guide and code 6 is what came up, (no NE signal to ECM). I use the manual to attempt to diagnose the issue. When I checked the ECM, I found that I had a voltage reading of 2.2 volts between the corresponding terminals. The manual indicates that the voltage should be between 0.7 to 1.4 volts. I went ahead and ordered a new ECM.

The van will start but in order to keep it running I need to keep the rpm above 1500.

I checked all the visible connections and they all look ok.

if anyone else has any experience with code 6 I’ll take suggestions.
