Reason I ask this question is because it seems most troubleshooting I see on this forum when dealing with anon-starting swap always ask the same question: Do you have all the necessary EWS parts from the donor car? |
I have not had a EWS unit go out of allignment with the DME and I've purchased many DME kits with the matching EWS and key.
The DME's INS is written to ROM in the EWS unit along with key codes. After the Key code is matched to EWS starter is enabled then DME sends a querry to EWS for a INS match, if the match is good you get fuel pump and spark from the DME. All this happens in a fraction of a second and if all match you have a running car.
Was the previous wiring in the car EWS-II also what issue to you have? No starter or cranking-over and no spark or fuel pump?
