If the customer is doing the swap themselves, I don't think the seller should even need to give out info. Swapping out fuel rails is the honorable thing to do, but sitting on the phone all day giving out tips is rediculous.

By the way, $5 says that your problem is related to the CAS. If the CAS signal doesn't make it to the ECU for whatever reason (like the connector isn't on all the way), the injectors will NEVER fire. Post up and let us know if this is the problem.
