SIGNS OF A BAD FUEL PUMP MODULE DRIVER
Another common issue you may face due to a bad fuel pump driver module is No Start. We need to keep our vehicles idle quite often. Stalling or Uneven running while Rough idling. I'm going to try Archoil one of these days. What are the symptoms of a bad fuel control module 1. I don't notice any super duper performance gains, but pulling out water and lubing the HPFP gives me peace of mind. It also is supposed to help lubricate the HPFP and boost cetane.

Everybody has their own opinion has their own opinion on additives, but yes Stanadyne is my choice.
