What is the Fuel Injector Firing order for a 1995 Chevy S10 Blazer 4.3 vortec ?
Country: United StatesMake: ChevroletModel: S10 BlazerYear: 1995Engine: 4.3 Vortec
The injector lines were all disconnected when I received the vehicle. Is there a specific firing order or is any order satisfactory ?
With this type system,(CPI) the order is not important, because all 6 poppet's are pressurized at the same time. Just route them to where they lie the best. Sometimes on the bottom of the "spider" assembly they are numbered. Below is a description of how this system works.
