Engines
Fuel injection on all Chrysler engines is electronically controlled, sequential (one port at a time), and returnless (there is a fuel line going to the engine, but none returning - a system first used by Chrysler on the 1995 Neon). For more information on these engines, see our 3.7, 4.7, and Hemi pages.
