this is free.i make nothing from this.so.1 can of easystart availiable at fuel stations everywhere.remove air filter and spray a SMALL amount in intake duct.easystart is highly volotile and will start and run a motor with no carb or fuel pump if diesel.the idea is if the motor runs on it then all the mechanical internals must be ok.if it will not run 4 cyls then something is wrong inside,yes.so if it will not run 4cyls on easy start and the fuel system is discounted,it has to be internal.process of elimination.standard tests:1black smoke?burning incomplete fuel.2blue smoke,burning engine oil.3white smoke?trying to burn water/coolant.ur are under no obligation to trust me and i understand if u dont but ur options are limited at this point.it dont run.all 3 of mine do with no complaints.
