Question about 2000 Jeep Grand Cherokee
Ok here goes motor was hydro locked cleared out all water gave tune up usual bit now we got spark got fuel and got compression motor cranks away injectors are spraying but will not fire wont even fire with the usual aid of starting fluid any ideas on what the issue can be its the inline 6 btw sounds like the map but to expensive to test on a whim thanks
The ignition system on your car has to work in perfect concert with the rest of the engine. The goal is to ignite the fuel at exactly the right time so that the expanding gases can do the maximum amount of work. If the ignition system fires at the wrong time, power will fall and gas consumption and emissions can increase.
When the fuel/air mixture in the cylinder burns, the temperature rises and the fuel is converted to exhaust gas. This transformation causes the pressure in the cylinder to increase dramatically and forces the piston down.the spark should occur before the piston reaches the top of the compression stroke, so by the time the piston starts down into its power stroke the pressures are high enough to start producing useful work.
