What causes an engine with low compression not to start?
An engine with low compression in one cylinder will present itself by having a misfire and running rough while no compression in all cylinders will cause the engine not to start. There are many different low compression symptoms which will cause the engine to run abnormally.
What causes an engine to misfire on all cylinders?
Low fuel pressure will cause a lean mixture in your engine which will result in misfires on all cylinders. If you have trouble codes for misfires on all cylinders, you will want to check your fuel pressure. 5. Injector Problem Another problem, which was more common five years ago, is injector problems.

What causes a car engine to operate smoothly?
For the car engine to operate smoothly there has to be the right amount of air and fuel mixture. This is compressed then ignited by the spark plugs. The resultant pressure moves the pistons and crankshaft. However, there instances you will experience low compression in one of the cylinders. This causes misfires and problems accelerating.
