Your Jeep's start-stop function is an automated system that ensures your engine does not spend too much idling. It starts or stops your Jeep's engine depending on the driving conditions. For example, auto stop start will prevent your engine from running when you stop at a red light and start once the coast is clear. 3. Engine won’t start or fails. A broken timing chain will cause an engine to not start or fail while driving. If the belt is already broken, the engine won’t have enough compression to start. If it breaks or jumps while driving, the pistons will be damaged from contact with the valves. The valves themselves will bend and potentially ruin Yep, I tolerate it on my hybrid daily driver because it's just the way it is with hybrids, and unlike the Pentastar, the hybrid's gas engine is actually specifically designed for frequent stop/starts without causing excess wear and tear - also it's less annoying because the electric motor drives the car forward without any delay even before the gas engine has kicked back on, and there's zero • If the engine cranks but does not start, and the anti-theft light is not flashing, the fault is not likely in the push button start system. Check for fuel problems (bad fuel pump, fuel pump relay, plugged fuel filter, no gas in tank), ignition problems (like a bad crank sensor or ignition control module), or a mechanical problem (broken Registered. Apr 25, 2019. #3. You really risk hurting your load more than your generator when stopping under load. Bad stuff the load sees when the generator stops: Dropping frequency. Wonky voltage as the regulator tries to compensate for the dropping voltage while the frequency is dropping at the same time. Bad stuff the generator deals with Hard acceleration burns a ton of fuel (ok, maybe not for a Tesla) and places heavy load on drivetrain components. Full-force stops cause rapid wear to the brake pads and rotors. Resist the urge to Auto start is terrible for your engine, most wear occurs at starting when the pistons are not lubricate enough with the oil seating on the bottom of the engine. Think of how much you will save in fuel versus the price of a new engine or fixing the damaged one. Also if you have a turbo you will destroy it faster. Apart @hillsons answer, starting the engine frequently consumes a lot of electricity from your battery. The battery wears down much faster when it's often discharged and recharged again. I heard short battery life is a common issue in cars with automatic start/stop fuel saving mechanisms. 2LPOFq7.
