A dirty or clogged fuel filter is another reason for a car not accelerating like it’s supposed to when required to do so. With a dirty fuel filter, the engine won’t be getting enough fuel which means that the vehicle won’t be giving the acceleration performance that it should. Replace the fuel filter as soon as possible.
Ignition system issues – A weak or failing ignition coil can cause a no-start situation. Additionally, if the spark plugs or wires are worn, it may also result in the engine not starting. Fuses and relays – Check the fuse box for blown fuses or malfunctioning relays related to the ignition and fuel systems.
Letting the pump add pressure would ensure a perfect start each time. The smaller Fiesta engine (same series as the Puma) didn't seem to mind starting straight from OFF. As @Paulster2 noted, modern fuel-injected cars maintain pressure at the rail for a long time, both making starting quicker, and maintenance more time-consuming!
Have a diesel pajero swb that won't start first thing in the morning. Once it eventually kicks over it is fine for the rest of the day. Just had new glow plugs put it and still the same problem. If it gets started I can drive 500m, stop, and restart no problem. Anyone have any ideas what the problem could be! History of car. Car was great.
1. Weak Battery. If your Fiesta’s engine won’t crank or cranks very slowly, then the most likely culprit is a weak or dead 12v battery. Investigating more closely and doing a battery voltage test will clarify whether the starting problem is due to the battery. A test can be done to measure the voltage between the battery poles, check the
The average life of a starter motor is about 100,000 to 150,000 miles, and the life will be shortened if the engine is started more frequently. In any case, since the starter motor also has a limited life, it will break down after using the car for a long time, and if the starter motor breaks down, the engine will not start.
In cold weather, water can freeze inside the filter, causing a blockage. This can prevent fuel from reaching the engine, making it difficult to start. Another cause of blockage is a dirty or clogged filter. Over time, the filter can become clogged with debris, reducing fuel flow and causing the engine to struggle.
The key came on, things seemed normal, DRLs on etc, cranked fine, no security light, but it just wouldn't start. The only real telltale difference was the fuel gauge would remain on empty. The solution was to backfeed power into what GM called circuit 242 under the dash. It is a primary-ish power wire feeding the ignition from the underhood
The most common cause of the fuel system not holding pressure up to the injectors is the fuel pump inside the fuel tank. The fuel pump has a check valve built into it that is supposed to keep pressure to the injection system when you shut down and vehicle sits. If the pressure drops then the pump has to prime the system to bring the pressure
