probably your battery is out of specs. you need to be able to measure
12.45 to 12.65 volts when engine is off. lower voltages are not enough
for modern cars.
probably your battery cant conform minimum requirements of digital circuits used to drive starter motor in high tech cars. that is why it works only with external charger. measure your abttery. it should be showing at least 12.4 volts. normally battery should show 12.5. to 12.65 volts. probably your battery has sulfation. end of its life.
Either replace the washer bottle or pull the pump and replace the pump some cases has had a pump leaking around the seal or a cracked pump due to adding water in the fluid bottle, never add water it will freeze and pop the pump
It sounds like you're experiencing a significant issue with your Maserati Biturbo. Gas pooling on top of the intake manifold can indeed cause rough running and stalling problems. Here are some steps you can take to address this issue:
Check for Leaks: Inspect all the fuel lines, hoses, and connections for any signs of leaks. Make sure that there are no cracks, loose fittings, or worn-out seals that could be allowing fuel to escape.
Inspect the Carburetor: Check the carburetor itself for any signs of damage or wear. Ensure that the float level is correctly adjusted, as an incorrect setting can lead to fuel overflow.
Check the Fuel Pressure Regulator: The fuel pressure regulator is responsible for maintaining a consistent pressure in the fuel system. If it's faulty, it can cause excess fuel to be delivered to the carburetor, leading to pooling.
Examine the Float Valve: The float valve in the carburetor is responsible for controlling the flow of fuel into the carburetor bowl. If it's stuck or damaged, it can lead to excessive fuel delivery.
Inspect the Needle and Seat: The needle and seat regulate the flow of fuel into the carburetor. If either is worn or damaged, it can lead to excessive fuel entering the carburetor.
Check the Choke: Ensure that the choke is operating correctly. If it's stuck in the closed position, it can lead to an overly rich mixture, causing fuel pooling.
Clean the Carburetor: If you find any evidence of dirt or debris in the carburetor, clean it thoroughly. Use carburetor cleaner and compressed air to remove any obstructions.
Verify the Ignition System: While this issue seems related to fuel, it's also worth checking the ignition system. Faulty ignition components can lead to similar symptoms.
If you're not experienced with carbureted engines, it might be best to consult a professional mechanic. They will have the expertise and tools to diagnose and repair the issue. Thank You.
no vin or country told.
no engine told ! guess
4.2 L Ferrari/Maserati F136 R V8
just a year.
it can only be 2 places.
on the radiator top side direct or indrectly
or the car has RAD top side resivour. that is under full pressure of RAD, not the overflow side tank.
we are not any kind of Maserati forum.
best is find a real forum or buy the service manual for it.
or go to any auto repair shop drive in , hood
up and ask.
easy no, any tech that can see the engine
can answer, all can. (or run)
got IMMO?,. (security Immobilizer) << for engine.
got 2 keys, lost the spare, that came new with car?hummmmmm
if yes, the cluster (IP) has lamp that is IMMO lamp(status)
if it glows wrong IMMO is bad or the key is bad.
the users guide in the glove box covers all this, Lamp actions told.
cranks fast but does not start?
or does not crank at all, <<<<< not told yet.
most IMMO cut fuel, but not all, and no such cars here.
jumper cable start the car,, off running car.
new batteries must be fully charged, not guess at we test them.
rested, battery is 12.6vdc not blew or we charge it now.
or jump start car.
key stuck
https://youtu.be/cpaEnvx7JCo
never have just 1key for any car modern.
do not have both keys in hand same time inside car, as some cause a war with the IMMO. keep 2nd key 25feet away 10 meters.
then swap them keeping distance there or more.
If you can access the interior you can inject some power via the cigar lighter/power socket.
If you can open the bonnet/hood there will be a number of electrical pathways to the battery available - the best being the main supply to the starter motor/solenoid.
If the car is completely locked it should be possible to access the starter from the underside, though likely the undertray would have to be removed.
I assume the battery is in the boot?
It should be possible to partially power the vehicle via the cigar lighter or socket if you don't want to dirty your hands. In theory it could be possible to charge the vehicle battery that way (trickle charging with precautions).
It should be possible to access main battery points for jump starting in the engine compartment if you have a rough idea of what you are doing. Some manufacturers provide a facility but the starter motor is where the main battery cable terminates.
