Heres a couple thoughts and a link that may help. If fuel is a question, spray starting fluid in the carb while cranking. Make sure your plugs are dry and clean. Carburetors are funny old animals that need attention and give headaches like you have.
If you mean cranking...
1. Lack of proper ignition key. 2. Automatic shifter in 'drive' or 'reverse'. 3. Battery disconnected or defective. 4. Defective crank sensor. 5. Defective starter motor or solenoid. 6. Seized engine. 7. Security system tripped.
I've seen all of the above while working in service.
If you mean cranks but won't start.
1. Spark. 2. Fuel.
I check spark first, less messy.
a short circuit somewhere
A car will not start if the gear selector is not aligned properly. Sometimes it is necessary to move the gear selector back and forth several times so that the alignment will be corrected and car will start.
A fuel pump on its way out will also cause a car to not start. Think crank crank crank crank crank (man my hand is cramping) crank crank crank crank...nothing.
If you are asking about what will keep a Grand Cherokee from starting the factory alarm will if you have changed the battery or if the Jeep has been sitting up for a while you do the same as if your alarm was sounding lock the doors unlock the drivers door with your key and try starting I have had to do this to mine after it had been sitting while I was rebuilding the front differential.
Unless your car is a diesel, they can certainly keep your car from starting if they're missing. They can also become fouled or badly worn, which, again, could keep your car from starting.
It really depends on how the alarm is wired into the car. If it is wired into the ignition system the yes it will keep the car from starting if triggered.
No. The engine starts the car.
Yes it can
Yes it could
Faukt in wiring
i have a 92 bonn. and my car wasnt starting and it turns out it WAS the crankshaft sensor and the harmonic balancer
It can, if it is the full factory alarm.
That won't keep the car from starting, but will keep the A/C compressor from running.
If water or oil is getting into a couple of cylinders, the plugs can be fouled and not sparking which can keep it from starting.
I have seen a faulty boost sensor keep the turbo from "kicking in" but it didn't stop the engine from starting.
Yes, a clogged fuel filter can keep your car from starting. It can also ruin your starter as you crank that starter over and over trying to start the vehicle.
Broken spark plug wires will keep almost any car from starting.
what would keep my car from starting after replacing the center port fule injecter
If you are referring to the valve cover gasket developing a leak, then, no..this wont keep the car from starting. If you are referring to the head gasket, then , yes...this could prevent the car from starting. Check the distributor cap gasket or o-ring. This could also keep the car from starting on rainy days or dewy mornings...Good luck!! ...BB
If you have immobilizer in your car, sure it will prevent your from starting.
Yes, there are sensors that need to be reset in order to complete the starting circuit.
No, a pulley will not keep a car from starting. A pulley is part of a wheel, and it is held on by an axle. There are many other components that go into this, but none of them have to do with the engine working.
