Crank position sensor........going bad.....You didn't say what car it is..but.. some have two signals coming from it. 3x pulse and a 16x pulse. If either one of these pulses fail, your car wont fire right or not at all. It will still run if the cam sensor is a miss, though...
What else can I help you with?

Chek out the ignition coils, the wires and the spark plugs..
How do you fix cylinder misfires?
start with new plugs
What can because a missfire on a 1995 Pontiac firebird?
most misfires are caused by bad spark plugs, plugwires, coils, module, alternator or fuel injectors that need to be cleaned
2005 RX8 automatic with new plugs still misfires when accelerating but only at high RPMs right before shifting to next gear Why?
Most likely, the problem is the ignition coils, though it's a good idea to change the wires while you're in there.
What are the coils on a Mazda rx8?
The coils on a Mazda RX-8 refer to the ignition coils, which are essential components of the vehicle's ignition system. The RX-8 is equipped with a rotary engine, and each coil is responsible for igniting the air-fuel mixture in the combustion chamber. Proper functioning of these coils is crucial for optimal engine performance, fuel efficiency, and smooth operation. If ignition coils fail, it can lead to misfires, reduced power, and increased emissions.
What could cause random misfiring on a 1998 Lincoln Town Car?
When your check engine light comes on have it diagnosed and it will tell you which celinder is misfiring and you reolace tha coil.I would say ignition coils. I have a 1999 Licoln TC and must replace all 8 due to misfires as vehicle approches 100K miles. Remember also if you change your coils install new spark plugs!
What happens when a cylinder misfires?
When a cylinder misfires, it fails to ignite the air-fuel mixture properly, leading to a loss of power and efficiency in the engine. This can cause rough idling, increased emissions, and potential damage to the catalytic converter over time. Misfires can result from issues such as faulty spark plugs, ignition coils, or fuel injectors. Additionally, the engine's computer may trigger a check engine light to alert the driver to the problem.
What will cause the coils not to fire?
Coils may fail to fire due to several reasons, including insufficient power supply, a malfunctioning ignition system, or faulty wiring. Additionally, issues such as a defective coil or improper connections can prevent the coils from receiving the necessary signal to operate. Lastly, problems with the engine control unit (ECU) or sensor failures can also lead to coil misfires.
What cause misfires in Lincoln LS?
Usually that is caused by one or more compromised ignition coils. Common problem on the LS. Water migrates along wires through to the ignition coils that are just above the spark plugs. Water rusts and thus compromises ignition coils. Oil infiltrates through gasket and soaks coils thus compromising them. Problem is reputed to be occasional, but I have a feeling that this occurs all too often. Many if not ALL LS owners suffer through this.
Why does your 1999 Dodge Ram 1500 truck have misfires?
Misfires in a 1999 Dodge Ram 1500 can be caused by several factors, including faulty spark plugs, worn ignition coils, or a malfunctioning fuel injector. Additionally, issues with the fuel system, such as a clogged fuel filter or low fuel pressure, can contribute to misfires. Engine vacuum leaks and problems with the engine's timing can also lead to this issue. Regular maintenance and diagnostics can help identify and resolve the underlying causes.
When changing the coils there are no numbers on the new coils so how do you know that the coils are in the correct spot?
The first coil is on passenger side by firewall and then go from there.
Are there common problems with coils on a 1999 Mitsubishi Galant?
Yes, common problems with the ignition coils on a 1999 Mitsubishi Galant include misfires, reduced engine performance, and difficulty starting the engine. Over time, these coils can wear out due to heat and electrical stress, leading to inconsistent spark delivery. Additionally, faulty coils may trigger the check engine light, indicating a need for inspection or replacement. Regular maintenance can help identify issues before they lead to more severe engine problems.
