Can low compression cause no spark?
Misfiring can be caused by loss of spark; imbalanced air/fuel mixture; or loss of compression. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
Why does my Car start but no spark?
The engine is getting no fuel, the injectors are only getting 5.8V instead of 12V, and the ignition coil is getting no spark. All my research pointed towards the Crank Shaft Position sensor fixing this, especially since it was stalling a low speeds, and now has no spark or fuel injector pulse.
Why does my Car Crank but no engine?

If your spark plugs are not working properly or even dead, that will have a detrimental effect of your vehicle’s ability to start. Without that initial spark from the spark plugs in your vehicle’s engine the engine can’t receive the fuel or the compression to jumpstart the engine.
Is it OK to change the crank sensor?
No, before changing the crank sensor the RPM’s were at 300 to 400. After changing the sensor, tachometer is at 0 RPM’s while cranking. The crank sensor was testing as receiving the proper voltage. The sensor itself was testing as sending the proper voltage as well.
Do you have spark, fuel, compression but no start?
I have spark, I have compression, and I have fuel (I even tried spraying a little starting fluid in the carb). It turns over, but won’t start.

What should I do if my car cranks but no start?
All my research pointed towards the Crank Shaft Position sensor fixing this, especially since it was stalling a low speeds, and now has no spark or fuel injector pulse. The mechanic I’ve been working with the last 2 days wants to try replacing the Crank Shaft Angle Sensor/Trigger Plate/Crank Shaft Angle Plate, whatever it’s called.
