Replaced two oxygen sensors the crankshaft sensor, two cam position sensors and changed the oil and filter. Disconnected the battery completely before I started anything. When I finished, I connected everything and tried to start, and it just turned over. After second attempt it crank right up and ran quiet. Next day crank up again and was okay. Tried that evening and it won't start just turns over. Please help it's my first time doing this alone. Always watched and asked.

Hello, were you having codes for those sensors before replacing them? And does the Tachometer move while cranking? If you had codes what were the code numbers.

Here is a guide that will help with pulling codes if needed.

Some crank sensors are adjustable. They have to have a certain air gap or you'll experience these type symptoms.

When you installed the crank sensor was there an o ring with it as shown below? If not, it may not be the correct distance from the tone wheel.

Are you getting a check engine light? new codes?
