i tested the 2 circuit breaker i found electricity and they are okay. i have continuity with my ohm tester , the cluster is working all over sudden , don't know what i did , only cleaned the relays inside. i ran the code reader the only reading is P0753 don't know what that means.but the yellow key appears but no check engine light. i broke the flasher relay by pulling it , still not start.

Whenever I turn the key at normal speed in the vehicle does not start. t however, if I slowly turn the key into position it starts up no problem. I checked the relay and it’s not relay. What could this be?

Good afternoon.

Relay? what relay?

If it has to do with the key then good chance it is the ignition switch itself.

Can you upload a video of what happens?

Are you sure you're hearing the starter relay click? The automatic shutdown (ASD) relay will be clicking too. The crankshaft position sensor has nothing to do with the starting system.

A common problem is the neutral safety switch. You might try bypassing the starter relay to verify the rest of the system works. Do that by removing the cover from the starter relay, installing it that way, then squeezing the movable contact, or you can use a piece of wire or stretched out paper clip to connect terminals 30 and 87 in the socket.
