no crank

Make sure battery has a full charge and connections all good. Note diagram for starter motor. Does the starter motor crank the engine? The key has to be in crank position for the starter motor to crank the engine. If not check the wiring circuit, I see three fuses, check those. The neutral switch is also involved. You can use a digital multimeter across battery pots, everything off, the generic spec for a full charge is 12.6 volts. Leave leads touching battery posts, have helper turn key to crank, how does the voltage react? If the reading drops way down, that won't work and you need to try jumper cables or a jump box. If the reading doesn't drop at all or not much, you have an open circuit to starter motor. You can always test the starter motor itself?

battery is good tested that all fuses and relay are good and so is the neutral switch. and when i turn the key to start nothing happens and all this started after it stalled on me

ok i found what was the cause for the blown fuse. it was the camshaft sensor so i replaced it now the car rough is the computer says it detected a misfire. now i am being told that after replacing the camshaft sensor you have to have a mechanic do a relearn on it. is that true are is something else might be wrong with it
