Okay, we changed spark plugs wires and on the right side my wires is on wrong. It cranks but starter makes a noise while cranking and also turns over a few times before starting. I know this is wrong cause until we replaced them it cranked fine no noise or anything. My wires does not have numbers but we started out like instructions to do but the last 3 on the right is wrong. Accidentally removed that side before marking or one by one. Can you help tell me how to fix this? I have 1 wire that's longer than the other 2 then one is just a little shorter than the last one. I have the firing diagram I just don't know what wire is which.

You don't need to worry about the length of the wiring as much as making sure they reach the plug and the coil. Then you need to make sure they are going from the coil position to the corresponding cylinder. I attached the diagram you need to check this.

As for the starter making a noise now, I am not sure that is related but can you get a recording of the noise and we can try to determine what it is?

Thanks
