Hi before my car died I had had the computer run misfire in 2 and 3 and crankshaft sensor. I replaced ignition coil ,wires, and plugs. Also replaced the crankshaft sensor and battery. Tried auto start in the engine flange. Now my car won’t start. Is the a procedure I missed like crankshaft relearn etc.
Also, I caused an arc when I disconnected the battery could this have done something? Desperation after 5 days of trying to get it to start.

 

There is a funny thing about automobiles. the more you touch , the more can go wrong.

Because you did cause a non intended connection , there is always the possibility a fuse opened.
My first suggestion would be to check all the fuses. It sounds like a lot of trouble , but with a simple test light this can be done in less than a minute or two.

How about you get back to us after you verify all the fuses are good, OK ?
