Car drove fine, parked it and was gone 3 1/2 weeks on vacation. Come back and it cranks but will not start. Checked all fuses and even changed out main relay just because. No fuel on rail and no spark. Fuel pump works fine. Changed crankshaft position sensor. Still nothing. Reset security system 2 different ways. Still nothing. Car is fully charged. No idea what else can be done. Please help.

Welcome to 2CarPros.

I suspect there is an issue with the main relay. It is located in the under hood fuse/relay box. I attached three pics to help you locate it.

If there is another relay with the same part number, switch them. If there isn't, here is a link that shows how to test one:

Let me know if this helps.
