You need to put a scanner on it and check for codes. Sounds like maybe either the crank or cam sensor is going south on you. I do not remeber whether your 2000 has both or just the cam sensor as my 02. If the ECM is not getting a signal it will not let the engine start. You need to scan it to see whats happening.

Thank you I was thinking possible crank sensor I have no access to scanner and can’t drive anywhere to get scanned maybe I’ll just grab one and install and hope for the best
