replaced the starter now it cranks but won't start I
also replaced the battery and the alternator this
past summer I'm at my wit's end with it I need help
I also checked all the fuses and relays
Check to see if your model has the cold start module if not there is a mult-function module that may be causing all the headache. Sounds like you replaced all the obvious stuff it might be. I would consider in you situation to verify with a scan the offending part since as you know it gets $$$. Good Luck!
