Had this problem before, but I was able to start, now it won't. It cranks OK. Had it check before for the battery and alternator and it passed the test. Test was done successfully for the fuel pump and starter. I was told by a mechanic that the problem is with the ECM (Computer) that needs to be replaced. Anyone had this problem before? and what was the fix?. (ECM price at the dealer is at $870 plus labor)

You say it cranks (turns over) but will not start?

Yes, that is correct.

Try replacing the fuel pump relay.. I had the same cranking but no start problem and I replaced the relay and all is fine...
