It will turn over all day long but it won't start so I doubt if bad connections are the problem as the starter works fine.
Oops. My bad. Back to hooked on Phonics.
Back to basics for engine not running but cranks.
Engine needs 3 things to run:
1) Fuel
2) Spark
3) Compression
You can likely disregard compression since it runs otherwise.
Before randomly replacing things you need to narrow down the other two.
When it won't start but cranks. Pull a spark plug and check whether it is sparking? If so, this is not the problem. If it is not sparking (when grounded properly - ask for details if you don't know how to do this) you can now focus your efforts on this area.
When it wont start but cranks - use a (short) shot of starting fluid down the throttle body. Does it cough / sputter / or run for a second? If so fuel system is your problem. If it is in the fuel system, there is a published troubleshooting guide for both L-jet and D-jet. Follow the published troubleshooting procedure. Per Bret's suggestion it could be vapor lock but this "trick" will help you firm up that theory.
Fixing vehicles is not about guess work but a logical progression of determining where the problem is.
