engine turns but wont start what is the most common problem

Asked by for the 1992 Toyota 4Runner
Check for fuel, bridge B+ and FP in the black diagnostic socket box in the engine compartment that makes fuel pump run, check for spark at plugs and then check for mechanical integrity (compression engine components in synchronization. ).

For a mechanically good internal combustion engine needs the following things to run: fuel, air, ignition - in the right time. Lack of these could cause the no start condition.
I'd check spark first, than fuel pressure and go from there.
