Lexus es300 tries to start but won't run?

Question

fuel pressure start position. no fuel pressure in run position

Answer 1

either what the first guy said or check the distributor because my camry was doing this it would start but die when it was put in gear and the distributor was the problem.

Answer 2

possible main fuel relay issue.  How old is your vehicle and how many miles.  If over 100K, I'd say fuel relay is the first check point.
