Nissan Repair: 92 nissian stanza wont start, oil pressure switch, fuel injector service

Question
Car had a leak in the gas filler pipe when purchased.  Repaired, replaced fuel filter, had fuel injector service done.Car would turnover but not run for more than a couple of seconds,when the engine was hot.Had a sensor replaced (not sure which one).good for about a year, just had a tune up done (was running/idling rough), am now having the same problem.

Answer
Linda,

I would check the oil pressure switch to make sure it is good sinc eit sends a signal to the computer letting it know that the fuel pump should work.  If the oil pressure switch is defective the engine will cut off shortly after the engine starts.  Also, check the fuel pump relay to make sure it is good.  A good rule is to check the fuel pressure first.
