Nissan Sentra 2 year 98 drowns in the game

Hello friends. First that nothing gives you my greetings. Well my problem is the following I have a Nissan Sentra 2 year 98 that is giving me a big problem what happens is that from a while for another the car did not want to leave, I made it check for the mechanic and the mechanic told me that the teeth of the distribution pine nuts were broken and the car had the lost point, it was taken out of the valves, the valves were changed to the chain of distribution. But it turns out that when the car starts, the car is for three seconds and the engine is drowned and not part. The car has the good point has a spark, it has the ignition module in very good condition, the distributor is very good fuel pressure and a good compression. But still the failure persists, I start and keep for two or three seconds and stop drowning in gasoline

I don't have Nissan. But it is supposed to have a fuel return pipe to the pond. Check that you don't get covered, I hope it serves you

We are going to check the pressure regulator and pipes thanks for your help and communicate as you walk.

Some data are missing, to precisely an answer
if this engine is injected, try that the catalyst is not covered, remove the oxygen sensor and try to do it without this if it part can be sure that the catalyst is covered, I hope I have collaborated

Thanks my friend. The engine is of electronic injection and the catalytic tests have already been done and the same thing happens, the problem is that it scans and sends me code 55 which indicates that the system is in order, but I understand that this car some scanner does not read all the sensors. What I have left to do is a diagnostic car on board but I do not have the scheme to be able to bridge the pins of the diagnostic taking, to read the codes, if someone had them Selo would appreciate. Diagnosis takes 14 pins
