240sx wont start

[1Lazy40]

Hello zilvia my name is torey i have had my 91 240sx super hicas for about a year now, with onl1 1 prob it would smoke a little from time to time and that it would run funny after inwould drive it fast. It would idle funny and sound like a wrx, i think it was an injector prob, but other then that it would drive fine , but the other night after driving it for about 20 min , and then turning it off , it wouldent trun back on , it starts and runs fror about 2 sec then shuts off, i looked over my fuses and i noticed my fuel pump fuse was blown so i replaced it , but still had the same prob , i then removed the fuel pume it self it looked ok, i wired it to the battery to it seem to be working fine , i have no idea why it wont run , anyone else had this prob or know what it could be ?

Pinched fuel line? Possibly clogged injectors. I would pull out the injectors and make sure that there isn't any build up that may be blocking them.

Ill look and see how the lines are , and when i try to give it gas while its on for the 2sec it does not seem like its getting gas

check your fuel pump grounds, one in the trunk right under the latch, and check the ground above your fuse box inside the engine bay on the left strut tower

My buddy had the same problem. Took me awhile to figure out but it ended up be bad injectors o rings causing the car to flood itself out which kept it from starting. Replaced all the o rings and now runs great.

Have you checked your fuel filter yet? It could be clogged forcing back pressure to blow the fuse on the pump. Replace your injectors but check your fuel lines both feed and return.

They should be the same. Just make sure you replace all o rings when you have them out.

Just changed the injectors this morning with new o rings, and it started right up good as new :), o and i replaced the fuel filter (z32) like u said hardtime21 when i took it out thick black stuff came out of it, i bet that was the main prob , but yep my 240 is good as new thanx guys :)
