93 Nissan Sentra will not start

Go over it, check the air filter, fuel filter, make sure your key isn`t bent. bent keys off set the chip and the car cant read it. next time take out the key and turn it around and try it again. let me know.

good day Sir, try to check the spark plugs and air filter, i hope this tips will help you.

inside the fuel pump which is inside the tank. its a complete unit. just changed one today

lOOK BEHIND THE GLOVE COMPARTMENT. Compartmet is probabily plastic and all you have to do is push in real hard to get them past dash board.

Might try changing out the fuel pressure sensor. Have you changed your fuel filter?

I had similar problems after getting my ECU replaced.
later i got a letter from nissan saying it was the wrong program they flashed on the ECU (think it was a maxima ECU they flashed into my sentra)
it only seemed to do it right after my car warmed up while i was slowing down (for a stop) but never cut out when i was at a complete stop.

you can call nissan to see if there are any recalls or updates for your ECU program (they should be free if there is)

if that does not work, or it cuts off while accelerating, try checking your fuel/air ratio, spark plugs, air filter, and fuel injectors. (a fuel filter can even cause cut-outs as well if it's seriously clogged, but it's usually hard to start as well)

kinda sounds like heat problems, check to make sure your temp gauge is working and see if this helps...
- when it cuts out on you, turn key all the way off, then turn it back to full on (but don't crank) this should let you rad. fan run without cranking your car. if this causes the wait time to be shorter before you can crank it again (less than an hour) then it's most likely a temp gauge, water pump, hose or even a belt.

try placing car in nuetral and then try starting or push shifter forward while starting! this is a common problem for nissan also make sure your foot is on the brake when starting. for someof them this is a safety feature

try puting shifter in nuetral , common nissan problem

First from the fuel tank in side the fuel tank there is filter remove the screws on the top where the fuel gauge fitted when you remove gauge you can see fillter that is one sometimes blocked.

Next if you check fuel filter it is ok, but nissan sunny has fuel filter inside the caburator where fitted fuel pipe from the fillter clean that filler.

ather thiing is check your connections any leak or loose.

if it cranks for a longer time than normal and than it starts, you my friend need a new fuel pump rebuild kit/pressure regulator inside the gas tank. what happens is that the fuel will go back into the gas tank instead of staying in the fuel line and everytime you turn the key, the pump has to pump fuel all the way to the injectors again to get the car started. So, long crank and than start means fuel pump rebuild kit/pressure regulator in tank.
