replaced fuel pump. great pressure now. Replaced plugs, wires, cap n rotor. cranks and wants to start but just wont. Timing is good. what else would it be? I dont get it. the crank n cam sensors are in the distributor so im told. Is there anything else I should try before changing the distributor out?
I have a 96 sentra that wont start on 1996 Nissan Sentra

Take off the distributor cap and see if the distributor is full of oil, it was a common problem with some of those Nissan. Using a mechanic's stethoscope (or use a long screw driver placing the handle end up to your ear place the metal tip end of the screwdriver against the body of the fuel injector), get a friend to crank over the engine while you "listen" to the fuel injector listen to each injector at the same point of the injector body. You should hear "click, click, click" as the injector is electrically opened and closed by the computer. If the injector is not being triggered you will not have fuel getting into the engine's cylinders. Disconnect the electrical connector at the fuel injector with the ignition key in the "on" position, (next position after the accessory position) you should have 12 volts at one of the two wires at the injector. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect....

aside of the fuel pump, plugs, wires, capn rotor, i have now eliminated the possibility of a bad distributor and bad compression. with #1 tdc, the timing all checks out perfectly. the distributor with the crank sensor is now new, and all it does is crank n almost wants to start. I was told it may be a mass air folw sensor or the computer. My scanner wont bring up any codes either.
everything has been checked firing, fuel,compression but it will not start it just backfires but never starts
