Engine Performance problem
1997 Nissan Sentra 4 cyl Front Wheel Drive Manual 160k miles

I just returned from a trip and tried to start my Sentra after it had been sitting for about 10 days and it wouldn't start. The starter turns but the engine never fully turns over. I replaced the spark plugs and distributor cap and they are working just fine. I also replaced the fuel filter and checked out the fuel pump which is also working properly. The ECM doesn't register any sensor malfunctions. Air flow seems to be fine.
My assumption is a fuel injector problem but I can't see how they could all fail at the same time? Any ideas?
Do you

Hi doolerj, Welcome to 2carpros and TY for the donation

Do below and get back with some testing results we start here

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it

Thanks for getting back to me so fast.
The spark plugs are getting spark. Checked the pressure on the fuel line and it is within the recommended specs, so it is not the fuel pump or pressure regulator.
I think it might be a problem with the fuel injectors, as I tried to turn over the engine for a good 30-60 seconds and even gave it some throttle, and the spark plugs, while smelling like gas, weren't wet as I would have assumed would have occurred had proper fuel been getting into the cylinder.
The fuse for the injectors is fine, however. Is there any other sensor that controls the injectors?

Get a noid lite and hook it up to the injector harness and check if it flashes-if it does test the injector if not check injector ground circuit
