So I've got a 91 240sx hatch, and the damn thing won't start lol. It has been sitting for about a year, ran just fine when parked. I tried everything I can think of. New fuel, fuel filter, plugs. Plugs smell like gas and fuel is getting to injectors. Has spark on all 4. Cap and rotor are obviously fine. A few other things I can't remember. If anyone has a few suggestions I could try it would be much appreciated. Thanks all

Check your power and ground wires, a bad ground can prevent a start. Does it crank? I mean, your starter is good and strong? Dash, lights and Check Engine Light all work normally?

You can get a good amount of results if you type "240sx start" into Search and check the box to only search topic titles.

How do you know you have sparks? Do you get explosion and exhaust while it's cranking but it won't hold as soon as you let the key go? Maybe you have a spark testor? I've had mine be really really hard to start after sitting for a couple of months, but I just kept trying and eventually it went. I never got to the point of smelling gas. What some people do when the plugs are all wet, is to pull the fuse for the fuel pump. Crank it a bit to clear out the extra gas, the put the fuse back and try some more. You don't have anything unplugged do you? Like the MAF or distributor or something stupid? Rats nest in the intake box maybe? fuel, spark, air... Did you check your air path? If there is nest, be sure to share a photo!
