1990 240sx hatch won't start

[KA Man Fu]

K so I and my friend he's a mechanic were sitting down tryying to figure out why my car wouldent start so already missing a 75 fuse I shoved romex wire in there as a subsitute it worked  drove it went to sleep came outside the next morning no start so we go at the car again we already did alot of work to it new fuel pump  new fuel relay  spark plugs spark plug wires distributor cap and rotor new fuses for fuel pump  all oil and fluids are new I let the car sit for 6 years before starting it  with Rome and start working on it I had a rotten fuel line so got new fuel line that's how I got the car to start so  I had bought a new fuel filter because it had a old 1  I had 6 year old gas in the car when I changed fuel filter do I pull filter in the morning thinking it can't be clogged cause the old gas and sure enough it was so I drained the gas  it was burgendy  and smelled horrible o yea I also had my friend use the thing you connect to fuses to drain the gas out my car cause it wouldent start  and for some reason it took us like 20 mins to get all the old bad fuel out cause we had to keep touching the fuse every 4 seconds so the gas would come out went and filled it with 91 changed to a 300zx fuel filter  and tryed it again sounded alot healthier  but still wouldent stay on at this point we had the battery charging with portable jump box and the fuse tester on my battery terminal all the lights were on inside the car  and outside

Okay, so periods and punctuation go a LONG way. Every time you type a sentence, say it in your head. If you have to take a breath, then it's time to use a comma or a period.

Aside from being a d!ck, let's try to figure this out. What do you hear when you turn the key - does the starter turn? Have you gotten your battery checked? Moving on. So you've refilled the tank. When you turn the key to 'on' (before turning your ignition to 'start'), can you hear the fuel pump prime? If so, work your way into the engine, and disconnect the fuel line right before the rail. Put a can or something on the end of the hose, and turn the key to 'on' again. If fuel comes pouring out, either 1) fuel isn't an issue, or 2) your issue is in your fuel rail/injectors. Let's assume it's number 1, or at least keep troubleshooting. If all is well with fuel, then it comes to ignition. One spark plug at a time, take it out, plug it into the wire, and then ground the plug against the body of the car. Turn your ignition on. If you see spark, that plug is good. Plug it back in, and move on to the next plug. Rinse, repeat for all 4. If your plugs check out (not a bad time to check your gap, but you said you just replaced that), let's keep moving. Are you sure you have the timing correct? The firing order is 1342, 1 being the front piston. The distribution cap is 1-2, then below that 3-4 (not numbered clockwise). How's your ignition relay (should be on the passenger side panel, next to/behind the battery)? Just a few first thoughts. You said you replaced (almost) all the ignition components in the engine. Have you checked your ignition coil? (The ignition coil is the pack that the center connector on your distribution cap connects to). A effed up distribution coil would keep you from starting too, but checking the plugs like I said earlier ought to tell you where to look. If you just replaced the plugs, wires, cap, and rotor, working your way back, the ignition coil is next.

If you've got a multimeter, it would make your life a TON easier to diagnose electrical gremlins.

I don't know about burgundy gas, but I'm going to assume it could mean rust in the tank. I don't know how gas ages, but if you've got rust in your tank, your attempts to start it may have carried rust through your prehistoric filter and into your injectors.

I'm not a mechanic, I just like figuring out how s*** works. I'm sure someone will come along with better advice, I'm just offering my 2 cents.

Something else that messed my car up was the Coolant Temp Sensor (CTS). It can cause the injectors to dump gas into the cylinders, giving you spark issues.

I appreciate all the help sorry for being a d!ck I appreciate the non flame. I'm very new and hi or drunk 75% of my day so I don't bother to check punctuation ok yes I would assume gas is burgendy cause it's rust but replaced the fuel filter. I pulled the line gas comes out and I hear the pump prime. So it could be a leaky injector bad o ring or fuel line crack/issue will check in one hour but my friend had said let's try to figure out this electrical gremlin to so I think the first post is gettig close to the money. Battery good starter good spark is no issue I get spark in all cylinders

Definitely check the wiring... I had similar issues with my '90 and it turned out to be worn out insulation on a wire in a wiring harness bundle. I traced the wiring from the fuse box in the engin compartment across the front of the radiator where it was rubbning up against a bracket. This was just to the left of the divers side popup headlamp. a little electrical tape and a plastic corrigated wire harness cover fixed the problem! The wire was grounding itself causing the instrument pannel and ignition issues. Might not be the same problem, but check the wiring. It took me a LONG time to find the problem.... lots of wires to look at.

Speaking of grounding, try adding a ground (or multiple grounds) from the block to the body.

Roziroz before the car stoped working when you were driving the car when you hit bumps and stuff did your car lights flicker inside the car or check the check engine lights ?? Etc
