@#$%#$#!!!!!! Starting issues!!

[NissanPride247]

My 89 240 just won't start!! I've had it on the road for a few days now, I drove it to school, parked it, it sat for 2 hours then I went to drive it to auto shop and it wouldn't start. It turned over and over and over but it wouldn't fire. The battery is fine, it turns over fine, it just won't start. What could be the issue? Fuel pump is ok the wires are giving a spark. Someone help please!!! I have been working on this alllll day!!!! Detention for sure. I'm ARGH!!!!!! Thank you

Is it making any strange sounds, anything unusual, i need a little more info. Check the fuses and relays in the starting system, under the hood and dash, that would be my first stop. Is it a manual?, get a friend and try to pop the clutch. If that works i iwould stay in the starting systems electronics. Are all the injectors firing. Are you sure the fuel pump works? Did you try starting fluid or gas. I would soak the air filter in gas and then try to start it. If it starts it is the fuel pump or a clogged fuel filter.Try some of this, If it works were cool, if not try and give a little more info.

[NissanPride247]

I checked all the fuses and they are good. I pulled a main fuel line after the filter and had a friend crank the engine over and it was still pumping. And I'll give the starting fluid/gas on air filter trick. It doesn't sound strange when it turns over but I will try to explain better. Thank you and I'll be back asap.

Did it start??

[NissanPride247]

Ok so it starts after it sits for a while and if I let it idle it dies after like thirty seconds!! Like I'm so lost. What could that be now? I want to think it's just bad plugs and wires but it seems more than that.

[ghettoslide]

Check the gap on the plugs and your timing, Loosen the screw on the distributer and turn it a bit, also check the contact in the distributer

[NissanPride247]

Ok so I ran a diagnostics computer on it (which I did before) and I checked codes and came up with a code 12. Which it said was Mass Airflow Sensor. After cleaning all connections it starts and doesn't die. But I have a huge loss of power and the motor is shaky when idling. So what? Should I grab a new or used MAS or do I try to find another probelm?

[janda240sx]

You prob. need a new MAFS. I would also replace the distributor and cap. and the plugs and wires. I might have a good Mafs laying around somewhre if you need it.

[NissanPride247]

Yeah that's what I was thinkin. Let me know if you have one. I will definently buy. A regular tune up is definently in order.

[srpowered240sx]

swap maf sensors with chris. you will know right away if your car starts running fine.

[NissanPride247]

Ok so I swapped them and it still stalled and had trouble starting. Then after it stalled I tried again and it wouldn't start. So what could it be now?

[srpowered240sx]

well then you pretty much ruled that your maf is good. check for vacum leaks (that car had been sitting for a looooong time, so hoses get cracks and holes in them), fuel injector seals is another thing i would look into. also check the maf wiring harness, may have some bad pins in the connector.

My 89 was having this problem, and it turned out to be a bad connection to the sensor on the top of the motor in front of the fuel injectors. I got a new connector from the Nissan dealership, replace it via solder and it worked fine. However mine would run, but a huge loss of power. One other thing to look at would be a good ground from the motor to the frame. Also one of the plugs for the injectors may be making a bad connection, just wiggle each one and see if it runs any better. You may want to try changing the fuel pump. And also try checking voltage getting to it via a voltmeter and make sure the voltage doesn't drop after 30 seconds.

Have you checked you fuel filter, i was having a problem similar to this

[richcoosa19]

Good point there may be junk in it if you ever have ran it low on fuel both in the filter and the mesh filter at the end of the fuel pump pickup.

[NissanPride247]

Ok so I have plenty to look for. How do I check the harness for problems? Just wiggle the connection? I will keep you all updated asap. Thanks!

If you are referring to the injectors, I unplug each injector one at a time to see if I can tell a difference (rougher or no change). If there appears there is no change, more then likely that plug is making a bad connection. Also try jiggling each injector's plug and see if that smooths it out a bit. My problem ended up being a bad termination at the cap from the wire. A new cap will fix that and fit snuggly. Now that I think of it, I also got a new Throttle Position Sensor as part of my troubleshooting.

[NissanPride247]

I did the wiggle test and the connector furthest from the front was making a bad connection. So I'ma take the car out today if everything looks fine and see if everything is as it should be. So cross your fingers for me!

[richcoosa19]

Definately man...let us know the outcome either way.

[NissanPride247]

Ok so my second from the front injector leaks. HELLA BAD!!!! Like I have five dollars worth of fuel sitting on the autoshop floor! I checked the o ring and it was torn. Not sure when this happened but whatever. So I buy a new pack of those expensive bastards and try again. And it's still leaking! it's pretty bad. Both o rings are good but it still leaks. Tomorrow I'm going to check the fuel rail for little bits of rubber possibly still in there. And I'ma swap places with the leaking injector and one that doesn't and see what happens. Any other suggestions?

[richcoosa19]

If you look here:http://www.courtesyparts.com/b....html

16603F and 16603G

you can see that there is an insulator both on the top and on the bottom of the injectors plus the o-ring(16412F). My top insulators were leaking along with the o-rings when I had the problem.

[srpowered240sx]

yeah, the injector seals are a common thing. just make sure you are replacing like for like (exactly the same size shape oring); and lube it up good before reinstalling. always make sure the hole that youre sticking it in is free of debri/burrs/random chunks of stuff.....this is automotive advice, and sex advice, heed it well.

[NissanPride247]

Cool I didn't know there was a second insulator. I will deffinently check that. And I will heed the advice well. lol. Thanks guys this will be updated asap

[NissanPride247]

Ok so NOBODY in this gay town has the right o ring. Both auto shops and te hardware store don't have it. Both auto places gave me what was supposed to be the right size but it was off by a good bit. So I don't know what to do. I'm thinking either I have after market injectors or that the auto places here are gay (highly likely) I'm going to call a dealership tomorrow to see whats up. Any other ideas? I'm pulling my hair out!!!!

[aquariustiger]

hey try this place ; but call them direct & ull usually save a couple of buck extra; I sure did!

U definitely need O.E.M.

[richcoosa19]

If you can wait for shipping, you can order from the website I showed you. Just click on the part number for each part and it will be added the the shopping cart. These guys are really good, I have ordered several parts from them. Once again, the link is here: http://www.courtesyparts.com/b....htmlThis is from a dealership in Richardson, TX and as such they are OEM and have pretty much everything you might need for your car (as SHOULD your local dealership). I gave the link so you could have the part numbers and diagram when you called your local dealership, they usually don't keep parts like these in stock so they they will most likely have to be ordered. These are dealer items and part stores will try to sell you generic parts that are not specific to your car (probably why they didn't fit).

[NissanPride247]

Ok I will chekc that out. I also found four new injectors with all gromets and o rings for 40 plus shipping of 10 on Ebay motors. Now I am not comfortable with Ebay with stuff like this but the guy has sold over a hundred of these kits with no bad returns so that may be the way I go. I was in Reno yesterday and was going to go to a dealership but I had to get home asap. But I will let you all know when I make a decision. The car is at autoshop for the week so I can't work on it. Thanks for the help!

[NissanPride247]

Ok so I called Nissan of Reno and they have 2 O rings left so I am getting those tomorrow And we will see on monday.
