catfish1987 Posted March 2, 2009 Share Posted March 2, 2009 Ok so this weekend I went to meet some friends a couple hrs. away and my pathy ran good all the way there and while we were running around the city. Then for no apparent reason it died. It started right back up and was ok for a bit and then died again in a parking lot. We sat for a minute and it started. I parked it went and ate and when we came back it started fine and drove for about an hour before it died again a couple times in just a few miles. Again sat for a few minutes and it started and drove the other hour home. It ran fine except it would kinda stall out around 3000 rpm acted like it was not getting gas. So I changed the fuel filter, pump, and pump relay. Also have changed the plugs, wires and the rotter cap with in the last 6 months. Now it will start and run for a bit and then when you try to drive it dies. After it sites for a bit it will start and run but dies every time i try to drive it. I need to get this fixed asap as it is my only car. am think maybe the coil and may try to replace it tomorrow. Any help or suggestions would be greatly appreciated. FYI it is an 89 V6 4x4 FI other info in my profile. Link to comment Share on other sites More sharing options...
Kingman Posted March 2, 2009 Share Posted March 2, 2009 (edited) A coil only works, or it doesn't. Don't waste your money on that. The wiring to your MAF sensor could be finnicky, or the sensor its self could be dirty. There's a how-to on cleaning it. Check the power wire to your distributor and make sure that's tight and sealed. That's all I can think of...

beastpath Posted March 2, 2009 Share Posted March 2, 2009 alternator issues? Link to comment Share on other sites More sharing options...
catfish1987 Posted March 2, 2009 Author Share Posted March 2, 2009 I have been told by two different people that the coil could be cracked or something and could stop working when it gets worm. It has a new alternator, again about 6 months ago. Link to comment Share on other sites More sharing options...
Kingman Posted March 2, 2009 Share Posted March 2, 2009 (edited) Have you ran the diagnostic on the ECU yet? Edited March 2, 2009 by Kingman Link to comment Share on other sites More sharing options...
MY1PATH Posted March 2, 2009 Share Posted March 2, 2009 mine had similar issues; stalling out exactly @ 2800. It took a while to figure out but it was the injectors. their resistance had gotten so high that the ecu went into limp mode. this can also happen if the resitance gets too low and it can also permantly damage your ecu to where it will make the next set of injecors fail. whatever it is I hope you get it fixed soon.

catfish1987 Posted March 2, 2009 Author Share Posted March 2, 2009 Havent been able to get it to a shop but may try in the morning. Thanks for all the help so far. Link to comment Share on other sites More sharing options...
88pathoffroad Posted March 2, 2009 Share Posted March 2, 2009 Definitely run the ECU error codes. Do the basics first. When it doesn't run, does it lack fuel or spark? Link to comment Share on other sites More sharing options...
catfish1987 Posted March 2, 2009 Author Share Posted March 2, 2009 Changed the MAF sensor and it ran for a bit and then died when I was trying to get it to a shop to run diagnostics. My dad and I messed with it a bit and got it to run again and he thinks it is the plug wires so I ordered the best set I could fined this time (since this is bout the third set I have put on it). They are going to be in in the morning. Will see what hapens from there and will let yall know. Link to comment Share on other sites More sharing options...
88pathoffroad Posted March 3, 2009 Share Posted March 3, 2009 Throwing parts at a mystery problem is likely to get expensive fast... Link to comment Share on other sites More sharing options...
Kingman Posted March 3, 2009 Share Posted March 3, 2009 How many times does this need to be covered? You DO NOT need to take it in to read the codes. There is a how-to on this under self diagnostic I think. Taking it in to someone is a 100% waste of time, gas, and money. Link to comment Share on other sites More sharing options...
Kingman Posted March 3, 2009 Share Posted March 3, 2009 Here's that how-to. http://www.nissanpathfinders.net/forum/index.php?showtopic=21 Link to comment Share on other sites More sharing options...
88pathoffroad Posted March 3, 2009 Share Posted March 3, 2009 Yeah, Pathfinders didn't get OBDII until 96. There's nothing to plug a code scanner in to on an 89. Link to comment Share on other sites More sharing options...
catfish1987 Posted March 4, 2009 Author Share Posted March 4, 2009 Hey thanks for the info. I did not know about the self diagnostics. Will try that in the morning. Link to comment Share on other sites More sharing options...
catfish1987 Posted March 4, 2009 Author Share Posted March 4, 2009 Ok so its the TPS. where and how? Link to comment Share on other sites More sharing options...
Simon Posted March 4, 2009 Share Posted March 4, 2009 On the throttle body, I believe. Unscrew and unclip the electrical connector.....install is reverse of removal. Link to comment Share on other sites More sharing options...
catfish1987 Posted March 6, 2009 Author Share Posted March 6, 2009 Well I changed the TPS and it ran good all day then died about 10 min. ago on my way home. Dont know what else to do. Is there any thing that could be making it malfunction or something? Im at a loss of what to do. Link to comment Share on other sites More sharing options...
Kingman Posted March 6, 2009 Share Posted March 6, 2009 Check the wiring to it. Chances are, if it ran great till suddenly there's a faulty connection somewhere. Run the codes again as well. Link to comment Share on other sites More sharing options...
catfish1987 Posted March 7, 2009 Author Share Posted March 7, 2009 Died again today and wont start at all. Ran the codes and it says the same thing. Link to comment Share on other sites More sharing options...
