pathfinderfisherman Posted January 6, 2010 Share Posted January 6, 2010 it starts then runs fine for ten secs then maybe runs rough then dies like the fuel line or filter is clogged or line was pinched shut, anyone run into this?? it did die once at the gas station after i started it and popped the hood to check the trans fluid, then drove 5-6 hundred miles, got home went fishing next day ran fine parked it and here we are ecm gives 55 all clear.....was gonna clean MAF and check the IACV but wasent clear on checking it or cleaning it so any help would be greatly appreciated is there anything to do with the fuel pumps that would let it run for a few then kill the pump???

BowTied Posted January 6, 2010 Share Posted January 6, 2010 It sounds like a fuel pressure regulator, possibly. I have not had that happen, so can't say for sure. Link to comment Share on other sites More sharing options...
Kingman Posted January 7, 2010 Share Posted January 7, 2010 I would start by replacing your fuel filter if it hasn't been replaced recently. Poor wiring to the fuel pump would also cause the engine to run rough. Link to comment Share on other sites More sharing options...
unccpathfinder Posted January 7, 2010 Share Posted January 7, 2010 sounds like my 95 and I'm pretty sure its the IACV b/c i can give it gas like a carb engine and it will run and sometimes after highway speeds and clutching it'll die...I've seen this on a mustang before but much worse...so thats my guess for my truck Link to comment Share on other sites More sharing options...
nismothunder Posted January 7, 2010 Share Posted January 7, 2010 Full filter or a dying fuel pump,the pump will do this when its getting ready to let go.Goes down hill until the pump wont push any gas at all...(most times if a pump is on its last legs it will still give anuff gas to the engine to make it onto a trailer(like you stated will run for 10seconds)) Link to comment Share on other sites More sharing options...
pathfinderfisherman Posted January 7, 2010 Author Share Posted January 7, 2010 (edited) Also I should add that the fuel filter and line is clear......ill try to dig through my FSM's and see if i can come up with all the voltage and ohmage readings and take one of the most handy tools that my pathy gets all the time ......drumroll......the fluke 87 multimeter!!! lol at least pathys have one of the most owner freindly engineered vehicles ever made between the box under the seat and the FSM ....the best vehicle i have ever owned hands down ....she refuses to strand me my wife went home over the holidays and had her dodge strand her in the middle of the interstate xmas eve, hence the 5-6 hundred mile rescue journey to go get her and the kids my wife never told "her"( my pathy) even thanks....i went fishing no prob hit some brownies through the ice , came home and the wife moved it next day to put our other dependable car in the pathy's rightful place .....it's a mazda...sorta ..( her dodge threw timing bent valves so I sent it where it belongs ...the junkyard) and hasent run since for more than a few secs...I just think if she would quit talking about the dodge(rip lol) and pet up the ol pathy a little more like me this wouldent happen (an apologie would probably work best) .....the pathy hasent liked her since i let her drive on vacation and she hit a dip hard fully loaded... or maybe they could be jealous of one another wanting my affections .....i could say the solution would probably not ever let her ride in it again.....in case she reads this all i will say is i will always have my path she loves ME lmao.... we romp and fish climb and mud....nothing stands in our way...not knock sensors, or alternators or starters actually those are the only real probs i ever had that might have come close to stranding us except ...oooh yeah i tuned her up right when i bought her.... I cleaned up the dist cap and loosened the screw on the rotor and must not have tighened it back, well goin down the road well a major hill anyway she smacked and then sputtered to the bottom and i shut her down ....she only sputtered cause the screw was jumpin round in side the cap shortin out lol, it broke the back off the plastic rotor...horrified i removed the plastic and put her back together....she drove me home and held in till i got new stuff.... i only put all this in cause i hope there is a lesson to be learned my love affair with my pathy will last forever........ never let anyone unfriendly drive or even sit in her she is the one u can trust... with my assortment of scavenged relays new belts, hoses a multimeter and tool box and bag we are unstoppable she is a truly dependable truck the likes of which i don't believe has been seen before or since and used to be a old school full size driver thats to all my friends here jus in case u haven't been showing yer special one the love( imean your pathy's not your wives lol but kiss the wife jus the same) and we thank u guys for all the help and for being there when some fixin needs done thats how much i love her i came in for advice and had to tell the world just how i feel ..............so should we all.... ALL HAIL THE PATHY'S MAY THEY BE WITH US FOREVER!!!!! so can i still test to make sure its getting current to the pump after it dies?? even though it wont be running? or could some relay or sensor be not working right and it quits telling the pump to continue pumping????? ok so im headed back to the fsm for some numbers for testing the pump if i can find them i thought there was a relay near my wiper fluid box??

Kittamaru Posted January 7, 2010 Share Posted January 7, 2010 heh, I know what you mean about bein in love with the truck - mine is giving me intermittent starting issues that I cannot for the life of me figure out... the extreme wind and chilly weather isn't helping as I don't have a garage of any sort to work in, much less a heated one. My mechanic is going to replace the starter monday and we hope to god that's it... but I'm already broke due to other RL issues and yeah... I dont' want her to die on me, but I can't afford life support 0o' Link to comment Share on other sites More sharing options...
Kingman Posted January 7, 2010 Share Posted January 7, 2010 Make sure you keep up on the timing belt/water pump maintenance or your Pathy will have the same fate as the Dodge. Link to comment Share on other sites More sharing options...

87pathy Posted January 10, 2010 Share Posted January 10, 2010 not sure on the pathy's BUT this is exactly what happens when the MAF on a toyota goes bad. and you can't properly check them. if you test it and its all over the place, its probably OK if it give you a steady resistance reading, its most likely no good.

pathfinderfisherman Posted January 11, 2010 Author Share Posted January 11, 2010 well beep beeepy beep 30 secs it ran today and then it acted like it was missing for a few seconds then died im gonna take the hatch off in the back im guessing thats where the problem is gonna be i jus ordered the new sending assy interesting sidenote/backstory about 2 years ago this happened too...my wife got in it maybe drove it to work even...parked it next to the maple tree i went ou to get in it andit just cranked over.....i tested all the same things minus the vacuum press reg, and tested it to the back harness that the sending unit goes to. thats when somebody told me about tht hatch(I LOVE tht hatch) i popped the hatch and the power wire was pulled away from the pump ...now we all know there aint enough tension in jus that one wire....maybe something running for its life jumped up in tween the tank and the body but i couldent get my hand there...without the hatch.....it was corroded and i cleaned and soldered it back heavily..im betting its another wire or a 17 yr old pump, possibly the same wire loosened with ice freezing under the solder, we'll hope for just that. oh yeah once again she parked it there......lol....no probs since but its always in the back of my mind i might get to use my new fancy batt power solder gun out in the wilds and get another tesstament for my pathy gonna test the old one now and see if i can fix it again till i get this new one thanks fer so far Link to comment Share on other sites More sharing options...

My truck loves me....i think it's tryin to blame all this on the wife.... my wife is like a black cat to any vehicle she has lol she's car unfriendly or accident prone whatever maybe if i let my wife watch that stephen king movie about the car she wont even want to drive it anymore..after being framed both times it looks kinda bad lol Trout through the ice tomorrow, yay Link to comment Share on other sites More sharing options...
