fixed! (i'm pretty sure) i checked the vacuum lines, looked o.k.- i cut the ends off of a couple & re-attached them to get a snugger fit. cap & rotor changed last summer, plugs look pretty good. I took out the MAF per your instructions, & it looked o.k., but i cleaned it anyhow w/some electrical connection cleaner i had. what a difference! she starts right up, i drove around about 30 min. with only a second or two of sputtering (it was running like cr*p before, when i could start it) i can't believe cleaning the MAF made such a difference. thanks guys, & now, on to my water pump..

hi all, i have an '88 pathfinder- the past two days the truck acts as if it is flooded, although i smell no excess fuel. it sputters, may start after a minute or two, may not start at all. I checked for codes twice, and keep getting the '55' code (no malfunction) i also believe i have a leaky waterpump, which i was going to fix this weekend, but i don't think that has anything to do with this. it also chugs, & occasionally backfires if i do get it to run. any advice is appreciated, thanks

o.k., i conceded & had the truck towed to a foreign auto garage. The problem was a bad ground connection on a wiring harness, near the passenger side kickpanel (the man who worked on my car spoke very broken english, i did want to press for what the problem was) & this still doesn't explain the temp sensor code, but the truck does run now ($200, plus $50 for the tow ) on a side note, it seems to have lost a lot of power, not that it was a ferrari before, & I hear on occasional backfire. I guess I should just be grateful the truck runs? thanks you all for the input regardless, & I hope this post may help someone down the line --marty

the sensor, is that the one located near the front of the throttle body?

apparently i was reading the codes wrong- red lights are 10, & green are one. so, if i get one red blink, & 3 green ones, i get a 13--temperature sensor malfunction? why would this prevent my truck from starting? the truck will backfire (flame out throught the throttle body!) is it possible for the belt to 'jump'? once again, thaks for any input

o.k., went to the junkyard & found a pathfinder with a vg30 engine like mine, i could not tell what year, but it was a first. gen. this ECU has a '53' stamped on top, mine has a '10'. connections look dry, so i try to start the truck, & nothing. I try to check codes on this junkyard ECU<, & it doesn't light up at all, it is just totally dead? I put my old one back in, & the same codes-- 3 green flashes, a long puse, & then 1 red flash. So my question is, did i just happen to pick a dead ECU? do the numbers (53 vs. 10) mean anything? also, this truck was an automatic, mine is a stick-- does that matter? sorry for the rambling, but my frustration is rising. thanks again for any input

would this mean the ECM needs replacing?

hey guys, after washing my "88 pathfinder, i washed under the hood just a bit-- truck ran for about 30 seconds, then sputtered & died on the side of the road. after towing to my brothers, I see there is spark going to the plug. I checked codes, & got 3 green blinks, then a long pause, and a red blink-- this is 31, which is Ecm? so, where is the Ecm, & what do i do with it, replace it? thanks for any help, I want my truck back!

got one @ the bone yard for $14.99 yesterday, & the truck started right up. thanks trailboss!

i'll hit the junk yard this weekend. thanks guys!

hi all, & thanks for the great board. i read how to look up codes, got an 11 (ignition signal) and 21 (crank angle sensor/camshaft position sensor) where are these sensors located? & i'm assuming, i replace the sensor? thanks for the help
