  1. I am starting to agree that it is either the ecm itself or the 02 sensor, right before it started doing this it snowed about a foot and I had the pathy filled with people and dogs driving around in deep snow every day for a week. Timing was spot on when I did a tune-up right before all this started thank you Alkorahil for your continued help.
  2. I plugged an injector test light into the number 1 injector and caught a time when it went from no start condition to start and have determined when it won't start it is because it is not getting an injector pulse. It still reads 55 in mode 3 when it does start
  3. I am contemplating this engine swap; td 2.7 5 speed into a 92 auto pathy, I have the clutch pedal setup out of a 92 d 21 is there anything to look out for how about wiring issues? I assume the td 2.7 is mechanical diesel and just needs hot fuel solenoid to run. Any and all info would be appreciated.
  4. Filters good I was going to change the FPR, in fact the whole injector rail, with a known good spare that I have and maybe the whole air collector assembly if needed
  5. Adamzan, thanks, maybe both pumps are bad? I have all ready changed it with my parts car pump, reads 43 psi til the relay kicks out, when it starts it will idle at 32psi these numbers are gotten with vacuum unhooked from FPR because that's how it was when I got it and intake will have to be split to put vacuum hose back on, when I do that I will replace FPR. I live in extreme North Arkansas it's 18 degrees right now headed towards a low of 2 tonight so intake splitting will have to wait a few days. My garage is full of my other D21/wd21 parts so I have to do it all in the driveway.
  6. Thanks for the info, I did change the yellow 2 prong no help. The frustrating part about this issue is there have been no symptoms it was running great. When I can get it to start still runs good until it gets shut down.
  7. 92 Pathfinder still wont start I am starting to feel like this issue is definitely temperature related, engine will only start when outside temperature is low. I have changed temp sensor with a used but functioning one and cleaned all under hood harness connections with contact cleaner and coated connections with dielectric grease still hoping for o2 sensor problem won't be able to get new one until later this week I think that cold air being richer in oxygen is allowing it to start somehow
  8. Thank you Rob for the good troubleshooting info. I tried unplugging the IACV and then the throttle position switch, I also switched MAF and Coil out still no start. I am with you on thinking it may be temperature sensor. Tomorrow it is supposed to get above freezing and I will change the temp sensor in the thermostat housing with one from my parts car but I am totally willing to try anything that will get my pathy running.
  9. Thanks for the replies It's an auto trans and the starter always cranks. I will try and swap those driver side relays around see if that doesn't help, it doesn't seem to matter what position the throttle is in when it doesn't start. When it is in "no start mode" it will fire on starting fluid but dies as soon as it burns up the starting fluid. Next morning it will start right up and run good until it's shut off again. I have a spare injector rail with a fuel pressure regulator on it if nothing else works I am going to run fuel to it and plug it into the passenger side injector harness and see if the injectors are working. Going to have to warm up a little for that it's supposed to be 5 degrees tonight here my 22 year old wiring harness will be less brittle when it's warmer.
  10. I have a 1992 pathy and it will not start when the engine is warm or any time after it has run for a few minutes. I am getting spark and have replaced plugs, distributor cap, and rotor. I have a pressure gauge t'ed into the fuel supply line and am getting 40 psi with key on engine off and 33 psi with the engine idling I have put ecm in mode 3 and am getting code 55. first thing in the morning it starts just fine probably turns 1 or 2 revolutions and its running and idling smooth if you turn the engine off it will not start unless it sits for a couple of hours. I am an experienced mechanic but this thing has me stumped for now, any help would be appreciated. I have a 1995 parts car parked next to it so swapping parts is easy I also have the 1995 fsm and have been following troubleshooting procedures but cannot find anything wrong
