Hi all! Some friends and I share a 91 Nissan pickup that we use mainly for hauling stuff short distances (loads of mulch, helping people move, etc.). Recently we got the fuel pump and tank replaced after it was having some fuel line issues (not starting at all). After we got the work done, the truck ran fine for 5 miles or so, and then broke down again with exactly the same issue – it would crank but not turn over, as if it was not getting any gas. Sometimes it would start and run for a few seconds but then die out. Our mechanic said that maybe the the junkyard tank they had originally installed was dirty and there was trash clogging the fuel line, and they found a new tank and replaced it for us at no charge.
Now our truck will run great for maybe 20 or 30 miles, and then die out again with exactly the same fuel line issues. The weird thing is after it rests for a while (or maybe after it is moved/towed), it starts right up again and will continue to run for a bit, and then die. Sometimes we can even get it to start again after waiting just 10 or 20 minutes, and then sometimes it continues to crank but not turn over for a few weeks until it starts running again. Last time we got it towed to the mechanic it perked right up as soon as they got it in and worked, and I felt kinda stupid for having them tow it in the first place.
Any ideas of what could be causing this intermittent problem???
