So I have a 1997 Nissan Pathfinder 4WD Automatic V6 with 184,000 miles and no codes or check light.
A few days ago I was underneath the vehicle cleaning up the bottom in preparation for an undercoat with rust bullet. I noticed some gasoline leaking from the metal fuel line after the fuel filter. It was rusty and developed a pinhole as the protective coating came off the line on that piece.
So I cut off the line on a clean section (about 3 inches) and put a longer fuel hose coming from the fuel filter to that line.
Since then I’ve been having an occasional random crank but no start condition. It will crank over several times and I would have to release the key and try again before it would start. This occurred this morning after sitting over night, occurred today after sitting for 20 minutes, occurred after sitting for a few hours. It’s very random.
Debris didn’t get in the line as I cut from a clean section that was covered with the rubber sleeve. And after I cut the line, fuel was running out the line which would have pushed anything out if it even got in. There’s no leaks anywhere else.
I hear the pump prime when the ignition is on. There is no rough idle or issues driving. I can floor it on the highway and it responds perfectly fine.
I don’t see how putting a new hose on that’s maybe 3 inches longer to compensate the shorter metal line would cause this.
What could it be?
I would double check you still don’t have a leak.. most metal lines has a rib on it where the rubber hose connects to seal the hose. If you cut the line you won’t have that rib and it could leak from there
I did, there was nothing leaking. I had the vehicle running for about 10 minutes and then drove it around the block several times after doing the repair. Dry as chip, no gas smell either.
Could it be fuel pump?
I wouldn’t think so since it only started after the line repair.. did you change the fuel filter when you did it by chance cause I know those filters are directional
