My Pathfinder will not restart after it has been running and shut off. I have…
A month ago I drained the oil/removed the filter to pull a defective starter. I fixed that and a couple of days ago replaced the old oil, put on the old filter, and started it up. No problem with the oil system as I worked on a Poor Performance issue, which still remains. BUT, as I was troubleshooting the ignition system, I noticed the Oil light was on. I immediately s/d the engine and checked level: OK. Then I drained it; nothing significant was in the oil. But there was some light debris, like particles of wings, from bugs in it.
I pulled the filter: no noticeable debris in it or in the port on the Block.
I pulled the oil light sender.
I’m thinking I have a clogged system, so I blow air thru the filter and oil light sender ports, dump some gas into the oil fill port, letting it drain thru the still-open sump drain. Then I over-fill it with diesel fuel, spin the engine a bit (with the ign disabled), and get fuel squirting out the open filter port. Drain diesel fuel.
Now I’m thinking that whatever it was is flushed out, but I didn’t get anything significant out via either the gasoline or the diesel fuel.
Fill it back up with fresh oil (this time) and a new filter (this time), put just the connection tube from a stand-alone pressure gauge into the sender port, and start it: no oil coming out the sender port after about 45 seconds of running at fast idle. S/D.
Remove tube, blow air into the port.
Start again: no oil coming out of the open port after 20 seconds. S/D.
NOTE: I hear no noticeable change in engine noise thru all of this.
Pull filter: dry inside. No oil ever reached it since it and the new oil was installed.
I had the sump about 1/2 QT high, so I drained about a quart (in case it was air-bound due to the frothing) and just spun the engine a few times: no oil coming out of open ports.
SO, MY QUESTION: What is your opinion on my situation with the engine? And what do you suggest I do?
