Yukon....Good call on the metal filings.

IF IT WERE MY CALL.....I WOULD GET THAT PUMP TO A QUALIFIED SHOP and have it looked at.

Where all the crap came from..... ?????
May be the IP ate itself....Possible lift pump failure......If there is crud in the filter you need to figure out where it came from.

The IP is constantly sending fuel back to the tank....So the entire system can be fouled.

With metal in the IP....THE STUFF LIKELY traveled to the injectors too.....

I WOULD NOT even try a restart....Find out where the junk came from...Clean up the mess...Flush the system and get the IP and the squirts in order....Then move on...



Check the filter and see if there is junk in there....
