Cut out on me once last fall while cruising about 35 mph for about a second then recovered. At that time I connected to the Powerlogger when I got it home and could not find anything wrong. Wiggled all connectors I could get to under the hood and it never did it again.
It was fine this year up until today. Cut out on me several times at idle and while cruising, did not think I was going to make it home. When it cuts out it is complete, like you turned the key off. No SES light, no flickering dash lights or gauges. Does not seem electrical.
While sweating bullets on the way home, one of the times while cruising about 25 mph, the RPMs started to drop instead of cutting completely out, and I had to give it a little more peddle. When this occurred I remembered to look down at the wideband and it had dropped down to between 8-9 and stayed there for about 20 seconds with the throttle in the same position. It then went back up to 14-15 where it usually is at that speed and ran normally.
When I got it in the driveway I connected to the powerlogger and let it idle for about a half an hour while I watched the fuel pressure gauge under the hood, but of course it didn’t happen again. Fuel pressure is 43lbs line off and about 38 line on and steady. I had someone look while I torqued it to about 5 lbs and rose as it should.
Does this sound like the fuel pump going bad? It is about a 9 year old Walbro 255 from Full throttle speed. About 10K miles and maybe 80 quarter mile passes.
I have attached 2 screen shots from the Powerlogger, one at idle and one at about 2000 RPM. Unfortunately, I am not logging fuel pressure.
Thanks in advance for any help.
