Well, it’s been awhile since I updated the thread or even messed with the car.

A couple weeks ago With a quarter tank of gas and winter bearing down on us Minnesotans, I thought I should fill the tank, so off I went on a Saturday morning 1.7 miles to the gas station- got a few blocks away and the car stumbled on acceleration from idle. Luckily there are several large parking lots between my house and the station, so I turn into the ice arena lot and start looking at my computer and see that car is going super lean- 19+AFR, so I started adding fuel to the cells and driving around the lot, adding more and more fuel until the AFRs get decent.

I drive out of the lot and more stumbling and going lean; pull into the County nursing home lot (nursed the car into the nursing home lot!) still going lean, so more fuel it gets and I turn towards home still having lean stumbles, now I’m at a church lot doing some more fuel adds; finally I get home and I’ve had to almost triple most of the cells that before then where giving the right amount of fuel.

I looked at my fuel pressure regulator and it was at 37psi, it was at 40 originally, so I adjusted it back up- nut was tight, so likely hadn’t moved mechanically from vibration. I was able to return it to 40.

Fast forward to this morning and I decide I need to try and drive it again. I had reset the fuel tables to before the getting gas run and car started and after getting it slightly warmed up, it idled on its own and I drove up and down the driveway a few times without issue, so decided to go around the block- nope it started stumbling and I had to start tripling fuel to get it into the garage. Pressure was still at 40 psi and operating the throttle linkage, the pressure didn’t move. I’m suspecting a bad fuel pump- not enough volume? I had not changed anything else before the problem occurred.

Had a ten percent off coupon here on Pelican and a fuel pump has been ordered and with a quarter tank, less fuel to worry about.

The fuel pump has been replaced during my ownership, but have no clue when I did it and I have had this car for 32 years. I don’t feel bad about guessing on the pump being the problem.
