Allright. Did a tune up yesterday and it ran the best it has in a long time. Drove around town and drove briefly this morning no problem. Fuel tank is low. Wife wants to drive today. I say no problem, but you need to get fuel. She drives 5 min to gas station fills up and drives 5 min and dies in an intersection. I'm thinking low fuel caused crap to get picked up out of tank. Fuel comes out bottom of tank. Fuel filter is back by tank. Change filter. Seems to start and idle better but cannot Rev up, at all. Gets worse, won't idle. I think is line plugged or Fuel pump bad. Get gas can and hose hook up directly to Fuel pump. No change. Figure Fuel pump is bad, change Fuel pump. No change idles sort of. I'm stumped. Thoughts??
Mine acted like this and the filter was stopped up. If fine before the gas station, maybe blow back through the lines and check filters. bad gas is a possibly? But you eliminated those Clean lines between carb and pump? Trash in the carb? A total coincidence and it’s an ignition issue? Had a weak spark that caused it to act like it was stumbling from a fuel issue.
I suspect there was a lot of water (besides the sediment) in the bottom of your tank and now it's in the fuel line. Disconnect the fuel line some place under the hood and pump out some more before trying to start it again. If not, a major purge of your lines / tank might be in order. And / or your carb bowls and jets?
I did that. Kept pulling the choke, it’d run a little better, then I’d pull the choke some more. Looked in the mirror and I had downtown Birmingham smoked up. Then it clicked in my head, I used that weird green handle pump. Luckily I had a 2 gallon gas can. Ran a hose to it and drove home Fun times
2 different carbs, 2 fuel pumps and 3 filters later...and it ended up being a worn wire on the ground side of the coil where it goes into the distributor...BUT, it sure acted like a fuel problem
So did you hook a gas can to the fuel pump and then take the fuel line off the carb to see if the pump is really bad? So far you have used the parts cannon with no fix, now it's time to start testing things to see why it won't run. If you look down the carb with the air cleaner off (engine not running) do you see the accelerator pump squirt fuel when you move the throttle? Will it start and run if you dribble a little gas down the carb throat? If it won't, do you have any spark at the coil? (be sure there isn't any spilled gas when you check)
She didn't put DEF in it? A lot of the stations that sell diesel stations also have a def pump now. Other than that I'd take a small container and fill the float bowl though the vent tube and see if the engine fired and ran at least until the float bowl ran dry. It should run for between 30 seconds and a minute that way. That will either eliminate or confirm at the engine issues. You didn't make any other changes since you drove it yesterday such as put a new gas cap on or ??? Before she drove it today?
Did you change the condenser as part of the tuneup? Wouldn't be the first time a new one failed, many of us have had that happen with the poor quality ignition parts they are making now. I know it sounds like a fuel problem but I've heard said more than once that a lot of fuel problems are really ignition problems. Possible that the strainer in the tank is clogged but that's pretty rare.
Had one act the same way. Filling the tank broke loose a huge flake of shellac from the inside of the tank that would suck up against pickup screen. Searched high and low, drove me nuts.
The car is expecting a SBC not a Ford engine. The car is rejecting the engine. You need anti rejecting drugs or a different engine.
So it ran good for a couple months and then.... lately in 5th going about 70 at 2000 rpm it stumbles like it's going to die. Put the clutch in and Rrev it up and it's fine. Clutch out stutters. Down shift to 4th no problem runs great under load. Any ideas? Ignition again? Fuel?
