1986 Ford Bronco II sputters and then dies it seems if gas tank

Car has sat for 3 years. Will start and run fine, then all of a sudden, it will sputter and die. It seems like when it hits a bump or you fill it above half tank of gas...it runs better for about a month, then will sputter and die again. Could there be something in the gas tank that is getting in the fuel filter occasionally to make it die? The gas was siphoned out when we started driving it and then put half tank of gas, then a couple of days later it started the sputtering thing... HELP!!

I agree with nuttbysteve. Your tank probably has a lot of silt and the screen over the pump inlet tube is also restricted. When the tank gets low, it will choke on the trash in the tank. There is also a reservoir between the tank and the front, frame mounted fuel pump. The fuel lines can be unclipped and removed from the canister and the top can be unscrewed so the reservoir can be cleaned, caution, this is an obsolete part and I have not found anyone who can tell me where to get a replacement. If you opt to clean this, you may have a leak due to the gasket inside. After searching, I did locate a gasket to properly seal this. If you change the tank, change the filter again at the same time and you should be ready to ride. Check for leaks several times after you do this, you cannot be too careful.

The engine sputters and dies when it heats up. Is this Vapor lock? On cold start it works great and idles just fine but as it heats, the engine starts choking and soon dies out. If this is vapor lock, how...


sounds like the reason it starts and idles fine at start up is your choke is functioning... as your vehicle warms up.. the choke starts to kick off... Inspect your throttle body and idle control motor.

I have an 89 ford bronco 2 with a 2.9 liter it sat around for 2 years without being started. I replaced the plugs, rotor, cap, ran fuel injector cleaner through it several times, checked cylider...


check the spark plug wires are attached all the way till it snaps, pull each spark plugs, any black deposits on any plug means it isn't firing(faulty plug,or wire) last of all take off each injector wire and notice if there is a change in idle speed (plugged injector)

Will not start without starting fluid


Try Running a Couple of Cans of B12 Chemtool through a Full tank of Gas one Can at a Time. I use this in ALL my Vehicles at every other Fill up and it keeps the Valves and Fuel System Clean all Year long. You can get this at your Auto Parts Store or Wal-Mart in Automotive. It will Clean up the Valves and Plugs and should Eat away that Carbon Build up. Could even Help with the Starting Problem also. Please Rate My Response! Thanks!

I had a geo metro that sat a long time and the gas turned to varnish. You will need to drop the tank, clean out the gunk, put in a new fuel pump and and filter and flush the fuel lines out to the injectors.
