I own an 89 Honda Accord. Today I put 2 gallons of a substance which I thought was gas in the tank but it turns out it must have been something else. Not sure what. Car drove erratically for 15 miles then was parked for 4 hrs. When I tried to start engine after sitting it would not start. I know I need to drain the tank. How do I do that and then what?

Hi scottishtim,

Under the fuel tank there is a drain plug that youcn remove to drain the fuel tank.

However it would not allow the tank to be completely drain as it is not at the lowest point.

The best option is to remove the fuel tank for a flushing.
The closest you can get to draining out without removing the fuel tank would be to use the fuel pump.

Disconnect the fuel rail hose from the fuel filter and put it into a receptacle for holding the fuel to be pumped out.
Unplug the PGM-FI main relay and use a jumper to bridge terminal # 5 and 7. Turn ignition switc ON and the fuel pump would operate to pump out whatevr is still left in fuel tank.

Add some fuel into tank and repeat process to clear any residues in tank.
Replace the fuel filter and reconnect the fuel hose.
