No it will NOT harm your truch, providing you did a decent job at draining the tank, the fuel lines, and at least draining the fuel filters. Even if a little gasoline remains in the fuel system somehwere it will get mixed with the diesel to the point of no damage. Also, I'm not sure exactly what year model Chevy started it, but in 1992 and on Ford installed low pressure sensors in the fuel filter block so the fuel pump will simply shut down preventing damage. to diesel engines for this very reason AND for the natural condensation factor during cold temperature conditions. Hope this helps answer your question, but you'd probably feel better by taking this information and doing research on your exact model to ensure accuracy. Once you get it running let's tie up with my 7.3L powerstorke and have some fun... I'm just messing around with ya there. I AM a Ford fan, but I also appreciate Chevy and Dodge as well. Made In USA! At least they're assembled here anyway... LOL!! Good Luck, my cyber-friend.
You will destroy a diesel engine if you run gasoline in it. Do not even start the engine. You will have to drain the fuel tank, and all fuel lines.
Running gasoline in a diesel will do serious damage to the engine. You must remove all the gasoline from the tanks, & fuel lines. Purge all gasoline. If you have not starter the engine just drain the tanks.
If you filled it with more than a couple of gallons, you will need to drain the fuel tank and fill it up with unleaded fuel. It will not hurt the engine to run it with the little diesel left in the tank. You may also have the drain all the fuel lines to get it started. I would also replace the fuel filter.
If they filled the vehicle, sure.
If you mean how do you FIX it, then drain all the gasoline out of the tanks. Disconnect the fuel lines and blow out all gas from the lines. In other words remove all gasoline from every component on the truck.
DO NOT put gasoline into a Diesel Engine... EVER. Gasoline engines work on the principle of Combustion caused by compressing gasoline and oxygen and then adding a spark to cause a controlled explosion called "Combustion" Diesel engines do not use a spark to ignite the fuel. Diesel fuel will combust on its own when under pressure and heat. The Glow Plugs in your engine provide the initial heat to start the combustion process, but once the Engine is started, the glow plugs shut off and it is just a process of Heat generated by the previous "explosion" and the compression of the fuel and oxygen. If you put gasoline into a Diesel engine, it will not start, and if by chance it did, The thermal (explosive) properties of gasoline are very different from a Diesel fuel and you would probably destroy the engine. If you have put only a small amount, say a quart or so, your worries are small. Fill the tank the rest of the way with diesel and run it. A small amount of gasoline will not hurt a diesel engine. In fact, the US Army, back when the engines were diesel and not multifuel, typically had the practice of adding a quart to a gallon of gasoline to diesel truck tanks in the winter to prevent foaming. If you have filled the tank with gasoline, however, do not turn the engine over. Drain the tank and refill it with diesel.
Drain the whole thing ... the two fluids mix well. (but a few percent diesel will not hurt a gas engine.)
How in the world did you put diesel in your Accord? The nozzle will not even fit. You cannot drain it but you can pump it out. Buy an inexpensive hand pump and get the diesel out. Then fill the tank with gasoline and start the engine. You may have to also drain the fuel lines.

One or two gallons of gasoline to a tank of fuel won't hurt your diesel, but if you filled it up with gasoline you MUST get it all out. That may involve removing the fuel tank to drain it. You could just disconnect the fuel line at some convenient point, siphon everything out that you can get, then re-connect the fuel line. Drain everything out that you can get, as close as possible to the injectors, then attempt to start the engine, but recognize that there is some risk involved. You may need to use some starting fluid even though the manufacturer recommends against it. After you once get it started the remaining gasoline should work through quickly and if you don't destroy the engine in the process everything should be ok. Otherwise, take it to a diesel mechanic to have the gasoline bled out professionally.
I have a 52 plate Picasso and my slightly dimmer half put 20 pounds of petrol in my diesel car. There was about 5 - 10 pounds of diesel already in the tank. I simply syphoned the tank with a hose and a bucket. doesnt taste nice i know, then filled it with diesel and a fuel treatment and ive had no problems since. this was a year ago now. Its not usually bad this way round as truck drivers put a small amount of petrol in their tanks to stop them freezing in the winter. its when you put diesel in a petrol engine that you've got a problem.
Drain the fuel tank, and replace fuel filter.Drain the fuel tank, and replace fuel filter.
