I just put new fenders and hood on it. I started it up it was running good then couple days ago I started it up because it was getting cold out it was running the I smelt Electrical burning I shut it off then went out the next day try to start it I have no fuel pump or spark what will cause it? I checked the fuses and relay they are good.

 

Usually when doing body work, grounds are a problem. I am going to assume yours is fuel injected. If your large ground has a problem, sometimes the starter tries to use one of the smaller grounds. I believe the fuel injected trucks have a smaller ground coming off the ground cable at the battery and going around behind and bolted to the metal fender and or going on to the computer for it's ground.

Look around the battery really good, you might have to pull it out, and see if you have a melted ground wire in that area. If you do repair it, and then check your large ground from the battery to the engine block and make sure it's good and hooked up.

 

There is a small ground to the fender I hooked it up. Ill look at the other grounds see how they look but thanks
