Parent Category: Fuel and Engines
Fuel is a requirement for all internal-combustion engines. Fuel is stored inside a tank. A fuel pump then siphons the fuel into the fuel intake which is connected to either a carburetor or a fuel injection system.
The fuel pump is located inside of the gas tank. Best way is to run most of the fuel out, then you have to lower the tank to get to the access plate on the top of the tank. raise the suv and block the tires, be sure engine off and keys out, remove the tank straps holding the tank in place, put a ja…

The crank sensor would definitely cause no spark. As for the no power to the injector it might actually be the ignition controll module(as odd as it may seem).

In most cases I have to ask if your engine has a mechanical fuel pump. If it does then more than likely the diaphragm of the fuel pump has failed and is letting the fuel come in from the point that it is at. If it does not have a mechanical then you have a real serious problem with the fuel delivery…

You can probably change the sensor yourself. But you have to know which one is bad. You will also need to buy an O2 sensor wrench. It's very difficult to get out without the proper wrench.

You can spray (with carb spray or special fuel injector linkage spray) the linkage around the throttle body, but the injectors, which are really the main part of the system are always being cleaned with gas while you drive.

No engine damage. The problem is that the spark plugs won't ignite the diesel fuel. If you can drain all of the fuel lines, most of the tank and fill back up with gas and clean or replace plugs, then it will probably start right up. Back in the 50's, some gasoline tractor engines would start on …
