I was out wheelin and my rear bumper took a prety hard hit comming off a rock; directly after that my car was dead. when i go to turn it back on every thing works fine, the fule pump is wining like it should and the car is cranking over strong, but no gas, no go. latley i have noticed that my gas gaudge is not reading properly, i believe that this could be the fule sending unit doing this and that nasty hit i took could have killd my sending unit, i am not sure just a hunch. any type of info would be more than appreatiated. thankx. O ya this is an 87 k5 so it is F.I. the throtle body is not getting any fule when i try to crank the engine over.
