Plowing snow and hit a bank hard and engine quit. It is a 1991 D-250 with the 318 engine. I suspect there is an inertia switch in the fuel system that tripped buty, I can not find one. Is there one on this truck? Also wanted to put a fuel pressure gage on the fuel line and I do not see a schraeder valve to do this. Any help would be really appreciated!
Thanks

 

i dont think there is a InertiaSwitch on these things. have you check for spark? you could try pouring a bit of gas down the throtle body and if it start it is a fuel problem. if it doesn't it could be an electrical.

 

With a TBI system you must tee into the fuel supply line to check the fuel pressure. There is no inertia switch on our trucks.
