Anyone know why my 96 blazer will not start after the fuel pump has been replaced ? The pump is running and I have pressure at he injector rail schrader valve but the engine will not fire. Is there a reset to be performed or a trick I'm missing ?

 

whats the truck do when you try an turn it over. does it click or does it just do nothing at all

 

Do a fuel leak down test. You need 60psi key on engine off and no less than 55psi after 10mins.
