The fuel pump went out, so i changed that. the new pump is working and i am getting fuel up to the throttle body, but no fuel is spraying from the injectors. tried putting fuel into the carburetor but it still wouldn't fire. pulled one of the plug wires and did the screwdriver test. i am not getting any spark either. are these two issues related. how can i fix them?thank you

Hello,

it sounds like you need a rebuilt distributor with new ignition module and pick up, if there is no spark the computer wont turn the fuel pump on. Here is how to change it out. Check out the diagrams (below). Please let us know what happens.
