Will not start i have changed fuel pump geting gas to the intake manifold but it want start unless i poor gas straight into the intake

Check for injector pulse by using a noid light - IF no injector pulse (light not flashing) - - Replace the DISTRIBUTOR assembly - even thought it produces spark - It’s also supposed to pulse the fuel injectors.. IF check engine light on - codes can be gathered by OBD 1 connector bypass jumper. IF you do not understand these suggestions - seek *hands-on* assistance from qualifying personnel. Good luck!
