i don't what wrong with my ls Acura we replace the distributor ,map senor , throttler position senor,and we still get no spark to the engine and the we can hear the fuel pump anyone got any idea

 

main relay ?

 

the main relay is still good

 

Have you checked to see there's no spark? And that the fuel is getting into the cylinders?
Check engine light throwing codes?

 

Check your grounds check your wiring is correct

 

Ground is my guess

 

check for 12v at the blk/ylw wire coming off the distributor.if you have 12v,youre looking at dizzy internals or anything from the dizzy to the plugs.
if no 12v,youre looking at main relay,ignition switch,or in rare cases the ecu or wiring problems..
