my oil pressure sending switch was leaking so i went and bought a new one now my fuel pump wont turn on unless i jump the switch wire...i bought a new fuel pump relay also and it didnt help...also my car wouldnt start by its self before that and i think its something called a fuel pump primer where is that located and will that cause any of these problems any help will be greatly appreciated

 

pump primes through the relay, so if the relay is good, then the pump should prime. Have you checked the fuse by the battery tucked up in the fenderwell? Sounds like the "new" oil pressure sending unit is bad - I'd take it back.

 

yea i checked the fuse already it was bad so i changed it and it still isnt working....im just jumping the fuel pump now.....but im trying to start it again and now i have no spark what so ever the coil is gettin power to it and sending it out i doon knnow where its sending it tho... im thinking its my ignition control module or the coil thats not letting me get spark
