hi i own a 93 prelude si and the car out of the blue decided not to start. the check engine light comes on and the main relay clicks on and off very fast. i replaced the relay with no such luck. the car turns over but wont start...i believe its not getting any fuel because i can't hear the fuel pump coming on but it is getting power when i jump the relay. are there fuses for the pump and if so where are they located? Any ideas would be very helpful thanks.

 

The only fuses are under the hood on passanger's side and under the dash on the driver's side.

 

So the pump will only kick on when you jump the relay? Which pins are you jumping? The solid yellow wire on the relay is the one that goes to the pump, if you have a multi-meter/dvom you can check that wire for continuity from the relay to the pump, and also make sure the ground for the fuel pump is good.

 

i checked for continuity and everythign was good i jumped they yellow wire to the black with yellow i also unplugged the pump and checked the power going to it and it was fine which has me puzzled and it is grounded properly. it almost seems like the problem is beofre the main relay becuase when i turn the key the main relay goes crazy clicking on and off. if anyone has anymore ideas that would be great

 

Those ludes can be mothers in the strange problem area. The first thing I would think of is the ignition switch. Is anything else acting goofy too?

 

no everythign else seems perfectly fine its turns over as normal but nothign happens except the clicking of the relay. i also found that when i put my foot on the brake the clicking changes patterns or sometimes stops.. im running low on ideas of what to do next

 

anybody got any more ideas to throw at me?

 

I can email you the wiring diagram if you want, you must have a wiring problem before the relay. I hate gremlins like this!

 

LOL Got the same problem on a '91 AWS , i thought it was starter problem (and i believe it is) checked continuity and got open' all over getting it in my mech next week will post pro's result

cheers and merry x-mas

 

does anybody think it could be as simple as a blown fuse even though ive checked them muiltple times?

 

ok apparently there is a fuse (#23) thats under the dash but the numbers only go up to #20 its located in the srs fuse block... Any idea of where that is located?

 

sounds to me like you have bad grounds somwhere
