I'm having an electrical issue with my fuel system. Its a 92 240. When you turn the key to "run" the fuel pump primes just like it is supposed to. It isn't until you try to start the car that the problem comes up. We have to start the car by "hotwireing" the starter. It was working just fine for a while. Now, when you hit the starter, the EGI and EGI pump relays click, alot. The fuel pump doesn't pump at all during this. When you let off of the starter, the relays continue to click and the pump kicks on and off, kinda like - - - - - with each - representing a burst of fuel.
With the little bit of knowledge I have, I thought the pump might not be grounded properly, so I checked all of that. I checked every connection and sure enough, the pump is grounded to the chassis just fine. Being curious i also checked to see if the relays where grounded, and they are. The interesting thing I found there was with the EGI relay. With the key in my pocket, I was getting battery voltage to 2 and 3 and a partial ground on 5. No reading on 1. I just went to double check. The was in the Run position for a few minutes now and the relay is hot. I've exhausted my electrical knowledge. Any help would be appreciated.
thanks
