Hey all, I've been tracing a problem with my 240 for a while now. It's a mostly stock LH2.2 car. Recently I've replaced fuel filter, done the upgraded IPD in tank kit, and done a basic tune up. Whenever I take it on road trips it seems to cut out and eventually die. It acts just like the fuel pump relay is going bad but it did it with a brand new URO relay and a brand new Duralast relay. It also did this while fuses 4 and 6 were jumped. I know that the relay also sends a signal to the ignition so while I was stranded on the side of the road I made the three leg bypass harness to completely get rid of the relay, which got me another 1.5 hours to my destination. Now I'm 2.5 hours from home and hoping to figure this out before I leave saturday. Any ideas?
I was thinking bad wiring could be causing the relays to burn up prematurely by putting too much load on them. Or maybe the upgraded fuel pump is too much for them to handle?
Also maybe this is normal, but I did notice that for whatever reason my car will still run without fuses 4 and 6 in place! I thought that would completely cut power from the pumps. What am I missing??
