I got a 1990 240 dl and today I wanted to install my tachometer, white guages, and since I was going to take out the instrument cluster i might as well pull the temp comp board and solder a bypass.
I had my neighbor solder the wire to pins 1 and 3 since he has more experience than i do with soldering. He finished it and it looked great. Installed the tach and put everything back together, and located the red/white wire coming from the harness. I was sure I put all connectors back correctly because I labeled them, and some of them cant be mistaken.
I tryed to be careful through out the whole process as to not diconnest or mess up andything other wires in the area.
Once i got everything back together and reconnected the battery, i tried to start it, but no. It was turning over no problem, but no fuel was catching. So I proceeded to pull the cluster out again and check connectors, checked and changed the #4 and 6 fuses, and I lossened the nut a little on the fuel line where it enters the rail and turned the key to the second position but no fuel squirted out. I also checked the fuel relay and it clicked twice like normal.
I am not too sure as what to do now, I hope i didnt fry anything, i dont know. Hope you guys might have an idea. thanks!
