need relay help
Hi, I have a 1991 Ram 50 with a running problem that I'm trying to track down.
When you turn the key to ON, the MFI fuel injection relay clicks. Start and run the truck and the relay will occassionally click, followed by a stumble, but most times the thing clicks, the engine chugs and dies. Sometimes the relay clicks madly, and its a definite audible click. You can even feel the relay with your hand and feel it clicking. I have checked the Chiltons and I'm supposed to be getting 95Ohms when connecting pins 2-5 and 3-5 but I'm getting closer to 125Ohms. Is this thing toast? You can't find them anymore, anywhere. Can someone please help me diagnose this problem? Thank you in advance.

RE: need relay help
Can you just put in a Bosch relay, or is there something fancy about the OEM one? Hack a wiring harness if you have to, but my guess is that you're going to need to replace it.
