I'm a newbie to this forum, and I'm pretty much at a loss. I have a 1995 plymouth voyager w/ 3.0 liter and about 115k on the clock. It was running perfect until recently when it died without warning in my garage. I can crank and crank without so much as a sputter. I can still hear the fuel pump and fuel is making it to the engine. The fuses and relays seem to check out just fine. When I sprayed starter fluid in the intake it fire right up (not well but still turned over) then died. I also did the key dance thing with code #'s 12 and 37 coming up. I understand the 12 but the 37 doesn't make sense to me. I'm somewhat of a novice mechanic but willing to try just about anything, and any advice would be appreciated.
