[QUOTE="Mdub707, post: 371002, member: 107"] Ok, managed to find ONE of these relays at the junkyard. I checked probably a dozen or so crown vic/grand marquis type cars, the only one that even had the setup that contained this one relay was a 97 grand marquis. I checked older and newer and it was the only one... maybe just got lucky, who knows. Anyways, last night I did something that kind of set me back. I accidentally touched the multi meter probe against the case of one of the FICM's I have here. Oops. I wasn't sure if it was damaging or not, turns out it was. Get the new relay in, have the gf turn the key and test probe the FICM. 0.0 volts across the board, no injector buzz, nothing. Crap. So swap in my other FICM from the back seat (newer 4 pin). Try again, I'm getting a solid 48.6V across the board now. Try cranking truck again, and no smoke still. I test probe the batteries as they are getting weak from all this cranking now, and they're reading something like 11.6V now, so they're dying. This is the first I've had the FICM stay above 48V consistently, but still no smoke. So with weakish batteries would that cause something to not fire the injectors? The batt's should be up more like 12.5 and above right? If I try jumping it will it start? I know it seems like it'd be easier to just try it, but honestly it's not, I will probably have to call AAA to come with a jump box to try it, and I don't want to call them for nothing. I might stop and buy a battery charger/tender deal tomorrow after work. So now I've got the FICM going at 48V+ the whole time, but still didn't see smoke. I didn't crank long either, as the batteries are getting weak. Any help is appreciated, this is driving me nucking futs. [/QUOTE]
