Default No start when cold, not even with a jump

My mom's 94 aerostar 3.0 v6 refuses to start when cold. Yeah yeah, i know this isn't about a ranger but its a ford and i tried to jump it with my ranger and I'm not a member on any aerostar forums (if there are any) so I figured I'd give it a shot here.

The battery is only a year or so old and it's a pretty good one. But the battery is likely irrelevant as it won't take a jump or start after I've had a charger on it for a few hours. Whenever it warms up outside it starts up with no protest. I've also all but ruled out fuel line freeze as it will fire while cranking for a second or so but wont actually start. I'm guessing the fact that it even fires means fuel freeze isn't the issue though i could be wrong. I replaced the coil pack about 6 months ago when it was refusing to start when it rained as when I removed the access panel under the dash and tried cranking it at night when it was wet outside i could see the coil pack arcing. Haven't had any issues starting when it rains since then. I didn't replace the plug wires but they are quality motorcraft wires that look very clean as if they were replaced shortly before she bought the van a year ago, the distributor cap also looks like it was replaced at the same time. My mom is broke as hell and so am I so taking it into a shop isn't an option. Whatever diagnostics anyone can think of will have to be done by me. I have access to just about any tool I may need as my dad is a service manager at a ford dealership so he can let me borrow whatever but since they're divorced he isn't going to take the thing into his shop for free diagnostics or repair . . .


Any ideas?

You said you have the battery on a charger, does it crank while its warm, but not while its cold. I think its worth swapping batteries just to be sure.

It cranks fine regardless of the temperature. It starts without hesitation when it gets above freezing. When it's cold out though it cranks and cranks and sometimes sputters to life for a split-second but then dies... It also only sputters for that split-second if the throttle is wide open...

And yes, I've tried jumping it with the same results.

No need to try and charge the battery or jump it then. I have no idea man, that's a weird one. Hopefully someone chimes in with an idea or answer.

Fuel injected, right? I'm going with moisture, try some gas dryer when you get it fired up.

EDIT, dammit, I agreed with Bruce.

Yeah it's fuel injected.

I'll try the gas line dryer tomorrow morning. Any particular brand work best? The gas station up the road usually has heet in the yellow bottle if that's a quality product and what you're talking about....

Any other ideas? I want as many suggestions as I can get so I can run through them all at once rather than wasting gas running back and forth between her house and mine to get online....

Any brand should work, as long as its isopropyl alcohol.

If you get more ideas just try one at a time, that way you know which one works. Heet is probably the best.
