I think that's the next mod for my ZJ.

Read about some of it here.
http://www.jeephorizons.com/tech/fan/

Although I want to hook up a thermostat and a cutout switch.
Anyone know of a site that has that setup for the ZJ.. actually
it doesn't have to be a ZJ as wiring is going to be the same
reguardless of the engine/fan.

The fact the Ford 8C607 drops in makes it very tempting. Nothing
like a mod you can back out of if it has problems. :)

Re: 99 wrangler hard start

i had a similar problem on my 97. If it's the fuel pressure system
(which it sounds like) shoot me a message and I can walk you thru the
steps to fixing it. A good way to test if its a fuel problem is to turn
the key to the 'on' position a couple of times and not start it. After
3 or 4 times see if it starts easy. If it does, that means that you
have an issue with maintaining fuel pressure.

And mpg....i get 15.5....it ain't a hybrid

Re: 99 wrangler hard start

No doubt, the fan probably made the biggest difference. The exhaust
may have helped too. However, I was addressing the t/body. It will not
change fuel mileage, or mixture. For that matter, nothing you did will
affect mixture, since the PCM will adjust to get the O2 content of the
exhaust where it wants it.
