1994 Eddie Bauer Bronco - Extreme Heat

I'm the original owner of a '94 Bronco, 351 cid with 125,000 miles. It
has a new cooling system - radiator, water pump, hoses, etc. (no
leaks of water, oil or other fluids)

During the extreme heat ( 110 - 117 degrees in Las Vegas) the truck
shuts down. It acts like what we used to call "vapor lock - boiling
gas". The truck seems to starve for gas and air. It runs irradically
[sp] when I do get it started after a short cool down to get it home.

It will drive fine most of the day until the heat gets extreme and
this only happens in the summer months. (past three summers). The rest
of the year every thing is fine with no trouble what so ever.

Any ideas would be helpful!

Oren

Hi,

I live in Vegas too. I never buy gas from any station except Chevron
especially during hot weather. Chevron doesn't put any corn in their fuel.
Many of the other brands trade gas and you never know when you get gas
with alcohol in it. While people will tell you that it is JUST FINE to run
gas with alcohol in it, don't believe it.

Take a small amount of alcohol and the same amount of gas and put it in
an open area and see which evaporates faster.
Now imagine the fuel with alcohol in your fuel system on a hot day.
As it circulates above your engine, it vaporizes.
Give the good gas a try.

Vapor lock is not a likely problem. Be sure you have a good
fuel filter. If the fuel pump and regulator are keeping the
pressure in specs, it won't vapor lock at the pressure
modern EFI systems operate. You can buy a fuel pressure
test guage from places like Pep Boys for about $40. It will
work on most current EFI systems.

The first thing I would try is a new ignition control
module. Yours should be mounted on the left fender apron
near the rear. It is mounted in a heat sink which can cool
it relatively quickly compared to the old location on the
distributor. A bad module will not necessarily test bad.
Any time it is running, it will likely test good. When you
install the new one, be sure to use a good thermal paste or
grease or, in years past, called heat sink grease to help it
cool and greaty extend it's life. It is probably a fair
idea to replace the grease every couple of years if you find
yourself with nothing better to do some afternoon while
waiting for the bars to open. Many electronics stores and
computer shops have the stuff since it is used to attacth
the cooling fan to the CPU in computers and other similar
applications.

If the fuel pressure tests OK and you have replaced the ICM,
your next step should be to get a complete diagnostic scan.
Many independant shops have the equipment to do this but,
the best equipment is, sorry to say, in the hands of a Ford
dealer. That does not mean a particular tech will be able
to correctly interpret the data or, that the fault will show
up in any particular diagnostic session. Intermittent is
the longest four letter word in the English language.

Good luck
Lugnut

Under this heat any thing goes, trucks sitting idle (waiting for
accidents to clear) have previously melted pavements.

>pressure in specs, it won't vapor lock at the pressure


Will check the system

I tend to burn things up when it comes to wires! Looks like I can
handle that module.

>install the new one, be sure to use a good thermal paste or


Does this go under the heat sink and the ICM or just one or the other.
The heat from the road under the fender is HOT. The other day the
compass / temperature gauge stopped past 130 + sitting at an
intersection.

Two things on my list now.

Thanks

After 3-4 years worth of rain in this fall, doesn't help if water
night be in tanks at stations.

Thanks,
