I hear this is an ongoing problem with the ford 302. I have read about this problem across multiple ford truck/mustang forums.Lets hope we don't spend years ...
It has been a while for me, but I have fixed a couple of Fords with this
issue in the past by replacing the ignition module. You should see it
connected to a heat sink (google it to find the exact spot). I recommend if
you do choose to replace it that you go with a motorcraft one and not any
other brand, and make sure to use the puddy that comes with it when putting
it back on the heat sink. Beyond that, no start diagnosis has you verify,
fuel, spark, and compression. One will be missing.
Usually it is cars that sit a while that get shit in the airbox making
nests. I have seen chipmonks do it a lot. My dad is a car dealer and we
have a few cars for parts or that are just toys that sit a lot and those
bastards love making nests in there. Most of the toys are kept in garages
or storage and sometimes get mice in there usually try to keep moth balls
in them and pour a little ammonia around the car on the ground seems to
keep the critters away.
My 91 f150 302 does that in the morning at first start and when heading
home from work,but it just happens initially when first started,three
starts and he stays idling,I replacing the TPS last year corrected it for
awhile,but not for long.As soon as I get my 96 ranger top end rebuilt and
back together,,I'm gonna start deconstructing the 302 and rebuild it as a
347
I have a 93 Chevy S10 with the 4.3. It would do the same thing. It would
run until it got up to temp, then shut off. There is a little module inside
the distributor that I replaced and it runs like a champ now. But man was
it aggravating as shit to figure out. I replaced almost every little thing
I could think of b4 a buddy told me about the distributor problems.
Yeah, I had to let it sit. I knew it had spark and fuel, so that narrowed
it down to electronics. Not my forte. Just a little sensor or module of
some type. Expensive fix, but necessary. I have a Bronco 302 now, hopefully
I won't have that same issue, although last year it just died on me and the
sensor they replaced on the Bronco was only about $30 with labor.
Hope the distributor is your problem man. I've heard of this problem too. I
read where one guy thought it was the MAF sensor but it turned out to be a
problem in the PCM. I really like this generation F series. Had a 94 but
had to sell it to get something bigger for the family.
I've had the EXACT same problem. On my 89 F150 EFI, I took it to the shop
and it cost me $300 to replace an electronic component, I believe it was
for ignition. Just replaced a small module or sensor, but ran perfect after
that.
My Step dad had a mouse/mice get under his hood and the little SOB's chewed
up some wires,forget how much it cost him but i know it was way to much.
Good luck
