This is Under the Hood.
Welcome to the Under the Hood Show.
We are glad to have you with us.
Russ Evans is here to answer your automotive questions.
Thanks for joining us Under the Hood.
Shannon Nordstrom, World Traveler is here to do the same.
Welcome, hoodies.
Thanks for tuning in so we can help you tune up.
I'm Chris Carter here to answer your calls at 866-594-4150.
How long before your next journey takes you out of the studio?
Well, I found out just last night that I'm going to be going to Louisville, Kentucky on
behalf of ARA.
It's Louisville.
Louisville.
You know what?
My daughter has a roommate from Louisville and I've been corrected on that.
But no, we're going to be going to Louisville to tour some properties for a future convention
site for our trade association and we're hoping we'll have an opportunity.
We've made some connections to stop in and drop off a donation to our industry friends
at Grade A Auto Parts in Louisville.
And they were unfortunately right in the flight path of where the UPS plane went down.
If you wondered about all those cars that were there, that was a automotive recycling
set.
However, he has been a speaker at our industry before.
First-rate fellow, I don't know him as well as others in our executive team, but I definitely
know who he is and he knows me and we're hoping we'll have an opportunity to stop in because
we've got a gift.
They've started a GoFundMe, but we want to give something direct to the families.
They had employees that were unfortunately had their lives taken, one in the hospital.
It was a horrific situation.
So I'm going to go do some, I think, very important industry representation and that's
something that just has come up in the last week here that we've decided to do and tie
it in with our visit we have to do down there at the same time.
So that's kind of short notice, but I should be back on Wednesday night late if these flights
are all straightened out.
Everything normal.
Well, it should be normalized by next week, right?
Okay.
Yeah.
I'm going with it, but no, I'm supposed to get back.
I'll leave it Tuesday morning on that 5 a.m. flight that goes to Minneapolis and then come
back and come back into Sioux Falls on that 11 p.m. flight that comes into Sioux Falls.
Nothing can go wrong there, right?
Yeah, exactly.
Minneapolis is usually pretty good.
It's the DFW, one of the Denver one that gets sketchy.
Yeah.
I'm glad I'm going east instead of west.
You can rent a car.
If I get that far, that's for sure.
866-594-4150.
Let's go to Oklahoma and talk to Pat.
You're on the end of the hood show.
Pat, what can we do for you?
Yeah.
I have a 2016 Chevy Colorado and the fuel gauge wasn't showing any fuel and I replaced
the fuel pump with the fuel gauge that's attached to it in the tank, gasoline tank,
and it still isn't working the fuel gauge.
The next step I need to kind of explore or look at.
What's the fuel gauge reading before and after the whole bit?
Full or zero?
Before it said empty.
Then afterwards it still said empty, so when you start it up, originally you know how the
gauges go from empty to full and then back down and then reset themselves.
It does all that, but it won't ever...
Won't read.
All right, full even though the tank's full.
Here's your next step.
You need to plug a scanner into the vehicle and a lot of them that read just your basic
engine codes and data will read fuel percentage on that screen on the PIDs.
You need to find a scanner that reads that, whatever it takes to do it, and see what
it says.
If it says zero percent fuel or two percent fuel, then you're not getting communication
from that unit in the back, which could be the part you just replaced, but let's just
assume that's good, but you replace it.
There was no change.
Probably something in the wiring coming up to the computer and into the vehicle, body
control module from that.
But if it reads 80 percent, 50, 20, 60, whatever it is that you've got in the tank, you
probably got a bad instrument cluster, got a problem internally in that.
Which is more unusual in those newer ones.
Very unusual.
We have not had one ever so far.
It is very possible you have a broken wire and if I was going to go chase a broken wire
on a 16, I'm probably going to be looking at a ground or an open in the wire somewhere
in the tank area within four feet of the tank would be my likely guess.
16's pretty new, but it's actually pretty old now.
Ten years.
Ten years.
Right.
We're going to start seeing some of those things pop up, but we have not experienced
this yet in one of them, but it's possible that you could have this happen.
So I would look in the tank area and make sure of the ground above all else right near that
tank that it's grounded well.
It's not corroding there.
That would be a good thing, but the scanner is going to tell you what you really need
to know and that if it's getting signal up to the body of the vehicle or not.
That's the most important thing.
No sense in chasing any wires if it says you've got 80% fuel at a module.
It's going to be beyond that.
At that point, you might try to, on this vehicle specifically disconnect the battery
for 10 minutes and hook it back up and may reset.
Some weird things happen.
You see rebooting computers, all sorts of stuff happen.
Okay.
I did have a bad battery also, and I did replace it too about the same time.
Before.
You did the fuel pump, but this gauge was already not working when you replaced the battery,
correct?
Correct.
And then it's probably not going to change anything.
It is very important that when you're changing batteries, I had a customer this past Monday
that said that their battery was dead.
They had AAA come out and jumpstart the car and they had left their lights on.
So the battery they felt was going to be okay, but their heater controls no longer
work.
You need to reset that and now it'll work.
And they thought scanner or what is it?
No, and not every car can be disconnected because sometimes you need programming and you run
your world of hurt, but on this particular car disconnected, they did and it fixed the
problem.
Now, if you ever have questions like that before you go and if we're not on the
air, you can go to the battery shop channel on YouTube.
That's one of our partners and they have spent some great time there, our partner
Clarios, putting together things like this about jumpstarting cars and it's more than
just how to hook the cables up.
It's like, well, you might have a module shut off on you afterwards and here's how
you would go about fixing it.
Things like that.
It's very resourceful.
Pat, thanks very much for the call.
Good luck.
I find that interesting as someone who is a casual listener to this program.
Can you say that?
Can you say that?
The fact that you listen every week, casually, the fact that we're talking
about a 10 year old GM that's a 16 automatically would think, well, those things
had a ton of trouble with the with the dashboard with the clusters.
Yeah, that was that's old news.
And that's it's interesting to me that that was old news.
It was a 2006 problem.
Yeah.
And it was that was what the answer was for years on things like this.
It was always that.
And now we're talking about even though it's 10 years old, that's no longer
an issue.
And that's how people get in those.
The interesting thing, the 2016 cluster problems are not normal.
2006, 2005, 2004, three, two, one.
There's whole industries, big stuff.
The clusters were a big issue.
Okay.
2003, four, five, six, there was not a lot of problems with the radios.
2016, there's a bunch of problems with the display board and the human
interface modules and the touchscreens when they went to that newer
technology, it wasn't perfect.
So they solidified clusters.
And then they got another thing that we see some one else challenges
with throw it.
So, interesting.
866-594-41, 5-0, that's the number to reach us here at the
end of the hood show.
Let's go to California and talk to Ron.
You're on the end of the hood show, Ron.
What can we do for you?
I have a problem within a problem.
I have a 1980 Ford F-250 with the 460 and it has an
Holley 850 double pumper on it.
It's been sitting for five years.
I've dumped the fuel out, new fuel, new lines, new fuel pumps,
new filters, the whole rigmarole.
I had it running a few weeks ago and it ran for about 10
minutes, no problem.
I went back to it last weekend, couldn't get it to fire,
pulled the fuel line off at the carburetor to make sure I
had fuel, I did.
And in checking for spark, I touched the coil that was
hot to touch.
I don't ever recall finding a coil that's hot to touch like
that and I'm wondering if it was from cranking the motor to get
it to start or if there's a problem with the ignition
that's prohibiting the engine to fire.
In the end, I did use some starting fluid and I got it
to fire for about 10 seconds and then once it burned that
up, it wouldn't fire.
If that's the case and it's just running out of fuel, you're
not getting fuel to it, so we know we have spark, but if you
leave the key on in the on position, the engine's not
running or you crank it for an extended period of time and
then it's on without running, yeah, it'll heat that coil up
because at the lower RP, at higher RPMs, it's fine.
It's pulse width because it's on and off, constantly
and it'll regulate itself, it'll be fine.
But when it's cranking real slow, the on time of the
coil is longer than that off time and it heats up and it
does, it'll get very warm.
They originally had a resistor in the line, the power line
going to the coil or they had a resistor coil on it.
If you do not have a resistor in either, then it needs
one in one of the two.
Either you need a resistor in the coil or you need a
resistor in the line.
Otherwise, there'll be a backup.
Okay, so I need to figure out what kind of coil I have.
Yeah, well look and see, look at the wiring diagram and see
if it shows resistor between the ignition switch and the coil.
If it shows no resistor, you need a coil that has a resistor
built into it.
If it does show a resistor in that line, you don't,
you put a standard coil on it with no resistor.
Then you got to find out what's wrong with your
fuel while you're not getting any fuel to it.
You can take the line off at that carburetor and disable
that coil completely so it doesn't have any ignition source,
no spark, and crank it over and see if you're getting,
if the fuel pump's pumping fuel up to it.
Maybe you got a restriction in the line somehow, rust,
