I was wondering if anyone would have any idea on what to look for with this
problem I have with this vehicle.
1995 Chevy S10 blazer.
While driving down the road vehicle was running great, had just changed
spark plug wires, and spark plugs, when it just shut off, put into neutral,
and tried starting it, but would not start. Has never done this before.
We are traveling at this time, so hubby thought it was the coil pack, so we
had changed this along the highway hoping that was the problem but that was
Would anyone else have any idea what to look for, we checked all the fuses
and they are good. It has been kind of hard to start lately, but other than
that it run great.
Thanks, for any info.

When you turn the key to the ON position do you hear the fuel pump turn
on? Remove the fill cap and listen for a whine. If it has been hard to
start and now it won't start I'd bet the pump has failed. You MAY be
able to get it going again if you give it a sharp wack on the bottom of
the tank. BUT DON'T TRUST IT EVEN IF THAT WORKS.
Yes, you can hear the fuel pump whine but someone told us today, that does
not mean it is getting enough of pressure to start it.
So we are changing the pump, got it out need to go and get one tomorrow.

make sure to have your shop check the fule pressure if your vehicle is
kind enough to exhibit the symptoms at the shop. Reason being, some of
these dumped fuel from the fuel pressure regulator-possibly flooding
it out, causing it to stall. Hopefully they won't jump right to a
pump as this may or may not be the problem. Lastly-it's possible to
be fifty other things-good lucl! later jp

Well we changed the pump and it started right up, but now it will not idle
right, but it runs fine until you stop. It was not like this before it quite
running. Check engine light is not on, can I still get someone to tell me
what it is bye putting it on a machine, even though the check engine light
is not on?
Thanks everyone for your help.
It just has a really bad idle,sounding almost like there is a exhaust
leak and really bad smell of gas.
We also changed the fuel module, first thinking that was it.
It started right up this morning, before changing fuel filter I would
have to push the gas peddle down a couple of times to start, but didn't
have to this morning
The gas smell is not a good thing. First check ALL the fuel lines for a
leak. They can rust just enough that moving them causes a leak. If you
find it there good.
BUT It sounds like you may need to open the intake plenum and see if the
lines in there have broken (not uncommon) and check the pressure
regulator and injector spider for leaks. The good news is that if your
careful taking the top off the plenum you won't need a new gasket so you
can put it back together If the parts check out OK. When you open the
plenum a leak is easy to spot, just look for an area that is washed
clean of crud. The intake only carries air so ANY gas is a bad sign. BUT
it isn't a hard repair. If you need the parts take a look at
They have a "fuel nut" kit (fuel lines into the intake) and the rebuilt

Thanks for all your information on our problem with blazer.
Husband changed coil pack, and fuel pump. It was the fuel pump, because we
had no fuel pressure, but I just had it to the garage and he checked the
spider, and that is causing it to smell of gas an idle really bad.
So now all we have to do is come up with the money to get it. Hubby is going
to replace it himself. Garage said it was not that difficult to replace.
Is there any tricks that you know of when replacing this?
I guess they always say things come in 3's, I'm beginning to believe that.
No problem, Been through this on a few of my own Blazers. The only real
trick is to replace the spider AND the fuel nut kit (plastic fuel lines
that go from the back of the intake plenum to the spider) and make SURE
all the poppet clips are seated properly. Also while you have it apart
pull the EGR and clean it and install a screened gasket to prevent
another known problem. The site I listed has a real nice complete kit
that includes the parts and gaskets for a GREAT price. Once it is all
back together change the oil. All that extra fuel will end up in the
crankcase and can cause you problems.
Wanted to thank everyone for your opinions on the problems we where having
on our blazer.
We have got it figured out, and was fuel pump, then after putting the new
one on, we believe that it had more pressure and made the "spider" under the
penium, start leaking and causing it to idle bad with the smell of gas.
Now after $500.00 later, it is working great.
Thanks everyone, especially Steve from Near Cooperstown, N.Y.
What's the smell out of the tailpipe? Any carbon?
I'm assuming you ahve the CPI injectors and the 4.3 engine? When were
they last replaced?
I had a '95 Jimmy for 150K miles, so here's what I'd check:
1. EGR valve. Sometimes this gets stuck and/or clogged. Pretty easy to
2. Injectors. You'll have to see someone to check your injectors.
3. O2 Sensor. Even if the injectors are not bad, your O2 sensor may be.
This could cause starting issues.
4. Starter. The starter is placed way behind the front wheel well, AFAIK.
the soldenoid sometimes goes FUBAR.
5. Fuel pump. It is in the fuel tank and a bitch to replace. However,
there are codes you can scan for it.
years ago replaced 2-O2 sensors.
Don't understand why it worked fine up until it just stopped on us on a trip
to Ohio, wouldn't start and was not getting fuel so that is why we changed
the fuel pump, so don't think it would be the injectors. yes it is a 4.3
