Jibber Yoda: dude sounds just like danny mcbride... freaking kenny powers too. lol.
tman594tb: When you take that top piece off do you have to drain any coolant at all or
is it dry inside by the fuel pressure regulator? Just curious if I need to
drain anything before doing this.
cbthethird: fixin to have to do this to my 98 gmc with the 4.3. So many things have
broken on this truck so far. had it since late 97, bought new. In 110,000
miles of light use, it has been nothing but problems.
Great video though. Thanks for uploading.
automotiveDIY: ahhhh you didn't get the updated mpfi design spider :(
00394994: Well done, no BS, music or other crap, right to the point, thanks for
jfrost77hd: Hey thanks for watching!
ScottysDetailing: AWESOME video! i have been looking for this how to for over a year. how do
you know if the fuel spider or nut kit is bad? my 97 V6 astrovan has a very
hard start, so bad i had to replace the starter once.any help would be
fendertele1988: Any idea if the symptoms you described could also be solved by replacing
the fuel filter? a mechanic friend of mine told me that that was the
solution when i told him my truck was sputtering, having trouble starting,
smelled like it was running rich. thanks in advance!
ImShannon: Wow man great video! I have a 93 and a 94 S-10 Blazer and I've replaced the
fuel pump in both of them, with a Delphi. Still neither of them will run.
Fire right up with a shot of starter fluid but then cut off. Maybe this is
my problem too? Was afraid to go into the plenum to get into this, but
after seeing your video it doesn't look hard at all. A hell of a lot easier
than those fuel pumps!
undercoverLsX: L31 had a very lean smell, idle issues, and bucking in gear. This solved my
problems. I thought it would be a vacuum leak considering the vortecs
fc196582: Thanx Man!!!
GoldOlds94: Did this to my 94 olds bravada. Went from 10 mpgs running like s#^t to 23
mpgs running like it just came off the assembly line. Clean the egr valve
too!!! Clean with gas everything
timcat100: Wow...googled this for days and this is the first I hear about this GM fix.
Now I am gonna have to Google this part number. I don't need to do this
repair right now but I will do it before it kills this newer van I
bought...don't want to kill it like my 94. Thx eh!
Paa Hawkins: excellent... 2nd video on this job I've seen. Mine is a 95 Astro with the
horrid rough idle, and fuel smell everywhere like someone dumped gas on my
engine after I drive it. Since I changed the IAF, EGR and a few others the
fpr and spider is the final straw! LOL Hopefully
Lamont Pettway: love your video you sound like my old shop teacher
aode06: DONT FORGET TO CHANGE YOUR OIL MY FRIEND, ITS FULL OF FUEL FROM THE BAD
SPIDER AND WILL DESTROY THE ENGINE BEARINGS
Kyle Whybrew: its a similar setup but its a bit different. all the connectors come from
the top directly into the fuel body instead of through the back of the
plenum and you can get a replacement with electronic poppets (gives me
17mpg on a good or bad day). the electronic poppet version doesn't cost
that much more than its predecessor. just do a search for "mpfi 4.3 spider".
Jeffrey Waters: Help me out really well, thanks! :)
David Jacobs: when the truck would not start at all, did it "kick back" or almost
backfire? I have a '99 GMC 1 ton van with vortec 350 has not started in
months. when problem first started to happen I could get it to start by
feathering the gas while cranking. Crank sensor replaced so that is not it.
I was only getting 9 mpg out of it the last time it ran. Any help would be
ebrewste: Great video! I just did the same job and this video made it go a lot
jfrost77hd: As much as I can, lol... Try to get one up a week but doesnt always happen!
THanks for watching!
chuck e how: Hey just want 2 say thanks 4 the video it should help a lot.
cameraeye49201: hey thks ..never had to do this on my 95 blazer and didnt know how.but i do
now >:) thks to ur video thks a bunch..just bought my wife a 97 blazer and
having problems with the neutral safety switch working then not
working..pisses me off but i will get it fixed one way or another...hey
Digital Phoenix: I hate them damn spider injectors. Why they made that design I don't know
but I do love the TBI though.
bishop of beats: thank you so much I don't know what I would have done what up video
King Jon: Im glad you posted this video!! I had the same problem with my 4.3!
Laquetta Ross: I have a 2000 GMC Jimmy that is not starting when temperatures are below 40
degrees. a mechanic told me that it could be the timing since this is a
different engine from the original engine. but now I have seen this vid and
think it maybe the injectors. my CHECK ENGINE light is on and the code
always reads FUEL CAP when checked. I was going to sell my Jimmy but I will
try this first. should I do this during the winter time to be sure that
this is the problem?
ScottysDetailing: How often do you post videos?
MrCharttn: Great video! This has the best lighting of any engine video I have run
across. I could see everything you were pointing at.
Boo Homie: thanks for posting, replacing the spider injectors today on my 4.3 vortec
jfrost77hd: @gamefreak501 Sweet sounds good man! Thanks for watching!
ICEProducer: @jfrost77hd Awesome thanks again. I have been having the issue with my 97'
Bravada. I replaced everything from the fuel pump all the way to the engine
and the truck still stalls when it warms up. I have seen the issue with the
fuel pressure regulator in many posts and made me think this is the
problem....I hope it fixes it i like my truck lol
Kyle Whybrew: Yea i killed a red 2 door blazer that way, don't think ill ever piss around
with regulators or poppets again. Just replace the whole unit or it will
dick fleming: have you had a problem with a single injector that doesnt work until the
engine is fully warmed up ? just had my 96 tahoe intake man. gasket
replaced by a local shop. spider injectors were replaced in 2008 with an
a/c delco #217-3029 upgrade. has new rotor and dist caps,plug wires &
plugs.compression 195 lbs and good spark.
hawker01: Thanks for making and posting this vid!!!!!!!
r8er4everd: I know the back of the truck is full of snow, but I bet your wife would be
allot happier if you at least cracked that garage door a foot or so when
running a engine... :P Unless fixing the runablity issue was for a much
more sad purpose then being able to drive it...lol Other then that great
vid dude. Was well presented, informattive, and I am sure that allot of
shade tree's will be used because of it(weekend/shade tree mech's).
MrBitchtits76: would this be similar to a 1998 gmc sierra with a 5.0? i have intermittent
starting issues and fuel in my oil
trent young: very informal video. my brother has a 94 s10 blazer with the 4.3 and he got
it fixed at a dealership but we could never figure it out by ourselves.
this gives us a good idea for next time
paulsjunkcars: how much was the spider injectors?
jfrost77hd: @rafi77 Hey your welcome... hope it helped!
indybob: WOW awesome. Not near a nightmare as I thought. THANK YOU.
tbrandlein: i got 2001 blazer when i drive it you smell gasoline anyone know wht my
problem could be? only when you drive it though idk if its bad regulator or
pcv or it hs to be in the front.
dollman0: Gotta love those plastic fuel lines
fins5150: Thanks Bro big help... I couldn't for the life of me get the T30 nut off...
Tried for an hour, said the hell with it...hope no leaks..had it replaced 7
or so years ago i think....on a side note... I think that due to the
Ethanol in gas now, it's the root of the evil.... putting straight gas in
for now on.
fins5150: Thanks for the great breakdown! I wasn't looking forward to doing it.
dumpstercrust: whats the bolt pattern and torque for this?
Hector Aldaz: Thanks for the awesome video I have the same motor and I know now what is
my problem check my lines on the gas tank, my blazer did`t want to start I
saw the video and now my blazer is really good thanks.
Chris Chiampo: Great Video Better Than AllData can explain keep them coming thanks
jfrost77hd: I hear you... always had good luck with the TBI 4.3 Thansk for watching!
mistydawn1983: i have the same problem and would like to ask u a question
