Nicholas Kinney: I have a 1994 chevy cheyenne 1500 4.3 v6 vortec / obd1 says electronic spark timing error .my truck has been setting 4 years now .I don't wan to get rid of it because it's powerful and gets good gas mileage 45 gal.tank of gas and 1,000 lb.+ load 240 miles,uses less then 1/4 tank of gas .I can drive to town & back 60+ miles all week and not have to get gas.
Carlos S Negrete: Good video and you did a fantastic job explaining it.
nicci82np: Starter bolts broke off when I went to start. So I hecoil 29/64 but wont hold. What do I do? Its blazer 96 4.3v6
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?
Boo Homie: thanks for posting, replacing the spider injectors today on my 4.3 vortec
smoknjoe73: Thanks for the vid. Plan to attack this same issue on my 95 astro. Nowhere near the clearance under the hood but same deal. This helped me understand it better. Thanks again.
Quattros23: I have a s10 xtreme with the 4.3 n mine has been giving me problems staying running when it starts. is that what yours was doing?
George Mooney: Hello there! Thank you for this helpful video. By the way, I hear many people keep on talking about Stutterolax Secrets (do a google search), but I'm not sure if it is really good. Have you thought about system called Stutterolax Secrets? I've heard several great things about it and my cooworker completely stop his stuttering naturally with this program.
Ivan Poltiov: Hello! I'm Austin.I did -10 lbs in 2 month.Go to hawght.so\#R3lC
Igor chirkev: Hey! I'm Kayla.I did -45 lbs past 7 days.Go to hddiet.gs\#Cdmk
vinman1029: All pressurized at the same time so it does not matter.
Bobbie Brooks: I'm doing the same thing to this 95 blazer 4.3. But on the fuel line side it's just covered in this black crud messy stuff. Regulator side is perfect. Any ideas??
cameraeye49201: many thks mine hasn't gone bad but if it does ill know what to do
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".
gloria Ramirez: Nice job , good instruction.
james dutton: just put a marine intake on. it has external injectors on it.
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.
goo0280: Hey nice spider injector video. I have the same issue. my question is what was it doing before? Mine smells like fuel alot but it trys to start but it wont until I give it gas. then it idles rough even though I have replaced the spark plugs. the fuel pump and filter are ok. whats you guess on this?
mrnorthwoodsbob: Just wondering if you have any more videos ...perhaps on working on this same models gas tank ???? I have the same truck ,motor and having a real bad gas leak coming down the frame only when its running ...when I shut it down it drips fer a bit and then stops ....You can e-mail me back with a reply @ email@example.com
mrnorthwoodsbob: Yours is a different fuel injection system theirs two for the 95 year one has a round almost air cleaner like top this one has that long plastic thing that says Vortec on it ...whole different ball of wax
Joe Bezzy: Witch lines go to witch port for the fuel injectors?
Benjamin Johnson: thanks for posting this, i'm having trouble locating the complete spider replacement.
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 thks again
Darien Masterson: I had this problem for along time and just got it fix...it was all of those problems i fixed it with the spider...didnt see an improvement for a while so we also chang spark plugs and wires after awhile i was amazed to see the results...it runns great now and flying down the road
MistaGooch: all i can say is thank you! thank you! thank you! you saved me a ton of money and headache with this quick easy fix on my 2001 chevy tahoe. you definitely get a thumbs up for this video as well as a new subscriber.
Jay Jones: and always leave ur garage door closed while ur motor iz running so u can breath great amount of exhaust fumes kids aways remember ventilation iz bad 4 u lol
dumpstercrust: whats the bolt pattern and torque for this?
Boyyoee1: Does it matter what fuel line goes where? Off of the spider
Javier Rodriguez: I have a 1995 Chevy Astro Van 3.4L V6 Engine and its giving me problems of backfiring, rough idle, lost power, it tries to start but won't stay on. I have replaced the fuel filter, air intake filter, distributor cap, wires and spark plugs. Following other videos somebody recommended to clean the EGR valve which I did. Also fixed some leaks on the vacum hoses. I tried to start it and wont stay on, some explosions come out the exhaust and white smoke through the air intake, any ideas?
charles horgen: I have a 94 blazer with the 4.3 vortex and i have had problems of the cylinder filling up with fuel, replaced everything that deals with the fuel system but the spider unit. I am looking to replace the spider. would you have any ideas?
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 great!
riscen42: I like the way you show the video and explained how to replace it with the does and don'ts Thanks
jeddmow: Help me out really well, thanks! :)
scottwagoner1: 10 out 10 you did a great job just want you to know it was all i needed to fix my truck.much respect to you thanks again
Germain Gonzalez: awesome video. helped me out a lot
willie sowell: I have 1992 S 10 Blazer starts but won't stay running everytime I turn the key off and on I do not hear the fuel pump but the first time if I turn the key off and wait a few seconds I hear the fuel pump could the spider injection be the problem
hawker01: Thanks for making and posting this vid!!!!!!!
doughubble93: This vid is informative and helpfull
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.
spikee2727: we put a new fuel pump & lines in our 1995 blazer ,.we filled it with gas ran it for awhile than drove it for 2 miles shut it off it will not start the pump goes on but it will not start..if you prime it whith gas it will run stop the primering it shuts off Spike
Andre Kendall: So my 99yukon is misfiring. I ran a code check and 7 is misfiring...i jus did a tune up 2days ago... An its still studderin.. Y?
Damien Nicholas: so about how much am i lookin at for a 1998 4.3 for the full kit? $300? I really dont know whats wrong, but have heard of ppl trying this and that and nothing seems to fix it but changing the fuel spider. I paid for the truck after inspecting it, drove it home, stopping for gas a couple times.. (6 hour trip back home) let it set for 2 days and now it will not start. cranks good, but wont fire up.
Dj Hayes: chevys also have a common problem with fuel filters, prob might want to change that out as well.
fins5150: Thanks for the great breakdown! I wasn't looking forward to doing it.
Govenor73: Wow, this has got to be the most thorough and helpful repair video I have ever watched on youtube, thanks jfrost for sharing this post, I still cannot believe how specific this video is!
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 leak.
