1990 K5 wont turn over
 

Even more problems with the 1990 K5 now after taking it for a short ride about 4 1/2 hours ago, the truck will keep cranking but it wont turn over. I have no idea what could've happened. I literally let it sit for 4 hours and I come back to a truck that won't start up. I looked under the truck near the gas tank and noticed there are hoses that are cut. One is on the rear differential and the other looks like it's going to the gas tank and the third one goes below the body mounts and is clipped together along with a bunch of other hoses. I'm pretty much screwed so now, so I really need some help.

Have you checked for spark? Remove a plug wire from the spark plug and hold it to the block and have somebody crank the engine. See if there is spark.
What about fuel to the tbi? ahve you looked into the tbi while cranking to see if fuel is being delivered?

I was thinking the spark plugs were the cause of this. This is going to sound extremely stupid to you but I'm still learning, where would I look to see if there is fuel being delivered to the TBI?

Remove the air cleaner. That is where the TBI is located.
No worries. If you don't ask you won't know. Nothing wrong with learning.

I took off the air filter and I was told By one of my friends to pour in a little gasoline And see if it starts. I have two questions: where do I pour the fuel and how much to pour?

The blazer is back up and running, I poured some gas into the tbi and its running good now.

when you take the cover off for the air filter you see 2 injectors, have your friend crank the truck and you should see them mist down into the throttle body. hopefully what you did fixed the problem but in the future you know how to check if you are getting fuel.

Yeah I fixed the problem, I started her up at 3:30 and it was running fine, took it for a ride.

hmmm im confused, you poured gas into the TBI and its running now? why wouldnt it start without putting the gas into the TBI? thats a mystery there... unless fuel pump lost its prime or something. any other details we might be missing from this?

Nope, all I did was just pour a bit of gas into the TBI and it runs fine now. I made a video about 3 hours ago:

No details that I left out either.

nice video man.... love seeing them K5's still going strong... nothing against the S-series trucks because i have owned them also... but the K5 is where its at in my book!!!

so whats the plans for this truck Parasite? or should i say when ya removing them running boards? that was the first thing i took off mine even before i drove it home. just something about them and there mounting holding the moisture against the rocker area of them trucks...

Hey, thanks Ck1500. My plans for the truck is to fix the rear window, install new headlights and I will be doing an oil change this weekend. I will be driving to this truck to and from school and the occasional off-roading, nothing too extreme though.

whats going on with your rear window? i have had mine torn part quiet a few times, maybe i can help? did you post something about it here? if so i might of overlooked it.
let me know if i can help.

and most importantly let me point out.. to ENJOY your Blazer, i was guilty myself of not enjoying it alot, and fell into the internet and all the "HAVE TO HAVE" upgrades!! which is sad... i fell into the peer pressure of people telling me i have to have a lift kit and a Dana 60 front axle, and a corp 14 rear. unless your making a OFFROADING machine.. dont fall for it!!! your 10bolts will hold up fine to 33" in stock form all day long! the sad part when i think about it, is my Blazer has been in the garage more then its been on the road now after all this...

I have a thread for my rear window problems. I sure have been enjoying my Blazer, I've taken it off-road twice and had a lot of fun with the old girl. I'm sorry to hear that you spent most of your time with the truck performing upgrades. I'm not doing ANY upgrades or performance enhancements. I changed the oil and filter today because the oil that was in there turned into complete sludge. I bought new headlights off of LMCTruck.com but the prongs on the lights don't match the electrical connection on the truck.

its okay about the truck being in the garage... i have learned to deal with it hehe.. and when its all said and done im sure i will be happy with it.. just kinda wished i didnt "TAKE its so far so quick" on the upgrades, oh well lol..

as for lights from LMC which ones did you buy? i see that theres upgraded wiring harnesses for there upgraded lights... might be something to look into...

and as for the oil being sludge i know you just changed it, but you might want to think about changing it next ALOT sooner... say 500 miles or so.. just so you can get more of the nasty outta there.. and probably after that you can go back to normal scheduled maintenence.. depending on how it looks and all...
im going to look for the the window thread next... hope i can help
