    Ignition problems, need some advice.

    Hey guys. It's been a loooong time since I've been on the site, but I've run out of ideas and I'm sure someone here will be able to help me. A little back story, my ignition went out like two years ago. Never could figure out why. Turn the key, nothing. No starter click, just dead. The lights...

    Carbureted guys, get in here! (Need some advice).

    I've decided to go with a carb swap, boys. Can someone help me with a list of parts? So far I've thought of: -Edelbrock 600cfm four-barrel (I think that should be plenty for my motor) -fuel pressure regulator since I'm running a TPI pump -fuel lines -HEI distributor -700r4 linkage for the...

    What have YOU done to your motor?

    From mild to wild, let's hear it! I'll start. On the '92, BEFORE blown head gasket. -Roller cam conversion, stock/mild cam (don't have specs). -Cylinder walls bored .030" over, stock-style flat top pistons. AFTER the top-end rebuild/head gasket replacement. -2000 year-model Vortec L31...

    Fan blower never turns off?

    Hey guys. Ever since i got my truck, my A/C never worked. I think the low pressure switch is bad, because the A/C blows ice cold when i jump the connector. Here's my problem, though. The fan NEVER turns off. Literally. It's always blowing through the vents under the dash, even when the HVAC...

    Anyone ever have a bad/stretched timing chain?

    Has anyone ever had a timing chain lose tension or stretch? As far as I know, the motor has about 110,xxx miles on it since the rebuild, when the chain was allegedly replaced. Can someone explain what happens when one stretches or jumps a tooth? My truck bogs down BAD under even the...

    Excessive load on alternator?

    Hey guys. Just curious, I've heard people say that we shouldn't trust the gauge on the dash, but does anyone else have it dip pretty low sometimes? For example, with my headlights on (35w HIDs on their own relay harness), and the radio loud, it'll dip a few lines under 14 (like 12-13 or so) and...

    Swapable alternators?

    Do you guys know if there are any higher amp stock GM alternators that will bolt in place of my 105 amp? I feel like it's not enough for my truck, since I run a lot of lighting (LEDs, but still), and have a few auxiliary harnesses connected to my battery. I wanted to see if I could find an NBS...

    My documented TBI-to-Vortec 350 conversion!

    Hey guys! As some of you may know, I recently had to rip apart my motor due to blowing a head and/or headgasket. I was originally going to have the heads cleaned and rebuilt, and throw some new gaskets on her, but then I got to thinking that this would be a perfect time to pick up some Vortec...

    Flowmaster Super 10 driving video!

    Because quite a few of you asked, decided to make a quick video before work. As of right now, It's louder than I'd like, because it sits like this: But I'll soon have full piping run all the way out back to quiet it down a bit. Anywho, the video has alot of wind and tire noise, but it's...

    Summit Y-Pipe fitment/quality?

    Hey guys, just curious, does anyone have any experience with the Summit Racing y-pipes? Do they bolt right on and fit with the stock headers? I am doing a full exhaust one piece at a time. And are these even worth messing with, like better than stock at all? The stock y-pipe looks pretty...

    idle problem. Vacuum? MAP sensor? Brake Booster?

    On my phone, sorry for any spelling/ grammar errors! Basically, the truck idles like crap! Sounds like it's missing, popping out of the exhaust, and sometimes even dies when putting it in gear. Something VERY weird happened last night that made me think it's vacuum related. I was sitting...

    I kinda wanna buy it...('94 Sierra)

    I know it's probably in WAY worse condition they described, but I've really been wanting a 4x4 ECSB. http://mcallen.en.craigslist.org/cto/3830296285.html

    My review of Xentec eBay HIDs!

    Hey guys, I know one of the hot topic on this forum is what brand of HIDs to buy. There isn't much info on Xentecs, at least that I have seen, so I figured I'd post up my experience. I ordered a 35w 5000k (their whitest) low-beam kit with a cheap eBay wiring harness with the intention to install...

    Trying to diagnose a miss/tick/knock.

    Its a loud noise at idle. Sounds exactly like when two bolts had come off the passenger side exhaust flange, but more severe. Also, I just discovered the compression on the pass. side is 160 versus the 175 on the driver side. Makes me winder of I blew out the exhaust donut, or if I maybe have...

    Just a PSA to all my fellow TBI owners.

    Some of you guys may have seen my recent thread in which my truck had a few problems all at once. I fixed most of them today. It was idling like crap and would hesitate pretty bad off of red lights/stop signs, etc. So today I decided to rip off the TBI and check some stuff. HOLY BUILDUP...

    What kind of injectors do I have? (TBI)

    Swapped in some injectors that I pulled off my brother's '91 OOBS Suburban, not sure what kind they are. The motor is a 350 just like mine but the injectors look different. They are silver instead of bronze and on the bottom where the screen slides on, there is 4 openings instead of three like...

    What cam should I go with?

    Hey guys, a bit long of a read, lots of info. Some of you might have me on the Fecesbook and have seen that I have plans to build a motor for the truck in a few years. My plan is to give my little sister my truck to use in high school, BUT, that's not for another two years, and my motor...

    I'm out of ideas, guys. (Truck runs like crap no matter what I do).

    Hey guys, if i start unplugging sensors while the engine is on, shouldn't that noticeably change the way it's running? I tried: -Unplugging the o2 sensor (on the driver side header): No change -Unplugging the IAC (which i also just soaked in cleaner): No change -Taking the vacuum line off...

    [HOW-TO] "4-HI" brake light mod (EASY method!) (STOCK TAILS)

    Hey guys! As all of you know, our trucks only light up the middle bulbs in the circuit boards for the brake lights and turn signals. This could cause potentially dangerous situations (bulb goes out, no turn signal), and should have been fixed by GM. Also, some of you may have seen the other...

    [INFO] Bulb numbers for 88-94 LED conversions.

    When i was doing research for bulb numbers and such for my LED conversion, I found TONS of info for the 95-98 interior/trucks, but no consistent/useful info for the 88-94's like mine. Here is what I've gathered (and successfully tested) so far. For future reference, pay attention to the...

    Truck completely dying at WOT and kicking back on afterwards???

    Hey guys, the past few weeks I've been having a VERY annoying problem. When i hit the gas hard (say to pass someone, or get up to a high speed limit), the truck will sometimes COMPLETELY shut off, then as soon as i let off the gas pedal, starts right back up. Recently i rebuilt the throttle...

    700R4 tailshaft housing and seals replacement help.

    Sorry for multiple threads, but i think i have it figured out. Some of you may remember my other thread about a violent shaking coming from my trans. I think i figured it out. A few months ago, i replaced my front U-Joint, thinking it was causing the vibration and play up near the tailshaft...

    Help me diagnose a 700R4 problem? (BAD vibration).

    I have a VERY bad shudder at around 45mph. Apparently, this is when the TC is supposed to lock. I don't know when it started, or what might have caused it, but it was just kinda THERE one day a few months ago. When i tap the gas pedal a bit or let off a bit, the shudder stops. Someone suggested...
