How To Replace The Fuel Spider/Fuel Pressure Regulator on a GM 4.3/5.7 V6/V8

I replace the fuel spider in my 1999 GMC Sierra 4.3 liter V6. The fuel spider also includes the fuel pressure regulator, which is another common point of failure. If you have any questions just post a comment and I'll try to help. If you find the video helpful please remember to like/favorite it!

GM 4.3L V6 / 5.7L V8 - Fuel Spider Swap, SCPI to MPFI
Video of me swapping the fuel spider out of my vortec after it failed. All the tools and tricks needed for the job are outlined in the video. 5/8'' Crows foot will be your best friend. here were the symptoms: Truck would start rough and require throttle to even out when warm. Would usually cold start fine. This lasted for about 6 months, then it got to where it would be so flooded it would run like shit and not even out. fuel pressure regulator was dumping fuel out of itself and into the upper intake; whenever the fuel pump turned off. I demonstrated this in the video with the plenum off and the injectors plugged in. please subscribe to help keep my channel growing If your have a pre-2003 4.3L I highly recommend you replace your poppets with the new multi port spider. Just about the best upgrade you could do. Changed the plugs and wires as well and now get 19mpg (up from 16 with the poppets). this video was a nightmare to edit (filmed back in august) and the audio from the camera doesn't sound right royalty free music tecknoaxe i think is how you spell his name......





Leaking Fuel Pressure Regulator
Here is how to know if the fuel pressure regulator is leaking on a 4.3





Fix It Right! - Fuel Injection System Replacement
Fix It Right! - Fuel Injection System Replacement (S1E6) Demonstrated on a 1999 Chevrolet Blazer 4.3L V6 Vortec 2WD. In this video, we demonstrate the process of removing the stock fuel injection assembly, and install an upgraded assembly that converts the vehicle to full multiport fuel injection. This is a fairly straightforward repair to resolve a common issue with the older CFI and "upgraded" CSFI systems used on GM's Vortec engines: sticking poppet valves that dump raw fuel. The stock fuel injection system for 4.3L V6 and 5.7L V8 GM Vortec engines consists of a central injector housing containing either a sequencer (for the older CFI design) or six injector solenoids (for the newer CSFI redesign) and six tubes with a poppet valve on each tube end, each of which are inserted into the intake manifold. The poppet valves are subject to clogging from microscopic debris in the fuel, varnish buildup, etc. Once one or more of them clog, the engine starts to run rough and mileage starts to nosedive. Since the engine control computer will detect a rich condition due to excess fuel consumption and will begin leaning out the engine to compensate, watch for long fuel trims moving strongly negative if checking the vehicle with a scanner capable of reading OBD-II datastreams. The replacement fuel injection assembly is a new design, and instead of using poppet valves and a single injector and sequencer manifold or central bank of injectors, the new assembly replaces each poppet valve with a miniature injector on each tube end. This design has a number of advantages: improved throttle response since there's no transit time for pressurized fuel to travel down the individual injector lines, improved fuel economy (not the least of which is from not constantly dripping fuel), increased horsepower due to improved fuel delivery efficiency, and increased reliability since the injectors have a more forceful open/close action. Generally speaking, customers that have had this procedure performed had positive opinions on their vehicle's post-repair performance.

DIY Fuel Injector Cleaning & Repair
This is the end result of a few hours of work and $60 because I didn't have a 1/4" NPT tap in any of my kits. I could have done this for less-than $40. The BG products were donated to the cause. Tech info: The REASON you want to use 20 PSI is precisely because of how peak-hold type injectors work. The injector signal sends a 4v spike to open a peak-hold type injector quickly, then maintains its open condition with only 1 volt. Really, it's a current thing and there's a longer explanation, but that's it in a nutshell. When you put the injector in its operating pressure, it takes more than a AA battery to open it, but you don't want to sustain that much current with a momentary switch and your expensive injectors. This isn't in the video because this warning wouldn't be as clear. Unless you can simulate the injector pulse precisely, don't try it. 1.5v is enough to open it below its operating pressure. If you open it and THEN apply pressure, you can flow as much pressure as you can throw at it. I don't discourage anyone from getting their injectors professionally cleaned and balanced, but in my case, I didn't feel that was necessary. In my first video, I thanked the seller for these injectors and happy to know I got a great deal on high quality parts. My gratitude is even greater because I had problems with them. It gave me an opportunity to help others troubleshoot these kinds of problems when purchasing used parts. A different idiot might have blamed the seller for peddling crap, demanding their money back... but that would only be because they didn't even know what they were looking at. This particular idiot knows what high quality parts RC injectors are and how to clean 'em. $250 + $60 still means I saved about $150 on a brand new set. We all benefit because I bought these and I'm grateful! Let the good times roll.

if the fuel pressure regulater is leaking in yours replace it, change the oil right after. if it was leaking bad then there will be gas in the crankcase oil. and WILL cause rod bearing failure if not caught in time. over time the gas will leak down the intake passages and into the combustion chamber leaking past the piston rings then into the oil.

Change a Fuel Pressure Regulator
This is a how to video on how to change a fuel pressure regulator on a 96 LT1 Corvette. This is a similar process for almost all cars. This will be identical to all LT1s and LT4s. This will take 30min max and you will need: -small flat head screw driver -5/16 ratchet or wrench (for battery terminal) -various sized star torx wrenches Steps: -spray the torx bolts with "liquid wrench" or some other nut remover to make it easier to remove the bolts. -start by disconnecting the negative battery terminal. -relieve fuel pressure with a fuel pressure gauge or carefully push a screw driver in the fuel pressure valve. - Unscrew and remove the torx bolt that holds the fuel lines down. (the fuel line that goes to the FPR should be loose now) -Unscrew the torx bolt that holds down the fuel pressure regulator (it screws into the fuel rail). -Have a plastic container under the FPR so that excess fuel can fall into it and not on your engine. -Remove the fuel pressure regulator from the fuel rail -Unclip the fuel line from the FPR and now it should be completely removed -Add motor oil to the o-rings that are on the FPR -Attach the new FPR to the fuel rail first -Attach the FPR to the fuel line and reset the clip - Screw down the fuel line torx bolt -make sure you let the area air out so there are no fumes then attach the negative battery terminal -start the engine and check for leaks You are done! a $300 Job done for $50 My Facebook: https://www.facebook.com/chrisfix8 My Twitter: https://twitter.com/ChrisFix6 96, 95, 94, 93, 92, 91, lt1, lt4, corvette, c4, Chevrolet Corvette (C4), Chevrolet Corvette (C6), how to, change, fuel, pressure, fpr, fuel pressure, how, diy, do it yourself, corvette fpr, fuel pressure, fuel injectors, chris fix, chrisfix, Fuel Injection (Profession), Power, restore lost power, corvette gas, corvette race fuel, fuel, gas leak, gas tank, fuel pump, fuel pressure, fuel pressure regulator, fpr, Chevrolet Corvette (Automobile Model), c5 corvette, c5, c3, c3 corvette, fuel pressure regulator, ecm fuel, bulletproof 6.0 powerstroke, 1988 s10 blazer, adjustable regulator, chevy cavaleir, e30 supercharged, b16 itr head, 4.3 vortec turbo, fuel presion valve, celica fuel pressure, fuel pressure, cavalier turbo kit, camry 1998, fuel pump noise, Exhaust leak symptoms, 01 suburu fuel, fuel filter saturn, air control solenoid, bbk fuel pressure, 96 fuelpressure regulater, fuel pre, bad fuel pump, fuel filter testing, check fuel pressure Disclaimer: Due to factors beyond the control of ChrisFix, it cannot guarantee against unauthorized modifications of this information, or improper use of this information.

How To Clean The EGR Valve On A GMC Safari Vortec V6 Engine
Here is how to clean the EGR (Exhaust gas recirculation) valve on a GMC Safari Vortec V6 engine. If your engine started running really rough all of a sudden, your EGR valve may be stuck open. It's easy to remove and clean up. It is a good idea to install an EGR valve gasket with a filter in it to prevent future carbon buildup. Here is a link to a video I made showing the gasket: http://youtu.be/cBUds9Nypmc
