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 1999 vortec 4.3l 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





Fuel pressure regulator repair blazer bravada jimmy s10 sonoma 4.3l
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.

The distributor cam sensor retard is re-synced using a scan tool. The re-sync also needs to be performed at times when a P0340 trouble code sets.

Solving Cold Start Problems 1999 GMC Jimmy -EricTheCarGuy
A friend of mine brought me this 1999 GMC Jimmy stating that they were having trouble starting the truck when it got cold outside. Of course the day they brought it to me it wasn't cold. Because of that, I had to look for possible causes of the problem. In this video I cover the basics of what I check in a situation like this. I did find something, be sure to watch the video to see what I found. Here's some useful links for you.

Easy free way to gain a noticeably better throttle response. Does not gain horsepower like companies claim. Please read description. Thanks. The mod is to remove the diffuser / restrictor off the bottom of the blade to increase airflow into the engine. free alternative to a $40 cfm tech blade. Make sure you reset the computer (reset by disconnecting battery) Took me about an hour from start to finish please don't tell me that my front 2 cylinders will lean out. there is no need to restrict the EGR due to this mod.... the truck is a 1999 GMC Sirra RCSB 4.3L Vortec V6 SCPI soon to be MP cat back straights. k&n Filmed with my iPhone.





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.

About the "Fix It Right!" video series: "Fix It Right!" is a series of how-to videos intended to give do-it-yourselfers basic instructions on proper vehicle repair and maintenance. All of our videos show real repairs being performed on real vehicles by real technicians in a real auto shop. (Repairs are filmed and shown with the permission of the vehicles' owners.) Although there may be more than one way to perform any particular repair (and in many cases there are lots of ways!) we try to focus on the methods that will be safest and most expedient for DIYers with limited access to tooling and equipment. We will also occasionally be showing repair processes that are too complex or dangerous for DIY, or require specialized tooling, expertise, equipment, and/or certifications. Those episodes will highlight the importance of hiring a professional auto technician for tasks that are not DIY-friendly, and demonstrate why such tasks are best left to professionals.

GM Troubleshooting Part 5 - Fuel System including filter, pump, injector, regulator
This is part 5 of a multi part video series about how to troubleshoot any ignition, fuel injection or timing issue. I describe the fuel system and what I did to test it. specs referenced in the video: fuel pressure (in PSI): TBI (9-13), MFI (41-47), CMFI (58-64), CSEFI (55-61). Those pressures are for key on, not running. When running normal range is 3-10psi less for all injection systems. Injector resistance (in ohms): TBI 1.16-1.36, MFI (11.6-12.4), CMFI (1.37-1.77). In the video I forgot to mention it is fairly difficult to bend the spider legs of the new injector unit so they fit in the intake holes. Pay attention to the way the original was installed (legs going over/under the nut kit lines) and try to replicate the original routing. Oh... and I forgot to mention that if you have a fuel lean condition, spray quick start in the throttle body and see if it starts... if it runs on quick start, you have proven your condition is a lack of fuel. UPDATE Dec 8_2011: I still have the 2 moulded fuel injector lines (new never used) and I want to sell them... if you need these lines send me a private message and we can work out a deal. Thanks.
