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.

Chev / GMC Misfire, poppet injector diagnosis, troubleshooting and replacement
http://www.wellsve.com/ This video demonstrates how to diagnose a sticky
poppet injector utilizing scan tool and 5 gas techniques. The upper and
lower intake are removed and replaced. 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.

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
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

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 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.

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

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
-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

Secret of Engine Problem Diagnosis- Fuel Trims Pt.1
One of the best techniques for diagnosing check engine lights or engine
problems especially for lean or rich engine diagnostic trouble codes
(DTC's) is to examine and interpret Fuel Trim data. This video will help
the home mechanic learn how to use a very basic scan tool to develop
powerful diagnostic capabilities and prevent changing parts unnecessarily.

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.
