It depends on what kind of engine you have. If you engine has the big black plastic piece on the top center of the engine, then it is located under that plastic piece. If it does not have the plastic piece, then it is located inside the throttle body. I hope this helps you. Please leave good feedback.

There is no carb on a fuel injected vehicle,like for the
last 25 years or more

Have you checked for fuel pressure at motor with a gauge?

Have you checked fuel trim with a scan tool?

I suspect you will have to remove the top of the intake & replace
a leaking fuel pressure regulator

Google your engine & all the problems with injector spyder problems

You can go to YOU TUBE VIDEO & watch Wayne at Real Fixes Real Fast on that issue

Fuel pressure sensor location


Hi,
I think your after the fuel pressure check valve or regulator. This model doesn't actually have a fuel pressure sensor.
The regulator is on the centre of the manifold at the end of the fuel rail. The check valve is right next to the PVC valve which is also at the centre of the inlet manifold.
Let me know if you need more information.
Thanks

In a 92 GMC Jimmy, Where is the Fuel Pressure regulator?


If this is the 4.3 liter the fuel pressure regulator is located in the intake valley. You will need to remove the upper half of the intake manifold, once removed you will see a small round regulator located at on end of the injector line.

I have fuel in the oil


Sounds like a top end repair of seals or a piston ring issue, or the intake manifold gaskets are leaking. With the age of the vehicle you may be able to go with the intake gasket first but if its the heads then you have to do it twice, and if its the rings allowing blow by you would have to take the heads off anyway. Just be careful so you get it narrowed down quick and easy check compression to see about blowby and the head may help.

Fuel pressure regulator


How do you know that it is the regulator?
these 4.3 motors had a lot of trouble from 93 to 98, I know I had 2 of them.
What happened to mine was that the intake kept getting very carboned up. After I would clean it, the truck would run fine for about 5 or 6 months, then same thing.
Theres actually a class action lawsuit about this that I believe has been settled, you may have recourse if you bought it through a dealer. Good luck.You'll need it.

1994 jimmy fuel shutown @spider?


Hi

A very common failure on these is the CPFI unit , or SPIDER as people like to call it.

There is one single injector which feeds each cylinder via a pipe and poppet. The injector becomes blocked and the engine won't start or run.

Before you go condemning this though, just make sure you have good fuel pressure because the fuel pressure regulator or fuel pump could also have a hand in the problem. Make sure the pump is running, and if not then check the fuse, the relay, and the pump itself.

Very best regards
