it is under the upper intake manifold, if you have a vortec engine
Under the upper intake assembly
under the intake manifold mounted to the CFI (central fuel injector)
depends on the type of fuel injection on the motor... on the CSEFI injector assembly the regulator is located under the air intake plenum on the back of the fuel meter body. If it's TBI, the fuel pressure regulator is located inside the throttle body.
It is located under the upper intake manifold. It is connected to the bank of fuel injectors (poppets) bank.
It is in the throttle body.
This fuel pressure regulator is a component part of the SFI (sequential fuel injection) assembly, sometimes referred to as "spider". It resides inside of the air intake plenum and is accessed by removing the upper half of the intake.
The oil pressure sensor, on your 2003 Chevrolet engine, is located on the front of the engine, just above the oil pan. The pressure sensor will have two wires going to it.
The regulator is under the plastic upper intake manifold. It is in the end of the injector housing or pod.
Where is the oil sending unit located on the 2001 Chevy 43. vortec engine?
That is were the fuel injectors are at, and the fuel pressure regulator is on the rear of it.
how do u replace fule pressure regulator in 94 blazer vortec
It is located at the top side rear of the engine block and right next to the distributor.
It's integral to the alternator.
Check the pressure regulator, fuel filter and fuel pump.
on the fuel rail. depending if it is throttle body, or a vortec
Need to check fuel pressure regulator, and it could be the MAP sensor making it run rich. Is the check engine light on???? If it is have engine scaned with engine scanner so you can read the codes, and see what is going on with the emissions.
If you Google "Symptoms of a faulty fuel regulator" you will get quite a few hits. If the regulator is bad it may cause either a drop in fuel pressure or an increase in fuel pressure at the rail . A drop in fuel pressure, if severe enough, can cause bad or no idle condition, engine starving for fuel and etc. If the regulator is causing excessive pressure it can cause fouled plugs, black smoke from exhaust and rough engine performance. Before you change the regulator check for cracked, rotted or disconnected vacuum hose. Also you can connect a fuel pressure gauge to the schrader valve on the rail and monitor the pressure to see if it is in specifications, or to see if the fuel pressure drops rapidly after engine shutdown. Hope this helps and good luck with your problem. Dan
Fuel injectors are leaking at shutdown. NEW ANSWER: There is a fuel pressure regulator underneath the upper intake plenum and is located on the rear of the injector housing/ spider unit. They are none to leak fuel into the engine crank case/ OIL. It is a common problem with the vortec engines.
Oil Pressure is not a
Vortex engine? Got me. I thought Vortex was just a brand of supercharger. I believe you mean Vortec engine.. GM also called this the L31 (they use 3 letter/number codes for everything) This system used a SCPI (Sequential Central Port Injection) system... and the fuel pressure regulator is on the central unit, which is INSIDE the intake manifold- you have to remove the upper intake manifold to get at it (plastic part), and the Fuel pressure regulator will be on one side of the central unit where all the fuel lines go to, it has a tube on it open to the intake manifold (to read intake vacuum)
People will need to know if it's a throttle body injection (TBI) or a vortec injection to answer you.
It's at the top rear of the engine near the distributor.
follow the radiator hose to the engine, right where the hose meets the block is where the thermostat is located. Its on the the front of the engine
135 from front to back located on the drivers side or right.246 front to back located passenger or left.
