Have you checked the fuel pressure? If it is high and fuel is not returning, the regulator is bad. If it is low and fuel is not returning, the pump is bad.

  • P0335 is a Crankshaft sensor which is located behind the crank pulley a bit and down. Pull the connector and replace it. This basally helps the computer to direct the firing based on the positions of the pistons. Of course you want to check the connections on this and make sure it looks good before replacing it.

  • The P0135 is the bank 1 sensor 1 Oxygen Sensor. They don't work right until they reach somewhere around 600 degrees and if they don't reach that temperature they don't function. Then your fuel/air ratios is off. Bank 1 Sensor 1 is the first sensor running off the exhaust on the same side as cylinder 1.

  • The 3.0 1996 Honda firing order is indicated by the diagram I uploaded below.

ironfist109_70.gif

  • Based on the diagram the first Oxygen Sensor off cylinder 1 needs to possibly be replaced. Check to make sure the connections are nice and tight and not corroded.

  • After replacing an engine I always like to put new sensors in (like the Crankshaft Position Sensor) while it is sitting in front of me to avoid the getting to them after installation.


  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

00Linc ls v8 location of fuel pressure valve need to .ck fuel pressure


I have no experience of your model but the fuel pressure regulator is generally fitted to the fuel rail or in some cases close to the rail. Later cars tend to have the pressure regulator integrated into the fuel rail.
The valve regulates the fuel working pressure and sends surplus fuel into the fuel return line. This helps to cool the injectors and reduce vapour locks. Mostly the regulator also increases the working pressure during acceleration in order to richen the air/fuel mixture and it does this by monitoring the intake manifold depression via a vacuum line.

My hilux 1kd-ftv wont start 3.0 d4d return fuel line full pressure


if it is a common rail diesel then the pressure in the return line would burst it as the line is not capable of 25.000 psi
so the return line will have low pressure if it is blocked some where

have the injectors tested as there may be a tip seat problem that prevents it from starting and the compression pressure is making the pressure in the return line past the needle

Fuel pressure 1998 jeep grand cherokee 4.0 L V6


You should have a test port on the Fuel Supply rail, use a tool from a local auto parts "Tool Loaner program" where you can borrow tools for free,w/a deposit of course,then follow the steps provided;

MPI Fuel System Pressure Test

The MPI fuel system used in vehicles equipped with a 4.OL engine employs a vacuum balanced pressure regulator. Fuel pressure should be approximately 55-69 kPa (8-10 psi) lower with the vacuum line attached to the regulator than with the vacuum line disconnected. System fuel should be 214 kPa (31 psi) with the vacuum line connected to the regulator and 269 kPa (39 psi) with the vacuum line disconnected. CAUTION: Some fuel may be discharged when connecting fuel gauge to fuel rail.
  1. Connect a 0-414 kPa (0-60 psi) fuel pressure gauge to test port pressure fitting on fuel rail (Fig. 7).
  2. Remove vacuum line from pressure regulator.
  3. Start the vehicle.
  4. Note gauge reading. With vacuum line disconnected, fuel pressure should be approximately 269 kPa (39 psi).
  5. Connect vacuum line to pressure regulator. Note gauge reading. Fuel pressure should be approximately 214 kPa (31 psi).
  6. If fuel pressure is not approximately 55-69 kPa (8-10 psi) higher with vacuum line removed from regulator, inspect pressure regulator vacuum line for leaks, kinks or blockage. CAUTION: Fuel pressure will rise to as much as 655 kPa (95 psi) when the fuel return tine is pinched shut, shut engine down immediately after pinching oft fuel return line.
  7. If fuel pressure is low, momentarily pinch shut the hose section of the fuel return line. If fuel pressure remains low, inspect the fuel supply line, fuel filter, and fuel rail inlet for blockage. If fuel pressure rises replace fuel pressure regulator.
  8. If fuel pressure is above specifications, inspect the fuel return line for kinks and blockage.

Capacity Test

  1. Remove the cap from the pressure test port in the fuel rail.
  2. Connect a 0-414 kPa (0-60 psi) fuel pressure gauge to the pressure fitting on the fuel rail (Fig. 7).
  3. Start the vehicle. Pressure should be approxi- mately 214 kPa (31 psi) with the vacuum hose connected to the pressure regulator and 269 kPa (39 psi) with the vacuum hose removed from the pressure regulator.
  4. If the pressure is not to specification, check the following before replacing the fuel pressure regulator:
  • 4a - Inspect the fuel supply and return lines/hoses for kinks or restricting bends
  • 4b - Check the fuel pump flow rate. A good fuel pump will deliver at least 1 liter of fuel per minute with the fuel return line pinched off. If the fuel pump does not pump adequately, then inspect the fuel system for a plugged fuel filter or fuel pump inlet filter (sock). Fuel pump flow rate can be done by connecting one end of an old A/C gauge hose to the fuel test port on the fuel rail and inserting the other end of the hose into a container of at least 1 liter capacity. Run the fuel pump by installing a jumper wire into diagnostic connector terminals D1-5 and D1-6. Be sure to pinch off the fuel return line or most of the fuel will be returned to the fuel tank.

WILL NOT HOLD FUELPRESSURE AFTER ENGINE STOP


Well the most common causes are leaking injectors, fuel pressure regulator, or the check valve in the fuel pump.
You could block off the return line to eliminate the valve in the pump.

How do you bleed the air out of the fuel lines


You should not have to do that on your vehicle.It has a return line to the fuel tank.All you need to do is cycle the fuel pump a few times.Just turn your key on wait a few seconds turn it off turn it back on wait a few and so forth.It should build up fuel pressure and start up.

Location of ac low pressure port location 2004 chevorlet avalanch


Look back on the firewall for the two a/c lines. One is large and on is much smaller. The larger line is the low pressure line. Follow that line back to the compressor. The low pressure port will be on that line.

Sounds like a ruptured diaphram in the fuel pressure regulator. Fuel is being sucked into the motor through the vacuum line. remove vacuum line off regulator and see if there is fuel, or odor of fuel in the line , if so , the regulator is bad. Good Luck

Where is the fuel filter located on a 2002 Lincoln LS, V8 and how do you reduce the pressure on the fuel line in order to safely remove and replace fuel filter.


To relive the fuel pressure look under hood on drivers side front of engine locate the fuel line where it goes into the fuel rail,trace it back a little ways and you will see a schrader valve for checking fuel pressure. Remove the plastic cap and take something like a small screw driver and press the pin in center to release pressure.
To replace fuel filter you have to remove left front wheel and inner plastic fender panel and fuel filter is located behind this at the back area.
