Injector pipe lay out? - Cars & Trucks

if the injector is held in by 2 bolts through a mount and the pipe is at the injector, remove the nuts , tap the side of the mount back and forth then use a pry bar under the mount and lift out of the hole
f there is a big nut under the injector that holds it in undo that nut and if the injector pipe is in the injector
tap and pry out
If the injector piper goes into the head and not the injector , remove it from the head first as it goes right into the injector body and acts like a grub screww

Usually, the No1 pipe goes to the No1 injector - the injector closest to the front of the engine where the belts are

The injector pipes are pre-bent to the correct positions so offer the pipe up to the pump and injector and if it will not easily then put it on the next injector until it fits exactly.

if the injector pump is an inline pump ( where all the injector pipes are arranged along the top of the pump the no 1 injector is the line closest to the front of the engine . If it is a rotary pump ( where the injector lines mare arranged in a circle at the back of the pump no 1 will be either at the 10 oclock or 2 oclock position. As the injector lines are hard and bent for each piston then the line from no 1 injector will point to the no1 position on the pump regardless of how many cylinders there are. If it is a common rail diesel then it doesn't matter because the injection timing is electronic and set from the crank shaft position sensor.

These are self bleeding so if diesel is getting to the pump it won't need bleeding. If you still feel the need to bleed the system then loosen one injector pipe turn the engine until you see diesel coming tighten again it should fire up. If you have a good flow of diesel coming from the filter to the pump and diesel at the injector pipe then your pump pressure may be low. To check remove any injector reconnect the pipe to it with the injector end where you can see it. Turn the engine with the starter a few times the diesel should be making a mist.

Hi there:
This Australia made TOYOTA CAMRY SV21 was produced in 1989, similar at 3S-FE Engine...

1. Disconnect the negative battery cable.
2. Disconnect the harness from the cold start injector.
3. Place a towel or rag under the cold start injector pipe and remove the two union bolts, four gaskets and delivery pipe.

Loosen the union pipe bolts slowly.

1. Disconnect the vacuum sensing hose from the fuel pressure regulator.
2. Disconnect the fuel return pipe hose.
3. Remove the pulsation damper with the two gaskets. Discard the gaskets and purchase new ones.
4. Unbolt and remove the delivery pipe with the injectors attached.

When removing the delivery pipe, take care not to drop it as damage to the injectors may result.

1. Remove the four insulators and two spacers from the cylinder head.
2. Gently pull the injectors from the delivery pipe.
3. Remove the O-rings and grommets from the injectors and purchase new ones.

To install:

1. Install a new grommet and new O-ring onto each injector. Make sure that they are installed evenly, to ensure a good seat and save yourself from having to take the injectors out and readjust or replace the O-rings.

1. Lightly coat the O-rings with clean fuel.
2. Install the injectors into the delivery pipe. Do not **** the injector, install it straight into the opening using a light left to right twisting motion.
3. Place the four insulators and two spacers on the cylinder head.
4. Install the injectors together with the delivery pipe onto the cylinder head.
5. Go to each injector and rotate it by hand. The injector should rotate smoothly.

If the injectors don't rotate smoothly, the O-rings are probably not installed correctly or the injectors are not installed evenly. If this is the case, you will have the pull the delivery pipe off the intake manifold and look at the O-rings to make sure that they are installed correctly. Adjust the O-rings and, if damaged, replace them.

1. After the delivery pipe and injectors are properly in place, go to each injector and position the connector so that it is facing upward.
2. Install the two delivery pipe retaining bolts and tighten them to 9 ft. lbs. (12 Nm).
3. Install the pulsation damper with two new gaskets on both sides of the fuel hose "banjo'' fitting. Tighten the damper.
4. Connect the fuel return hose.
5. Attach the injector connectors.
6. Connect the vacuum sensing hose.
7. Using new gaskets, connect the cold start injector pipe to the delivery pipe and cold start injector. Tighten the two union bolts to 13 ft. lbs. (17 Nm).
8. Attach the cold start injector wiring connector.
9. Connect the negative battery cable.
10. Short the +B and Fp terminals of the engine check connector with a jumper wire.
11. While the connector is shorted, pinch the fuel return hose. When the pinched, this causes the pressure in the high pressure fuel line to rise to 57 psi. ( kPa) At this time any leaks in any part of the system should be apparent. Carefully look at each component for leakage and run the tip of your finger around each connection.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

REMOVAL & INSTALLATION

1. Disconnect the negative battery cable.
2. Remove the accessory drive belt from the supercharger pulley.
3. Relieve the fuel pressure and remove the fuel injector sight shield.
4. Disconnect the fuel pipes from the fuel rail and vacuum hose at the pressure regulator.
5. Disconnect the electrical connectors from the fuel injectors and remove the fuel rail mounting bolts. Remove the fuel rail with the injectors intact.
6. Disconnect the electrical connectors at the IAC, TPS, MAF, EGR and boost control solenoid. Lay the wiring harness aside.
7. Remove the air intake duct and remove the EGR pipe from the supercharger.
8. Disconnect the throttle cable and the cruise control cable. Remove the cable bracket.
9. Remove the tensioner bracket to supercharger mounting stud.
10. Remove the supercharger to intake manifold bolts, remove the supercharger from the intake manifold. Remove the supercharger gasket and coolant passage O-rings. To install:
    
11. Replace the oil passage O-rings and the supercharger gasket.

air lock ,slacken injector pipes ,crank engine and as fuel starts to appear tighten pipes as fuel appears .make sure you prime the injector pump first .great workhorses these motors

could be the injector washers leaking or leak off pipes but you will have to remove the rocker cover trim for inspection
