No injector relay in this car. Injector pulse is controlled directly from ECU.

SOURCE: 94 Celica GT, Fuel Problem?

The computer is what outputs that. So you want to check the wire at the computer and see what your getting. Has the motor been pressure washed or have any changes been done recently?
Thanks,

SOURCE: injectors not getting electrical power and not releasing fuel into the cylinders, hence no engine start

All pre 2008 powerstrokes use oil pressure supplied by a High Pressure Oil Pump(HPOP)to activate a plunger setup in the injector to inject fuel into the cylinders at 21 PSI. More than likely some of the HPOP components need to be replaced- i.e. valve, regulator, seal, feed tube...or the pump itself. I've replaced seals on these units since 2003, when Ford wanted to replace the pump and injectors. Did you notice a gradual increase in hard starting conditions? Do you have any visable oil leaks? Did you run the crankcase oil level down to below the add mark recently? All of these could be a factor. Ford wont tell you anything about a price because they dont like to do that before they do a diagnostic check on it and determine exactly how much needs to be fixed. Test alone will run around 100 buxs. If you are within warranty requisites then it wont matter and you likely wont be charged anything. If they crack into it have em fix as much as you can while theyre in there, because after warranty is out you are looking at a 3000 dollar repair bill from your friendly Ford dealer. Good luck...i hope this helps.

SOURCE: no power to fuel injectors or fuel pump

sometimes the relays can be found underneath the carpets or plastic panels under the dash. have you checked the fuses?

SOURCE: Volvo 240 2.3L FI the engine has spark, no injector pluse.

Pull the return fuel line off the back of the fuel pressure regulator and plugit.
attach another hose and clamp it to the back of thefp regulator place the othe end in a container.
pull the coil wire and have someone crank the engine or use a remote starter switch.there should be a steady stream of fuel into the container. If not check your intank pump and main body pumps for electrical connections.
If there is a steady stream from the fuel rail and still no gas at the plugs.
Find another fuel injector for a volvo,unplug the # 1 injector electrical connnection and plug in the extra one placing it in a container and crank the engine over. There s/b an even spray of fuel from injector.
If not check for 12 volts at the injector connectrion. If no volts,check backwards to the ballast resistor which controls the injectors and then to the radio suppression relay etc.

What make , model an year vehicle ? Could be a relay problem , power hold relay for ford , ignition 1 relay for GM vehicles or ASD - auto shut down relay for jeep , dodge , Chrysler vehicles . Asian vehicles have them too , Honda - main relay powers fuel injectors , coils etc.... Do you know how to do basic automotive electrical testing ? Check for voltage ? You would need to look at a wiring diagram for your vehicle , see which wire powers the coil an injectors etc...test for B+ voltage ! Videos on you tube showing how to test ignition , fuel etc..

Can all three injectors on one side go bad at the same time


Not usually. They use the same power source but are grounded at different times by the engine computer.
Its possible one bad injector could damage the others, but that rarely happens.
An injector is an electric valve with a small coil and magnet inside.

Bad fuel pump or relay to fuel pump or blown fuse to Main Relay or bad relay, could cause no spray from injectors.

Can anybody tell me how to change fuel injectors on 1989 audi 200 quattro?


first relief fuel pressure before disconnecting fuel lines remove fuel pump fuse or relay start engine let it idle until stall out lack fuel fuel now fuel pressure is reliefed. you have to remove top upper air cleaner housing, you have to remove whole entire air cleaning system because the fuel lines with fuel injectors is under the air cleaner filament you have to remove entire fuel line with fuel injector in order to replace fuel injector.

How do you install injectors in a chevy s-10 pick-up?


Removal & Installation

8205896.gif
Exploded view of the fuel rail and injector mounting


Take care when servicing the fuel rail assembly to prevent dirt or contaminants from entering the fuel system. ALL openings in the fuel lines and passages should be capped or plugged while disconnected.
  1. Before disassembly, clean the fuel rail assembly with a spray type cleaner such as AC Delco® X-30A, or equivalent. After removal, DO NOT immerse the fuel rail in liquid solvent.
  2. Properly relieve the fuel system pressure and disconnect the negative battery cable.
  3. Remove the air intake duct, as necessary for access.
  4. Tag and disengage the fuel injector electrical connectors.
  5. Disengage the fuel pressure regulator vacuum line, then tag and disengage all other necessary vacuum hoses.
  6. Loosen and remove the fuel rail retaining bolts.
  7. If necessary to remove the fuel rail assembly completely from the engine compartment, or to prevent stressing and damaging the fuel lines, disconnect the fuel lines from the rail assembly.
  8. Carefully lift the fuel rail assembly and fuel injectors from the intake.
  9. Carefully release and separate the fuel injectors from the rail assembly.
  10. Remove and discard ALL old O-rings from the fuel injectors and, if disconnected, the fuel lines.
To install:
  1. Lightly coat the new O-rings with clean engine oil, then position them to the injectors and, if applicable, fuel fittings.
  2. Install the injectors to the fuel rail assembly.
  3. Carefully install the fuel rail and injectors to the intake manifold. Make sure the injectors are properly seated in their bores, but DO NOT force them into position.
  4. Install and tighten the rail retaining bolts to 62 inch lbs. (7 Nm).
  5. If removed, connect the fuel lines to the rail assembly and secure the fittings.
  6. Engage the fuel pressure regulator and any other vacuum lines, as noted during removal.
  7. Engage the injector electrical connectors.
  8. Connect the negative battery cable and cycle the ignition switch (without attempting to start the engine) in order to pressurize the fuel system, then check for leaks.
  9. Install the air intake duct.
