When it will not start check to see if it has fuel pressure, the fuel pressure test port is in on the fuel pipe that supplies the fuel injectors. You can rent the tool to check the pressure or borrow it from Autozone.
Not familiar with those cars but guaranteed you have an sir lock in your fuel rail or injectors, look for a bleeder screw on your fuel filter or fuel rail. Can also be bled through fuel line fittings, be careful of high pressure fuel!
If it is a diesel then the cold start injector will be in the manifold . There will be a pipe connected to it and a wire as the injector normally squirts on a hot element which creates a fire that is drawn into the combustion chambers.. Check that the element is operational. If petrol then run the fault codes to find out the problem. I would be having a pressure test done on the fuel manifold to check the pressure regulator and pump operation
Hi there: This Australia made TOYOTA CAMRY SV21 was produced in 1989, similar at 3S-FE Engine...
Disconnect the negative battery cable.
Disconnect the harness from the cold start injector.
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.
Disconnect the vacuum sensing hose from the fuel pressure regulator.
Disconnect the fuel return pipe hose.
Remove the pulsation damper with the two gaskets. Discard the gaskets and purchase new ones.
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.
Remove the four insulators and two spacers from the cylinder head.
Gently pull the injectors from the delivery pipe.
Remove the O-rings and grommets from the injectors and purchase new ones.
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.
Lightly coat the O-rings with clean fuel.
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.
Place the four insulators and two spacers on the cylinder head.
Install the injectors together with the delivery pipe onto the cylinder head.
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.
After the delivery pipe and injectors are properly in place, go to each injector and position the connector so that it is facing upward.
Install the two delivery pipe retaining bolts and tighten them to 9 ft. lbs. (12 Nm).
Install the pulsation damper with two new gaskets on both sides of the fuel hose "banjo'' fitting. Tighten the damper.
Connect the fuel return hose.
Attach the injector connectors.
Connect the vacuum sensing hose.
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).
Attach the cold start injector wiring connector.
Connect the negative battery cable.
Short the +B and Fp terminals of the engine check connector with a jumper wire.
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.
you need to check the fuel pressure, running it should be around 50psi. and after shutting down try to start, fuel pressure should jump to 50 psi within 1-2 seconds. if it has to build up you have fuel bleeding down somewhere. I have run into dirty injectors that are dribling after shut down causing a semi-flooding condition also there is a check valve in the fuel pump which is supposed to hold fuel in the system for the next start.
there is a fuel supply pipe above the fuel injectors on the right of engine as u stand in front of the truck, on that pipe there is a valve that has a plastic cap on it, the valve looks like a metal tire valve, fuel pressure is checked there, you will need a test gauge to screw on the test port, about $15 at any Kragen or Autozone.
