Question about 1990 Acura Integra Hatchback

1 Answer

1990 Acura Integra

I have fuel to engine, battery is at full amperes, starter is new. At 3500 rpm the vehicle was beginning to hesitate in any gear. Shut the vehicle off problem went away. That was 2 days ago. Fired it up this morning and then replaced the thermostat. Now the car wont start. No spark to plugs. Is it possible my ECU has caused a problem for my distributor and I now lost my cap?? Check engine light has been on and is not giving any codes thru the test. How do you really test the engine codes to make sure I am doing it right!

When the Check Engine warning light has been reported on, turn the ignition on, pull down the passenger's side carpet from under the dashboard and observe the LED on the top of the ECU. The LED indicates a system failure code by blinking frequency. The ECU LED can indicate any number of simultaneous component problems by blinking separate codes, one after another. Problem codes 1 through 9 are indicated by individual short blinks. Problem codes 10 through 43 are indicated by a series of long and short blinks. One long blink equals 10 short blinks. Add the long and short blinks together to determine the problem code.

How can i get to the fuel pump on a 92 acura vigor?

  • Print
    The fuel pump on all models except the 1986-90 Integra, is located in the fuel tank. On the 1986-90 Integra the fuel pump is located under the rear of the vehicle, near the drivers side of the fuel tank.


    See Figure 1
    On all models, the fuel pump should run for about 2 seconds when the ignition is first turned ON . By removing the filler cap and listening at the filler, it should be possible to hear the pump run each time the ignition is switched ON . It will then stop again until the starter is activated.

    Fig. Fig. 1: Checking the fuel system pressure

    1. Disconnect the negative battery cable and remove the fuel filler cap.
    2. Relieve the fuel system pressure.
    3. Remove the service bolt and attach a fuel pressure gauge to the top of the fuel filter.
    4. Start the engine and measure the fuel pressure with the engine idling and vacuum hose to the pressure regulator disconnected;

    1986-1989 Integra-35-41 psi. (240-279 kPa) 1990-93 Integra-37-44 psi. (255-304 kPa) 1989-90 Legend-36-41 psi. (250-279 kPa) 1991-93 Legend-38-46 psi. (265-314 kPa) Vigor-43-50 psi. (300-350 kPa)
    1. Check to see that the pressure decreases when the vacuum hose is connected.
    2. If the pressure is higher than specifications, check for a pinched or clogged fuel return hose or faulty pressure regulator.
    3. If the pressure is lower than specifications, check for a clogged filter, defective pressure regulator or leakage in the fuel line.
    4. After inspection, remove the pressure gauge and install the service bolt with a new washer.


    1986-1989 Integra

    1. Disconnect the negative battery cable.
    2. Relieve the fuel system pressure.
    3. Raise and safely support the vehicle and remove the left rear wheel.
    4. Remove the fuel pump cover bolts and the cover.
    5. Remove the fuel pump mount bolts and the fuel pump with it's mount.
    6. Disconnect the fuel hoses and the electrical connectors.
    7. Installation is the reverse of removal. Use new sealing washers when connecting the fuel hoses. After the pump is installed, turn the ignition switch ON and OFF a number of times to pressurize the system and check for leaks.

    1990-93 Integra and Vigor
    See Figures 2 and 3
    1. On Integra, remove the rear seat and access panel and disconnect the wiring.
    2. Remove the fuel tank.
    3. Remove the pump flange mounting nuts and lift the pump out.
    4. Installation is the reverse of removal. Use new sealing washers when connecting the fuel hoses. After the pump is installed, turn the ignition switch ON and OFF a number of times to pressurize the system and check for leaks.

    Aloha, my 96 integra starts up just fine idles at around 1500 rpm as it is warming up than after warmung up begins to have a low idle of 500 to 600 rpm sometimes lower. occassionally even if the gauge...

    I don't know if you did this already, but, you didn't mention a new air filter. A dirty air filter prevents the engine from getting the proper mix between air and fuel that it needs to run smoothly. Very often a new air filter resolves many of the issues you're having.

    I hope this helps you.

    Why won't my 1990 acura integra go over 4000 rpm?

    Could be fuel filter. This will restrict a lot. If it is automatic it might be your transmission control module. Your check engine light should be coming on if it's not already.

    My 1995 Acura Integra starts running roughly at 3500 rpms. Kept below 3500 rpms, it runs fine with no problems. It just started doing this. Never before. It seems there is somekind of govenor that kicks in...

    If the fuel filter hasn't been changed in the last 2 years, that is a good place to start. Also,have you given it a full tune-up recently? those are the easy suggestions. Typically the major stuff shows up with a "check engine light" indication. My '97 Civic acted similarly to this, and it ended up being the fuel filter(at 167,00 miles). Cap/rotor/plugs or other ignition system faults will also limit high rev performance. When in doubt, Autozone will check your computer system for no charge if you're concerned about sending good money after bad.

    Acura integra 1990 turns over fine but doesnt start

    for you to check if it is the fuel pump, see if there is fuel running out of the hose if you remove the fuel filter. Another is to directly connect the pump to the battery. If the pump works that way, then it could be a efi relay issue which is found underneath the dash or a wiring issue.

    1990 acura integra - was driving car and all the sudden the engine quit and RPM's dropped. have plenty of gas, what are the possibilities/problem. Car will now not start

    depends. First check for fuel and spark. Its rare a honda pump go out but it does happen. It has happened to me a couple times. Ive owned 14 hondas so this should be accurate. The ignition control module is located in the distributor, its a small square black piece that has four wires pluged onto it. Have that checked and also the coil. We'll go from there for now
