How to check ignition coil on a 1994 Nissan Altima. I installed new spark plugs, rotar and cap. Also bought a new control modular and it still won't start. I also checked the fuel pump and it pumps pleanty...


Most parts stores, such as Auto Zone, can give you the specific Ohms values for your coil. You will want to check the resistance between where the coil wire goes to the coil, and the electrical terminals the coil. And compare it with the OEM resistance.

Slipping transmission


It just needs serviced. It could be Loose bands or just need adjustments and a Torque converter needing service. If the fluid level is good when checked then take it to a transmission shop and have it checked. It could be something as simple as a Fluid change and Filter replacement.

Replace a fuel pump on 2000 chevy cavalier


REMOVAL & INSTALLATION
(see Figures 1 and 2)

CAUTION The fuel injection system remains under pressure, even after the engine has been turned OFF. The fuel system pressure must be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.
  1. Relieve the fuel system pressure using the recommended procedure.
  2. Disconnect the negative battery cable.
  3. Drain the fuel tank, then remove the fuel tank from the vehicle.
  4. While holding the modular fuel sender assembly down, remove the snap-ring from the designated slots located on the retainer.

WARNING The modular fuel sender assembly may spring up from its position. When removing the modular fuel sender from the tank, be aware that the reservoir bucket is full of fuel. It must be tipped slightly during removal to avoid damage to the float.
  1. Remove the external fuel strainer.
  2. Detach the Connector Position Assurance (CPA) piece from the electrical connector and detach the fuel pump electrical connector.
  3. Gently release the tabs on the sides of the fuel sender at the cover assembly. Begin by squeezing the sides of the reservoir and releasing the tab opposite the fuel level sensor. Move clockwise to release the second and third tabs in the same manner.
  4. Lift the cover assembly out far enough to detach the fuel pump electrical connection.
  5. Rotate the fuel pump baffle counterclockwise and remove the baffle and pump assembly from the retainer.
  6. Slide the fuel pump outlet out of slot, then remove the fuel pump outlet seal.

To install:
  1. Install the fuel pump outlet seal, then slide the fuel pump outlet in the slots of reservoir cover.
  2. Install the fuel pump and baffle assembly onto the reservoir retainer and rotate clockwise until seated.
  3. Install the lower retainer assembly partially into the reservoir. Line up all 3 sleeve tabs. Press the retainer onto the reservoir making sure all 3 tabs are firmly seated.

Gently pull on the fuel pump reservoir from retainer to assure a secure fastening. If not secure, replace the entire fuel sender.
  1. Attach the fuel pump connector.
  2. Fasten the CPA connector to the fuel sender cover.
  3. Install a new external fuel strainer.
  4. Install the modular fuel sender.
  5. Install the fuel tank in the vehicle.
  6. Connect the negative battery cable.
  7. Pressurize the fuel system and verify no leaks.

have you looked at the air filter? have you done a catalyst efficiency test? this could be a plugged cat. save yourself the time and aggrevation and locate a reputable muffler/exhaust repair facilty and have them check the catalytic convertor. happy holidays

Hello lendor9 and thank you for choosing fixya.com

I suggest making sure the cap and rotor (if distributed) are good. If it has a coil pack and modular, have the coil pack(s) tested - when taking the coil pack(s) off - look at the top of the modular, and look for damage such as bubbles, like it has been boiling - black or white residue - if any of this exit, replace the modular. Also replace any coilpack(s) as needed. Be sure that the wiring harness for the modular is screwed in and secure. Have a diagnostics test done on the car to determine any codes that will reveal THE, or any other problems. You may need to replace the O2 sensor(s), as well as the air and fuel filter.

I hope this information is useful in getting your truck running smoothly again. Thank you again for choosing fixya.com
