Tip & How-To about Toyota Celica

Engine turns over but wont start

Check for spark.
Remove one spark plug lead from plug. Place a new spark plug into the boot. Ground the tip to chassis. Have a 2nd person turn over car. You should see a bright blue spark with an audible snap. No spark? Orange, weak spark? Check cable integrity, check primary and secondary coil resistance, check ground leads. Check for +12V from primary coil (+) to chassis with key to 'on'. Check condition of rotor cap and rotor button if installed. Cracked rotor caps allow moisture in and spark short-circuits before going to plug.

Check fuel delivery.
Clogged fuel filters, failed fuel pumps or pressure regulators cause a no-start condition. Spray starting fluid into intake. Make sure you use the kind that contains cylinder lubricant. If vehicle starts and runs while you spray, and quits when you stop, then your fuel delivery system is not doing it's job. Isolate problem by checking for pressure at the fuel rail, and then on the incoming side of the filter. If fuel pump does not put out pressure, check to see if it runs at all. Modern electric fuel pumps are often located in the fuel tank and access is sometimes available via a panel under the rear seat (of cars)

Check timing.
Intake and exhaust valves are mechanically actuated on most vehicles by means of a camshaft gear/sprocket (or two) , a belt or chain, and a crankshaft gear/sprocket. The distributors are linked with the camshaft via worm gear or a simple direct drive spline. Mechanical timing is checked via marks (dots) on the faces of the camshaft and crankshaft sprocket. Electrical timing is set with #1 piston at top-dead center of the compression stroke. Set in the distributor so that the rotor button aligns with the #1 of the metal post set in the cap.

Vacuum lines
Often after a top end job has been done such as a head gasket job, vacuum lines were not marked, or markings became unreadable. The vacuum line for the EGR is especially important as improper hook up will cause the egr to stick open during cranking, making it impossible to start. Under most hoods is a diagram showing the vacuum line routing.


Valve clearance.
Intake and exhaust valves must be adjusted with the specified gaps. If an intake valve has no clearance at top dead center of that cylinder, then compression is not made.

i want to change my own spark plug's


Instructions
    • Locate the spark plug cables along the top or the sides of the engine, depending on CR-V model. Once the engine cools, use the trim panel tool to twist the spark plug wire at the wire's boot, which is the larger rubber portion located on top of the spark plug.
    • 2Pull back on the spark plug wire to remove it from the spark plug.

    • Place the socket on top of the spark plug and turn it counter-clockwise to unscrew and remove the spark plug from the well.
    • 4Rub anti-seize lubricant onto the new spark plug threads and on the tip of the spark plug.
    • 5Insert the new spark plug into the well. Manually turn the plug clockwise to thread the spark plug into place.
    • 6Test the tension on the plug with the tension testing tool. Adjust the tension as needed. Honda CR-V spark plugs generally need a tension between 10 and 15 foot pounds. The spark plug's packaging indicates its suggested tension.
    • 7Replace the spark plug wire, turn it from side to side and lock it into place. Continue the process with the rest of the spark plugs one at a time until all of the spark plugs are replaced.

wont start.


If it will turn over check to see if its fuel or fire. To check for fuel, spray quick start for a few seconds into intake. If it starts and stops. its fuel. Change fuel filter and check fuel pump. If it does not start its fire, Could be distributor cap, rotor, coil, spark plug wires or spark plugs. If it does not turn over it could be battery or starter. Check battrey connections, ground strap from motor to body and ground wire from battery to motor and body.

bmw 330ci 2002 not starting


fuel pump, first thing to look at. it's electric, disconnect a fuel line, crank, no fuel coming out, replace the breakable bosch electric fuel pump.
2nd thing, spark, remove spark plug, ground it to the chassis, crank, if you don't see or feel a spark, it could be a number of things, coil pack, or computer that generates the spark.
Crank Sensor, 3rd thing. just replace it.
After that......could be anything, bad head, bad computer, all things you'll want the dealer to check out. the above 3 things....you can do

how do you remove the ignition coil


Each ignition control module (ICM) has the following circuits:
An ignition 1 voltage circuit A chassis ground An ignition control circuit for each cylinder A low reference circuit
The PCM controls spark by pulsing the ignition control circuits to the ICM to trigger the coils and fire the spark plugs. The PCM and ICM are internally protected against shorts to power and ground on the ignition control circuits.

The spark plugs are connected to each coil by a short boot. The boot contains a spring that conducts the spark energy from the coil to the spark plug. The spark plugs are tipped with platinum for long wear and higher efficiency.


Ignition Control Module (ICM) Connectors

Removal & Installation
2.2L (L61) Engine
  1. Turn OFF the ignition.
  2. Remove the accelerator cable from the bracket.
  3. Remove the accelerator cable bracket bolt.
  4. Remove the accelerator cable bracket.
  5. Disconnect the ignition control module (ICM) harness connector.
  6. Remove the ICM retaining screws.
  7. Remove the ICM from the ignition coil housing.

To install:
  1. Install the ignition control module in the ignition coil housing.
  2. Install the ICM retaining screws. Tighten the retaining screws.
  3. Connect the ICM harness connector.

To install:

CAUTION DO NOT wipe grease from the module or coil if the same module is to be replaced. If a new module is to be installed, a package of silicone grease will be included with the module. Spread the grease on the metal face of the module and on the cover where the module seats. This grease is necessary for module cooling.
  1. Install the ICM to the cover.
  2. Install the screws that retain the ICM to the cover.
  3. Install the ground strap, if necessary.

    CAUTION When installing the housing to the cover, make sure the ground strap stays in place.
  5. Install the housing to the cover.
  6. Install the screws that retain the housing to the cover.
  7. Install the spark plug boots and the retainers to the housing, if necessary.
  8. Install the ICM assembly to the engine while carefully aligning the spark boots to the spark plug terminals.
    CAUTION The ICM cover bolts must be installed using isolator washers with the rubber side facing down.
  9. Install the bolts that retain the ICM assembly to the camshaft housing after coating the bolt threads with LOCTITE, or equivalent. Tighten the bolts to 16 ft. lbs. (22 Nm).
  10. Connect the ICM 11 pin harness connector.
  11. Install the bolt to the fuel line retainer clip.
  12. Install the accelerator cable into the hold down clip.

i don't think i'm getting spark


To confirm if your getting spark or not remove the lead coming from your coil to the center of the distributor. Place the end of this lead @ 1/4" away from a clean piece of gronded metal. Have another person crank the engine for a second or two. If you are "getting spark" you'll clearly and probably hear a small blue spark. If you see nothing I'd check in to the crank sensor.
I hope this may have helped,
