To replace front motor support ?, can I lift engine enough to replace support without detaching anything. If not what would need to be detached. Thanks for your help.

B0100:
Perform trouble checking for the following: the front end sensor, the SDM module, the SDM wiring harness connector. Damage to the following parts needs replacement or repair. For the DTC B0100, detach the front end sensor1 connector and also detach the SDM connector. Perform trouble checking of the signal and voltage circuits between the SDM and the front end sensor for a short to voltage and for a short to ground. Reconnect all the SIR components and if the DTC B0100 is present then the front end sensor1 has to be changed.

i could not find anything on the B0140 code so i included the B0104 incase of typo

if im not mistaken the number 3 coil is on the right hand side of the motor so you will need to remove the intake manifold to gain access to it.
Intake Manifold Removal

1. Remove the engine cover (if equipped).
2. Remove the air filter outlet pipe.
3. Remove the positive crankcase ventilation hose.
4. Remove the air cleaner resonator.
5. Disconnect the throttle body electrical connectors.
6. Disconnect the electrical connectors.
   
7. Detach the vacuum hoses.
   • Press the retaining ring. (1)
   • Detach the vacuum hose. (2)
   
   
8. Disconnect the vacuum hose.
   
9. Detach the injector harness electrical connector from the intake manifold support bracket.
10. Remove the intake manifold support bracket.
    
11. Detach the engine wiring harness bracket.
    
12. Detach the intake manifold support bracket.
    
    NOTE: Remove and discard the O-ring seal.
    
13. Detach the throttle body.
    • Remove the retaining bolts.
14. Remove the intake manifold.
    • Remove and discard the intake manifold gaskets.

You will have to do the following:

1. Detach the cable from the negative side of your battery.

2. Remove the cowl vent grille.

3. remove the wiper linkage stud nut, detach the wiper link and unplug the electrical connector, then remove the motor assembly-to-firewall bolts, detach the motor and lift it from the engine compartment.

4. Installation is the reverse of removal.

Its going be tough to pull out anything other than a small 4 cylinder without a hoist. You could use a comealong. Its like a small hoist, has a chain and a lever you can use to lift the engine. It has a hook on it to allow you to attach it to something.

But to be able to use it you need to put the car underneath something that is sturdy enough to support the weight of the engine, like a large limb on a tree or a metal frame of a garage or something like that.
And you will need a sturdy chain. The bigger the better. Attach the chain to your engine lift hooks.
Get some grade 8 screws,nuts and washers from home depot. Get the largest diameter screws that will fit through the links of the chain. Make a loop on each end of the chain by putting the screws through links and tightening the nuts on the screws. Put the loops you made on the engine lift hooks. Attach the come along to the tree or whatever you can find thats sturdy enough to support the weight of the engine with another chain. Then lift the engine out.

you will have to detach the ac compressor and power steering pump and tie them out of the way with pieces of wire. That way you wont have to discharge the ac system or drain the power steering fluid. Remove coolant hoses and fuel lines. And remove the half shafts for front wheel drive. Then detach the motor mounts/transmission mounts. Of course, theres a lot of other stuff you need to detach, but im sure you know that already.

You can rent engine hoists for like $35 a day from a Taylor Rental or other equipment rental
company. Rent it one day and take it back and rent it another day when you are ready to
put the engine or another engine back in.

This procedure work for door lock, but necessary you need take off the trim panel, then could helpfull...



Fig. Exploded view of the front door trim panel - 2005-06 and 2007 Classic models (click image for zoom)

1. Disconnect the battery ground cable.
2. Disable the Supplemental Restraint System.
3. Remove the door trim panel. Refer to the illustration for the mounting screw and lock tab locations. After detaching the hardware, carefully pull it away, then lift it off the door just far enough to detach the electrical connections from it.
4. Carefully detach the water shield from the door; this will be reused upon installation.
5. Disconnect the inside door lock rod from the handle retainer clip.
6. Detach the door lock rod from the retainer clip.
7. Remove the rubber plug to access the outside handle rod. Disengage it from the clip and disconnect the lock cylinder rod.
8. Detach the electrical connector and remove the lock from the vehicle.
9. Installation is the reverse of removal. When installing the lock, tighten the screws to 89 inch lbs. (10 Nm).

Put the car on stands and put a jack within a few inches of the under side of the engine. Loosen the bolt mounts by about have a turn. Have a friend use a length of timber and use jack top as a lever fulcrum to take the weight of the engine off the mount whilst you remove the mounting bolts. Take care not to put any load on the oil pan as it can crush quite easily. You should be able to adjust the engine attitude about two inches without having to detach anything, this is enough room to get the old mount out and therefore the new one in. Take your time and keep safe

TESTING WARNING
During the following test, the starter motor must not be energized for longer than 5 seconds, otherwise you run the risk of burning out the starter motor coil.

1. Remove the starter motor from the vehicle.
2. Detach the field coil lead from terminal M on the starter motor.
3. Using jumper wires, connect a 12 volt battery to the starter motor so that the negative battery terminal is attached to the starter motor housing and to solenoid terminal M, and that the positive battery terminal is connected to starter motor solenoid terminal S. The starter motor plunger should move outward; if it does not, replace the solenoid with a new one. Fig. 1: To test the solenoid plunger, first detach the field coil lead from alternator terminal M, then attach a 12 volt battery to the starter motor as shown . . .
   Fig. 2: . . . then detach the negative jumper wire from terminal M. The plunger should remain extended
   Fig. 3: Detach the other negative lead from the starter motor housing. The solenoid plunger should now retract to its normal resting position
   Fig. 4: Use an ammeter to measure the amount of current draw the starter motor uses
   
   
4. Detach the negative battery jumper wire from terminal M on the starter motor solenoid, and check the plunger for movement. The plunger should remain extended; if the plunger returns to its resting position, replace the solenoid with a new one.
5. While observing the solenoid plunger, detach the negative battery lead from the starter motor housing. The plunger should return to its normal resting position; if it does not, replace the solenoid with a new one.
6. Reattach the 12 volt battery and install an ammeter to the starter motor as shown in the accompanying illustration. The starter motor should rotate smoothly and steadily with the pinion gear moving out, and the ammeter should display less than 60 amps at 11.5 volts (Samurai models), or 90 amps at 11 volts (Sidekick, Tracker, X-90 and Sidekick Sport models). If the ammeter does not display the specified values, or if the starter motor does not operate smoothly and steadily, replace the starter motor with a new one.

REMOVAL & INSTALLATION

1. Disconnect the negative battery cable.
2. If necessary for added under-vehicle clearance, apply the parking brake, block the rear wheels, then raise and safely support the front of the vehicle on jackstands.
3. From beneath the vehicle, label and detach all wiring from the starter motor solenoid terminals.
4. Remove one of the two starter motor mounting bolts and loosen the other bolt until it can be turned by hand, then support the starter motor with one hand while removing the last starter motor mounting bolt.
5. Lower the starter motor down and away from the engine and transmission. To install:
   
6. Hold the starter motor in position and install the two mounting bolts. Tighten the two bolts securely.
7. Reattach all applicable wiring to the starter motor solenoid. Ensure that the wiring terminals and connectors are clean and free of corrosion.
8. If necessary, lower the vehicle.
9. Connect the negative battery cable.
