If in fact they are doing it sometimes, but not all the time, this is indicating worn out belts, and they need replacement. Belts can look good, but can slip and squeal when they get hard and brittle. I, too, have had that experience with my Hondas. If the belts did it all the time, you would look for a defect in of the components that the belt is driving. ( Water pump, a/c compressor, idler pulley, power steering pump, alternator, etc.) God bless your efforts.

Don't forget there are two set of fuses..under hood and under dash. I don't like running around without a map so if you have a wiring diagram that would help. If not the owners manual tells you what fuses protectl what.

Should be a black hose from the inlet manifold to the rocker cover the p.c.v should be at the end of the hose.

try each different key position

Different make and model of cars have different location for it ECU however i most case the ECU is located in the passenger area or engine bay. If it is in the passenger area, most likely it is behind the radio in the center console or behind the glove box.

It isn't too hard to get it started, but your steering will still be locked without a key. You can unscrew the electrical section of the ignition switch off the mechanical section and turn it with a screwdriver, then to be able to turn the wheel you remove the mechanical section, usually with a hammer and chisel, since it is held on with anti-theft breakaway bolts. A locksmith might be easier.

Remove the thermostat and run the engine at idle until it starts to overheat. If it does then the radiator may have clogged veins and needs replacing.

You have got good use of it. I through 200,000 was it. Its a neutral switch. About time for new one. I am on fixed income too. Know how you fill.

are you sure you the adjustment to it is correct the button in the end of the switch has to be fully depressed to deactivate the circuit

Check the fuses, if they are all good then change the window motor on that one door!

I don't believe that the 1991 Accord DX had a Honda accessory alarm option, but regardless, factory or aftermarket, it was wasn't installed at the factory, it was installed at the dealer or an aftermarket store. Just remove it, and reattach any cut wires.

Then, do the usual checks for spark at the plugs, and fuel at the rail. Hope this helps.

CHECK TO SEE IF YOU DIDN'T PUSH THE PINS IN THE FUUE BOX TO DEEP THAT THE RELAY IS NOT MAKEN CONTACT..

Please see my tip at http://www.fixya.com/cars/r6223989-ignition_coil_doesn_t_spark . These are generic instructions--specific instructions are pasted below from Autozone.com. If you get stuck, please get back to me.

Use a test light to check for power to the coil on the black wire with a yellow stripe--see procedure below and other tests you can run. You will need a volt-ohm meter to run most of these tests.

The system used on 1990-95 Accords and 1989-95 fuel injected Preludes uses the distributor components to signal the engine computer. The ECU triggers the spark through the igniter unit and coil. This spark timing is controlled by the computer as an integrated function of the fuel management system. The distributor contains a crankshaft angle sensor and a No. 1 Cylinder Top Dead Center (TDC) sensor. Using these and other electrical inputs, the computer controls spark timing electrically.

1990-91 ACCORD
See Figure 6

1. Remove the distributor cap, rotor and shield.
2. Label and disconnect the 4 wires from the igniter unit.
3. Switch the ignition ON . Use a voltmeter to check for voltage between the black/yellow wire and ground. Battery voltage should be present. If the voltage is not present, check the black/yellow wire between the igniter and the ignition switch.
4. Check for voltage between the white/blue wire and ground. Battery voltage should be present with the ignition ON . If voltage is not present, check the white/blue wire from the igniter to the coil and test the ignition coil.
5. Turn the ignition OFF . Check for continuity in the yellow/green wire between the igniter and the ECU.

Fig. Fig. 6: Terminal identification on 1990-91 Accords

1. Check the blue wire for continuity between the tachometer and the igniter.
2. Check the resistance between the terminals which connect to the blue and white/yellow wires. It should be between 1,100-3,300 ohms. If not, the igniter must be replaced.

Coil test:
1990-91 ACCORD

See Figure 16

1. The ignition coil is contained within the distributor. With the ignition OFF , remove the distributor cap.
2. Remove the screws securing the black/yellow wire and white/blue wires from the terminals. The black/yellow wire is connected to the primary positive terminal and the white/blue wire is connected to the primary negative terminal.
3. Measure resistance between the terminals. Resistance should be between 0.6-0.8 ohms.
4. Measure the resistance between the primary positive terminal and the secondary terminal. Resistance should be 12,800-19,200 ohms.

1. All test conditions must be met. If any test condition is not satisfied, the coil must be replaced.

main relay.there is a relay underneath the dash thy are culprit of no starts on honda accords its gray in color

Relay or fuse?

The Honda system uses a coil that mounts inside the dist, right ?If you can check voltage output at the coil tower with the cap off you can find out if the coil is firing. If it is, then yes the rotor could be the problem. The voltage has to go thru the cap to the center of the rotor then to each plug terminal. The spark can jump thru the rotor and ground thru the dist shaft.

The o2 sensors because the car may have more than one, are located before the catalic converter, they look like spark plugs with 3 or more cables running from the top, scan the car to check for other codes.

This is a trans issue, and OBD scanners won't read these. Jump the 2 pin OBD connector and count the light flashes to get the code #. Then go online to find a list of codes for your Honda.

check your distributor and ignition coil.
