No start i've got a honda prelude i had it running while taking off the spark plug wires to check if my plugs were firering ok i got to no.4 when my engine died, i then decide to change the wires while changing the wirers i heard a noise sound like a fan turned on i checked the radiator fans they were off, but the noise sound like its coming from the alarm i then remember i didn't switch the ignition off and my battery was drainded, after replacing the wires and the battery the car won't start, fuel is fine but i'm not getting any spark, could this be my immobilizer never had no problem with it car always start first time, thanks

You may have gotten air in the fuel tank when you filled it. Be sure when you tighten gas cap to hear at least 3-4 klicks.

Bad or loose ground wiring. Check ground by driver side intake manifold

Sounds like the catalitic converter/s are clogged up. This would cause low air flow and low compression. I've seen them so bad that they dropped the compression down to 60 lbs.

1. Locate the service check connector and, if applicable, remove the cap. On 1988-91 Preludes, the cap is yellow and the connector is located next to the vacuum control box in the engine compartment. On 1992-95 Preludes, the service connector is located under the middle of the dash. On 1990-93 Accords, the connector is blue and is located behind the right front kick panel, under the dashboard. On 1994-95 Accords, the service connector is located behind the glove box. Use a jumper wire to connect the two terminals of the service connector.
   

1. Following the manufacturers instructions, connect a timing light to the engine. The positive and negative leads connect to their corresponding battery terminals and the spark plug lead to No. 1 spark plug wire.
2. Make sure that all wires are clear of the cooling fan and hot exhaust manifolds.
3. Set the parking brake and block the front wheels. Start the engine. Check that the idle speed is set to specifications.
4. Point the timing light at the timing marks. On all models except 1994-95 Accords, the marks are on the flywheel. On the 1994-95 Accords, the timing marks are on the crankshaft pulley. When the engine is idling, the red mark must align with the pointer. Some timing marks are indicated by 3 lines; the center one must be aligned with the pointer.

1. If necessary to adjust the timing, loosen the distributor hold-down bolt(s) and/or nut and slowly rotate the distributor in the required direction while observing the timing marks.
2. To complete the adjustment operation, tighten the hold-down bolt, taking care not to disturb the adjustment.
3. Switch the engine OFF . Reinstall the rubber plug in the timing window and remove the timing light. Remove the jumper wire.

Sounds like a bad starter or teeth missing of the flexplate or flywheel. Is it a stickshift? Can you push start it?

you probbably damaged the distributor coil when you pulled the wire off
recommendations:
try pulling battery lose for few and see if it helps
replace distibutor coil and wires to plugs and replace plugs

Bad distributor if the main relay was changed. Good luck and thanks for using FIX YA

I suspect that your spark plug wires or your distributor is going out. Check your spark wires and distributor. To do that take out #1 spark plug wire from the spark plug. Next take out your spark plug then put it in the spark plug wire. Then turn on car and take a look at the spark plug to see if it's getting a spark. Do this with all the spark plug. If it is your spark plug wire I would replace all of them.

DOES IT CRANK OVER/IF NO CLEAN YOUR BATTERY CABLES AND CHARGE OR REPLACE YOUR BATTERY.IF STILL NOT STARTING PULL ONE SPARK PLUG OUT AND CHECK FOR SPARK.THEN CHECK FOR FUEL/
