Default need HELP!!!! 89 civic si, b16

ok, ive searched and searched and you guessed it, searched. no luck....
week before last, i drove my car one day cause it had set 3 days prior, cranked and drove no problems, came home parked it. went to get in it the next night, no crank, just clicking. tried to jump it a couple of days later, no luck. charged the battery, no luck. while messing with it i noticed my vafc and fan weren't turning on unless i tapped the clutch pedal. check every where no cut wires, tried cranking with starter out of car to see if it would engage at all. no luck wouldnt crank. now vafc wont come on, no check engine light with turning key into on position, no battery light either and no fuel pump. no blown fuses. checked ignition wiring at the key to the fuse box. all 12v. 12v at starter, until i turn the key.
also when turning the key, no light on the ecu, til i turn the key like trying to crank the car.
headlights, sunroof, power mirrors, seatbelt light, brake light, hatch light, cluster lights work.
motor is not locked up, checked that.
had starter tested, and battery tested.
tried another ecu also.
really could use some help.
could it be the main relay?could it be the neutral safety switch? could it be anything?

what am i missing? any help would be appreciated. dont know where to look now.

Check the big fuses under the hood. Also check the alternator selonoid fuse. You could also check the thermostat ground.

The one above the hood latch is the main relay.

more info then just "fixed" please. this is supposed to be an informative forum. you started a thread that will be here forever. next time people search a similar problem they might find yours and you will have been of no help at all. a waste of space. please fill us in.

sorry about the short unimformative answer....

it was the damn ground on the battery, one of the screws on the cable end was a little loose, causing the connection to not be good.

check grounds....lol. i did check em but evidently not good enough.
