96 integra wont start, need help with diagnosis
my car wont start as stated, ive checked the battery and starter, fuel pump is working, ive checked all my electrical connections ie. battery, battery terminals and engine grounds. now b4 the car woulnt turn on, it ran perfect for a whole day till that nite when it wouldnt start, had to get it jumped, then i couldnt jump it anymore, had to clutch start it. now it wont even spin the flywheel, just clicks whenever i turn the key and the main relay clicks fast, so does anyone know the cause of all this? i really want to drive my car and not spend a ton of money at a shop
A "fast" clicking relay is an indication of a grounding problem.
You said you checked the engine grounds, what grounds exactly, and how did you "check" them.
Your main grounds are the batt. post and ground cable clamp, the batt. to car chassis ground, and the car chassis to engine ground, you do not "check" these ground points, the proper way is to "redo" the grounds, disconnect, clean both contact surfaces, [EG; the batt. neg.(-) post, and the inside of the neg.(-) batt. cable clamp] then reconnect making sure the connections are tight without over-tightening.
You should also do the same with all the main power connections, batt. pos.(+) post and cable clamp, batt. to engine bay fuse box, the main fuses, [screw down ones], the batt. to starter motor, the alt. charge line at both the alt. and at the engine bay fuse box.
Some clarification is needed...
When you say, "my car wont start" does that mean engine will crank, [starter motor works] but engine will not fire/start/run or does it mean engine will not even crank, [starter motor not working]?
I assume you mean the latter, [at least now] as you also say " now it wont even spin the flywheel, just clicks whenever i turn the key" .
Try this, before doing anything else, turn on the dome light or leave door open so it stays on, keep an eye on the light and try and start the engine, what happens to the dome light?
The above assums that your electrical works, head lights, horn, radio, blower motor, dome light and so on. 94

ok well ive replaced the head to body ground, havent changed out the other grounds, ive cleaned the battery terminals, ive tightened them as much as it will allow me, ima replace those 2. what i meant the car wasnt starting was the starter was cranking a little for a while but then it stopped that and now just clicks with the key turning. well thank you for the advice. ima go check that stuff now and let u no what happens, sorry for the long reply, i work alot.
well now that i have replaced two of my grounds and cleaned all the contact points in the engine, ( all the battery hook ups, tranny to body, head to body, ) the cranked once, and then went back to clicking but now my main relay doesnt click super fast and the dome light almost turns off with me turning the key so what does that mean? battery needs to be charged now?
Yes, it sounds like a low batt. now, charge the batt. and try again, or try a jump start.
Connect jumper cables from a running car, neg.(-) jumper to to running car last, let the running car charge your batt. for a few min. TURN OFF the running car, then try and start your car, AS SOON as your car starts, disconnect the neg.(-) jumper off your car.
DO NOT, under any circumstance, leave running car running while you try and start your car. 94

If all other spark, fuel, grounds, etc are good you could have a clogged exhaust system, with the front o2 out of manifold crank engine, if it starts your cat or exhaust is clogged.
