i drive a 2000 civic coupe... SOHC.... its was USDM head and Jspec block...

when the car isnt used for about around 3 -4 hrs it wont start up, when i get in and try to start it up.. it does nothing.... no click... no trun over.

just replaced the battery.. but heres the thing....

i'll try it over about 10 more times.. get all pissed off... look under my hood and think.... WTF is going on here.... get back in my car.. and the thing starts right up...

note:: car runs fine and starts up every time.. when im driving it like every day.. stuff but it does this when i leave the car.. say over night or somthing.. i dont get it.

 

fuel pressure needs to build again or you flooded the cylinders

 

what can i do to fix this?.....

HAVE YOU CHANGED THE GROUND? WHEN YOU GET ALL PISSED YOU MIGHT BE MOVING THE GROND AROUND. TRY CLEANING BOTH GROUND SPOTS. IF THAT DONT WORK THEN TRY CHANGING ALL POWER CABLES.

 

all power cables?... wtf... the neg and postive are on snug... i dont get it... what about the fuel pressure?... expletive.

TEST YOUR STARTER THEN IT MIGHT BE GOING BAD. FROM WHAT YOU ARE SAYING YOU DONT EVEN HAVE A CLICK SO THATS POWER. IF ITS NOT GROUNDED HOWS IT GOING TO WORK RIGHT.

 

yea ill check those thing out this weekend thanks man

Just calm down if you want help. 1st hondas are very sensitive to bad grounds. Check all the grounds from the engine to the body and the trans to the body. Change any that have corrosion or frayed wires. 2nd look at the positive power cable for the same type of thing. then check for power from the battery to the alt and make sure these connections are good. Have a friend try and start the car and listen for the starter to try and turn over. If you still have nothing you could have a bad ign switch and it is time to pull the manual and trouble shot that section

 

OTHER THINGS IT COULD BE IS YOUR IGN. BAD CONNECTIONS BAD WIRES OR TRY IGN. FUSES SOMETHINGS FUSES LOOK GOOD BUT ARE'NT AND THEY HAPPEN TO WORK SOMETIMES. SOUNDS FUNNY BUT CHECK THEY UNDER THE HOOD AND DASH.

 

YOU CAN CHECK IF YOUR IGN. SWITCH IS SENDING A POWER OR NOT BY USING A DMM. PULL OUT THE IGN. WIRE FROM THE STARTER AND TOUCH THE WIRE WITH THE POSITVIE END AND GROUND THE OTHER THEN HAVE A BUDDY TURN THE IGN. YOU SHOULD GET A READING IF NOT THEN YOU GET A BAD SWITCH OR SOME WIRES ALONG THE WAY.

 

BLU EG turn off the caps lock there is no need to yell at everyone.

 

SORRY I TALK LOUD.

 

It's a ground, dude.

The reason it's starting up is the shock value the chassis gets when the hood slams.

Or a door closes.

Definitely a loose ground, check them.

Poor internet skills.

If the checking your grounds doesn't work, do you have an aftermarket alarm? If so, does it have a ignition kill circuit? The relay may be sticking.

Do you hear the main relay energize when you turn the ignition?
