only time it does this like when i let the car sit overnight

 

bump any help?

 

did you change the ICM?

 

im still getting spark though it it was bad them i wouldnt get spark plus it will start after i crank and crank the car on and off for like 5 mins.

 

is this a good way to test it the coil and icm or anyone know a better way ?

Use a test light. Clamp the alligator clip on the positive terminal of your battery and touch the probe to the negative side of you coil. Have someone crank the engine over and look for a flashing light (interrupted ground). If it is interupted, replace the coil. If it does not flash, replace the ICM. I've seen way more ICM's go out than coils.

 

when yiou changed your distributor, did you tighten everything down right? nothing loose?

almost sounds like your timing can be off.

 

when i do get the car started it runs perfect .If timing was off wouldnt it run like crap when it starts also ?
this got me all confused

yes, i miss read something sorry.

 

still confused???????????

 

have you tested your ICM (igniter)? its a good idea to change out the igniter when you change out the coil. one tends to go out not too long after you replace the other.

good luck!

 

Any codes?
Check ECT sensor.

 

no codes now someone told me it might be an injector going bad could that be it

got fuel got spark car wont start when sat overnight when cold ?

 

new day bump

 

you might not have enough compression to start it cold so check that. if its a high mileage engine you might want to do a rebuild. if you have a big turbo that requires low base compression then you might get yourself a freezeplug block heater, the best quality for your car will come from your local honda dealership.
