Whenever my car sits for say more then three hours it is slow to start, not from the battery side....it just takes a long time to crank up. If it sits for a few days on end it will take like one minute of cranking to start up. The battery is strong, new plugs wires cap rotor fuel filter and fuel pump.....still haveing issues. Anyone have any ideas what this could be. I have a ZC swapped into an 1988 si crx still running the stock ecu.....got a pg7 to swap in when i get the chance though. Is there a sensor or something that is causeing this starting issue?

nah just drop in the pg7.

ok you think that could be causing this issue....the car ran fine for 12k befor it started doing this.......Grrrrr i hate minor problems like this they are so hard to diagnos.....how do i get to the ECU anyway?

88crxSi

the ecu is right where the passenger's feet go.

so you had this EXACT setup fine for 12k then started starting badly.?

REVS29K

yup....so i started replacing stuff......which is everything on that list.....

88crxSi

you said the battery is "strong" meaning what? it's new? it turns the motor so it's ok, or it's been tested?

what about air filter?

REVS29K

been tested it is like new......airfilter is new!

Mine used to have a cold start problem. would have to crank for like 4 sec. Didnt notice exactly what fixed it but have replaced battery and fuel filter recently and it starts within 1 sec even after sitting for an entire week.

Maybe a dirty IACV ?

REVS29K

what is that and how do i fix that bitch!

quadnie

dump the cat (if u haven't already). That will help the motor breathe a lot better on startup.
