2007 RDX long Cold Starts. No CEL
I have a weird problem I can't figure out. 2007 RDX 166k.
The first start of the day will take 4-10 seconds. Once it starts it runs fine. No Smoke. Idles Fine. no CEL. The longer the car sits the longer it will take to start. The rest of the day the car will start fine.
Seems like it is losing fuel pressure. I replaced the fuel pressure regulator, and the issue was not fixed. I am suspected the fuel pump next. Does anyone have any other ideas?
The car has new plugs, coils, air filter. Issue seemed to get worse after the coils were changed. I think it's a coincidence. seems to get worse with cold weather. The new coils are Denso, OEM. from rock auto. It doesn't make sense that coils would be the issue and only be problematic on the first start of the day.
love to hear your ideas.
