Just recently my 1991 Accord (270K miles) has developed this slow cranking start. It still starts but it doesn't have the normal sound/start time as it did before. It's been like this for a week now so I don't think that the alternator or battery are the culprit. If it were the alternator, the battery should have run out by now....and it's not the battery because I've tried a new battery and it does the same thing. I haven't checked the alternator yet, but I don't think that the alternator would cuase the starting system to become slow. Don't forget, its just slow but it always starts. Could the starter be the problem? Can anyone think of anything else?

Things to note: the starter and alternator are still the original OEM parts.

Thanks in advance for any comments/help!
