Hard Starting

[marcre]

What are some reasons for hard starts? My 99 Rodeo V6 cranks excessively. It seems to be getting worse. Weird thing is, some days it will do it every time I go to start it. Then it will be fine for days. I really do not know where to look. I do not want to replace the battery if it is something else. Within the past several months I have replaced the IMG's, fuel and air filter, cleaned the EGR and throttle body, changed the PCV, changed the spark plugs, changed an O2 sensor and I run gas treatment every few months.

Thanks,
Marc

Do you turn the key to the one position, wait 5 seconds (for the fuel pump to prime the system) and then start it?

If so then it could be a bad fuel pressor regulator.

Ryan I checked the link you put up and I don't seem to have all those symptoms. It just cranks a real long time sometimes. Others it is fine. I will keep an eye on it though.


Thanks,
