Temp is 225 and fans not kicking on. Replaced the temp. sending unit (with the wires that sends the signal to the ecm). I thought that fixed it but it didn't. If the thermostat is sticking could it be hot and the ecm not command the fans to come on? Car is just idling. I even got a new chip from turbobob when this was happening last time. I know the fans work because they come on occasionnaly. Thanks.
