You could even substitute it for the oil temp sensor temporarily.. One way to find out if its an electrical or true plumbing gremlin. Given the issues you've been having, my vote is electrical (sensor fault, wiring fault). --------------010506070201060001000702 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit On 9/28/2010 9:42 PM, Chris Barber wrote:

The engine appeared to be running fine before I shut it down. I checked the wire to the back of the engine monitor and all was fine. I also checked the continutiy of the wire to the sensor and it was good. I started the engine again and it started fine and seem to run fine, however, the OP did not kick in so I shut it down again
