Went out for a short drive this morning. When I got back I parked up the car and shut of the engine. A few minutes later when I should start her up I had difficulty getting her going, the engine started but misfired badly. It then cut out and refuses to start. I have a Petronix but there is a spark. Any ideas on where to start?
Thanks |

(IMG:style_emoticons/default/idea.gif) I thought the cht circuit open would make the car run rich. If it is running rich then I wouldn't think spraying additional fuel would help. I put a pressure gauge in place of the cold start injector. In my car, I never need it anyway so the gauge stays in place |

If you just ground the CHT wire to the engine case it should start IF the temp sensor is the problem. Shorting that wire to ground just looks like a head temp of greater than 300F. So it should run rough but start because the ECU just thinks the engine is warmed up when it is not. |
