Saga Continues [ Feb 12th ]
Today, much to my dismay, the car failed to start. It was at rest for approx 30 min's after it had completed a 15 mile journey. The Immobiliser symbol DID turn off after a second or so BUT the Injector symbol remained ON.
Eventually, after opening the bonnet [ this is a clue to my latest theory ] where I spent a few minutes looking at fuses & relay. I swapped the A/c relay for the Fuel Injection System relay, turned the key & it started. Delighted with my so called *repair* I went for a 5 miles spin & I got the car up to operational temp.
Approx 30 min's after this spin the car failed to start again.............NOW this is getting tiresome but I'm starting to looking at this situation as a challenge that I will over come.
Sitting down a while to ponder why this is happening a thought occurred to me.......... Its a temperature related issue.
My *new* theory is that if the car is completely cold or up to operational temperature the car will start without fail. BUT if the car is cooling down, between 50 & 55 on the temp dial, the car may not start.
1. My car has 3 dials in the center console, one is for temperature. When the car is upto operational temp the needle sits half way between 50 & 70, assuming linear calibration, that should be 60 deg C approx.
Is 60 deg C *normal* or is it on the low side? From previous cars this seems approx 30 deg C low to me
3. I looked around the engine to find only ONE temperature sensor which is fitted into the thermostat housing, located near the battery. Disconnecting this sensor the temp gauge in the center console drops back to below 50 deg C & the car *splutters* alot.
4. Are the more than ONE temp sensor? If so where are *others* located?
5. Did any of you hear of an issue like this before?
Several times during the day I would go for a 5 miles spin to get upto to temp. After each spin I would then allow the car to cool down with the bonnet open. 4 times out of 5 the car failed to start. I noticed that the needle of the temp gauge would be a *tad* above the 50 deg C. I am convinced at this point the Immobiliser is function 100% & is NOT the reason for the cars current problem.
PS I have am just after reading the post about the 147 temperature gauge question & now I wonder is my car running too cold or is the temp sensor defective?
It think it would it be worth while to replacing the Sensor &/or Thermostat.
