supra87 Posted March 25, 2017 Share Posted March 25, 2017 Hi guys looking for some technical advice I've got a 95 import na auto that's decided it will not start I've read the fault codes that point it to being the coolant temp sensor I've replaced this and still no joy it's sparking and geting fuel if I disconnect the plug on the sensor it attempts to start and run very poorly I'm at a loss and can't think of anything else to check any ideas ?

ibby Posted March 26, 2017 Share Posted March 26, 2017 I guess you have checked the new sensor to ensure it meets factor spec, eg ohm's, cold / warm. Next step would be to check wiring for bridging or ECU side Link to comment Share on other sites More sharing options...
