Peugeot 307 1.6 petrol 2005 non start
2005 peugeot 307 1.6l petrol The fault happens when the engine is cold has to be around freezing temp, the engine keeps cranking but wont start then it will just about start but fire on about 1 cylinder with very low idle like it is just about running, the headlamps don’t come on & no lights on the audio in the car, (the lights always come on when the engine is running correctly automatically) & the throttle won’t do anything, then after a few Minuites the lights come on the engine runs fine engine will rev up fine & drives fine no lack of power. There are no relevant faults stored! I have the car back next week to test again, any ideas would be useful thanks!
I would start my problem analysis by finding out why the engine will not start quickly. To get the engine to start and run, it needs only four things, proper spark at the proper time, proper fuel injected into the air streak at the proper time, the proper amount of compression in the combustion chamber, and the ability of the cylinder to pump air. Now what is missing? It seems the electrical
Thanks for your reply I had the car for a few days last year & couldn’t get it to play up until the day the customer needed it back, It was getting milder then & decided to leave it until was cold again, at that point it was in for a service & had the timing belt done, that was spot on so ok, & by the way it runs & General performance I feel that is ok. I had it in for two
Check a wiring diagram and see if the engine, headlights, audio illumination and throttle share anything in common like powers, grounds, relays etc.
What's missing when it struggles to start? Are all the correct telltales illuminated on the instruments? Can you communicate with all modules? If so what are battery voltage levels in each module?
Thanks Steve they are all the things I’m planing to check when it’s back next week! The biggest problem is getting the car then getting it to be a problem when I have the time to do it, last time it wouldn’t play up when I have the whole morning allocated! I have never let a vehicle beat me yet! But just getting a bit more envolved in a few makes I haven’t gone so far with since I got the new
Have you checked IAT and ECT temp pids when cold. Don't know about Peugeot but have had several VW's in here in the past that had bad ECT temperature senders and or wiring that would read too low and vehicle would over fuel on cold start to the point of flooding.
