2003 Peugeot 307cc 2.0 Petrol. Does not start but will crank. Code P1621 on the OBD reader
Just had all spark plugs and 2 injectors replaced. Drove home the previous day with no issues whatsoever, parked the car and left it overnight.
The following day the car would not start. The engine cranked / turned but would not start. The same battery started the car with no issues whatsoever the day before.
This is during the summer, so temperatures are sufficient (it's not a cold weather problem)
The fuel rail has fuel, so it's not a pump issue. (I managed to spray my own eyes with fuel when checking, yes I know I should have known better, but I didnt.)
I also tried leaving the battery disconnected for a few hours and reconnecting it, but that did not solve anything.
Maybe important
The Key housing was pretty banged upso I changed the key from the original housing to one that I bought on amazon. (just the plastic housing)
I was very careful with replacing it, I didnt replace anything electronic and the key still opens the car as it did before. (if it opens the car then it must be paired right?
I have checked and the OBD scan tool I have shows code P1621 which suggests either a crankshaft error or the immobilizer getting triggered and an issue in connection between the ECU and the BSI (that would require the unlock code, and god knows where that is on a 20 yr old car)
I'm thinking of things that might be wrong here:
1.- the crankshaft sensor?
2.- the coil? (so no spark)
3.- something with the ECU / BSI software? (immobilizer)
4.- Somehow the battery voltage... ?
5.- key unpaired in some way?
6.- I've seen videos where the BSI unpairs with the ECU and you need to retrieve the immobilizer code before you can do anything.
1 and 2 are unlikely as the car drove perfectly fine from the garage the day before and was not touched overnight.
I have an old PP2000 that I run on a windows XP VM, so I'll give that a go.... Tomorrow.
Any ideas / advice would be greatly appreciated, I've tried doing my homework but I'm no mechanic.
