So I just recently got this Celica to learn manual. I’ve owned other Celica’s on the past but they were all auto and newer. When it was being driven home the battery died (different one that’s in it now) and had to jump it and finish the drive home but that could also be because the battery connections were loose. After this It’s been very inconsistent on if it will start or not.im haveing to replace the connector for the alternator(it was allowing for the actual connections inside the plug to be loose)for the alternator and I’ve also swapped the small 70amp alt or to a 2000 Camry alt from a different 5sFe. Also I was told that the camshaft position sensor plug also need to be replaced because if it’s loose also won’t let car start but it will crank. I’ve assuming it the battery connectors that are the issue because I really can’t think of any other reason why it dosent want to start. But at the same time the previous own apparently drove the car like this for 3 years no issues. I get power in cab and can running every thing electric related. Also I can hear the pump kick on when trying to start. I’ve tryed using the obd1 port but it doesn’t seem to want to out put a code it kinda just flashes rapidly forever I’ve noticed or maybe not but I did sit there and watch it for 2 mins straight and it didn’t pause once. im completely lost here tbh because nothing seems to be wrong ?
