Hey i have a small problem with my car, when I start it or try to start it, it won't actualy fire till I let of the key, could this be a battery probelm? I don't know if it has any relation but yesterday when I replaced the votlage regulator it seemed to pop off fine, but then it was a bit warmer yesterday and so was the engine. The odd thing today was that I drove it for 1/2 hr then parked it and then tried to fire it up an hour or two later and it did what I stated above, where it didn't fire till I let off. Battery probelm? or just the colder temp?
