So I have a 1987 Nissan Laurel (automatic), which has been sat for around 14 years (it was my late Grandads). We bought a new battery for it to see if we could get it started, but there was no lights, nothing. On further inspection I found the continental fuse (found on the wire which attaches to the negative terminal) to be broken; I should note it didn't look like it had blown, just broke.
After replacing this fuse, I got lights. However, when you turn the key to start the engine, there's a single click sound (maybe the fuel injector or something?) but it blows the fuse. So essentially I can't put the key in that position otherwise it'll just blow the fuse. After doing that there is this smell of petrol, I'm assuming that's normal, but thought I should mention in case it isn't.
I was hoping someone may be able to provide some advice on where to start looking to stop this fuse blowing. Something is causing it to short but I can't figure out what. I have tried with the distributor wire disconnected, but to no luck. Same result with the actuator wire disconnected.
I am not particularly knowledgeable about cars, but I would like to try and get this car started. I appreciate all advice! I should also note the car has only done 23,000 miles, and was working fine when it was garaged.
