Hey! I'm pretty new to working on cars so forgive me if this is a simple fix or what not. So, my '87 Celica gt-s has lately been deciding when it want to start or not. Sometimes I hop in and it starts just instantly and just fine, and other times I'll have to turn the key a few times to get it to start. To be more descriptive, it doesn't even want to crank, it just makes a little buzzing noise like its trying to get it cranking but to no avail. Depending on the cars mood it could take between 1 second to 10 minutes of turning the key to have it start up. There have been a couple times where it will finally start cranking but it kinda struggles to stay on, to where i have to pump the gas a bit to give it some fuel. Not too sure whats going on here. If anyone could help me out or wants more detail on wants going on let know! Thank you!
