Ok so to give back story on how we got here: I bought the car from a guy about an hour and a half from me who had put on a new head, gaskets, pumps, belts, etc. The car was in his yard and has been parked for a couple years. Records pointed to 2015 but it has a 2017 emissions sticker. I bought the car and drove it home fine. Only issue was the radiator needed replaced. Fast forward to last week. It was the week before school started and I finally got the car on my insurance and got tags for it. That Saturday I replaced the radiator. When I did that I also did the hoses. Once I was done I headed to a friends. After 5 minutes of driving I noticed the temperature gauge had just hit red so I pulled over. 15 minutes later I drove it 2 blocks worth down the interstate to Home Depot where I found the radiator hose on the top had blown off due to me not putting the clamp on correctly. Me and 2 guys who stopped helped me get it fixed and filled the radiator. After this the car would not start. 30 minutes later we had sprayed starting fluid in and it fired but was still overheating. The oil was normal still. So we let it set for 2 hours before I discovered the radiator hadn’t been filled all the way because the guy didn’t have enough. Drove the car home fine but the exhaust would pop/gurgle every now and again (it also has a major leak). Later that night I went to start it and a bit of white smoke puffed out but the car ran. Oil was still unchanged. The next day I put blue devil gasket sealer in it and it ran for 50 minutes. After parking it the car would no longer start. I had replaced the plugs and wires. Upon putting the old plugs in the car would start but it would take a lot of messing with the pedal and it was misfiring in all cylinders. Also my radiator holds pressure when the car is off and cool. Yesterday I took the #1 plug out and turned the car over and clean green coolant came out. The oil was still the same so it made no sense. The car wasn’t overheating nor smoking. After this the car would turn over as it always has since this issue. It’ll turn over for a bit before it starts firing and then it builds up only if you hold the pedal to the floor and eventually runs but this time it ran just like it always has. The check engine light gave me code 43 which means fuel system. This went away after shutting the car off and restarting and I drove the car for a bit and it was completely fine. But strangely enough the temperature would go up after you shut the car off and go back down once it started. The longer you leave the car off and the more it cools down the harder it is to start again but once it does it runs like normal with no issues.
