Hi guys, New to forums for the most part. Looking at some answers for troubleshooting my car. It still has its mechanical fuel pump rather than electric was wondering if I should switch over. I'm having a fuel issue i believe I go to start it, its a hit or miss, but once it gets the fuel its fine, I've been using a basketball pump to put back pressure towards the tank on the inlet so it will start flowing. once that happens it has enough pull to do it on its own. Any reasons as to why its doing this?
