90 bronco burning through solenoids

I just bought this 90 bronco with a 302 fuel injected and an e40d trans. Solenoid stuck every time I started it so I replaced it. And after 3 exactly 3 times of starting it (just takes a bump of a key to start) it stuck again. What could the issue be? They wear but not this quickly. Also for some reason the trans jerks into second hard and it happens at 10 mph. Doesn’t matter how I take off. What’s that about?
