So I just took the truck for a short spin on the highway, speeds of about 60mph for about 40 miles round trip, and now the blazer doesn't fire up like it used to. Basically, I try to start it and it'll turn over and over for a couple of seconds. I stop and let the starter cool down, then try again while pumping a little gas and it rumbles to start. After that, it'll restart just fine while the engine is warm, but I don't seem to have a check engine light, so I'm curious as to what you guys think.
