So my car was dieing after i would turn it off and i needed to jump it every time to get it started. I took the alternator and battery in and both were bad plusi got new battery cables becaause they were fuzzy with corrosion. The starter is almost brand new. I changed out the battery, alternator, and cables. I am stupid and wasnt paying attention and did the battery cables on the wrong terminals and something around the starter solenoid smoked and popped. My car wouldnt start so i bought a new solenoid and replaced it so we (me and my uncle) tried to start it. It wouldnt start. Sometimes it sounded like it was going to go and the crank would do a full rotation but nothing more. We didnt know if the battery was low even though it said it wasnt so we hooked up jumper cables to his van and tried but still just gives a quick try not even a turn almost as if something is holding it back. I do not know if this is anything but before the fuel relay would start up after turning the key to turn on the lights and stuff and it would stop after a few seconds. Now it justs keeps going. Lights all come on (cepts the speedometer and other meter lights. Amp lights and check oil and all those come on.) I dont think it is any of the parts i hooked up else the lights wouldnt come on and the starter would try to start it alittle. I am behond myself on what to do. I really want to ride this out until i get a new ride so does anyone have an idea?
