so over the winter i went to change the oil in my 2000 750. i ended up stripping out the drain plug and for some stupid reason it was left for a about two months without much oil in it. This past weekend i put in a helicoil kit, charged my battery and drained the tank and put in new gas. Went to start it up but no luck. It will turn over but thats it. So i pulled the plugs and replaced them, made sure all the wires are good, and still nothing. So i pulled the injectors to find a small amount of rust one them. I dunked them in some sea foam for a while and also added some to my gas tank and still nothing. Then today i pulled them out and tried turning it over while still connected to the fuel rail and i didnt see anything spray. so im thinking its either something wrong with the fuel pump, which does prime when i turn the key, or bad injectors. I could really use any constructive advice
