Hello, I have a 95 astro v6 vortec engine 2wd auto trans. My speedometer started going crazy. It would say I was going 70 mph while sitting still. Odometer was also turning while in park. When I tried to drive the vehicle it acted as if it was stuck in second gear and wouldn't shift. I did a little research and decided it was the speed sensor on the transmission. I purchased one and my brother in law put in on the van for me. It shifted OK after the replacement but the speedometer was still acting up a little. My wife suggested unhooking the battery to reset the computer... so I did. After getting it back together and taking it for a test run, the speedometer was working great again and it was shifting good but about a mile down the road it just shut down... died completely. It started right back up and then ran great for about a month. On the way home from work one night it just died again. Headlights went out, engine died and I had no interior lights either. Radio light would come on and the power windows would work but it wouldn't start when I turned it over. I had it towed to my sons house and since then it did start and run with lights working and all for about 30 seconds but it died again. Now it won't start again...no lights either. Fuel pump doesn't seem to be getting power as well. I am lost here!! I tried to remove the new speed sensor and replace it with the old to see if it would start but I couldn't get the new one out. It is in there really tight and won't budge. My brother in law doesn't seem to think it is the sensor... says that won't keep it from starting. Does anyone have a clue what could be wrong or even where I should start looking. Any help would be greatly appreciated!!!
