okey so i have a 94 chevy astro van with 210k and its a v6. im having trouble starting it, the enigine will turn over and crank but it will take me about 5 turn over to get it going. ill drive it to work which is like 5 miles away and when i leave 6 hours later i have trouble to start it again. (most of the time in the morning it will start the first time.) note that im in nevada and the weather is in the 100s. it seems to me that stepping on the accelerator a bit helps to get it started. after i get it going i have no problems. any suggestions.....thank yu.
