Hi, I have a 1990 gmc sierra 1500 with a 350 engine and I decided to do a tune up on it by myself. It ran fine before I changed the spark plugs and when I changed the spark plugs it takes about 5 cranks to turn the engine over and sometimes it wont even start now. I thought it was the wires running from the distributor and I changed them and it started right up after that. But the strange thing is that after I start it up it runs fine, I shut it off and it starts right back up again. The only thing is that it starts really hard the first time I try to start it. Any suggestions?
