Hello, I have a 96 blazer and its got 203k ran and drove llike a champ till 3 days ago. I went to go pick up my girlfriend and i shut it off for 5 minutes and went to go start it again and it was turning over but not starting. I was lookin for things wrong and i couldnt figure it out and went to start it and bam started up but it was rough. Drove it home no problem shut it off again tried to restart and it wouldnt start at all. Had a very strong gas odor coming from the back. Let it sit a couple hours got it running 3 times and the 4th time it wouldnt start. But i did notice on the 3 times the rpms were running higher than should be. Not throwing any check engine light codes. Can anyone help me out?? starter new,cap,rotor,plugs,wires,and fuel pump new. Please let me know while i have 3 days off! Thanks
