Hey all I had a question maybe some of ya can give me some input on. So I've got an 89 k5 w/TBI problem is that it's hard starting. Doesn't matter if it is hot or cold still gotta crank it a few times to start her up. Brand new battery and starter. I'm thinking it's just a loss of fuel pressure or a bad sensor. Any ideas the most likely culprit as far as which sensor? Thx.
