Hey guys,
I have a '96 S10 pickup, 4.3, 5 spd, CSFI, 120,000 miles. Its starting problem has been getting worse recently. At first it would have trouble starting, and I would have to crank it for several minutes at a time before it would catch. Once it is running it does fine. The times when it has trouble starting have now outnumbered the times when it's fine, but every now and then it'll start right up no problem. I have replaced the fuel filter and done all the usual tune-up stuff. Any suggestions?
