Default non C4 problem

My DD 91 Blazer lately has been harder to start and idle. I just did a tune-up a few months ago and it was running fine. After thinking about all the posts I have read about Vettes and the problems we have with them I went though them in my mind and decided to check the PCV valve. Not only was that plugged solid but the hose also all the way to the TB. . I guess I am spending too much time on the Vette and Kathy's Cavalier. :o

As a long time s10 owner....2 words....fuel pump. I had mine out twice today. I have been having starting problems for months and I rigged a 2001 pickup truck pump to fit my 98 jimmy. I refuse to pay the extortion that they charge for a new pump. I found a low mileage AC Delco pump on craigslist for 25 bucks. The cheap ones that last a year are 200 bucks online, a Delco unit is close to 300.00. My Vette pump was only 65 bucks.

if it starts good cold but is hard to start hot, idle not steady when hot, put a new ignition module in the distrib...more 'symptoms' would help.
