Chevrolet Repair: 1993 S-10 Blazer, addvice, fuel pump

Question
    Hello, i have owned my 93 S-10 Blazer since 98 and just recently i have been having trouble with it starting and it's kind of got me frustrated. I've changed just about everything that i can think of that has to do with the ingnition system. It has the V6 4.3L Vortec engine, the vin is w. Everyone always asks.
    Anyway any addvice that you could give me would be great.

Answer
Hi Eric, What you to do is find out if it is a fuel or spark problem. To check to see if it is a fuel problem spray carb cleaner into the intake and see if it fires up quickly. If it does then the problem is either the fuel pump or the CPI injector.

          Let me know what you find          Mark
