I'm trying to help out my neighbor who has this problem.
It's a '94 Chevy Blazer 4-dr. with about 99k on the clock. He has a hard time starting it up. It takes him about 4-5 attempts before it'll turn-over and when it does finally startup, it idles rough. It sounds as if the idle fluctuates high and low. He says the only item that's been changed so far is the fuel pump.
What should I look at next????
A) Suggest a tune-up (plugs, wires, cap & rotor, air filter)
B) Check electrical system (battery, alternator, starter)
C) Fuel system (filter, injectors)
Thanks in advance
