starting problems

i own a 1988 4.3 V6 chevy S10 Blazer. sometimes she starts up after she turns over about 30 times, but now she just turns over. When shes running her exhaust blackens the ground. Can anyone tell what could her problem be. You can email me at [email protected].

Sorry I don't believe in e-mailing you the answer when someone else might need it.

Just a guess but I think that it's your fuel pressure regulator.
A shop should be able to test this.

Could also be bad fuel.

Someone else will probably have a better idea than me.

my 2.2 did the same thing, w/o the soot. now it wont start at all. see my thread (no start condition) for more info.
