Re: HELP...1986 C20 5.7....smog removed,,,Check engine light???

I'll get prettier pics this weekend if you want,but the 85 tbi etc was all matching my 87 that i had.I've only since finding this site i've explored rpo's and vin #s,and yes as you say it shouldn't be(just read to do it u have to shave bolts and other stuff?)........So when i turn the key i shouldn't hear the fuel pump humpin,before startin, should be manual pump?And no wires in there either.hmmmm
