I Need Some Info/Help Please

im thinking about buying a 1990 1500 Cheyenne V6 5spd. tomorrow, is it the same thing as the 1500 silverado? other than the front clip is there any difference? if i buy parts do i buy for a silverado? i was looking on summite and there wasnt anything for this truck, but there was ALOT for the silverado.. the guy said it was carburated and need's the injector's cleaned, so it has problems starting, would it be hard to convert it to a fuel injected lt1/6spd? is there a kit? sorry about all the question's, i just want to know all i can about it before i buy it.. THANK'S

The drivetrain (engine, tranny, diffs) are the same for both chevy and gmc in 1990 .(I have a 90 GMC K1500 that I have owned since new). The v6 engine is fuel injected already. Hard starting could be a dist issue, sensor (temp), EGR or fuel (pressure, bad injector).

A fuel pressure test and hooking up a scanner may help determine the hard starting issue.
