SOURCE: Where is the headlight relay located on a 97 chevy

It is on the left side of the steering column, below the instrument panel. It is easiest to open the driver's door, then lie on the floor and look up under the dash with a flashlight.

My 1988 chevy k1500 700r4 will not shift out of first

check to see if the vacuum line is hooked up to the modulator,(on the trans. next to the pan u will see a steel line with a vacuum hose on the end.
Make sure it has vacuum when running also ,if everything is ok,pull the hose off the modulator ,if any fluid comes out ,it's bad
Also if the governer gear stripps out ,same problem,under the round cover on the tailshaft,with a wire bail safty clip usually, just pop the wire clip pull the assembly out and look at the PLASTIC gear on the end ,if it is "applecored " it's the culprit.

97 chevy 4.3 liter no spark no fuel pump running.

4.3 and 2.8 motors have a ceramic module in the distributor. if you have alot of miles on the truck, and there is no spark, that module is usually the culprit. easy to replace with a nut driver and some dielectric grease. mod is located in the distributor when you take the cap off look straight dowm and its right there.
also check eec relay and fuse. that will also cause the prob.
