I've never used a store bought tester on obd1. I usually use a jumper wire between the A & B terminals at the aldl, key on, check engine lites goes to flashing, you count the flashes to get the codes, your looking for two digit codes. I'm not saying that is the best way.
Voltage to check engine lite goes hot with the key on, gage fuse protected. The ecm grounds the service engine soon lamp.

Most catastrophic may be a Head gasket leak. Check coolant tank for bubbles with the cap off and engine running. Otherwise, last time serviced? Did you check oil? There is a trouble code system, but need a service manual to read the code.

Check engine lite

Your vehicle’s computer system has self-testing capability. When the computer senses that there is a problem with one of the components or sensors it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem and you should have the car diagnosed and repaired. First step is to find out what code turned the light on.

98 C1500 Silverado ''service engine soon'' light

the service engine soon lite comes on due to an input sensor to your vehicles computer that has gone out of its parameters. this lite does not come on due to mileage. the computer needs to be scanned for code #'s in order to diagnose correctly. autozone will scan codes for free. if you get me the code #, ill try to assist further, otherwise you may want to see your local garage.
