Use of a engine troubleshoot diagnostic device

Innova sells a scanner that runs on OBD1 cars, but that's only needed on 1995 and older non-CARB (California) cars—1996 and up are OBDII. That scanner should be fine, but may not pick up OEM codes. Yours will work but only to pull the generic codes. Even old GM vehicles had OEM codes that some scanners do not pick up so keep that in mind.

You have a few options here for OEM codes that but none are cheap: The one I have for bi scanning and testing is the Innova 5610 but if you do not want or need it and want to avoid the cost, the 5410 is similar, but lacks bi control.

I bought the 5610 because I don't need the OBD1 option it has right now, but it's there with the adapters—I just have to buy them separately and can't get them as a bundle like you get with the 5412. I picked that one because I replaced an EOL 6100p I bought unaware, and got a major discount with bidirectional control. I consider the other scanner a $108 mistake that I can still use after the massive discount I got through their trade-in program.

If you want a tablet scanner, I like the Xtool scanners, but they are pricey compared to even the Innova scanners I mentioned before. If you want one, look at Xtool or OTOFIX, but you will pay a lot more for them.

That said, before scanning it for codes, it could be something like a worn battery. I would see if you can get a cheap battery tester from an auto parts store or a big box store like Walmart and start there. A lot of these newer batteries aren't built as well and will only last 2-3 years, 3-4 if you get an expensive one, outside of super expensive ones like Optima and the AGM batteries. Start there and work your way up. The other thing you can do (if it's easily accessible) is find the starter and whack it with a rubber mallet and see if it starts when you do that, if you do not see any corrosion on the grounding points which can cause the same issue. If it does, you need a new starter.
