98 f150 obd2 ?

[alwaysFlOoReD]

I have my old 98 f150 4.6l that lost a cylinder last fall. Its been parked all winter. Put in a fresh battery and it started right up, still on 7 cylinders. I hooked up my obd2 reader and with key on it could find the type of truck and engine etc. When doing a koeo it didn't complete. IIRC because of no link. When I did a koer same, no connection. I would input the truck info and as soon as I turn the key to start the reader would go black and after the engine got running I couldn't get or input any info.
I'm don't have any experience using these code readers. Am I doing something wrong? Did I follow the instructions wrong?

Hmmm... Had trouble with my 97 F150 a while back. Bought a new reader but haven't really tried it yet to see if new reader would connect.

If the plug fits its obd2...

Obd2 started in 95 for ford except HD trucks. 96 for everything in america. The obd2 port has a fuse and if its blown obviously you wont get any data so that's where I'd start.

I was not aware the port has a fuse. Nice to know.

Everything should be fused.

I will check but I'm getting some info with just key on but not running. As soon as I start the engine running the reader doesn't read. Maybe the port shuts power down and the reader loses its place?

Try connecting it while the engine is already running? I think my one scanner will exit when going from run to start.

Will do. Thanks.

On your '11 Ranger, OBD port is on the same fuse as cigarette lighter.
