The ecu relay, which is the ignition relay (I’ve found out) is working fine. I haven’t checked for the 5v reference yet

It’s not the scan tool. It’s the truck

Anyone know what relay or fuse controls the ignition coils?
Also, my scan tool won’t communicate with the truck.

I see the other kind has the ECM and Starter relays identified but the one for mine doesn’t say. It does show me the ignition relay. But that’s all.
And these things are very aggravating to even get out. For example, I can’t. I cannot get the damn relays out. Why would they design them that way

So I removed the radiator cap and ran the engine parked on an incline (my driveway) for what seemed like a long time. The coolant kept bubbling and bubbling. I guess this is the burp method. Anyway after about 15-20 minutes of this, the cooling fan came on!
I suppose enough air escaped to let everything do it’s job? I’m not sure how that works.
I took that as a success and shut the car off. I’ll know after I take it for a spin if it’s fixed. The coolant was still burping, however. I’m not sure if I should continue that until it stops.

Good call on the air in the system, Eric. Thanks.

Haven’t had much time to look at it lately, but I did notice that the condenser fan also does not run at all when I turn the a/c on (which i’m sure has no refrigerant in it) not sure if that matters. I just wanted to say that, as it might alter your idea on what to look at.

I’ll check the temperature sensor, thanks.

Eric, I’m not sure what to look for when you say fan timer. Keep in mind, everything I know about cars is learned on youtube.

Meantime I’ll check for air in the system.
Thanks for the responses.
I’ll keep you posted.
