I got some codes
96 High speed fuel pump relay circuit open.
85 Problem with the CANP, a rich condition causing the ECM to hit its lean limit.
24 Bad ACT/VAT sensor, on EDIS systems coil 1 bad
21 ECT bad, engine not warmed up, bad thermostat, low coolant
I'm not really sure what the first one is telling me. Is this a bad relay like you guys said and if so which one is it. These things are kind of spendy at $35 a piece. I did pull my fuel relay and have it in front of me. Not sure what I am looking for though.

I am not sure what year truck you have I assume it is a 95 and up.
The Haynes manual has some neat electrical checks you can perform on the relays, sensors and such. a $15 book and a voltmeter/ohmmeter can save you lots more. Helps eliminate the good from the bad
