engine light will not come on when key is turned on. everything else works

It would not on old one, Just replaced pcm and still no light, have not taken it to check for connection. All other lights and gauges work, just replaced cluster as well

Have *ALL* of the fuses been *TESTED* using a test light - with the key on? .. [That's ALL FUSES!]

All fuses under hood will volt meter. Should the fuses in the fuse box on can be checked

EACH AND EVERY FUSE on the vehicle needs to be TESTED! https://www.youtube.com/watch?v=ksrsXwwukFc Testing takes about 4 minutes!

All check good, what about relays

Will the engine start and run?

Yes, I have no issues except this light, need it for North Carolina inspection. I did have 5 fuses with no power, numbers 4,7,8,24,28. Pulled fuse and no power on plug either

Then relays are working! .. You need a wiring schematic of the check engine light circuit .. That circuit is open > SOMEWHERE!

Where do I find that

Find a shop that 'might' look it up for you on Alldata .. Now for a fee, 'you' can get it from alldatadiy.com .. That will include all the diagnostic & repair information that you will ever need! .. I don't know your skill level but I think you would certainly benefit from the subscription.. I hope you have good luck with it!

thanks for your help. have a great day

Likewise!
