Re: No MIL at start up
Welcome to the garage.
You can do the instrument self test to see if it will come on then: with ignition in OFF, push the odometer reset knob and while pressing, switch the ignition to RUN. Now the selftest will start and all indicator lights must come on. (also all instruments will go to full scale and return to normal indication and odometer will count 111111, 22222222 etc). As soon as the test starts, you can release the reset knob. If it still doesn´t come on, i would check again if the new bulb is ok. If it is, then most probably the problem is with the instrument cluster circuit board.
There are two fuses for the instrument cluster (#17 and #22 on the junction block under the steering wheel area), but probably none of the instrument warning lights would work with one of them blown.
