yo,
the Check Engine Light (CEL) comes on when the electronic engine control system is not working properly. The check engine warning indicator comes on briefly when the ignition switch lock cylinder is turned to ON, and should turn off when the engine starts. If the check engine warning indicator does not come on when the ignition switch lock cylinder is turned to ON or if it comes on while the vehicle is moving, the system is malfunctioning
If the CEL does not light up at all when starting it; then suspect that someone removed it
Is CEL LIT Continuously?
Same for the Transmission Control Indicator Light (TCIL) (Overdrive off/on) Switch/LED - on en of shifter stalk
Is it blinking?
Try a DIY test too; Self Test for Diagnostic Trouble Codes (DTC)s by my pal, BroncoJoe19

ensure that the engine temperature must be greater than 50° F for the Key On Engine Off (KOEO) Self-Test and greater than 180° F for the Key On Engine Running (KOER) Self-Test.
Run it around to heat the engine up and shift thru all gears incl Reverse. Then turn off all accessories/lights, etc.
Make sure A/C is off and transmission is in Park (automatic) or in Neutral for a Manual & release clutch.
Do Key On Engine Off (KOEO) portion first.
Look Codes up in my broncolinks.com site using the new Search function.
And Post em here according to:

Possibilities w/NO CODES:
Engine Stall During Transmission Engagement TSB 97-24-23 Bronco, 96-97 Vans & F Series, 97 Expedition, 98 Navigator, 96-97 F-53 Motorhome;
Some vehicles may stall when the transmission is placed into gear. This may be caused by the transmission fluid filter becoming detached and/or loose.
Install a new design fluid filter and seal assembly. The new design has legs molded into the plastic filter cover (Figure 1). This new design filter does not require using the rectangular transmission pan magnet.
Follow all the normal diagnostic procedures outlined in the appropriate model/year Service Manual. Repair as required. If all normal diagnostics fail to correct the problem, refer to the collowing Steps.
Remove the transmission fluid pan to determine if the transmission fluid filter has dropped down or is not firmly seated in the pump bore.
If the filter has dropped down into the pan, discard the filter assembly and remove the filter seal from the pump bore.
CAUTION: BE CAREFUL NOT TO SCRATCH OR DAMAGE THE PUMP BORE WHEN REMOVING THE SEAL.
NOTE: DO NOT REMOVE THE ORIGINAL FLUID PAN MAGNET FROM THE FLUID PAN OTHER THAN TO CLEAN AND REINSTALL.
Install a new Filter and Seal Assembly (F6TZ-7A098-AB: 4X2, F6TZ-7A098-BB: 4X4). Refer to Figure 1.
CAUTION: DO NOT USE THE RECTANGULAR TRANSMISSION PAN MAGNET WHEN USING EITHER OF THESE NEW DESIGN FILTER AND SEAL ASSEMBLIES.
CAUTION: DO NOT REPLACE A REUSABLE PAN GASKET WITH A CORK GASKET, THIS MAY RESULT IN A TRANSMISSION FLUID LEAK. CLEAN AND REUSE UNLESS DAMAGED. REPLACE CORK GASKET WITH CORK GASKETS.
Refill transmission as required using MERCON® Multipurpose Automatic Transmission Fluid (ATF) (XT-2-QDX).
