Its in the fuse box.
ECM (ECU) can have up to 4 or 5 fuses.
2 for ECU, 1 for injectors,, one more for fuel pump, and 1 more for spark. (varies by maker and years, end engine options)
the operators guide will not be clear on this, at all.
but the FSM is dead nutz accurate. per engine.
or
alldata.com

is the CEL lamp dead, i the cluster>? this is the first sign of no power to the ECU.(ECM)

why not post symptoms and we can take you to what ever it really is....
or test all fuses if not sure which is which(its complex this wiring!!)
ok, i looked for you.
the engine bay box.
Injectors
ROOM (memory of ecu)\
ENGine , fuse is engine. EFI
HEGO is the EFI oxy sensor heater fuse.

spark power comes from the ignition switch ON. lug
and that can only go dead (ECU good) by blowing the 100amp main fuse, that kills all. things.

did you lose spark (do tell?)

SOURCE: serpentine belt for 1998 mercury tracer

Hey there MSM,

  • Get a 14mm or 9/16" socket and a long handled ratchet or breaker bar.
  • Get the belt around all the pulleys except the A/C compressor or Alternator. The routing diagram is on one of the radiator supports.
  • The tensioner pulley is near the Alternator toward the center of the engine. It's on a spring loaded arm. Get your socket on the center nut of this pulley.
  • Slowly pull the ratchet toward the center of the engine. The pulley will pivot on the arm allowing you to get the belt on the final pulley.
  • Slowly release the tension.
  • You're done
Mike

SOURCE: where is ecm box located on 99 tracer mercury

It is located under the dash, directly in front of the center floor console. The easiest way to access is to remove the console, which is very easy to figure out and do. The console is only held in place with about 6 phillips head screws

94 mercury sable stuck in park


Check your brake lights. If they dont work, the shifter will not come out of park. You should be able to turn key on, move shifter, then start it in neutral. Check fuses and then brake light switch.

94,merc tracer wont go into reverse


this is an electric tranny. when they stop going in gears it means the transmission is failing mechanicly. check fluid level, and smell it. if it smells burnt or looks very dark its prob on its way to be rebuilt. good luck.
