94 TBI 8v Tracker , no start. (what tranny?)
expediency.? The CEL is important be we can work the ECU backwards, here is how: This is the fast track way, no pun.
see Scotty do that here.
see him do the spark test and test fuel test.

btw , if the ecu is not injecting here are the reasons. DTC are the flashing CEL codes... Morse code like. this is why the CEL must work !
1: DTC code 41 spark failure. real or ECU cant see it ! if the tachometer is dead, so can this be dead.
2: DTC code 42 CMP failure.
3: TPS stuck at wide open throttle "WOT" error, (bad ground to TPS causes that easy
If above is OK, then the NOID light test passes, if true, then below is bad.
4: no fuel pressure. 30PSI is normal , regardless of pump buzz,etc. ( sure the fuel filter is good... if packed the pressure rises, at rear test port.)
5: a clogged injector.(good NOID, good pressure 30psi, is the coil in the injector open , that is, no longer 1 ohm?)

- if the engine is good, has great compression? at 150PSI, many are not, the belt or keys have slipped , ever set the crank bolt to 94psi yet,? per the factory TSB?
- and a timing light shows good spark to the #1 near 8 degrees BTDC? (yes the light works cranking too. 8 degr. is to the left on 0 on the scale, if off, the belt slipped. or others reasons.
- if all that works, then test fuel works , and for sure if dry test below fails.... does it run on test fuel?
- you can also lift the top of the TB air horn and look down there, and see the single injector , inject while cranking.? does it inject?
- if there are no injections , the ECU may be stopping this or there is no fuel pressure, 3 or 4 more tests. but the test fuel , test of a day engine, is a great test
