Where is the ECM located on a 92 S10 - Cars & Trucks

what transmission, here. automatic or manual stick shift?
S10 not blazer S10

old cars this old (pre digital documents) are hard to find and when found are not complete. or poor .
A/T box?
the PRNDL switch must be good. and cranks in both Park and neutral.
yes the relay clicks too, if not the PRNDL is prime bad part.
there is fuse named CRANK.(1st inline here)
the starter can be hot wired (a test) to prove starter work.
if stick shift TRANNY it is called the clutch switch. to crank,
some books say hood up fire wall, center is relay. IDK


see why we ASK transmission first/
if the relay does not click the fuse crank blown
or PRNDL is dead only on P mode, try N.
if stick shift,, clutch CCP switch bad or just mal-adjusted.
ST below goes to the relay then to starter solenoid
the relay colors are there. Green or Purple.

PRNDL is on side of TANNY part of shift linkage.

Question heavily edited for clarity and typos.
Question moved from Smart for Two, to Chevy S10.

This could be a job that goes like a dream, or it could be a 2 week snagging job to get it to run right, or even run at all. They are both 4.3 and fuel injected so that's good.

You will need the ECM from the vehicle the engine came from, and it may need reprogramming.

Where is the engine, or where is the manual transmission?

The ecm A and B fuses are located in the underhood fuse/relay panel

Service engine light may be wanting you to simply change the oil and reset the code.
You don't need to locate the ECM (what would you do if you found it???)

I'm not 100% positive about a 1992 Toronado, but on my 1986 Toronado the BCM is behind and to the upper left of the glove box, and the ECM is behind the right side kick panel in front of the door. GM had a habit of moving them around from year to year.

Poss defective engine wiring harness or injector or ECM.

The 1992 Plymouth Truck Voyager 4WD 3.3L MFI 6cyl the Engine Control Computer is located under hood, driver side, front side of strut tower, rear of headlight, mounted on inner fenderwell .

Hope this helps (remember to rate this answer).

It should be a plug and play if your using the ECM for the 1994 engine. The ECM on the 1996 S10 will no work on the LT1 engine, for one thing the S10 ECM will only command for 6 fuel injectors and will have different injection pulse and so on. The program of the S10 ECM is made for the Vortec as to the LT1 will have different parameter **** as engine running temperature, vacuum readings, and timing.
The most obvious would be the 1994 LT1 runs on a OBDI system and the 1996 is running on a OBDII system. You can still run the 1994 LT1 from a 1994 with a OBDii system ecm, but some of the sensors will need to be upgraded to accommodate for the proper readings the OBDII system will need to have the engine to run right.
If you don't have the right ECM for the LT1, go to the wrecker's and locate one, Caprice, Camero, Firebird ECT.....
Thank you for using fixya and good luck on your project.

the left kick panel by the clutch under the plastic. its a silver box.
