My check engine light is on and i want to get it fixed before i smog the car they will fail the test as soon as they see the check engine light without even testing i think the MAF is not connected? any reason why the owner before my have took it off? the engine has some wires that are taped together maybe engine swap? any ideas?

 

To run without the MAF it's needs a MAP sensor and the ecm programming to match. I think I saw the MAP in the picture but I'm not sure.

 

well your MAF power relay is in the wrong spot (not that it matters) and he obviously broke the tab that holds the harness to it, and you're missing a MAF burn-off relay. part numbers for an '87 are 10067925 for a MAF power and the updated part number for the burn-off relay is 10094701.

your car should be throwing a code 33. what codes is it throwing?

 

how do i check the codes? i did a search and found this link but it does not work?

ok found the link here https://www.thirdgen.org/service-eng...ht-error-codes couple of questions where do i find the 12 pin DLC connector and also it says "Run a wire/hairpin from Pin 6 to Pin 12 with the ignition off (although on later cars it should be from Pin 5 to Pin 6)" define later cars? what year?

 

anyone?

 

The diagonstic connector is usually under the dash on the left or right side near the steering column. count the pin holes from left to right, 6 and 12 should be on the far right.
You need the chart/instructions to read the flashing lights.
I think it flashes 3x three seperate times before the codes start.
Count the flashing lights code 25 would be 2 flashes pause then 5 flashes then it flashes the next code if there is one, then repeats flashing the codes only.
ALL Vehicle wiring is a nightmare. Take your time and try not to get too frustrated. A good manual is a ton of help.

 

thank you!!!

 

ALCL, or ALDL connector pin out. Jumper Diagnostic Terminal (A) to Ground (B) to flash the codes.

"that was easy" LOL i got code 33 in pic 1 you can see the connector is not plugged into the relay p/n 10067925 any resaon anyone thinks its not plugged in? should i try to plug it in i just dont want to short anything out. then this should clear my check engine light right?

 

Plug it in and see what happens. You shouldn't short anything out. The missing relay will give you the check engine light. Put a relay in and start the car. Check Engine light should go out unless there is a wiring issue.

 

In your pictures the Fuel Pump relay is laying behind the brake booster.
The MAF burn-off relay is where the Fuel Pump relay should be, but isn't connected.

This thread has a picture posted by MikeInAZ of proper location of relays mounted on the bracket. This is on a T/A thus the driving lamp relay.
