Customer Question

Got a 1994 Nissan d21 xe 2.4 ka 4cyl. 5 speed. Was running perfect and just died in traffic. No spark and no fuel. Replaced a good ecm box and checked all fuses and relays. Noticed that check engine light doesn't come on anymore when I put the ignition key on run position. That's the one to turn on the fuel pump.

Hello my name is ***** ***** thank you for your question.

Did you check all fuses with a test light?

Customer: replied 8 months ago.
One side has power and the other not
Expert:  Jay replied 8 months ago.

What do you mean?

One one side of the fuses have power?

Do you know how to use a Test light to check fuses?

Customer: replied 8 months ago.
Fuse block, sorry
Customer: replied 8 months ago.
Power across fuses is good

When you are checking fuses with a test light, you leave the fuses in place and probe the back of the fuse. The fuse has two openings in the back open for testing.

So please double check all fuses for me and if you find one fuse only has power on one side, that fuse is blown and will need to be replaced.

Please double check and let me know. I can keep this question open while you do

All fuses are good, noticed the ecm diagnostic lights in the box don't come on at all
Customer: replied 8 months ago.
Also ignition relays #1 and #2 are clicking when I turn the key for accessory and run position
Expert:  Jay replied 8 months ago.

Then you will need to perform a Ecm pin test.

Do you have a Volt Meter? how good are you at electrical?

Customer: replied 8 months ago.
I'm pretty good. Got a fluke 12v meter
Expert:  Jay replied 8 months ago.

Hang on then and let me get you that information

The plug on my ecm is blue. PE Mecm -T113 sticker on it
Expert:  Jay replied 8 months ago.

That is the complete Ecm Terminal layout of your 94 2.4 Truck

Expert:  Jay replied 8 months ago.

Since the truck does not run, skip the steps that say engine running. You want to perform the Key ON steps.

The image of the Ecm at the end is the back side of the connector where the wires go into it.

Do you have any more questions on this?

Customer: replied 8 months ago.
I'm going to check them and get back with you. Going to take some time
Expert:  Jay replied 8 months ago.

That is not a factory sticker. That looks like a After Market inventory type sticker

Expert:  Jay replied 8 months ago.

The second one is the factory sticker

Sure let me know what you find.

I have company today. So I may not be online till later tonight or tomorrow morning.

Ecm voltage test was all in the parameters in the key on position. What do I check now?
Expert:  Jay replied 8 months ago.
If all Ecm voltages are good, the you want to check the ground circuit. If that is good, the the Ecm is bad

Customer: replied 8 months ago.
Checked and cleaned all grounds and nothing. Why doesn't the check engine light come on when I turn the key on? I know the fuel pump used to come on for a few seconds.
Customer: replied 8 months ago.
How do you bypass/jump the ecm relay and the fuel pump relay on the passenger side engine bay wheel well?
Customer: replied 8 months ago.
How do check the relays to see if they are good or bad?
Customer: replied 8 months ago.
Also, can you tell me how to check the check engine circuit? I'm thinking it has to do with that.
Expert:  Jay replied 8 months ago.
What I provided you is checking the engine circuit
