I have a 1992 honda civic the car don't start it crank when I turn the key to the ignition not start I hear the click and the engine light stay on the code the engine light right is 19 { auto tanny lock up } it a 5 speed I test the map sensor and I get 5.4 volt there no spark I change the whole distributor and still no spark I am thinking maybe a bad ecm but I don't want to spend $150 on a use part I don't need so what would be the next step should I take in find out why this car would not start is there any way I can test the ecm.

Run through the tests, outlined in Sections A and B, below:

I have run ture the a and be test and the map sensor is reading a 5.4 volt do I still need to do a confirming test on the ecm would I have the same result ?

Skip the confirming test.

OK so what the next step does this mean the ecm is good

Yes. Does the CEL come on and go off after 2 seconds, when the ignition switch is turned to ON? Do you hear the fuel pump run, during this period?

Check Engine Light (CEL) Tests. If the CEL does not go out, most Civics will not spark and the fuel pump will not run. Therefore, all efforts should first be directed to correcting the problem(s) that prevent you from being able to answer "Yes" to the three basic diagnostic questions below:

a. Turning the ignition switch to ON (or position II), not START, does the CEL come on and then go off after 2 seconds? If not, the problem is with the ACG (ALT) (S) 15 amp fuse, in the under-dash fuse/relay box; ECM (perform the K-Test); Main Relay; or the Ignition Switch. Perform tests in that order.

b. When the CEL goes out, do you hear and/or feel the Main Relay "click"? If not, repair or replace the Main Relay.

c. During the 2 second interval that the CEL is on, do you hear the fuel pump in the gas tank run? If not, check that the fuel pump works by jumping terminals 5 and 7 on the main relay connector and then turning the ignition switch to ON.

Be sure to test all under-dash and under-hood fuses with a test light or multimeter. Here's how:

I have tested all the fuses and all are good the cel stay on when I jump it read code 19 a/t tranny lock up and it a 5 speed and like I said I test the map sensor and it give me 5.4 volt so what else do I need to do or check to get the cel to come off since you said most civic would not spark or fuel pump I have buy this car at a auction and when I got it had no ecm I buy a use one which came out of a automatic tranny car does this matter

I believe your problem is that the ECM is not compatible. You installed an ECM for an automatic, not a manual, transmission. It makes a BIG difference! That's why you get a Code 19, which is not even applicable to your car.

Yes it stay on that why I jump it to read the code and it give me a code 19 which is a/t tranny lock up something like that and it a 5 speed could it be it and ecm for and automation tranny car that why the lite stay on I did think it would matter

Is your Civic a DX, LX, or EX? What engine do you have?

It and lx on the engine size I am not sure where would I find that info it not on the door and it not understand the hood and I don't see it any where on the engine it and 1.5 or a 1.6

OK it and lx 1.5L L4 FI 1992 honda civic 149000 miles on it

You likely need an ECM with OEM part #37820-P06-A00, A01:

While we find your parts, please enter your ZIP Code at PartsAmerica.com

You might be able to find an inexpensive ECM on Ebay or at a local salvage yard. Carefully check the part number out. You may even want to call your local Honda parts department to verify the correct part number.

So it the wrong ecm it came out of a automation civic

Yes, I think you have the wrong ECM--it will never work in your Civic.

OK I will buy one and see if that work hopefully it would I buy a use one maybe on eBay should the car atlest start up even if the only diff is the tranny

If you buy the proper ECM, the CEL should go out, after 2 seconds, and the car should start. The ECM that you have now will never work in your car--try and sell it.

OK I have replace the ecm and the cel go out the car start still don't start it crank any idea what the problem I replace the whole distributer same problem as before would not start

. Do you hear the fuel pump run, when the ignition switch is turned to ON?

. Is it the correct ECM for your car?

. Do you have spark?

. Have you cleaned the main ECM ground on the thermostat housing?

I hear a hhhhhh for a sec and then it stop I would think that would be it what do I do next to get this car going any idea I appreciate you taken the time in help me thank you
