okay guys, time to put your thinking cap on!
Here is the info: 95 d16z6 turbocharged swapped into 97 ek hatch running obd1.
Car was up and running for months till the other day, just stalled and wouldnt start up.
threw code for camshaft sensor, replaced distributor, rotor and cap, code gone but still no start, did the checks according to manuals, everything points to a bad ecu, so ordered a ecu for it, still nothing...

heres the part that i dont get, i used a 95 accord ecu and the car starts right up! ive also tested my two chipped ecus in a different car and both work, just wont work in my civic.

ive checked compression, spark, fuel, air, its got it all... timing is dead on too!

at this point im stumped! the accord ecu will start my car everytime, but the two chipped ecu will not start my car, it tries to but dies seconds after it fires

anyone have any ideas id love to hear it! thanks.

And never says exactly what ECU is in the car and have been in the car. Chipped as in basemapped? eBay? What was the code exactly!

ynos

Sorry, the chipped ecu is a p28 dyno tuned on chrome, the other chipped ecu is a p06 same map on chrome, the accord ecu is stock. The p28 was the original one that was in the car. I forget the code number but after the dizzy swap the code is gone.

Are the plug wires installed in the wrong firing order on the cap?

Getting spark? What color? Getting fuel? What's the pressure? OEM distributor?
There is a link in the FAQ on how to diagnose a no-start condition.

ynos

Yes getting spark, white, its getting fuel 40-45 psi, dizzy is reman, tried two brand new ones, thing is why can i start the car everytime with the oem accord ecu, but cant run my chipped ecu? But ive tested both ecus in a different car and they both work!

ynos

Nope, installed correctly... it will start with the accord ecu, not with the chipped ecus

If you still have the old distributor put it on and see if it starts with the chipped ecu.

ynos

The old dizzy was a reman one that was returned as a core. Ive also returned the new core and gottend a new reman dizzy, same results each time, accord ecu will start the car up with no hicups, while the two chipped ecu for the motor will not fire.

when you put the new ecu in did you pull the chip from the old ecu and put it in the new ecu? wouldn't be the first time a chrome .bin deleted or corrupted itself.

if that was what you did try to Raeburn the .bin and see if that helps.

you said timing is dead on. did you recheck or assuming since it was good, check that it didn't jump timing. .

check all the grounds....especially the thermostat ground.

check fuses both under dash and under hood

check main relay

ynos

Nope didn't pull the chip out, ive tested it in a different car and both chipped ecu works, ive tripple checked timing even went as far as taking it off and redoing it, its dead on! Ive removed and cleaned all grounds, still nothing, all fuses good so is relay, the thing i dont get is why is the accord ecu the only one that will start the car? The chipped ecus are good because ive ran them both in a different car.

Saying "Accord ECU" doesn't tell us anything.

ynos

Its a 95 accord ex oem ecu, it will start the car fine, but i cant figure out why my two chipped ecu thats been tested good in other car wont start my car which was the original chip for the motor. I have checked everything and it just dont make sense to me.

Does the Accord ECU have the same firing order as the Civic ECU?

ynos

Yes same firing order

I'm not too sure about that.

ynos

I am sure its same 1-3-4-2, the accord engine picture you have is obd2 f22b non vtec with external coil, i have the obd1 f22b1 vtec internal coil, non vtec #1 starts on the front, vtec #1 starts on rear like the z6

I also have diagrams for each and you never said what ECU this thing came off of. This is information you might wanna mention up front. So a virgin OBD1 Accord ECU can start it but your "chipped" ECUs cannot. Good luck to you.

Do the injectors spray fuel? Does the engine start with starting fluid?

Post pictures of your plug wire firing order and your mechanical timing.

ynos

Im sure the injectors spray because the car will run with the oem accord ecu.

Ill take pictures when i have time.

ynos

Yup im sol lol, i didnt have a extra ecu at the time, just the accord ecu, thats why i tried it and it starts it! Weird weird weird.

Former User

In my opinion, you are over-interpreting the results with the Accord ECU.

You need to pinpoint the problem associated with ECUs that will actually be used for the car.

The more No-Start Diagnosis 101 information that you're willing to post, the faster you're likely to pinpoint the problem.
