I have a problem with keeping it running, i wired the fuel pump to run constantly, motor runs strong for 1 to 2 seconds then dies, i pulled another computer and wiring harness from a 89 rs automatic does the same thing runs then dies, but it starts every time. I have replaced everything but the distributor and the exhaust cam sensor. the previous ecu and wiring from the 5 speed had a shorted fan relay, computer threw code 20 for electrical load, replaced with different wiring and ecu from auto gives code 19 for lock up control solenoid valve(automatic transaxle vehicals only) is it possible for the motor to run fine with a code 19 and with the automatic ecu? anythoughts

Did you wire a complete pre-OBD to OBD-0 conversion?

You really need to get a manual trans computer in there.

Do you have a complete 88-89 parts car? Forget any sensors?

I have access to 89 integras manual or auto, the auto ecu made no difference, i pulled the complete wiring from fuse box to fuse box i am not using any of the 1.5 motor wiring or computer, the motor isnt obdO, werent they released in 92 this is an 89? I know the d16a1 has electronic ignition advance where the 1.5 has the vacum advance. i havent replaced the distributor in on the 1.6 or the cam sensor. if the distributor is installed with 180 degress out of time would this cause it to run and shut down? or not run at all?

OBD-1 came out in '92. Everything 88-91 is OBD-0, 87 and older is pre-OBD. The change from vacuum advance distributors to electronic happened in the '88 OBD-0 update, so the 86-87 D16A1 has a vac advance. That's one of the reasons they are much easier to swap then the 88-89 mess.You shouldn't be able to install it 180* out. Take it off and you'll see it only indexes one way.

Are there any plugs you left unconnected?

ok, i read about the electronic vs the vacuum, do you think it would be possible to put a 86-87 distributor on an 89 motor and use my 86 si wiring and ecu? I have tried to unplug everything and start, nothing seems to make any differnce, i have went over everything, it either runs and shuts down every second or it doesnt start at all. i think my coil might be bad? or the crank sensor, wouldnt it show it in the codes? If you have a higher code for say 19, will it show lower codes that represent other problems, or do you have to fix the only code it shows to see another.

Kai

I'm not sure about the code display, it's always good habit to fix any existing codes anyway.

I don't know how the conversion would be done to bring an OBD-o engine down to a pre-OBD, either. Thinking about it, it should only be the distributor, but you'll have to look around for plug differences.

Do you have a multimeter to check the ignition components?

hello

thanks for your advice, i do have a multimeter and a chilton, time to test some circuts

compfreak2002

Put another distributor in, turn key start, runs smooth, apperently hondas have a famous problem with there distributors, strong motors though

Kai

Yeah, Honda thought it was a great idea to have internal coils for a while... looks like they are moving back to external coils these days.

Glad to hear you worked it out.
