the old PGM-FI thing - i have 87 honda prelude
My car has the good ol' PGM-FI dash light on problem. This seems to be
a common problem and I have seen a variety of explanations.
The light normally comes on when you turn the ignition key and
immediately turns off after I successfully start the car. However,
after I drive the car for 15 minutes, the light comes back on again and
doesn't turn off until I turn the car off. This is not normal. When
I start the car again, it will stay off again for a few minutes.
I have seen a number of explanations for this:
1) bad oxygen sensor (replace sensor)
2) problems with the solder connections on the main relay (replace
relay or re-solder all connections)
3) put fuel injector cleaner in the tank or get injectors cleaned
I understand the ECU might help me figure it out. But then I also
understand that the ECU is sometimes mistaken.
Any help would be much appreciated. My car stalled out today. I think
it was due to a problem with the ground wires but I'm still pretty
concerned.

1. go to tegger.com and get directions to the manual for your car.
2. locate ecu.
3. read error code.
the ecu's are usually pretty good for diagnostics. the only exception i
know for sure is the main relay in obd0 which often gives code 16,
failed injector circuit. but since the main relay does energize the
injectors, it's not all wrong, just misleading.

Re: the old PGM-FI thing - i have 87 honda prelude
I checked all over tegger and looked at every online manual they had.
the only one that was remotely close to describing where the ECU is
located was on the english website and the diagram was so vague I
couldn't tell what it depicted. the *other* diagram on that page was
the driver's seat so I assume it's somewhere in the cabin.
Anyone? please?

How about http://tinyurl.com/y6scej
If they talk about a "code reader" they mean a shorting jumper. (I bought
the manual with two "code readers" for $35 before I found out what it was!)

Re: the old PGM-FI thing - i have 87 honda prelude
Aha! so the ECU appears to be in the side panel behind the driver's
seat. now I just have to figure out how to get that off. Those
service manuals looked pretty helpful but didn't contain much info on
how to disassemble body panels.
