2001 Honda Prelude, No Spark when cold.
Car has no spark when its cold outside and therefore won't start. New dizzy, coil, ICM, CPS, CTS, spark plugs, fuel filter, timing belt, water pump. Car began the problem before any of this was started. Problem began after I did a compression test and did not pull the fuses. IF you try long enough the car will start, run like crap for 2-5 minutes then run fine. When its warm out, the car starts perfect.

Distributor? Hows the firing order?
firing order is correct, new distributor. Problem only happens when it is cold outside.

Could be an o2 sensor.

Is it throwing any CELs?
twenty-two
Only CEL's that come up is from misfire because if you try hard enough you can get it to start, runs like crap, then fine. Other than that? nope. has a new upstream 02 sensor too

Have you checked all the fuses and relays?
twenty-two
yup everything seems good, checking wiring at and near ECU and checking ecu. What has me stumped is the temperature thing. Once it gets close to 70, thing will start and run great

well...we put a space heater in the passenger side floor and ran it for 5 mins, the car started right up....smh

Yeah that's usually caused by o2, IAT, CT sensors.. But no cel
twenty-two
leaning toward the ECU now...gonna try warming just that up in the morning....the first 02 sensor, the ct sensor have both been replaced

Facing what? the ecu? Maybe some brittle solder on the board in the ecu?
Yup, facing the dash. We kept thinking the Temp problem was under the hood, but now it seems that it is inside the car...

if it's stock, see if someone will let you borrow an ecu to try it out. I have 2 that would at least crank it, but I wouldn't drive on it. (F-series ecu's)
thats the plan tomorrow. We know a honda-tech that thinks he has one laying around to try. Hopefully that fixes it. Worst part about this thing is we have to let the car get cold before we can try something else. Lol

Ecu was the issue
