I just posted a question with you regarding my 93 Prelude not starting, I didn't mention that my check engine light comes on after the car is warmed up, would this have anything to do with why it's not starting?

3s, humm...... what is that, google shows ZERO for that.
can i know what object shows that? dash, ECU, trans shift.? what?
where are your eyes looking,?
is this the ECU flash code>? LED? at ECU?

"1985-91 Prelude models, there is only one LED display."
ECU code 3 is bad MAP (or bad vacuum to it)

Carb engine or EFI engine./ and which engine?> "options"

here is the FSM , look it up , gen 2 to 5

Just disconnect the negative battery cable for 5 Min's

No. 1 CYLINDER POSITION (CYL SENSOR)

Try another known good distributor. The signal comes from inside the distributor.

Check fuel pressure.

if its not taking gas when you fill up U should look at the evap emissions canister. could also be the intake air temperature or map / mass air flow sensor. Hope this helps out.

check your wiring for dirty connections or broken wires, you may have wires that are rubbed through or connectors that are not making full contact. you will need an ohm meter and check wires for continuity. a wiring diagram will be needed.

check for a blown ignition fuse in the fusebox. more info would help....Do the dash lights come on in the KEY-ON position?
Will it crank over? while its cranking is the engine light on?

Sounds like you accidently pulled the thin wire from you starter motor. Look at the connections at the end of the solenoid, mounted on starter motor.The thick red wire is Battery + next to that connection is a smaller male push- on terminal, locate loose wire (thin) in the same area and reconnect to male push-on terminal on solenoid or check if earth cable between body/battery to engine wasnt removed in the process.Also some vehicles you have to engage the clutch before starting, check for a switch located on clutch pedal where master cylinder connects to clutch pedal (Is clutch switch mounted and wiring connected?)

my 93 prelude was doing the exact same thing and for me it was my alternator was working properly.
go to a parts store and have them test it.

I am having the same problem; I cannot find a 93 Prelude sunroof. But the answer is no you can't use any other year of sunroof on ours. Just about everything else but the roof will fit. Hope this helped.
