I got a 91 civic that starts perfect,runs tntil warm then cuts off with check engine light. I try to restart it (sometimes fires right up, got to wait maybe 5 mins). Had it put in shop, they changed filters, fuel pump, blasted fuel lines, changed main relay, tested fuel injectors, blasted gas tank tested yellow and blk, changed rotor and distributor cap, tested distributor and checked ecu valve. It drove fine for a month then same problem. Old school mechanics say vapor lock, but that's not supposed to be possible in rear fuel pump/fuel injected models is it? Need help, love my Honda but I'm about to light a rag in the gas tank!

. Check for codes.

. Replace the Ignition Control Module (ICM) and coil inside the distributor. Be sure to apply silicone heat transfer grease to the back of the new ICM. If the problem persists, install the new ICM and coil inside a new genuine Honda distributor housing--all others are suspect. Internal sensors (TDC, CKP, and CYL) get damaged over time and are not serviceable.

Will a 95 integra distributor fit a 91 civic? If not can the icm or coil fit?

I'm not sure.
