hi i have a 1992 honda civic dx, recently i bought this and it was running , changed my thermostat needed a new one and my spark plugs looked burned so i got new ones and put them in, after doing that the car couldnt start at all, it cranks but didnt start , so i changed the dizzy cap rotor ignition coil, and even the spark plug wires, as well as the fuel pump, it sounds like it was abouta to start, but didnt, idk what it is thats keeping the car from not starting whether its the ecu since theres a engine light for 19 which is a automatic tranny antilock since it was switched from a auto to manual but it still turned on before that, please i need help with this!!

 

also checked my main relay and fuse box and everything was fine

 

The four little ground wires on the thermostat ground the whole ECU system. Make sure they are really grounded. If the bolts holding the thermostat cover to the housing or the housing to the engine are rusted, there could be poor contact.

Once it is running there is a way to modify ECU to make it work as a manual and not throw code 19.
