My cousin has a 94 honda accord ex and I replaced his thermostat for him one day and after i've finished we tried to start the car and it seemed to want to start but doesn't. It starts after a few or more turns. DOes anyone know what could be wrong??? Ignition problem??

 

Make sure to bleed the coolant system thoroughly and check the battery to start with.

Did you remove anything from the engine aside from the thermostat housing? If you removed the plug wires or anythign like that you may want to check to make sure that they were put back in there proper place.

 

no that was all and I did check. There was only one connector and the intake!

 

First please verify the majors then the semi majors. Spark, fuel pressure, compression, then actual injection occuring, mechanical timing intact, spark timing correct, battery power strong enough, ECU is actually alive by producing the 5VRef (maybe 12V) by testing power to say the MAP sensor (disconnect and probe the harness pins).

I would also test continuity through any connectors you disconnected or possibly broke in the area of work, unknowingly. A two wire temp sensor (ECT or TW) may tell the ECU that it is minus 40 degrees and it is flooding the engine while trying to start.

 

So... it does start, but only after a few cranks by the starter? And it previously started on first starter rotation, correct? Mine only starts first crank when the engine is warm, otherwise that sounds completely normal.

I don't know how cold its getting in your part of CA, but that can have an effect, otherwise it might be time for a tune up if it cranks "excessively" (IMHO like 5 or more cranks before start is excessive)
