Question about 2004 Honda Civic
Car stalls at lights and is hard to start after. No codes
No DTCs. (even cranked for 5second, you must crank to see them. pop up, P0340 355s etc.)
all fuses good? ever do a 60k mile tune up, ever? it repeats and is critfcal.
so you crank it.
you check spark at all cylinders, 4 to 6? (no engine stated)
got spark? you check timing with a "timing light" and its
WAY OFF, opps you skipped the new cam belt, service and if you
keep cranking it , you bend the head valves. ($$$$$$$)
ok, sparks good, and timed good.
its bad fueling?
you examine spark tips
all are wet, all are dry, or 1 or 2 are wet and others dry.
(this is called evidence)
this all assumes engine compression is at spec. 150PSI or more.
we then trouble shoot , these facts.
lean? , we check for low fuel pressure. and MAP /MAF sensor and ECT
rich? same thing, but this too high fuel pressure.
how cold is it outside. -50F or +80F in florida keys)
we check that the 2 sensors match that before first start. parked overnight.
the my both be near ambient, ECT and IAT.
scan tools allow you to see all the sensors. to see if they are fibbing.
a $9 tool.

Remove your passenger side kick panel, remove the TCU, take cover off of it and see if #36 or #39 is burnt if so replace it.

SOURCE: stalling at a stoplight
sounds like your not getting enough gas try first determining iif your getting enough fuel from the gas tank to the engine and if not you might half to replace the pump because the fuel filter is part of the pump by you might be able to find just the filter somewhere, but if thats not the case then check your injectors there could be one the is misfiring or clogged so try also during a good fuel system clean on it

they are known for bad distributors.there is a module inside the distributor called an ICM,and if it fails,the car will run like that.Also check that the ECT sensor for the computer is operating at less than 1 volt dc.A bad coolant temp sensor will cause a hard start condition.
