The eCU never injects if it ever thinks there is bad spark or spark precursors (ckp/cmp sensors)
and hark tells you, with the scan tool just that. ever used a scan tool>
real>? in your case this is true, (3 second dropP
here are the correct steps.
1: fuses good.
2: key on, immoblizer lamp out. (got that? option?)
3: CEL , Charge and brake warning lamps all on, if CEL is out the ECU is dead. CEL means Check engine light ( aka: MIL or SES)

4: plug in scan tool to 16pin port (USA cars, i dont do non usa cars)
and the obd2 scan tool comunicates and works, if not , pin 16 fuse is blown to 16pin DLC connnector. if Scan tool works. and you see
the TPS move with right foot action then crank car for 5seconds.
the ECU will show RPM work. 250?
then may throw 2 DTC'S or more.
P0340./355 etc, telling you why it cut the main relay, and all injections.

The ECU is amazing, this way,
the ECU can also see primary spark bad, and show that
i can not see , secondary spark bad. (until running and that is called misfire)

get the scan tool they rent cheap or free.
in USA.
if not in the USA all comments here are useless.
other countries use OBD1 or other protocoals.

known exactly what engine your car counts big time.
as EFI varies greatly by this.
D16y5,7,8? B16A2? both are 1.6L
15 D engines
lots of B16s seen here

first know what engine,
then get the FSM and learn what makes it happy.

each engine can have unique spark systems. (3 possible world wide)
wasted spark, coil. 2 dual coil packs.?
COPS, 4 cops on top plugs?
each has unique troubleshooting techniques.

SOURCE: 91 honda civic dx. Starts, runs for a few seconds then stalls

Try pounding on the gas tank with a rubber mallet or similar tool. (careful not to dent the tank) Try starting it. If it runs, replace the fuel pump (it's nfg). I've diagnosed numerous fuel pumps this way. Remember the pump needs to be replaced, if you drive it, you don't know when it'll fail for good. Hope this helps. Please post the results.

SOURCE: '95 Honda Civic EX will not start after cleaning fuel injectors

I would talk to who cleaned the injectors, I don't know if it something they did or not. It could be a stuck open injector. The exhaust would have a raw fuel odor if it was. What it sounds like is a blown headgasket, which can just happen. The exhaust would have a sweet smell to it. Usually starts as a small leak (between cyl. 2 & 3), the engine burns the coolant while driving which you don't see. Then the coolant level gradually drops to a point where the car overheats, which warps the head, causing a large leak. Now you see the coolant burning (white smoke).
Good luck Honda Al

SOURCE: 1991 Honda Civic 1500 idles irregularly, with check engine light.

I think I would suspect the fuel injectors, especially since that is the code you are getting. Fuel injectors clog up, get dirty, stop working the way they should. They can be cleaned (you can remove them and send them to a company that cleans them and makes them like new, or, they can be cleaned in the car by some garages, or, you can get a can of Sea Foam spray and spray it into your throttle housing several times to try to do some cleaning that way, or, you can dump a can of Sea Foam (non-spray) into your gas tank and run it with the fuel through your injectors). You should probably check when you first start the car to see if you are getting any leakage from one or another injector (one or another may look moist or wet if the seals are leaking). You can also do the long screwdriver test (hold the bit of the screwdriver against each injector in turn and listen with your ear against the other end to see if each is clicking regularly). I would try the Sea Foam first.
I hope this is helpful in getting you started on a fix.

I have a civic 04 ex automatic the key don't come don't have spark and the injector not pulsing does the inmovilizer have something to do with this problem ?

just went through similar issue with a 99 accord spark would be out because of the crank sensor but wouldn't kill injector pulse there is what is called a main relay honda used it controls both the injectors and fuel pump my car wasn't getting fuel pump power if you pull relay down should be next to brake pedal under dash and 7 wires and pull internals out and check circuit board for burnt solder or cracked solder when i wouldn't hear fuel pump i would take and apply light pressure to circuit board then fuel pump would kick in the injector side should be 6 volts and fuel pump should be 12 volts i would change crank sensor and get spark to return and then trouble shoot injectors also my car had after market remote start and keyless entry and was causing the key not to be recognized i removed alarm and got the coded key to read then had to trouble shoot the other problems after rectifying others first

I have a 97 civic I am not getting fuel or spark

Most likely Camshaft sensor, located in distributor, is just the right age for that problem.

I have a 1992 Honda civic lx with a 1.5 four cylinder, and Ive replaced the ignition switch the fuel pump relay and the fueled pump itself however, the fuel pump still doesn't prime when I turn the key...

no start , crank perfectly
so , got spark?
the ECU has programming (ROM) and in fact kills all fueling with no spark , (even if it thinks there is no spark, even if spark is ok)
all ECU use a way to read back spark quality, (ALL){LAWS}
how honda does it in code, i don't know , see C R O M E forum)
turn the key over means nothing to me.?? sorry, it doent/
try saying what postion? cranking? or just keyon.
now some more EFI rules.
The EFI (some) do not activate the pump relay until cranking.
some do just key on for 3 seconds, read the FSM, its free.
need a link to the free manual? read the ECU logic on that.?
and prime has a special meaning, it means purge air,
its not for fuel. some system send a fast prime pulse. to clear air from the pressure lines, this plus does not inject.
that is how EFI works,

the flow
1: key on, ECU sends prime pulse, (air purge)
2: some ecu, run pump for 3 seconds, and pressure hits 35psi? RTM.
3: all ecu activate pump cranking and running.
4: now check pressure. !" 36 psi FSM stated spec"
5: now crank, if the ECU sees no spark errors, it injects
6: if the ECU sees WOT. it stops injection to clear a flood, cranking.
those rules cover most ECU made.

honda this year has a special feature called,
Fuel Cut-Off Control'
if this messes up, it i can cut fuel
does this help?

1999 silverado 2500 6.0 motor wont start

If the passkey system were not working the engine should not crank and the fuel injectors would be dead. The security light would also stay on.
The fuel pump relay gets battery voltage and also voltage from the key switch. The computer grounds the relay to power the pump.
The crank sensor does not come into play until the engine is cranking and it supplies a signal for the ignition and injector pulse.
Are you not getting power from the key switch to the relay, or from the battery side to the relay ?

98 crv won't start

Check compression and timing belt. If belt is ok and you have compression, check to see if you have a pulse at the injectors. You use a device called a NOID light (basically a light bulb that plugs into the injector plug. Unplug the injectors one by one and plug the light in then crank the engine. Light should blink on and off if the system is working properly. If not check for a bad crank sensor, blown injector fuse and wiring harness. Hope this helps.

Car won't start I think its the fuel pump. Cause there's no gas going to the injectors. But to save money i was wondering if there's a fuel relay,sensor,fuse or something?

well you wont save money if you guess either but do this. Is it equipt with a tach meter (RPM range)? if it does we will use it to trouble shoot the car. Okay when you crank it do you see the needle moving just tiny tiny bit,if you then we know there is coil pulse are pick up by the tach. Okay now the fuel section have some one cycle the key but dont start. have the gas cap open, use you ear so you hear the pump,it will be hard to hear , can you hear it, now lets check the ignition switch why check Honda uses a ground signal to turn on the fuel pump when your ignition switch fails even though it cranks you wont get a fuel signal. and no pump the only way to know for certainty is a test light, there are relays that why you cycle the switch and there is a pump fuse and that in the engine comportament and it is marked as fuel pump fuse.

Have a 1990 honda civic that sometime fails to start the engine, already changed the fuel pump, but the problem persist. for your info, when this happens I found out that there is no gasoline in the TBI...

if the fuel pump is working, then it could be a plugged fuel filter not letting fuel to engine. if crank shaft sensor has failed or is failing. there will not be any spark or pulse to injectors.
