injectors are ALL getting POWER and GROUND...


PROBLEM(s)

** no spark... i took the distributor apart and checked coil and ignition moduel... both are in great condition...pulled spark plug out and grounded, turned key...no spark...even used inline ignition tester...nothing

*** no injector spray... all injectors are getting solid power (11.45) and ground... fuel getting to fuel rail... fuel pump primes and sends fuel...pressure unknown (?)

**** ecu: opened ecu, nothing fried... no bad or different smell... when key in car is turned, GREEN LIGHT in USB port comes ON (HONDATA s300) if there was a short in wires or ecu was toast HONDATA s300's"Automatically" throws a RED LIGHT showing there is a issue with the car's wiring (it did it when my main relay fried my wire harness underdash 8 months ago)

Q:
what else could prevent the car from giving spark

Q:
if injectors have solid power and ground AND fuel pump is working... what is preventing fuel spray.

more details from day 1:

***the day the car died the motor GRADUALLY lost powerover about a total of 10 miles, died about 2 times at stop lights, had to keep pushing gas and turning the key to get it moving again...when it would start after the dead stop, no matter how much i pushed on the gas the motor would stay at a very low idol as if i wasnt pushing the gas at all then would catch and start accepting fuel and i would be able to give the motor gas... while trying to get home over about 8 miles of freeway driving, i was unable to climb into high RPM's even @ FULL THROTTLE to keep with normal freeway speeds... i would have to downshift into 4th or 3rd to gain speed until the motor just died from fuel loss and ending up along the side of the road.***

** when i turn the key -NOW- the motor sounds like it would start if it could get some gas.... but it only turns over.... please remember, there is also still NO SPARK...
thx again guys

 

morning bump

 

afternoon the car wont run so i lost my job bump

 

Curious you mention you have both power and ground to the injectors. The ECU grounds each injector individually to open them. The ECU kills the fuel pump if it doesn't receive a signal from the distributor that the engine is running.

 

seems correct... i have checked each injector and each have power and ground... BUT for some strange reason the FUEL PUMP's hot wire (yellow/green) is not showing any voltage... even during prime

 

i do not know how to directly check the ignition mouduel and coil with a volt meter to know if they are good or bad... i only made a visual inspection... so i dont know for sure... i dont know where to place the pins of the volt meter to check corectly... and i also dont know what it should read.

 

I dont mean to be an idioit, but did you check all the fuses?

 

could be a bad ecm or loose pin fit somewhere.

try chnging out the ecm with a known good, stock one.

 

3 sets uf fuse clusters.... 1 large under dash... 1 near battery... 1 closer to passanger head light... ALL fuses in car check out to be A-OK... unless there is another fuse or set of fuses that i just dont know about...

Ive had fuses blown that looked to be ok. Prolly not your problem, but worth checking i guess.

 

i used a fuse checker with a light... all lit up
this is so frestrating...

 

Any CEL's? I think you may have a faulty sensor, or something's wrong with the dist.

 

NO cel... GOES ON...3 SECS.... TURNS OFF :CONFUSSED:

 

what kind of car is this and what year?

 

95 civic ex

*IF the distrubutor does not work... will that stop the injectors from spraying?

 

Yeah there's a CKP sensor in the distributor (crankshaft postion) and I'm 80% sure that if it fails the injectors will not pulse.

 

here is the update...
the KEYWAY that holds the pully in place some how got torn up... the crankshaft is now trash and has to be replaced... the reason i wasnt getting any spark is because the cams / timing belt were not spinning... i will most likely need a valve job as well...

now im looking for another b20 bottom end over at Hmotorsonline to get swapped in asap... i will not be rebuilding this bottomend because i will be selling the car... so pretty much i will be putting a bone stock B20 and hooking up the t3/t4 turbo to it... no pistons...no rods... just a new head gasket and a block guard... i will be making a new thread to find out what this set up should be safe for boost wise...im tired of all these issues, i will be selling the car soon after... this is a horrible day and it seems like **** just keeps getting worse with this car...
