Ok i just had my car running alittle while ago but now I cant get the car to fire up at all. The car is getting gas all the way to the injectors and has good pressure but for some reason the car wont start. I have good fuel pressure to the rail but, no fuel is coming through the injectors. Shuld fuel be spraying out the injectors if the injectors are taken out and just pluged into the rail? Coudl the injectors also not spray because of ECU?

 

Hondas rarely have problems with their fuel injectors. Have you taken the injectors to a shop to get them flow tested?

 

Disconnected wiring, blown fuse, stuff like that is more common than faulty injectors. But the result is the same - fuel gets to the rail but the injectors don't fire.

One wire from each injector should have a common color. Yellow/black maybe?? That wire should have battery voltage whenever the key is on. The ECU closes the ground side of the circuit to fire each injector. Check whether those circuits are OK.

 

Well i found that the injectors are not the problem. I have power to all 4 of them. I also swaped in my freinds new ecu and tried that but still same problem so that ecu isnt the problem either. Is there something else that could cause the injectors not to fire?

Also when i went to check my codes to see if a new code came up the SRS light just kept flashing constantly and the check engine light just stayed lit. Has ne one ever seen this before or know why it might be doing this.

 

do you have spark?

 

Yeah i have amazing spark. I jumps to a ground from 1/4inch away with a bright blue spark.

 

what kind of car?

 

The car is a 95 civic and the motor that is in is ls/vtec running on p72 ecu. After testing everything today I am pretty sure that the fuel pump is the problem because there has to be a certain amount of pressure to open up the injectors to fire fuel and also i just put in a new ecu from my freind and the fuel pump still didnt turn on so i bought the new one and built it and tomrrow im going to drop it in and seee what happens and hopefully this was the problem. If this isnt then I stumped becuase its not the ecu and i am getting fuel to the injectors and through the fuel rail and the pressure regulator is good atleast from testing it and the filter isnt clogged. I am getting reallly good spark and my battery is fullly charged adn all my fuses are good so the fuel pump is the only thing that i see it could be but i guess ill find out tomrrow.

Ill post what happens.

Maybe it's flaky wiring that doesn't always make good continuity?

The SRS light is separate. Airbags have their own control module.

 

true

 

put a noid light on one of your injector plugs to see if your really getting power to the injectors

 

theres a blank plug on the wire harness on the driver side of the firewall ....if soemone pulle dthe cap off that plug the injectors will not fire... you may have a jokester friend ******* around with you ( i do it all the time)

 

Well i got the car to start and run yesterday adn now today when i went to start it it wouldnt start and the main relay keeps clicking really fast adn sometiems not at all. Good the main realy be bad?

 

Sounds like it could be your relay.
What injectors are you running?

 

I fixed the problem. The ground on my thermostat was loose. But now I have a nother problem, I have no power to my wheels. The engine will rev up to 7 grand but the car feels extremely sluggish. The engine is just not givign ne power to the wheels. Im thinking that my clutch is slipping. Any suggestions?

 

maybe clutch is slipping, but how's the timing looking? and when's the last time you did a tune up?
