ok so here is what happened, i changed the o ring on my injector cuz it was leaking gas. So no big thing right?? well i go to start it and nothing i just cranks, i see that the main relay is not clicking and fuel pump is not priming so i am confused and think ok wtf did i do so i look and one of the injector wire is pinched under the fuel rail. I fix the wire and try it again and nothing, so i think ok i blew something so i check all the fuses with my test light and everything is good under the hood so i move inside the car and check the under the dash ones and they r all good, soo i try a different main relay and nothing so i try one more and same. Now im starting to worrie and i try a diff ecu and nope still wont start i dont know wtf is wrong now, I think maybe its the pump so i drop the tank and check to see if im getting any power to the pump and im getting less than a volt with the "koef"(key on engine off) so i give the pump power from a batt and it works, so i know its not the pump. My bro checks if im getting spark and nothing so now i have no fuel or spark!! and have no idea what is going on. any help is be awesome thanks

Does the check engine light come on then go
off seconds later when you first turn on the key?

If not fuse # 14 is blown..


Also look through the oil filler hole while your bro is cranking it
and make sure the cam shaft is turning..
(ie: when the belt breaks,distributor doesn't turn= no fire or fuel..)

Is the battery fully charged?

 

cool ill check that, and i forgot to say that its a 90 civic hb with a d15b and im running a p28

so your car worked fine untill you changed your injector oring and pinched a wire? have you tried to swap the main relay out yet? may be possible you fried it when you pinched the injector wire??

 

He mentioned that in his post. He switched it out, and still nothing.

 

nope i tried 3 different ones

 

sigh im sad i cant drive my car

 

Sounds like ECU or fuse but you said that you checked them.

Does the check engine warning light come on for 2 seconds after ignition is first turned on? Oil pressure warning light on or off?

 

do i dare say ignition switch....

 

no the check engine light stays on thats why i know something is wrong oil light i dont remember i think it comes on then goes off


umm i haven't looked at that bout would that make me not get any power the the fuel pump or spark??

 

yes, have you tried jumping the terminals at the main relay? any codes?

 

i have the same problem w/ mine rite now im pulling my hair out i am getting the pump to prime but no pump wile im cranking. i have real good spark idk if it could be the resistor box or wut i did the same thing he did w/ the oring on the injector. (you had a big *** puddle of fuel rite? lol scraed the **** out of me. idk im thinking ignition switch. i wish i could figure out wtf happend i did all of the stuff main relay ecu, fuses, new gas.

i tryed spraying fuel in the intake and it worked so i think its something wrong w/ my pupm but it works so idk.

 

i tried that to when i sprayed car cleaner in the intake it didnt want to start cuz im not getting spark im going to check the ignition switch today and i have not tried jumping the terminals yet i will try that also thanks

take a test light and make sure your coild is good have someone sit in the car and have them turn the key on and off take a test light to the positive and negative side of the coil if nothing at all its a bad coil.

 

ill try that why my buddy comes over.

soo i was out checking the car and the only power im getting to the main relay is 12v's from pin 1 12v's from the batt, also i checked the ecu and im only getting power from one wire but not sure what it is im look for a layout to see what it is.

this is the pic of the pin thats getting power from the ecu

sorry for the bad pic cell phone camera

did you ever check the timing belt, and also if it's good then you need to check the coil

 

 

ok so fixed it... my buddy came over and we pulled the dash out to see if we could find a bad wire or something and everything look ok so then i got a hold of a wiring diagram for my car and the thing that was messing up my car and had me going nuts was................ the fuse box!!!!!!!!!!!!!!!! after a trip to the junk yard and about hour to but everything back together my baby is up and running!!!!!!!!!!!!!!!!! thanks everyone for the help
