B20/gsr engine
My 94 EG started up perfectly before. I pulled the engine out and swapped out my cable for hydro tranny I then added a blox intake manifold put the motor back in the car and now she wont start. She cranks up but will not turn over. I checked battery, alternator, adn starter are all good. I just for spark, it seems kind of weak but its there. I checked for fuel also. Im going to check my compression and see what it is. but im looking for ideas because im lost as hell right now.

 

coil or coil ground?my del sol did this to me,would crank but not start and this was the cause

 

aiight i went and rechecked the fuel. Cause when i pulled the sparkplugs i didnt smell any fuel or see any. So i pulled the injectors and laid them on a towel and cranked the car. They didnt spray no fuel at all. But there is fuel in the fuel rail though, thats why i thought i had fuel. So what could be the cause of this. They worked before i pulled the motor out.

 

ecu, ecu fuse, wiring, main relay, fuel pump etc

 

I would check the fuel pump and fuel pump relay, seems to me like one of those two is out or going out since you're not getting any fuel.

 

ill check, the fuel pump primes though when i turn the key. I can hear it prime. Could it be bad injectors. is there any way to test them? I have stock injectors in

no, they arent getting signal to fire

check harness, ecu etc

 

hmmm, ill swap out ecu to see if it fires up. he harness is a stock 94 civic dx harness.
Is there any way to test out the signal to the injector clip with a volt/multimeter?

 

how do you test the injectors to see if they work or are receiving a signal?

 

you can get a injector signal tester i think its called a "noid" light

but if you have pressure at the rail and the injectors aren't firing you have a wiring or ecu issue. did you check all the fuses? check grounds too!

 

aiight i checked the grounds, swapped out ecu..still not shooting any fuel out the injectors. its to dark for me to check the fuses but ill check them tomorrow. is there any other suggestions fellas, i need help.

 

When I had my built b18b motor put back in the car, I removed the fuel pump fuse and cranked it a couple times. Then, I put the fuse back in then it still wouldn't start. So I checked for spark, etc..but didn't smell any fuel on the plugs. I removed the line from the fuel filter and didn't see any spilling out.

So I go back to my under dash fuel filter fuse removed it, and cleaned the contacts. Then I put it back in and made sure it was nice n snug. Put my ignition to the "ON" position then I can hear the fuel pump starting, and the smell of gas was present. Reconnected everything and she fired up!

Clean, replace, and check that fuel pump fuse.

 

the fuel pump works. i get fuel all the way to the fuel rail, but the injectors are not opening up. I swapped ECus and getting the same results. Im freakin lost

 

well i checked the dizzy and seen that one of the wires were cut. So i put it back together and it still doesnt start. im getting my homie to come over and swap dizzys just to see if it sprays fuel. anyother advice.

 

get new injectors? try that?

 

just because your getting fuel at the rail doesnt mean your fuel pump is good. Are you getting the right amount of pressure from the fuel rail? You should hear your injectors clicking as well. I had a car one time that got fuel at the rail, injectors were firing, and fuel pump was priming, but it still ended up being a bad fuel pump after all that!
