91 civic ex with ls. I had ls in the car for almost a year with no problems.
installed turbo with xerocron basemap, walbro 255, 450 dsm injectors. Now the car wont start. Check spark ,getting some good spark, check fuel ,fuel pumps primeing but its not coming out of injectors. Anyone have any ideas.

 

What are you using to tune the car?
What is your KOEO fuel pressure?

 

well its like 28 degrees here so i didnt get around to check fuel pressure. but i pulled the injectors out and turned key on theres nothing. IM running a xerocron basemap for now. To get it to the tune shop. Could it be the main relay if the pumps primeing

 

Injectors might have changed impedance on you, from your old to your new.

If the fuel pump is priming when you hit the key, it shouldn't be your relay.

You pulled the injectors out of the fuel rail, or out of the intake manifold?

The best course of action would be to check and make sure you are getting fuel to the rail. Loosen the nut on the fuel filter and see if anything comes out. Have a rag ready to catch fuel so it doesn't get on everything, and loosen it slowly.

 

Checked it at the intake manifold. i can try to check it when i get off of work at the filter.

 

If i check it and theres no fuel coming out of the filter what could it be
If i check it and there is fuel coming out of the filter what could it be

Just tring to get some info before I get home so i can start going threw the process of finding the problem. So i dont keep running in and out of the house tring to get answers.

 

if its not coming out look for bent lines and such it could also be as simple as a bad/drity filter.

 

thanks , ill look for that. quick question. does the walbro need to be primed manualy. like a swimming pool pump. Just a thought. Tring to eliminate the dumb stuff

 

nope walbro's prime them self just fine.

 

28 degree freezing weather... atmospheric pressure I am guessing is greatly affected at these tempuratures...

 

whut? lol

DSM injectors are low impedance injectors (2-3 ohms) .Are you running a resistor box? Best place to check for fuel delivery is at the combustion chamber. I dont recommend checking it at the fuel filter because that wont tell you if the injectors are opening. Crank the motor over several times and pull your spark plug and smell for gas.

When you bought the basemap, did you specify what size injectors?

 

update guys. wow im dumb. I put 10$ thinking that would be enough to get it started. Well i was wrong at 3.81 a gallon 10 bucks dont do a whole lot. Especially want the car was facing down hill. It runs pretty good but that only thing i got on it alittle and it broke up at 6 grand like hitting a rev limiter
