I just finished my MPFI, I checked my wiring at least 10 times and its fine but when I crank it the engine turns but doesnt fire. My questions is where does the hose from the fuel filter go with that donut shape, in the DX manifold it had a screw with a hole that the fuel passed but my Si doesnt. Any advice will be appreciated. THanks guys

 

I did my wiring according to this site http://www.fourthgenhatch.com/mpfi.html does anyone know if the info is correct?

 

Come on guys, need a little help please I need my car by monday night. I also need the vaccum line for the manifold. If your in the LA area I will pay you some cash to get my car running Email me if interested

 

The fuel line goes from the fuel filter to the fuel rail on the intake manifold. The fuel rail has a fitting on the end that is threaded. Just slip the fuel hose "donut" over the end of that threaded part and secure it with a nut.

 

I did exactly that the DX fuel line nut in the manifold as a hole in the thread but the Si manifold does not, does this matter. I am not getting no fuel what so ever

 

Make sure you use the SI fuel line from the filter to the rail. They are different. the loop at the end is bigger on one side to let the fuel flow through a washer into the endcap ( from the SI fuel rail not the Std) and then into the rail. if you use the Std line or cap, no fuel.

 

What Cvic90 said, you cant use the DX fuel line. You need an Si one.

 

Thanks I appreciate it guys, I knew that the fuel line from the filter had to be different. Now Im confused on the wiring, could anyone tell me the color of the wires in the EACV plug and IAT plug I have them confused and have no idea which one is which, praying that by tomorrow afternoon my car will be running been borrowing my dads car for four days now and he is about to kick my ***

I'm pretty sure mine was like that with my sir swap, I really never heard anyone else having this problem. Anyways I drilled a hole into my fuel rail and everything worked great.

 

Hey guys could you give me the colors of the DX wires going into the Si manifolds EACV plug and IAT plug. THanks I have them confused and do not know which one is which.
