Well I've had my rb25 for a while and i finally saved up enough money to do some stuff to the car. So I bought a t3/t4, a topmount manifold, and a greddy intake manifold (easier intercoolerpiping).

I finally got everythign hooked up yesterday and for some reason the car wont start. it starts every once and i while but it idles for only a few seconds then stalls. ive checked spark, im pretty sure im getting fuel cause one of my fuel lines shot off the first time i tried to start it (it wasnt tightned down enough). and ive checked the maf.

i just dont know where else to look.

heres some pics:

Before i did all this stuff:

As it sits:







if you need me to take another picture of something let me know.

any help is muchas gacias

(edit) sorry for the pics being so big i fixed em

looks like your fuel lines are reversed to me. the fuel system should flow like this.....

fuel pump-> feed line-> fuel filter-> fuel pressure gauge-> fuel rail-> fuel pressure regulator-> return line back to tank
