just finished swap and wont start...

[TimTheTool]

ok so i just finished my rb25det swap sunday night came out pretty clean but it will not start. i have my walbro fuel pump it turns on with the key and has good pressure. i have the nismo fpr. i checked my plugs and im geting good spark. i have not ajusted my fpr yet. will the motor still start with the fpr not ajusted?im geting power to my injectors. motor turns over but just wont fire up and run.and i have 3 small vac lines that are not hooked up 1 next to the brake booster line and the 2 that are conected to the hard line that runs between my valve covers and my intake pipe should i judt block thies off? . would thies 3 lines not let it start? to me it sounds like the motor is not geting fuel. dose the fpr run or open off of vacum? thanks

There is a vacuum line on the top that you need to hook up.

Also, beware that people frequently run the fuel lines backwards. It's a very common mistake.

Check your fuel lines. They might be reversed. From the FPR back to the tank, not to the fuel filter.

I agree with these guys..

You need spark air fuel timing compression.

You more than likely have compression and timing if you havent messed with it. and you said you have the rest including injector pulse.

Feed > filter > fuel rail supplyReturn > back of fuel pressure regulator

Spray some ether or carb cleaner in the tb -- just a spritz or two and see if it fires. Then you will know its fuel related
