Rb25det Starting Issues.

[rad100]

hey all..

i have a s2 rb25det into a r32 gtst..

mods:

gt3076r .82 ext gate

stock manifold with gate welded on

38mm turbosmart gate

740cc hiflowed stock injectors

z32

full 3inch exhaust no muflers

eboost

nisstune

splitfires

new plug gapped to .8

new oil

new coolant

oil filter and cooler relo kit

fmic

now when i try to start the car, whether it be cold or hot or after i just turned it off, it takes a good 30sec-1min to start.

it cranks and cranks but just doesnt wanna start..

it has done this with the car setup stock (when i first put the engine in)

i have the feeling its got nothing to do with the coilpacks, injectors, plugs as these are all new/working fine.. (have all been tested)

anywhere i can try to troubleshoot before taking it to a mechanic?

im happy to take it to a mechanic but i wanna try myself to learn and see if i can norrow things down before i take it..

cheers all..

Could be the non return valve in the fuel pump dumping the fuel in the line back to the tank. Ford falcon have these issues and its taking awhile to build fuel back up into the rail maybe you could always put the fuel line off to the rail to see if there is any fuel in the lines straight away.

ahhh yep... might have a look.. so the line that comes from the fuel filter into the rail?

or directly from the pump?

off the filter should be fine easyer to get to
