fuel issue

[mattysr20]

ok this is my first post so lets see how this goes. First off ive searched all over but can find exactly what i need. So here is my issue..

Ok so about a week ago i drove my 91 240 with sr20det swap the car was running amazing as it always has i wasnt having any issues at all. The sr is all stock with...
apexi intake
fmic
hks boost cont
walbro fuel pump
hks hi flow turbo back exuast with megan down pipe.
So your normal mods.. anyways i drove from ohio to tennessee wich is about a 7 hour drive i stopped 2 times with no issues. Well when i got to tn i came too a stop sign and the car stalled out i didnt really pay much attention too is just figured it was the long drive. After starting the car back up i drove about another 2 or 3 miles to my moms house when i pulled up into the driveway i got it sideways a little lol then the car stalled again. I just went inside and left it i figured it needed too cool down soo about 2 hours later i get in the car it starts right up i drive about 1000 yards down the road as i turned into another road i got on it a little but not wide open as i shifted into second the car backfired then died well it was still running as i was gearing down but when i hit the gas nothing happened (motor was still running) no weird noises or anything no fluids leaking none of that.

Ok so after all that me and my buddy who is a ase mechanic for over 25 years looked the car over we could not get it to start back up. It crancked but wouldnt start we also descovered the fuel pump would not prime when the key was turned ...

Things i did...

new walbro
new fuel pump relay
checked fueses
checked power too all fuel sorces
changed fuel filter

I also had a buddy that knows alot about sr's and is also a mechanic for subaru look at it we tried everything we could with no change...

Things i think it could be are...

fpr
vapor lock
the harness too the fuel pump
another relay?
ecu?

So now im just looking for answers from more people has anyone had this issue before? any ideas on what it could be?

ANY and all help would be very needed as i need to get the car back too ohio thanks alot and if you need more info just ask THANK!!!

Lets start with the fuel pump not priming.... Have you bypassed the egi relay or tried using starting fluid to sew if itll run? Any codes? One of your mechanic buddies should have checked that first. Also any spark?

Might be better off posting this in the SR forum.

Naah. There isn't enough traffic in the sr forum. He'll be better off here.
