i pull killer jailbiat on the weekends.

[midnightsliding]

and i need my car running agine.

so i was coming back home from work, and my car started bucking like it had a boost leak/ and or it was running out of gas or something along those lines. so pulled over and it had really low/shiiiitty idle. then i cut it off and once i cut it off it has not cranked back up since. it turns over and catches like its about to start but then continues to just turn over. im pretty sure i have fuel/ its registering 40 psi when the key is forward, and the fuel pump is on. have not checked spark. or anything else i have to get it back to my shop some how b4 i can really work on it i just wanted to see if their was something to look for.

set up isRB25det into a Q45. SAFCII.Q45 mafs, T3t4 turbo, stock exhaust manifold, FMIC, stock injectors. ill get a video up tonight if i remember to get some batteries for my camera. any help will be ****ing rad. thanks a head.

sounds exactly like what happens when intercooler hoses pop off, other than that check your maf and whatnot.

[Carl H]

if not that then behold the power of a blown motor due to safc pwnage.

[Darius]

prolly an unmetered air leak. symptoms are exactly like that.

[DJButton]

Prolly trying let loose it's RB goodness and ability to not be running 80% of the time or higher.

[midnightsliding]

if not that then behold the power of a blown motor due to safc pwnage.

could that really happen after 6 months of running fine?

ill check my MAFS tomorrow. i think it was too close to the compressor housing anyways so maybe that might have something to do with it.

[midnightsliding]

went and unplugged MAFS, to see if that changed anything. nope still dose the same thing. i guess when i get time ill have to look into it more. but keep the ideas coming that way it helps me trouble shoot faster.

[matafied]

Hmmm dose sound just like a boost leak but it that were the case it should still fire up, or at least get something. every time ive had a hose blow off ive been able to fire it up at idle, granted it sounded like poop. well if you need a c.a.s. for troubleshooting or ecu let me know i have extras

[midnightsliding]

yeah thats why i kinda ruled out boost leak. just b/c i would still be able to get it to idle. once i get some time im going to check my wiring and what not ill be in touch though..

[midnightsliding]

alright so today i took 30 mins to work on my car a lil bit!

so heres what i got. i pulled C.A.S. and rotated, and i could hear the injectors firing. and i also pull the coil packs and have spark on each cylinder. so this tells me that my CAS is still good? and the my coil packs are alright also? right. so if i have fuel and spark what else do i need in this equation? i have like 42 psi at the rail b4 i try and crank it, but im not sure what i have after i turn it over maybe im loosing fuel pressure or something? input would be greatly welcome..

[midnightsliding]

think it might be a leaky fuel line. i have this one clamp that vibrates loose so im going to replace that tomorrow and try it agine.

[midnightsliding]

bump still the same but now with out a leak. wtf..

[midnightsliding]

alright heres the new up date for compression check. Cylinder PSI1. 1602. 1603. 1604. 1555. 1606. 155

had jumper cables on the car, so i had 13V before cranking, and 10V while turning over. with WOT. next suggestions?

[rustbucket]

How did your pulgs look?

i.e. black or white or brown etc.

[midnightsliding]

a lil black. but not as bad as i would of thought they would of been

[matafied]

Time for the ecu

[sleepin240]

before you go ecu crazy i would try another maf, mine wont even run without one at all. It just acts like it wants to start and then nothing.

[matafied]

yea defanatly, but you can check that with the afc cant you??

[midnightsliding]

that or i can just plug my other Q maf up. ill give it a shoot today. thanks.

[yourmomsrps13]

same exact symptoms happened to me and i just now pulled the #6 piston to find broken rings, now i cant find ANY OEM replacement rings in the USA. not to thread jack but if anyone has a lead on OEM series 2 rb25det rings...let me [email protected] thanks

[Carl H]

ring replacements are out there, just measure.
