    havent posted in a long while. my GSX has been having some issues for the past year and cant seem to figure it out. it basically started no starting once hot and would only crank then eventually would start, been over everything trying to figure that out, found some messed up ground wires and moved the battery to the back of the car and fixed the ground cable mountings, So i got out today and start it after finishing up the catch install which was only running the braided nylon line. let it run for about 25-30 mins, noticed it started to slowly idle surge and cel was on didnt have my lap top shut it off ran and graabbed my lap top and code was gone, tried to restart it and it will not restart now, used a spare plug and confirmed it has spark, pulled a plug from the engine its completely dry, no fuel, fuel press on the fpr is over 40 psi, checked power on pin 3 at the resistor pack has battery voltage, unplugged a injector and have battery voltage on each side of injector, changed the resistor pack with a spare one i have no change, can hear the walbro turning on and running while cranking. tried swapping out the cas with no change, any help would be appreciated.

    No e 85 in my area she is on 93 octane. Going to see if it starts this morning and see if I can get anything to come up not sure if the drivers in ecm have gone bad or harness is no good

    check for fuel at rail, and are the injectors pulsing what injectors is the car stock.

    Listen, I know this will sound stupid and I'm not just posting for the sake of it, but do you have enough fuel in the tank? Legitimate question. I've had it a few times where not enough fuel caused no-starts or very low surgy idle. I should point out that even if the fuel gauge needle is showing above the "E" mark, fuel can still be so low and not spread evenly in the AWD tank that the pump can't pick up and sustain enough fuel to pressurize the lines/rail.

    Are your injectors set up In link correctly, did you adjust anything I just went through this, and I need to add more fuel , she started up after that. I checked for spark, compression, I knew it was fuel related since my injectors were just cleaned, well that was it.

    It had just been running it started to surge slowly then , shut it off to grab the laptop and wouldn't restart checked that everything seem to still be set up. I'll add some fuel tomorrow it's not terribly low about 1/4 tank. Have had it running with the tank being lower on fuel but I'll check it, also will pull the fuel.line to see if the filter got clogged but again the fpr is reading 40-42psi

    How old is the fuel pump sock and filter up front?

    Use the turn pump on feature in link to confirm if the pump is building pressure. Could be a pump going out even if you hear it turn on

    Ecu??

    Do you have a spare PTU? I think a bad MPI relay won't give you fuel if I'm correct. But you said it was running before...just some ideas that come to my head.

    Capture a log trying to start it. Maybe someone experienced can spot something wrong

    I have along of it happening, was able to get ahold of some noid lights no injector pulse, I do have a spare used ptu. Already swapped that out no changed measured voltage at the y/g and y/b wires have battery voltage there, also tried swapping cas unknown condition of the 91 + cas, No change trying to locate another 90 cas
    Checked continuity to ground on the grounds for ecm those are good, getting power into the ecm in the right spots, also tried swapping out coolant temp sensor with know nbn good one no change. injecting duty cycle on ecmlink is staying low .5%, timing is also staying dead locked at 5 degrees. It set 41 code twice

    Having a tough time with this gone over every possibly issue, swapped ecms with ecmlink same issue, removed the wiring harness and open ed d up harness and checked for chaffedor bad wires no e found ohm tested all wiring for injectors is good, swapped out injector resistor packs, also swapped out the mpi relay, three different known good cam sensors , even tried a different power transistor, , checked mechanical timing is dead on. not sure what much more it can be pin fit on all connectors is good installed ne injector connectors ( soldered and heat shrieked) have power to injectors, at times has injector pulse some times only seems to have signal on two injectors

    Have you tested the resistor pack?

    Yes but the readi gs I'm getting just seem to be continuity readi g I'm not getting the 5 ohms of resistance readings from pin 3 to the others, so far I've tried 3 different packs all used resistor packs supposively out of running vehicle or that were running. Have another pack coming in a day or so, going to try it again, can't find the resistor pack new anywhere havent tried mitsubishi yet tho.

    This is the correct way to check the resistor packs and the ohm readings you should see:

    http://www.dsmtuners.com/threads/injector-resistor-pack-test.382964/#post-152340878

    Should that be a problem and you need a new one, they can be found here:

    replaced the cas sensor after having ecm link take alook at the ecu and determined the ecu was fine and ran their test vehicle, ordered a new case now have better injector pulse but ecm link reviewed a log and is saying the cause of my issue is the ecu isnt seeing a cranking siganl. not sure what more it could be, cas sensor is from rock auto. looks like it has a mits number and emblems on it. havent posted logs in a while so forgot how to post it but i do have logs of the issue, crank signal (rpm on link is only showing spuratic rpms range, until 200 rpm then falls flat.

    Found the issue when the harness was out and I was fixing wires that were hacked by old owner, accidentally mixed up the cam and crank signal wires to the ecu by mistake eepinned connector it's good now , cas sensor fixed the no injector pulse also
