Me again. So I came out here to work on the z again, now the ****er won't start... I replaced some more hoses on the fuel rail the other day and now it won't start. I was reading more and someone said something about ecu flash codes. Do z's even have ecu flash codes? If so how do I check em?

unrelated question: the fusable links, what the **** is the deal with those. i understand how they work and the nacessity for them, but really? mine have to b on there just right or the car wont start... its rediculous, ive found fuse conversion kits for around $40-50, u guys found any cheeper ones?

so basicly, i should just replace all my fuel lines, and might as well replace my fuel pump and filter while im at it

i thought i had posted it, i did pinch the FPR vacume line, and there was no change on the fuel pressure gauge.

When I pulled them the other day hey were as U described blackish. The I'm working a 15 hr day today and tomarrow but ill post pics ASAP. I really appreciate all your help

i did all 6 when i first got the car, they were all 126-130 i believe

like compression test?

yey guage came today. dead it sits at 26psi, idle 30-31psi, and 3-4k 30psi. ill post a video in a bit

so i think this guage is bunk.. nuthing happend when i pinched the FPR hose, and it didnt move when it was at 3000 rpm. so RIGHT NOW im ordering the fp guage and T fitting...

wierd. so my buddy had a fuel pressure guage. just popped that bitch on. it idles a just a little shy of 30psi. what im wondering now is why does it stay at 30psi when i pinch the return line? pretty sure it should shoot the psi up right?

somethin like this for the T fitting? http://www.summitracing.com/parts/MRG-2975/

ya i realized i wrote maf sensor instead of AFM. on with the tinkering i go. thanks

wooow. the shitty part about living on an island... Ace, Napa, and Carquest all dont have anything even close to what i was looking for. what a bunch of assholes... my machanic buddy i ran into said its prob the MAF sensor but im ganna continue with trouble shooting before i go and spend $200 on something i potentionally dont need...

true that. ima check that out tomarrow

Ya I was reading that in some of ur other related threads fastwoman. CozyeStill waiting to get paid to order the fuel pressure gage.

Ya once I get my buddy out this weekend to check it out, if we figure it out ill letchya guys know what the problem was. In. The meantime, any more troubleshooting ideas why it would still be running so lean?

horay for the yogurt test. fixed an air leak (injector to intake). so pay day ill order a fuel pressure gauge. im havin a buddy's step dad who was a z machanic come over this weekend. hopefully that will sort out my $^!#. i really appriciate the help. this is the most helpful forum ive ever been on

sometimes when i first start the car it will seem fine and accelerate great for a few seconds then the problem will kick in again.

the original problem wasn't so much a "rev limit" it was just more of a not wanting to give any more power because it was running too rich.

about the TPS? ya its not the TPS. like cozye said it ran decently with out it even plugged in. havnt had much oprotunity to work on it much more in the past few days.

thx. im waitn on the fuel pressure gage to help narrow my search down too. ill start replaicin vacume and fuel lines for now. in the mean time, i have a california 280. can i just pull all that california $^!# off? will the car run fine? i live on an island where we have no smog controll so im not to worried about smog

i appriciate it guys. any trouble shooting ideas??

hey guys, baught this 280 from a lady who baught it off the lot in 77. one owner, she "drove it till it stopped running." well its running now. but im kinda goin nuts on what the deal is now put it in gear and accelerate and it doesnt run right. backfires (through the intake) and doesnt want to rev past 3000. thought it was the coolant temperature sensor. orderd a new one that wasnt it... ive lurked around threads to try and find the problem. no luck yet. figured ide ask the pros and see what kind of help i could get in resolving my running problems. thanks Brento
