reliable cars come from routine maintenance. (aside from recalls and whatnot) if you're lazy and skip an oil change, you've granted your car the chance to die. keep up on a good maintenance schedule, and you're golden, even if the motor is modified. i mean, hell, you can have a fully built and...

heh, i cant even reach boost, nor would i want to with dropping pressure like i have :( i do still have my old stuff, but i'm not about to put the stock FPR back on, and hack up my nicely soldered new injector clips to put my 440's back in. well, i'll report back after i return from the...

you adjust it by loosening the two set screws that hold it in place, and move the throttle plate to different positions following the recommended calibrations in the TSRM. once you have it within spec (resistance compared to throttle plate opening) then you tighten those screws down nice and...

anyone have a comment on the fuel pump relay? there's two terminals that are supposed to have continuity between each other that dont... could that cause my problem? i'm going to the junkyard tomorrow to pull one out of a junked supra, (the ONLY one i've ever seen in a junkyard...) i'll see...

what exactly did they do to fix the ECU? that's kindof weird, i've never heard of shops doing work on the ECU before... hissing at idle is definately a vacuum leak. there shouldnt be any hissing at all. it wouldnt blow air out, it would suck it in, which lets in unmetered air and plays all...

check your ISC (idles speed control): http://www.cygnusx1.net/supra/library/TSRM/fi/FI_106.html check your TPS (throttle position sensor): http://www.cygnusx1.net/supra/library/TSRM/fi/FI_101.html -shaeff

dont hardwire it. either get new connectors and solder/heat shrink them on. (then use brush on electric tape over the heat shrink to prevent all corrosion) or get good marine grade waterproof connectors to solder in. hardwiring just causes problems when you try to remove your engine harness...

i tested the ground back there before i put the pum back in, and there was 0 resistance. unless something got messed up when i put the tank back up, it should be fine. i'll doublecheck it tomorrow. i'm at work now :( here's a question: i tested my fuel pump relay. the manual says that...

see link in my sig. ;) -shaeff

ok, i'm getting 12v back to the fuel pump. i tried re-connecting the resistor, and the problem only multiplied, so i changed it back to the 12v mod again... pressure still drops with RPM. -shaeff

DAMMIT! did you listen to your injectors? maybe one is stuck open? -shaeff

i put my old T-belt on just for shits and giggles. it took like 20 minutes. base timing is re-set and perfect, as is ignition timing. my AFPR is an aeromotive. why does my fuel pressure drop when i rev the motor? if i rev it and hold it there, the fuel pressure constantly drops. it builds...

you sir, are correct. -shaeff

alrighty, i'll give it a shot when i get my timing belt back in. my fuel pump is a brand new walbro 255, and the fuel pressure gauge moves incredibly slow, i know that, but i havent actually monitored it to see if it visibly loses pressure after i shut the engine down. here's a FACT: when i...

damn... maybe you have a boost leak thats not causing fuel cut? maybe check those IC pipes over really well...? i'll keep thinking! -shaeff

TO THOSE OF YOU WITH AN AFPR!!! when you rev the motor, does your fuel pressure drop? the more i rev the motor, the more my fuel pressure drops, i thought this was because you're injecting more fuel into the motor, but it should (makes sense) that the FP should stay constant, right? so my...

:( sad to see you go, drake. it's really a shame that another mkiii member bites the dust... however, i do see where you're coming from. it's just too bad you couldnt store it or something. you had a nice car. hopefully we'll see you back here in the future, drake. good luck with your future...

heh, i bought my car from brooklyn. under the back seat i found .22 bullets, an old shirt in the back seat, nasty ass seat covers, about 10 different types of wheel lock 'keys', some razor blades, and a rusty ass knife. i think thats about it... -shaeff

just to clear it up, do the wires run to the top of the transmission? if so it's most likely for ABS. (i dont have ABS or an auto tranny, but i'm using an auto tranny wiring harness from a car that also had ABS, and i'm manual, so i just cut off those wires and coated the ends of them to prevent...
