    Mitt:
    been trying to find something that allow me to record both audio and video. I would use my laptop and a webcam but my lappies out of commision as well lol. (stupid toshibas and crappy dc adapters)

    Also on a side note does anyone have an known working ecu for a 3s-fe they are willing to part with for free (minus shipping costs). Im not sure it is that but wouldnt hurt to check.

    your going wayy to far into it ...Has the car ever run right ???

    Have you pulled your plugs ?

    Have you set and checked your timing correctly ??

    If not..Do these things and let us know

    you guys are getting way too intense on this. is this a usdm motor?
    ya know it may actually be the opening circuit relay. jump the fuel pump and b+ in the diagnostic connector and see if this resolves the problem.

    first this post is not in anger lol sorry if it seems like it is :p

    86gtscaged:
    i haven't had the engine professionally timed (IE with a timing light. for reason see posts above.) I have it based timed tho and it should run fine with that just lack some power. it has for the past 2.5 weeks anyway.

    I have checked/replaced the plugs several times (more for ruling them out then anything else.)

    as far as has the car ever run right, yes it has been running for 2 months before my timing belt decided to be old and strip teeth and for the past 2.5 weeks after the timing belt was replaced (yes i did it myself).

    i do own a haynes manual its thanks to that i have accomplished so much lol.

    Mafix:
    yes its a usdm 3s-fe, engine has 170k on it. doesnt leak fluids, ect. I will try the jumper thing tonight.

    to clarify i know where the b+ pin is but is there one for the fuel pump and if not what do you mean by jump the fuel pump?

    another thing i will be trying is removing my cat, as a freind thinks it may be clogged.

    i will post the results of all that later tomorrow morning around 2-3 am.

    oh snap...does the probelm occur near 3K rpms?

    it dies out if i rev (and hold like trying to drive steady but in neutral) it close to 3 k yes. it will also die out if i let it idle too long or if i rev/let off/rev/let off/rev.

    it honestly sounds to me like you have the timing off 1 tooth. those FE motors are an absolute whore to time right.

    you could have the timing light timed correctly and still have a cam or crankshaft off a tooth, that would still show the spark plugs firing at the same time as the crankshaft but 1 tooth would cause one of the cams to be a 1/8 forward or backwards.

    makes since.

    i could see that as well but i havent jumped any teeth as ive check the belts timing when i installed the new distro. and it was aligned correctly. (i made sure my lower pulley notch was 0 and that my top pulley (cam?) was on the upper stroke and 0 (tdc) i used a paper clip *as per the haynes manual* to check proper tdc.

    I will check again tonight though and see what that brings.

    also i can rev it up and it runs great till it decides to die. (had to drive like formula 1 racer to make it back to parking lot yesterday and was keeping it @ 4-5 rpm whole way and it actually never did anything till i got it back to parking lot and let it idle a bit, altho i know thats prolly a shot of luck as it has died plenty of other times @ those rpms/gears.

    well if timing is right i say fuel pump or opening circuit relay. jump the pins on the connector and drive it and see if that works.

    dont fuel pumps usually just die tho, i dont think i have ever heard of one working and then stopping, and then working again.

    no it may not be supplying the correct pressure.

    i had a jeep cherokee, that the fuel pump was going bad, though it never died on me it would caugh sputter and back fire at idle or low rpm modes and then you stomp on it and it would pick up and go, primarily because the vacuum effect of the fuel being used would pull fuel through the pump, but when there was a pressure in the lines it would weaken out.

    read the new sticky in diagnosis. fuel pump test is just finished.

    do they sell this as a kit? and if so anyone know prices i should expect to pay.

    thinks he should open a shop lol. i have more tools, parts then i know what todo with these days:p

    i can tell you once this is fixed if i dont already own these things i am buying them.

    a timing light
    a fuel pressure/injector testing kit

    you really don't want to know how much money is in my tool box.

    I am tired so i am going to double check the timing markers again tomorrow but i think they may be off :S

    i may just realign the whole damn thing just to be 100% sure.

    k going to bed will mess with it in the morning.

    okay checked the timing and its fine (base timing that is).

    now your not going to beleive this and i havent tried it so not sure its the fix but kinda makes sense. i noticed this morning (by pure coincidence) that if i barley turn the key my car fires right up *instead of taking forever to start like normal*. i was talking with a guy i work with (used to be a mechanic is now a system admin, odd career change huh) and he says there is a box under my dash (close to steering column that controls the state the car is in (on, off, ect). he thinks that is loose.

    so i will check that saturday as i will be here for the next 2 days since i have no car/no way to get home.

    that is odd, i dont think there is a box under the dash like he is refering to, but there is something similar and it is possible that it is loose between the key cylinder and the connector for the wires(on most imports the back of the key cylinder goes right to the individual wiring harnes wires)(american cars such as the mustang have a rod slide that pushes on a little box that has different contacts in it i.e. run start acc, that box can get loose and bad more easily than an import one) however try starting it then wiggling the key around(without turning it back wards i.e. in the off direction) if you can get the car to stumble by wiggling the key then i would say that very possibly the problem
