just waiting for my computer to come back from jj and then going to look at the tps... i hope thats what it is... cant wait to get this thing going... i cant seem to get this tps tested... cant find any info on testing this thing? anyone know what i can do to do it properly...

thanks a ton JJ for the test.. but yeah hes right.. ruled that one out... not the ECU... so i guess its the sensors from here...

hey.. double checked the delivery date and it appears the package is supposed to get there on the 6th... which is tomorrow.. so hopefully we can get this put in and tested asap as i just sold my other ride tonight and dont have a vehicle ...

i tracked the package and on june 1st it says it was out for delivery.. hopefully you will recive it today if you havent recieved it in the past 2 days... ill try that tps check.. i do have a digital meter so we will check that..

hey guys... jj is testing my computer and all... i talked to a nissan mechanic and he said to try the tps.. is there any way to test this thing.. ??

awesome thanks 88.... JJ i sent you the computer today.. its gone... you should recive it like next week friday..

mines 5 speed.... 87 4x4 v6 5 speed...

What will FSM scans do for me.. and where are you gonna send them to...

http://media.putfile.com/Nissan-Engine-Problem thats the video for what the engine is doing.. you'll notice the reving.. thats me pushing on the pedal to keep it going.. maybe this will help..

you guys are awesome.. JJ send me your full address i'll have it shipped to you right away.. as well i have a video... if anyone would care to add me to there msn id be happy to send it.. ill try to put it on the net at a site somewhere...

i thank all you guys for your help.. its been great.. ive checked things i didnt even know i had.. haha.. but still no go.. but hey it will come.. im gonna try the injectors next.. see how that goes.. then maybe the throttle pos sensor.. see what i can do with that...

all these problems that people have been giving me are cures for idle problems.. for starters it wont run.. it sparks and turns over and if i keep pumping the gas it will stay running but like crap.. if i dont touch the gas after it starts it dies... i cant check vacuum and all that other stuff because it will hardly run let alone idle...

anyone know where i can pick up a used or even new maf??

see its weird because it wont stay running.. i have to pump the petal to keep it going... but when i unplug the maf it doesnt run any better.. the thing doesnt even run unless i pump the pedal..

hooked the timing light up to each individual spark plug wire and the light came on for each one.. so looks like there is spark to each of the plugs.. now its time to take the plugs out and set them against the valve cover to se if they park... could be a crappy plug.. but even if should run at least.. as well i dont know if my problem would come from bad wire resistance??? lost there?? i talked to a nissan mechanic and he said to first check the tps and the maf.. i cleaned the maf but didnt work any better.. also unplugged the maf wire harness.. didnt run any better.. am i missing something??? and how can i test the tps??

ok i tired the unplugging of the injectors.. keep in mind this model is electoinjection.. thats what it says on the top of the aircleaner.. so all 4 wires are connected to the same connection.. i poped the connection open and it was caked with a red brown liquid.. looked kinda like a wack load of engine oil.. so i cleaned it out and plugged it back in.. also there is a 2nd plug right beside this one that looks to be grounds.. i cleaned that one as well.. tried it and no go.. still the same ole crap.. although i did notice on the passenger side right by the fire wall in the corner there is a blue plug thats not connected to anything.. i looked for the other 1/2 but found nothing... anyone know what that goes to??its got 2 purple wires going into it and 2 black.. but nothing to plug it into.. NEXT STEP IS THE SPARK... gonna go grab a timing light asap... see how that goes..

so i pull the plug wire and connect the timing light to the metal iside of the wire and turn over the truck ans see if the tiing light flickers?? and do this for every cylinder?? Oh and i dont beleive the o2 sensor would be it.. i unplugged it from the harness and it still is doing the same thing.. its not idling rough.. it wont stay running!!!

it might be.. but when i had a bad ignition coil on my civic it wouldnt even start.. this truck starts just wont stay running.. next im gonna check the wires for spark make sure its not running on only 3 cyl.. haha.. and ill check the cap and coil from there... just wondering if anyone knows any easy way to do all of this?

thanks for that infor but i have tried the ecu many times.. even when it ran ok i tried and it came back all good.. normal operating blah blah... i dunno what it is.. i may have a lead with the previous owner.. he's kinda giving up info about the problems he had before too.. hopefully i can fix it.. i guess he replaced the cap and 2 wires of the 6.. all the wires look the same and in good condition.. but i did notice the screw on the rotor wasnt in all the way.. i have a new rotor but i cant seem to get the other one off.. i took out the screw but it wont pop off... it should shouldnt it?? im going to try the wires and coil next to see if there is spark.. does anyone have a easy way to do this??

ok i unpluged the maf sensor and it still ran like crap.. plugged it back in.. ran like crap.. i looked at the plate under the dist cap and its clean... when i aligned the 12 deg mark up best i could and took off the cap the rotor was pointing in the direction of #1 now i cannot see and arrows or anything to line up it perfect on 12 deg dont know where the mark went.. i just assumed that the arrow is center and adjusted it off center to the 12 deg and is was pointing in that direction... i was told its either sensor or fuel/carb problem.. is there anything i can check carb wise or any other sensor i can check?? i dont knwo how to check those other sensors...

i have a haynes and a chilton.. just really unfamiliar with timing. ill try that crank think again tomorrow.. and the dizzy wasnt totally loose... but if i used a bit of force it would turn... but like i said.. i went from the bottom of the adjustment to the top to see if it would get better either way but didnt.. one way made it rev nicer but die right away... the other way made it chug and try to stay running but would idle like crap when i stepped on it.. if anyone has msn messenger i can send a video clip of what the engine sounds like and all that.. pm me or add me at stikky_p@hotmail.com...

is it ok to look under the cap.. i dont wanna effect anything that im gonna hyave a headache getting it back.. i was told to leave the cap and rotate the shaft to see if that helped any... and it was a little lose when i twisted it.. but nevwer helped anything at all.. so i put it bacjk...

ran through a bunch of stuff again yesterday.. feels like im getting nowhere.. i think i might just start again from scratch of break down and buy that timing light to see where i stand.. of corse id have to have a friend to keep it running... btw will the timing light even work if its not constant.. if hes reving the engine up will the light work?? i may just end up riping the front off and checking the belt.. i have a weird feeling it might be that... hmmmm or injectors.. anyone know where i might be able to find a throttlebody for a 87 pathy??

by the way yeah the problem has slowly gotten worse... used to run fine.. then took a bit to get running but when was warm ran great.. then started running bad when warm too.. now it wont stay running...

thanks man.. as i get deeper and deeper into this things its annoying but fun... i wont let this thing win.. i have to cure its illness.. even though it has 300000kms....
