    Fuse Box Electrical Fire ( almost)

    so this is interesting, i bought used UBEC with all the plugs. identical truck with 80k miles. i pulled the plug to swap pins and wouldn’t you know it the exact same pin is melted!!! this has got to be a factory issue. the question is how do i improve the wiring to never have this problem again.

    Fuse Box Electrical Fire ( almost)

    is there a special tool i can buy to remove the connectors wires from one plug and transfer to a new one so i don’t have to splice the entire harness?

    Fuse Box Electrical Fire ( almost)

    that make a lota sense. this truck sat engine less for a year and the fuse block was in a box of parts. lots of opportunity for contamination/ dirt to get in there. i never really thought twice about it. just hit it with the air compressor and dielectric'd everything on assembly. the...

    ya i thought the N5 was the cause also but could find that right schematic for it ( thank you) i did use the wipers the time i drove it before this, about a hour into the mountains to go camping and back. this last time before the meltdown was just a errand run and no wipers.

    Fuse Box Electrical Fire ( almost)

    So i have about 6k miles on this engine and its been running great. i drive it mostly in the tow tune with my slide-in camper on the truck and no issues. its been sitting for 3 weeks and i took it to run a few errands, made 4 stops and then home. park it and head inside, all normal. i...

    code p02a1 (injector 2 leaking) runs smooth, HELP

    well i didn’t see chevy1925’s advice till after i adjusted the flow rates. local shop owner let me use his snap-on scanner, made it real quick and easy. i checked balance rates with the scanner right after and #2 was still at -4 and then slowly climbed to -7 which set the code. i shorted...

    code p02a1 (injector 2 leaking) runs smooth, HELP

    ok. i’ll try and track down a shop with the equipment to change the codes. i’m hoping to take this truck to utah for work on friday, is this a bad idea with this code popping up?

    code p02a1 (injector 2 leaking) runs smooth, HELP

    re did the compression test. most tested at 395psi one tested at 390 and one at 400. i have a feeling that HF adapter doesn’t seat very well though. tuner says tunes should have no affect on balance rates.

    code p02a1 (injector 2 leaking) runs smooth, HELP

    ya i’ve had a couple moments like that on this build. i filled it with new diesel yesterday. i was thinking about shorting the fuel system and letting it idle through a gallon of high strength 1:1 cleaner and diesel. sent results to s&s. they haven’t been very responsive.

    code p02a1 (injector 2 leaking) runs smooth, HELP

    tested ohms of all injectors at ecm plug. tested #2 several times and got different readings till i improved my testing method (sewing needle with alligator clips) the last 3 times i pulled needles out then reset and tested 0.5 onto the compression test redo. would a dirty injector...

    code p02a1 (injector 2 leaking) runs smooth, HELP

    which pins should i be testing against each other in the ecu plug. there are fuel injector supply voltage 1-4 and fuel injector control 1-8 looks like injectors are paired 1/4 6/7 2/5 3/8 which pair of injectors get which voltage supply?

    code p02a1 (injector 2 leaking) runs smooth, HELP

    hold up. i just reread 2004lb7’s directions. those results were at the injector harness feeding back into the ecm. not from the ecm into the injector.

    i get the same 1.3—1.2m ohm on the other harness plugs. i have batteries disconnected. should the ignition be on for these test?

    when testing plug to ground i get 8.5 m ohm then it slowly, but consistently goes down. s&s says .3 ohms

    code p02a1 (injector 2 leaking) runs smooth, HELP

    just tested resistance between injector pins it bounces between .4 to .3 ohms. on the harness pin to pin i get 1.3 mohms

    code p02a1 (injector 2 leaking) runs smooth, HELP

    i used the HF compression tester, but i just pulled one GP at a time tested the cylinder then reinstalled and moved to the next one. should i re-do it hot with all the GP out ? i had a charger on the batteries

    code p02a1 (injector 2 leaking) runs smooth, HELP

    code is only for #2. on compression test, engine was warm to the touch but not hot. i just cranked for 10 sec then checked the gauge. i took a video of the graph bar (wouldn’t let me post) but it stops right at 40 on the ohm test. i’m a little lost. should i be testing between the pins on...
