this was a progressive problem that has now gotten to the point where it won't drive any more . . . Tossing randum parts at it has now gotten uncost effective . . . Mike

Some how i highly doubt the plugs have much to do with it as since the tune up it logged in 1,000 trouble free miles :dunno: Mike

I forgot the brand of plugs but i haven't pulled them since i installed them . . . It only idle rough once its acting up when it stalled in the video ? i could of shut the key off wait 5-15seconds fired it right back up instantly it would of idle smooth again . . . It would rev out perfectly 3-5 time then go right back to bogging out . . . When i'm watching the fuel flow from the Injector while reving it up i notice the fuel flow fading away not increasing . . . Mike

:hijack: can i do that ? :dunno: i guess so :hijack: OFF track: "Video" I don't know about an HD remake but i have lots of awesome Videos on my you tube account some of the 2.5er some of the Studebaker 6x6 and tons & tons of ATVing videos and so on . . . Do subscribe n snoop around . . . ON track: So i just simply fire it up and unplug one unit at a time, the unit that causes no change in its operation is the bad part or parts ? Mike

Not sure i never tried it . . . Mike

:dunno: I have no clue :dunno: Mike

:ack: Wonderful, i don't have a gauge of that style :wall: it its a round dial gauge with a valve stem looking end on it simulair to that of a tire gauge I got it for use on my 92' GM 350-TPI & 95' Ford 5.8L-MPI :mad: . . . Useless for a TBI engine i see . . . Mike

Where is the fuel port in this thing ? . . . I have look all over it and i can NOT find the Tire valve stem looking deal for checking fuel pressure that my 5.7L GM & 5.8L Ford had . . . buddy of mine said i should be looking for a tire gauge on it looking unit as the other 2 unit had . . . I saw no such device :dunno: I'm stuck at home :fs1: time to crush it ? :dunno: ? Mike

Video: http://www.youtube.com/watch?v=U04poevHoWU this help ya any ? New parts: Cap Rotor. Plugs. Wires. Coil. Fuel filter. Fuel pump 1,500 miles ago. Mike

:wall: I'm down i'm down :fs1: i got nothing more then a fast idle, i made it about 100 yard's that was all she wrote ! :mad: I limped home at 2.5mph jerking and bucking the whole way :hmm: i did take some video after i got the heap back home for ya :thumbsup: :yes: processing now, i'll add as soon as it goes live :smart: Video: http://www.youtube.com/watch?v=U04poevHoWU Mike

:bowdown: O2 sensor :D . . . Bloody truck . . . Injector, fuel reg, I/M, O2 sensor . . . Mike

:clapping: that's what i must do :smart: Parts replaced as of yet: Cap/Rotor/wires/Plugs/Fuel pump/fuel filter/Coil Ignition Module tested-Good , but was told with it being intermittent could still be the problem. parts left: Injector / Fuel pressure regulator / Possible I-M. oh yea and a bloody alternator :fs1: can't catch a break :wall: oh well i guess :dunno: Mike

Possible fuel pump ? . . . Now that would truely suck, there aint but maybe 1,500 miles on the fuel pump and maybe 500miles on the fuel filter ! Sounds like a possible murphys law kinda thing ? LOL maybe its time for a carburator ? ;-) LOL 15psi ya say ? No fluctuations allowed ? Mike

For the giggles of it i pulled the air tube off and watched my injector spray fuel . . . at idle it was a nice heavy mist, at wide open throttle the engine bucked and stumbled only hitting 3,600rpm and the mist thinned way out to almost like a vapor thin . . . Injector related ? or Fuel pressure related ? the idle spray looked good as it reved up the spray thinned out . . . Module tho ugly tested fine . . . Mike

Ya I guess so, But i drive it every day i have no choice but to keep driving it . . . So I was wondering if it would show anything being intermittent . . . I can't wait to get my tires and it would be awesome to have it running good when i get my tires ! Mike

Diesel MJ, is it Doggy ? . . . I had a little truck with diesel once it was doggy and took it forever to get it up to speed . . . Mike

What suck's is i thought i had this thing fixed so i went and ordered up two brand new 235/75R15C Crowler MT's for my truck :fs1: . . . Mike

I will give that a try, because it didn't have to push it simply dropped right on . . . Mike

85-95% of the time truck run's perfectly, its an intermittent malfunction if it was the Module failing intermittently would the test show anything ? Mike

Question ? how tight is the coil pack supposed to be in the Ignition module ? Cause my coil had no resistance it simply just dropped in . . . the module looks corroded the whole casing of it looks rough . . . Mike

You guys sure love adding parts to the list . . . LOL oh well I'm happy with it ill keep fixing till its fixed LOL I'm not giving up ! Mike

Swapped out the coil with a nice new unit ! Ran great for a while but it stumbled yet shockingly recovered on the way home today ! What to replace next ? Ignition Module ? Or Fuel injector ? Both look old . . . Mike

second coil, was the right shape but the wrong unit, but after three trip's i got myself the right coil for my truck . . . $85 later we have a coil that fit's and the engine run's so all is good . . . I let it idle for about 40min then took out for a nice drive kinda getting on it and so far it ran smooth and steady as it should, truck seem to run alot smoother now not as much shake & shimmy to its idle . . . Mike

I was going say, the coil part they handed me looks different then the unit on my truck now . . . It has 2 big round plugs on one end and coil spark plug wire to cap connection point . . . Mike

:clapping: Wonderful :idea: hopefully i can limp it back to parts store . . . Mike
