Well guys got home the other day ,retarded the timing a little ,adjusted the throttle cable got every thing so it sounds about right .the only problem iv got is that my truck starts great around town on short runs,but if I take the two hour trip to work she's hard to start ,untill she's cooled...
Its a thought ,my pump has a cam and arm for what I believe is the advance,I'm thinking this is early type.
Iv messed around with.the bosh rotary fuel pumps a bit and iv changed the rotor &head assemblys out for larger ones from bigger capacity engines to gain performance
Can this be done with...
Yep sounds like a plan,am I right in thinking turn the pump body against the engine rotation to retard the timing?
I'm pretty sure timing is the issue the old girls only making about half the power that she used to have,
I'm back home in a week so I'll experiment and see what I come up with...
Thanks will
I timed the pump using the referance lines it starts really good cold,produces a bit off fuelly smoke for about a minute then its good,has a fair bit of combustion noise,wich it never had befor,,I'm thinking I might retard it a little as it isn't great at starting hot ,the pump...
Could my timing be to far advanced? Would this cause the stutter,as the timing advances at high rpm .also when I hooked up the electric advance,cold start device on the top of the pump it didn't make any difference,it is activating ,but I read somewhere you can really hear the difference,iv got...
Thanks guys
The tank filter was done not long back,I used 3/8 fuel line to suit the filter that I had,the injectore pump was of a 6.2 it's been turned up to run a 6.5 so it's pretty standard inside,don't get me wrong I don't drive at 3500rpm, I try not to go over 2000rpm I'm like driving miss...
got a question you may be able to throw some light on ,iv recently done a DB2 conversion on my 98 6.5
Massive hassles with the tranny until I got a quick 1 TCM
Any way iv noticed the od power spike when driving in town ( iv only done a couple hundred Klms since the conversion)
The engine will...
Well guys,purchased a quick1. Controller from leroy diesel ,very promt service, the package was hear in a week which is good for our part of the country!
Was very easy to fit,
Had a run in with a intermittent power supply ( my fault for not testing it properly) and my tps caused a little drama...
Yes l have thought about that but nobody over hear wants it I'm not going to bother jerking the ESS out it can stay there iv got to tcms ones a recon with no E prom the other the same 16196390 its complete probably be flat out getting the postage back
No dought it can be made to work,all you need is time ,a commodity that I just don't have,I thought it would be easy did the research ,got the parts found it hard to find the correct wiring diagram but nether the less proceeded with the project
It didn't work ,could be something simple might be...
Leroy was right
Got more problems than I can shake a stick at,and my biggest worry is reliability can't afford to be away from home and have a electrical fail,it would be more than the trucks worth to recover it,
It was worth having ago at but this time I'll suck it up and move on!
Thanks for...
Yeah I'm not going to be drilling no holes in stuff ,my tranny was good before I swapped pumps ,
I'm half way trough the wire up ,ended up pulling the harness of the tranny and proving each wire just to make sure,the. Diagram I'm using is for a 94 G. Van with. 4l80e ,I'm starting to wonder if...
Iv found a g van TCM scematic and I'm hoping to do a overlay that on to my 98 schematic and come up with a diagram that works
Sorry about the whole hummer hummwv thing I do relise there is a difference ☺️
This is what I found guys
Whether it will make it run is a different question ,but I'm hoping with a fair amount of tenacity and a good splash of desperation I can make it happen
Like I said before there are three mode wires on the tcm,I'm presuming that's a military thing also iv noticed on a...
No dramas.im hoping to have a win with this.
The only thing iv noticed with the hummer tcm is that there appears to be a tranny mode switch ?? No dought there will be other differences .ill see if I can stick a screen capture up or somthing
Thanks mate
Having a job finding the correct diagram ,found something through auto zone ,one for 95 g van 6.5 with 4l80e it shows tcm connector numbers but the wire colours will be different I'm thinking on my 98
