Injector Pump out of spec should i even run it?

[wolf_walker]

Is it running hot at highway speeds? 
If so, it's not the fan that's the prob, though it should be on if it's really hot.

If it's just running hot when not moving and the fan isn't coming on, it's fan related.
IR thermo is good, test light to check the thermoswitch and straight wire the fan briefly to make sure it
works at all.  If you have AC, turning that on should kick the fan on as well.

Don't overheat it.  Bad juju.
And don't trust a stock gauge untill you've spent a long time with it, and only a little then.

pretty much just driving it on the street i sorta live in hilly area but just driving it like 40ish and then coming up a hill i feel its under powered like im at WOT in 2nd making it up but its not like really fast maybe thats just how it is for hills?

The fan works i jumped it with the battery.

Also the truck is an A/C truck but all the lines and stuff were taken out by Previous owner i did turn the dials to A/c and still no fan came on.

on the thermo switch is there a ground and a +? or could it be either one? maybe i have it wired up wrong. I was also thinking of just making a wire from the thermo switch + to the + on the fan and then ground the fan and ground the thermo switch to the battery warm up the truck and then see if it turns the fan on that way like bypassing all the fuses and fuse box would this be an option?

Yeah, the PO probably took out the relay needed to pass the juice to the fan.  It sometimes lives(d) on the fan shroud. Clue is no-fan w/defrost or AC.

I would proceed with the direct wire, as proposed.

On my latest 1.6TD acquisition after resealing the pump doing the waterpump and putting on a new belt and such. I timed it to 1.00mm exactly, where it was hard starting and smoked white once it did.

I feel that with the white smoke you probably need to retard the timing just a touch.

I would recommend adding one of them triple gauge setups, so you can accurately measure what is going on in there. On top of that, I like the idea of a an added fan switch so you can manually over ride the system for whatever situation. Me personally, I only have a manual setup on my 84 M-TDI.

so it really helps to have the correct wires plugged into the right spots. I figured out the radiator fan im gonna go drive it around the block it should come on now when it gets hotter

What chassis is this in again?

It shouldn't if the car is moving and air is coming through the radiator. The gauge will likely have to climb near 3/4 to turn the fan on.

 and it didnt! i was stoked it did come on though when i let it idle after driving it around so it all works im happy about that!

Okay back on topic now.

So here is how its looking the pump is 1.00mm and it smokes alittle white on start up but once it warms up i cant see any smoke while driving it and on WOT black smoke comes out and continues to come out til i let off the throttle and just cruising no smoke.

How should i go about getting alittle more power out of it? Or what should i do now? I feel that it can be tuned better it doesnt seem to idle completely perfect yet its alittle clanky.

I feel it should be able to take hills a little better and not be so slugish i can start a hill in 3 but then i have to go to that 2nd WOT to make it up and its just black smoking all the way ha

[8v-of-fury]

There is another two/three prong plug in the engine bay that fits on the radiator fan?

The fan works on a simple positive and negative.. Plug a positive jumper into one terminal and a negative jumper in to the other terminal. Fan turns on? Fan is good.

Where are you located?? Is it hard to start after it has sat over night?? What is your coldest yearly temperature?

A 1.6 Non Turbo will always smoke, its naturally aspirated lol. There is not much at all you can do for power, other than the Governor Mod.

What gearbox do you have in the truck??

If you are at much elevation above sea level and your hills are more than a couple of percent grade, you are probly just enjoying life with a NA 1.6.

If your compressoin is good, your cam isn't worn, your fuel is good, your exhaust is clear, your intake is clear, your fuel system is tight, your assorted static timings are right,
your injectors spray well, and your pump advances as it should (that one is of note), your brakes aren't dragging, your alignment isn't wonky,
and you aren't carrying a ton of weight, that's getting to be about all there is to a NA motor. 
People speak well of the gov mod, read up.
Otherwise save your pennys for a turbo if the truck is worth it to you.
One of the reasons I strive for ideals with these things, is without the turbo you got nothing but optimization left.
There is a marked difference between a NA 1.6 that runs "ok", which don't take much, and one that runs extremely well.
They are both slow, but the latter is enjoyable.  At least to me.  I've had both.
Trans gearing for your lifestyle/terrain is a thought as well.

I think personally if you put a (well) rebuilt pump on there and open the exhaust up you'll have a more enjoyable ride.
Assuming you aren't at 6K feet and trying to climb 7% grades and all the other bases are covered.

Its funny i wish i had a 1.6L i got alittle dinky 1.5L which probably doesnt make it any better lol but yeah i live at about 5k feet and i guess the hills are pretty decent grade atleast where im at so i should just accept i wont be making up them fast but more slow and steady ha.

So i guess i should just work on fine tuning the pump and should i stay at the 1.00mm or should i maybe try and advancing or retarding it some is Advancing might give me alittle more power but less fuel correct?

the truck is a little 1.5 NA and it has a 5 speed. I will look into this Governor mod!

[8v-of-fury]

1.5NA is the worst for power of the lot, 48hp at like 4400rpm. Which explains why you have to run the bag off of it to get up a hill.. 5000ft elevation doesn't help either haha.

With the white smoke on start-up its telling me you are a smidgen too advanced. Back it down a touch until you get the perfect cold start then you have the best setting.
