fish biting?

i'll try the two stroke oil, though i was SUPER impressed with the stanadyne additive. i was setting codes as fast as i could clear them before the additive, but after i added it, codes went away, but hiccups and farts stayed....until now anyway. price between additive and two-cycle are about the same here, but it is worth a try. thank you!

They recommend both btw, FWIW you supposedly get back your investment in increased fuel mileage also.

Longevity of your lift injection pump and possibly LP too depend on consistent lube via diesel fuel additives to make up for the Ultra low sulfer. (the sulfer was very lubricating).
 
Matt how does the 2-stroke oil compare to running QMI Fuel treatment. I know the QMI does more only needing 6 oz per tank but I would think lubrication is more of an issue than water in the fuel.


If they do differnt things can't hurt to do both. See, Motor oil and 2-stroke are petrolium based and mix together molecularly with diesel fuel. Let me try to find some old research posts i've read before. Great reads, and can't emphasize enough how important it is for your IP's longevity.

Very good read indeed! Thanks for your troubles. It is interesting what each product added brought to the table. Thanks again!!!!
 
well, i took the pickup on a small trip last night. what i figured out, is that it is worse after it has warmed up, sits for awhile, and then run again. my best guess iss that when warmed up, and shut down, the OS has a chance to heat soak. when fired again, chugs, and farts. it only gets worse on the way home.



That is EXACTLY what mine did last summer. Does your truck code when you restart warm? Mine did and would then run great after sitting overnight.
 
does not code immediatly after restart, but cruising down the road usually. but yes, cold start in the morning always runs good. have you fixed yours? if yes, what did you do?

So I'm not full of crap, I'm not exactly sure. I DID drain the tank down to nothing and then put fresh fuel in and I blew out my tank sock. I did also put 2 new batteries in (on the same day) and I think that the old ones were giving me some weird trouble also. After the fuel and batteries, not one more problem and that was 6 months ago.
 
i already cleaned tank, and romoved sock. i put a fuel filter in line, and batteries start truck fine, i don't think they are bad. i cleaned and modified my battery terminals though.

Where did you put your fuel filter? I have heard data backed stories of fuel pressure starvation when factory lfitp pump is 'sucking' through a restriction (filter). It can push fine, but weakness sucking.
 
In normal driving a Heath h/o will pull thru a Racor pre-filter, you lose some flow if hitting it hard, or towing heavy, which is why I went to the Walbro FRB-5 so I'm fully fueling the IP at all times

I already had my Walbro installed when I had trouble. Lucky me.:sad:
 
i cleaned the optic sensor, took it on a trip, and same thing happened. so i am assuming, that a new IP is in order. can i buy an optic sensor, and if so, where can i get it?
 
Find a local Stanadyne dealer. I think thats the only source.

I am betting its the fuel metering mechanism/solenoid. Worn plunger or stop "T".
 
Have you tried chainging the engines Coolant Temp Sensor? Or at least try jumpering that harness with a 300ohm resistor to fool the PCM to think the engine is happily at 180 constant.

But you also have to lubricate the IP, throw in 1/2 quart of TCW3 2 stroke or SAE30 with your Stanadyne if you want to keep using that.

Also drain some of your fuel into a jar at the drain valve and see what it looks like, if there is any water bubbles, if it is dark, or if it is clouded.
 
thanks guys, appreciate the quick responses. the fuel is clear, and no i havn't replaced the coolant temp sensor. but on that note, when it's not hiccuping, or farting, it runs like a champ. and it only does it after it has been run and warmed up well, shut down for an hour or two, and then run again. even then, when it happens it doesn't always throw a code. when it does, it throws codes for optic sensor. could water temp sensor cause this? thanks again!
 
I would try fooling the PCM first with a cheap resistor across the harness. The coolant temp sensor can mess with timing and fuel rate and cause surging and stumbling.
