Hey guys. i just went and put new stage 2 injectors and hpop pump in my 1999 f350 4x4. In the directions it says youll see alot of white smoke when you first start it up because of all the raw fuel. I let the truck idle for 15 20 mins n it was purring. made sure everything was tight and no leaks then got in a was driving it to get all the raw fuel out like what the instructions told me to do. It was going for about 5 mins and then it seemed like it started to misfire no cel on or anything. So i pulled in to my driveway and parked it. it idled real rough so i shut it down. I followed the instructions to the t so i know it cant be the injectors or the pump. it seems like there is a gremlin. Before i bought the truck someone put a chip in n took it off. I checked to see if there was any blow by and i didnt. I did a oil change on it fuel filter and glowplugs i also took the spring out of the fuel bowl fuel filter because powerstrokehelp.com said that its a easy performance mod.i think i might put it back in tomorrow just to see if it does anything. Im trying to find someone in around kent ohio that would have a scanner that could help me do buzz test on the injectors to see if its a idm problem or valve cover gasket problem. Any suggestions on what else it could be cps? idm? ipr? any tests that you could think of for me to narrow this down and get her on the road again.im really confused how it idled fine and then didnt when i drove it. Any one around here that has a scanner n could help me please.

Thanks Dan

 

It will take probably 50 miles or so for the air to work out of the oil and fuel systems. Maybe that is all that it is.

 

Run it hard for a good 50 or so miles. Get all the air out. Do you have tuning at the moment ? Also don't listen or do anything else powerstrokehelp.com says or does.

 

the spring dose not help at all. it wont hurt to leave it out. but the air can take some time to get out.

 

Did you throw a straight edge across the injectors to insure they are all seated properly?

Did you TQ them to spec?

Did you use new injector O rings and coppers when installing them?

Check to insure you completely seated and plugged in all your injector plugs, and the UVC harness, both on the outside of the valve cover and inside.

Is the IPR nut on and tight?

Plug clean and tight?

What spring did you remove from the fuel bowl? I am assuming you did not remove the FPR spring?

As was said before, take everything you have ever seen or heard on that guys page and delete it forever from your memory, he is about as sharp as a round peg.

 

If you want to trust power stroke help? Just listen to him try to explain the "VOLCANO EFFECT" in a 6.0 on his video clip, that should cure you, but it sounds like you may just have a bit of air still in the system it takes a long time to get it out, but I would still check the harnesses on top at least what tuning are you using to support the single shots?

 

I will delete everything from my mind from powerstrokehelp lol. I did use a straight edge i did torque them down. i will check the harnesses to make sure there on tight the ipr nut is on and secured. The new injectors came with new o rings and copper washers. i didnt run it hard at all because of how rough idle it was. kinda scared me since i havent messed with diesels before i am ase certified so im not a joe smo you know but diesel are my new thing and im just neverous. i have a 6 postion chip that i havent installed yet because rosewood diesel and beans injectors told me to get my ecm or pcm which every you guys call it reflashed since someone put a chip in n removed it. They say its still "burned" on the ecm. the only thing is is that i have to take my truck to the dealership to get it reflashed but i have to go to the bmv to get my title transferrd to ohio and they have to do a inspection on it and i gotta get it echecked too. also my temp tags went and expired on me. I know all the injector wires are connected but im gonna make sure the harnesses are tight too. csipsd what do you mean by Plug clean and tight? you mean the ipr plug.

 

Any more details about your injectors? What does Stage 2 mean? Where did you get them? Did you change your HPOP with a modified unit? If so, which one did you get? I think you will need custom programming for single shots (if that is what you purchased...)

It is possible that the previous owner reflashed the PCM with a non-stock program so beware. It's also possible the previous owner change a lot more than just the programming so you really need to be careful before upgrading injectors. What brand is the 6 position chip that you are planning on installing? Is it a custom chip? There are several tuners that will be able to re-flash your PCM back to stock programming if that is what you need.


Meanwhile, first things first....
Are you sure all the electrical connectors are on each injector? It's super easy to knock the metal locking clips loose while reinstalling the valve covers and the engine will idle perfectly....eventually the vibrations cause the connector to fall out and the engine will run poorly. I would check this first before you spend any money on parts that might not be faulty. A multi-meter is your friend...

Good luck!

 

I am not sure about the 99 model but my 03 is factory split shots...If that is your case then to run single shot injectors require special programing....it will run but have a very rough idle...

 

Oops! I was thinking single shots and typed "split shots". Thanks for pointing that out. I corrected my original post....

I am wondering if the OP installed single shot injectors. Not sure what "Stage 2" is but I think it means different things to different people...

 

Sounds like you had your PCM reflashed for your single shots. If so you need to take it on the freeway for about 20 miles, ten @ way to get the air out like said. After that time if all else is good it should pur like before. You changed the HPOP to so the drive is important. Chet

 

I got the injectors from beans performance. Beans Diesel Performance - 94-03 Power Stroke 'REMAN' Stage 2 Fuel Injectors (Powered by CubeCart) i got the hpop from http://www.dieselsite.com/1994-20037...alinehpop.aspx and i got a chip from 7.3L <I>Power Stroke</I> Chip . I havent put the chip in it yet because i need to reflash the ecm. I am going to take the valve covers off tomorrow to see with the metal clips.how is the multimeter my friend. i tried doing a ohms test. Now is the 5th pin from the front power? i think i heard that on here somewhere. and the next two on either side of the 5th pin is that the glow plug wires. because i did a ohms test on them on the passanger side from the front to the back 1 pin nothing 2 pin nothing 3 pin 8.5 4 pin 8.2 5 pin power 6 pin 7.2 7 pin 7.5 8 nothing 9 nothing. on the drivers side from the front to the back 1 pin nothing 2 pin nothing 3 pin 5.2 4 pin 5.2 5 pin power 6 pin 5.0 7 pin 5.0 8 nothing and 9 nothing. what do i do now, im hoping getting a scanner tomorrow to do a buzz test. if a genisyis can do that.

 

According to the link you posted you ordered single shots. When you ordered the TDP chip did you tell them about the new injectors and HPOP? You are going to need a custom tune to utilize the parts you installed. It is possible you have the correct tunes on the chip but only you (or TDP) would know for sure.

 

To me it sounds like he has not re-flashed his PCM or corrected his tune to account for the single shots...

 

You do NOT need to get your PCM flashed because you installed a chip at any point... When you install the chip on the PCM it over rides the PCM programing, when you remove the chip, your PCM is back to stock...

Stick the chip on, its running like crap because your running single shots on split shot tuning.

It will white smoke, run rough, be very touchy on the accelerator and just not be much fun...

Install the chip.
