i still havin problems with my 1995 ford F350 powerstrok 7.3l. i bought it drove it home and put new stock injectors in changed the oil and fuel filter then started her up. she ran good at idle but soon as i hit the throttle it poured white smoke and had no power at all, so i figured it the turbo. i then got and had a new garret quick spool 1.00 housing turbo put on. when i went to go pick it up from my buddys house hu put the turbo on for me it would start and idle but soon as u put it n gear and push the pedal down it falls on its face and just dies. the only things done to the truck are everything i just said and dual stacks with straight piped exhaust 36in tires and 2 in lift. i dont know what to do to the thing since i got it nothing but problems. any suggestion would be greatly appreciated. everyone of my buddys and my girlfriends dad who works at thermo king said they think its the injection pump but personally i have no idea.

 

Your truck does not have an injection pump.

Take it somewhere else.

 

Why do u think because of white-smoke it would be the turbo? was it only when you got up to high enough resistance to where you were pushin boost that the whitesmoke came out? could be a head gasket? is the smoke kindof blue? and the smaller housing may cause the truck to overheat, especially since we have no inter-cooler's...

 

it dont smoke nemore just when i put it in gear and try to go it just dies. it falls right on its face

 

it does have an injection pump i had a dealer look at it and they told me to hook a scanner up to it myself before i have them charge me to do it and i thought it was the turbo because it had no power at all it would idle perfect but when i drove it down the road and back it wouldnt even climb my driveway which has little to no incline. i had to put it in nuetral rev it up and then let it settle put it back in gear and then it climbed the drive.

 

Powerstrokes have a High Pressure Oil Pump and a fuel pump.......the HPOP sends pressurized oil to the injectors wich actuates the injectors along with the electronics , the fuel pump supplys them with fuel, there isn't an injectin pump like on a cummins or the older 7.3's...Its called a HEUI fuel system..

Did you put in enough oil??? they take 14 1/2 to 15 quarts

 

Was it doing this before the injector install and the oil change?


This is what i was thinking too.. low oil level not enough to fire the inj properly

 

I had a 1992 gas suburban that did this. It turned out to be a fuek issue. It was flooding itself because it wouldnt advance timing. I know diesels are different. But it may be weak glow plugs. Is it a hard start before or after it falls on its face?

 

its always hard to start the glow plugs are brand new and it was smokin real bad before i put the injectors in cause one injector was missing an o-ring on it. and when i took it to the dealer they said it was an injection pump as well so idk if u know a lil sumthin they dont or what.

now i wondering if they dumb and i should take it somewhere else or just spend the money and let them fix w.e they are calling the injection pump. hmmmm.........?

 

Im not trying to be a dick, I'm just saying if the shop is calling it an injector pump and not a high pressure oil pump, it may be because they're guessing at the diagnosis, that's all.

First thing's first, I would check the fuel pressure.

I've had a couple 7.3 trucks in the last little while that were acting similar (although no smoke) and the little pickup screens in the sending unit were plugged up with this gooey black crap. I was actually getting ZERO fuel pressure on one truck under load, and 20 inches of vacuum on the inlet side of the pump, which is REAL BAD.

The longer the truck ran, the less power it had, and the worse it ran.

I took the sending unit all apart and I blew all the junk out of the screens, and BANG. 50psi fuel pressure and 0" vacuum restriction on the inlet side.

ALSO....when you hit the key, check for power on the OUTLET side of the glow plug relay. They are quite prone to failure, assuming you have the old "Starter solenoid" style and not the module type one.

You should have power at the outlet side of the relay for about 2 minutes
