White Smoke raw fuel

[87TurboT]

I just changed the glowplugs & injectors. The truck is very hard to start now and smokes (raw fuel) severely.:mad: I can drive the truck and under full throttle the smoke goes away. I did notice while changing the injectors not much fuel if any came out the lines. The truck started good before the injector change, but would have raw fuel smoke for the first couple miles driving, then cleared up.:confused:

Hi Sounds like an air leak into the fuel system somewhere.Mine did exactly the same thing when i got it.I found two leaks that were the problem.Then i put a new IP and it had a leak so it was hard to start and smoked at start up again.Found that leak and got some Kenndy quick heat glowplus.Now the truck can sit for a month and start right up with vertually no smoke:)
If you keep looking you'll find the problem
