Hard Starts

[MidnightBlade]

Now that we are having mini blizzards here now and the temp is 30's-40's my truck will take around 30-40 sec of cranking (in 10 sec bursts) or a tiny shot of ether to get it to even fire . I put new return lines on last night and it didn't help anything, GP's are in good shape and I usually hold them for 12 sec when it hasn't been drove for a while.

If I drive it for 15-20 min and park it for 6 or so hours it won't restart with out a itty bitty shot of ether or about 40 sec of cranking

It has huge plumes of white smoke while it's cranking and a slight haze of blue when it first starts. Once it starts it will run rough for about 20 sec or so and then smooth right out. I don't know if I bled the fuel system good or not so any advice on how to bleed the injectros and fuel filter head would be nice.

Sounds like glow plugs or air intrusion. i would double check the plugs.

Yea, that's at the top of the "To-Do list" for now, should be able to check it tomorrow after work

X2, sounds like a bit of both to me. Is your cold timing advance working?

 

[bghnkinf350]

How old is the fuel system? Have you taken off the filter and seen how much fuel is in there before you start it?

 

[MidnightBlade]

IP and injectors have 5000 miles on them, lift pump I think is still stock. (154k)

No, I haven't taken the filter off yet

How do I check the cold timing advance?

If this just started when the temps began to drop, I'd be more suspect of the glow plugs. How does it act when the block heater is used? If it starts right up and acts like it did before when the block is warm, it supports the glow plugs as being at fault.

Read my tech article "thoughts on hard starts and air" but primarily check your glow plugs. White smoke means you have fuel, so I don't think you have an air intrusion problem. The rough idle is due to selected cylinders not firing until it has run long enough to have compression heat. There is no such thing as bleeding injectors or injector lines once the engine has started one time after such parts being disturbed.

NO!!!!

I am having a hard enough time dealing with the 50-60* temps right now. i don't want to even talk about snow. i asked my mom yesterday if we could just skip winter this year and she said that woul be fine.

Replaced my 4 month old Bosch plugs last night with 8 more of the Uhaul specials and it starts like a dream now.

Around 45* this morning, held them on for 7 sec and it fired off on the first revolution

Also Mel, remember how I had a slightly rough idle at the Rally?
I found the cause on Saturday when I did the return lines. The front injector on the passenger side was only seated finger tight . Tightened it up and she idle as smooth as ever now
