Hard starting when cold

[tschwab]

Truck sleeps in the garage where the temp is around 50 degrees, when I go to start it in the morning, it fires right up but I have to feather the throttle for a few seconds to keep it running, is this normal? From day one, I have always had to depress the throttle a little to get it to fire up, but now the throttle has to be feathered for a few seconds to keep it running on cold start-up. Once truck has been warmed up, it fires right up.



Is this normal?

Bad Overflow valve?

Bad fuel return line? I didn't think this affected the early '98's

Bad starter selinoid?? sticking?

????



Thanks

What is your idle speed set to?

Bill,



It is set around 850. The DTT TC really drags down the idle speed when cold. I usually let it idle in neutral for at leat 1 minute for the speed to build to 850-900 when cold.

I am in the process of trying to diaganose a similar problem.



Some feel it is normal, but in my case I know it is not. Last winter it would run on it's own no problem, but this winter it will not.



Here are a a few things I have on my list to check out.



-intake heater operation or possible air leak at intake heaters

-clean battery connections

-tighten and clean if necessary all connections associated with intake heaters

-misadjusted or starting to fail fuel shutdown selenoid

-fuel heater

-relays - check connections, possibly replace realys

-idle (mines ok and yours seems fine too)



These are just a few things I can come up with that may casue this problem. Let us know what you get figured out.

I would suspect the idle needs to be raised just a tad.

double checking

This is where I like my idle. Engine is warm. You guys should be close to this... in gear.
