Subject: Cold Start problem
IP: Logged

Message:
I have a 99 2wd v6 5spd Dak. It's very hard to start in the morning. It will crank quite a while before it even thinks about firing. Then when it does, it sounds like it's only firing on a couple cylinders at 1st, then it either stalls, or gradually picks up until it's firing on all 6. This problem 1st appeared about a year and a half ago, right after I changed the bypass hose. It only happened occasionally then. It would go for as long as 2 months without doing it. It's gotten more frequent over time, and now it's pretty much a daily thing. It only does it in the morning. It always fires right up in the afternoon, no matter how long it sits during the day (been putting in some 12 hr days lately). I thought it might be the coolant temp sensor, but replacing that had no affect at all. Any help would be greatly appreciated.

GP sounds like you have a fuel problem, try turning on the key to turn to on the fuel pump 3-4 times before you try to start, if that helps it could be losing pressure over night.If it doesn't help, I'm not sure what it could be, I'm sure others here can help you though.
Good Luck

want to add
if i read this right

#1 only after sitting over night?
#2 or long periods of sitting?
then it acts up

#3 has never done this or acted while driving or during short periods of sitting?

if you answer yes to 1 & 2
and no to #3

then i would suspect a leaking or leaking injectors

try running a bottle of fuel system cleaner and a injector cleaner with a full tank

after that tank full is run through wait a few hundred then do it again

Thanks for the replies. Cycling the ignition key a few times was one of the 1st things I tried. I've also run a few different brands of injector cleaner though it in the last year, most recently some Lucas stuff about a week ago.

The truck has 196,000 miles on it. The engine otherwise seems in pretty good shape. It burns no oil since I replaced the intake plenum cover gasket back in May. I thought maybe that would have some affect on the problem, but it didn't. I also replaced the O2 sensors after I did the gasket, but that shouldn't affect a cold start anyway.

It will do this after sitting overnight or longer. In other words, if I get home friday night, don't use the truck at all Saturday, and go to start it Sunday afternoon, it will still do it. During the week, it has been doing it every morning, although not always to the same degree. I've had it sitting for up to 12 hours during the day, and it doesn't give me this problem in the afternoon/evening.

As far as once it's running, it never gives me any trouble. It's never stalled on me. A couple times immediately after it has done this it's acted like it had a fouled plug, but as soon as it's up to temperature it runs fine. Once in a while when the problem is at it's worse, I start to smell raw gas just before it finally fires up.

Something else I forgot to mention... I used to have a check engine light on. The code was for cylilnder #4 misfire. I changed the plug on that cylinder (they were all new about a year ago) with no luck. I bought an injector, but before I could change it, the 7 yr old battery went bad. I replaced the battery, and guess what? No more check engine light, so I returned the injector to the parts store. I've had the check engine light come on 2 times since I replaced the battery 2 months ago. Both times it went out before I could get a code scanner on it (within a day), and - get this - both times the check engine light was on, I didn't have the cold start problem.

I'm sooooo stumped!

Those 'codes' should be still stored in the computer - hook up the scanner , and see what it says. And quite possible # 4 injector is leaking.

GP you know!... I just recently have almost the same problem with my truck, it wont run or keep on idle after seating 8 hrs or 6hrs eider overnight. I got to give gas to keep on idle and after drive 1 or 2 blocks it will be fine. I checked my fuel pressure and it was fine, I spend hours on line reading forums and finally found my problem, it was the idle air control (motor) that its located right begin the throttle body maybe yours its going bad, it could be, mine was gone, the plates on the throttle are close when ur engine is off, when you start your engine the function of the IAC is the motor pull the pindle to get air, so ur engine has to keep on idle without you stepping on the gas. So i replace the IAC and cleaned the throttle body and now my truck starts and runs @ the first crank.

I hope this can help you!....

Good Luck!

Roberto, thanks very much for the reply. I don't think we have the same problem though. Mine will idle once it does start. Also, if I open the throttle while cranking it, it doesn't make a difference.
I also don't believe it's a leaking injector because even if the truck sits for a week, it will still exhibit this problem the next time I go to start it. If it was a leaking injector, I would think the fuel would have evaporated in a weeks time. Also, if that were the cause, why does it start right up in the afternoon?

GP, how old is your battery? try cleaning the battery connections and maybe get the battery load tested.

Hey, just to let y'all know (especially Mr. Knowitall who was so sure it was leaking injectors), the problem turned out to be a bad coil.
