Slow to start

Lately I've had a few slow starts. More so when the engine is cold. It will crank just find but then its just a little slow to rev up. Drives, accelerates just fine. Just those slow start ups from time to time. Any ideas???

 

Already had the battery checked. Checked good. I get under there and take a look at the alternator. Thanks for the advice

 

I had a similar issue with my RAM.

Turned ignition truck would start would take its time to idle/rev up sometimes a little rough. Weather condition did not matter. That lasted for about 3 months
Then starting issue evolved into turning the ignition once, let it crank for a few seconds. Stop and on the second attempt
it started with no idle issues at all. That lasted for about three years. Then one day it would not start at all. Replace fuel pump.
worked like a champ. One crank truck started and no slow idle. Month later junked the truck bought new Tundra.

Mine does this as well. I live in south Texas and dosnt get that cold here. Do you have the flex fuel engine? I've heard you might have to get the ecu flashed. Keep us posted

 

How cold does it get where your from in Texas? Mine does this when its cold, it seems like it takes about a second or so to kick up the RPMs on a cold start. I also experienced this after disconnecting the battery for a while and reconnecting it and starting it but after a few starts it back to normal. Easy thing to do is to check, clean, and protect the connections.

By "slow to start" you mean the engine is hesitant to start, or the RPM's are slow to get up to where they should normally be for a cold start.

 

North Texas Wichita falls. Cold doesn't mean cold to me. Was stationed in South Dakota at one point but not with this truck. And I'm referring to slow to build rpms. Usually just first crank in the morning. But yes it is the flex fuel engine

 

you say the battery was checked...did you only check the voltage reading or did you load test the battery as well? just a simple voltage reading can/but won't tell you the battery is on its way out or bad.

 

Idk. Whatever AutoZone does for free. Lol. I don't own a battery tester or a multimeter

 

what year and whats the mileage?

nvm 2013
, just noticed your signature

if all they did was hook up a little hand held, more than likely just a voltage check. Should be able to go to a Goodyear or any automotive place like that, they should be able to load test it without any issue. Even Walmart automotive section might be able too.

Here's a good test:

Turn the key to on, but don't start, then off, then on, then off, then try to crank. If that solves the problem then your issue is the fuel pump having trouble priming.

 

Will definitely give that a try. Thanks for the advice

 

I remember reading somewhere on here about the flex fuel engines and cold starting ( could be wrong ) something about the ecm thinking it was running e85. Mine only does this sometimes, takes a second it seems like to idle up.

 

Yeah it doesn't seem to be an issue. Like I said it starts everytime, runs like a champ. Just slow to idle sometimes

 

Is our fuel pump a gas tank drop? Or is there an access under the seat?

 

That's what I figured. Thanks fellas! Any guestimates to how much it will run me to have this replaced?

 

Yeah im good with doing it myself prolly. I'm sure a buddy from work would help. I'll just have to put up with the Yoga smack talk cause they are helping me fix it.

 

My slow to start has turned into an every now and tben fail to start. She will try and crank but no fire. Sounds likes it not getting fuel. Second crank starts and the rest of the day it starts fine. Just the first one in the morning. No codes or lights thrown though.

 

Uh...For how long?

 

Makes sense. My driveway isn't very sloped but I got some ramps. I'll try it out. Thanks man!
