car takes a while to turn on when cold

[lasergt35r]

i have checked everything and car wont start when its cold out what can it be the car is all stock

Have you had your battery checked out? Usually the cause of that.

Won't start as in it won't turn over or it won't fire and run.

 

[lasergt35r]

it takes atleast 15min to start it has a new battery could it be the fuel pump

Sounds more like the coolant temp sensor. I would first test it with a multimeter and if it test's good than test the wiring.

I would be looking at the coolant temp sensor and/or wiring too.

+2 For coolant temp sensor. Same thing happened on both of my Lasers I've had. Plus for the cost of $20 normally, it's one less thing to cross off the old dsm part that's bound to go bad during your ownership.

thanks i have not checked temp sensor i will do that right now

the coolant temp sensor is good i noticed that my wires going to the temp sensor look very old

15 minutes? Can you explain the process it takes to start? Is it consistent?

Do you crank for a short while, wait, crank more, wait, crank more then wait until eventually it starts?

i have been having this issue myself. if anyone could shine some light on the issue would be helpful. I notice mine will crank but wont start. after i do it a few times it turns over then back off. i disconnect the fuel rail and it turns over for a sec. after i reconnect the fuel rail it turns over and back off. after 2 or 3 times of doing this it finally stays on but takes a while to build up pressure and i get a low throttle response. This only happens at a cold start though. Could it be my sensor too?

That sounds like a fuel pump or relay.

I have a similar problem. On cold starts I have to crank for 6-7 seconds, but once it's warmed up it will start right back up (e.x. after running into a store.)

I have a feeling that my fuel rail is losing pressure. Reasons unbeknownst to me, yet. I'm sure a search through the forums will turn up an answer.

Ive search and turned up nothing so far. some say could be a sensor issue others say i just need a bigger fuel pump with a regulator. My friend says it could just be my injector seals are faulty and im leaking pressure but i checked and havent seen any leaks around it....any ideas??? i wanna get this issue fixed.

I thought that cold starts are normal with dsms?

Or your fuel filter is clogged

Ive also read that if you have an aftermarket FPR it takes it a few extra cranks to get it up to pressure... My car will crank over then start cold after about 5-6 seconds, but be very rough @ about 400 rpm, I turn it off and back on then voila, runs normal.


Sounds like a pump or clogged filter though if your car is mostly stock.

Edit, forgot to mention mine is caused by a Fuel lab afpr

I always had that trouble when i was starting to loose compression, but it never took that long to start. maybe 4-5 min in the middle of winter.
