My car's been taking 4 - 5 seconds to start on a cold start recently. Could the starter be going out?

If the starter is cranking the motor normally it is not the problem. Sounds to me like weak spark or some other ignition issue. Maybe the coil or the ICM? Has the SES light come on? You might want to have it scanned for codes.Tracy

My wife's old Blazer (2000) was doing that a couple months before we traded it in this year. It had 70,000 on it. I swapped the plugs and wires out. Solved the problem.SOLD: 2002 Trans Am WS.6 - Black on Black - 6 Speed

If it is cranking normal, but not starting up, then possibly fuel pump related (or the check valve in the fuel pump).Comment

My car did that when the timing was off. So I would guess if not your fuel filter/pump, probably something in your ignition system like the plugs and wires as suggested above.1999 Ram Air Trans Am. M6

My car did that for a few months, then when I was 90 miles from home the fuel pump went out. Time to replace it."No, officer, that bottle is my onboard Halon system"Comment

It's not my fuel pump. I had it replaced in October. My SES light did come on once a couple weeks ago and stayed on for the ride home. I started it up again after that and it never came on again. It cranks fine it just takes a while for it to start. I'm having my plugs and wires redone soon with a new opti. Hope that will fix it.Hercules

Do you have a fuel pressure gauge? If the car is not maintaining 25-40 psi at rest, then it's the pump. I put a gauge on mine, and just before it went out, it would go from 40 psi to 0 psi in like 5 seconds after you killed the ignition. What will happen is that the check valve that maintains fuel pressure in the car will break, and any pressure in the line after the car is cut off releases into the tank and dries the line out. So when you turn the car on, the pump is trying to pressurize the line, but the fuel is just pouring back into the tank. So it takes like 3-5 seconds for it to get enough pressure to start. After that the car runs fine, and even if you refire within like a minute or two of shutdown it starts fine. If the car runs fine while driving, refires easily within 1 minute of shutdown, and can still spank non-boosted Mustangs with ease, then it's the fuel pump."No, officer, that bottle is my onboard Halon system"Comment

It could be your fuel filter. To figure out if it's fuel related just turn the key and leave it on, but not start for a few seconds and then start. My fuel filter was bad, but I didn't know it, and it did what yours is doing and I just got in the habit of turning the key leaving it on for a second and then starting, now even after replacing the filter I still always do it. Just try it, it will eliminate one thing.Comment

A filter problem would show up first when demand was high, like at higher load conditions. Pressure drop from a plugged up filter wouldn't be as evident at start-up when flow is minimal.Originally posted by CocaColaEatsPieComment

Did you replace with a walbro? I did. Mine did the same as yours after a month or so. Just started cranking slow. I think I have a weak pump, but I've yet to test fuel pressure.Originally posted by DJ Taso

Easier way to test it........just cycle the key a few times before you crank the car. If it start right up after cycling, then its probably the valve in the fuel pump....even if its new, its still a possibility.
