Ford - Mustang :: 1971 - Cold Engine Start Fine But Will Not Start When Warmed Up / Sluggish Crank
Jul 31, 2014
A cold engine crank will turnover and start normally. But stop to run and errand or grab lunch...and the warm 302 2 barrel engine will turn over very sluggishly, lke the battery is dying. If you wait until the engine is cool, an easy start is assured but that takes hours! A local repair shop has rebuilt the carb, the battery & cables are new, and the starter works fine when engine is cold. My local repair shop is out of suggestions. It seems to work a little to hold the gas pedal down on the floor for a warm engine start....but engine still turns over sluggishly when trying to start when warm. Now If I drive it.....I just drive it around town a bit then back home ...unless I stay several hours somewhere while the engine cools....but that's not fun. It is a convertible, fun to drive...and this problem needs to be solved.

Is this a warm stall issue and if so what is the actual solution to it ?
- Car is warm it will stall out at times after start . Giving it some gas will save it from stalling
- When dead cold it will have a very sluggish start
New plugs and coils. New fuel pump fuel filter & regulator . New crank sensor . Throttle body cleaned as well as maf. evap leaks all sealed up too. battery is good too
Very frustrating. Only solution would be to leave it at a shop for at least two hours so they could do live scans. But I'd rather not pay two hours of labor for nothing.

I have a 1971 F250 automatic with original stock 360 engine (100k miles). It currently has an Autolite 2100 2bbl carb.
The Autolite is leaking gas out somewhere where I can't see the leak. It takes a lot of cranking for it to start after sitting 10 minutes and my wife won't drive it for fear of being stranded. My attempt at a rebuild must have failed... Also have issues with anti-stall dashpot spring coming off while driving. When the spring and plunger come off I have to hold the gas on a little to keep from stalling while stopped at a light. A couple other parts looked like they needed repair during the rebuilt, but the kit didn't have any replacement (vacuum diaphragm torn). Also, after replacing plugs, plug wires, replacing points with Pertronix Ignitor 2, a new rotor, and distributor cap, it still doesn't hold a steady idle. In fact it is hard to get it down to the spec idle for an automatic without fear of stalling.
To make a long story short, what is a low maintenance 2bbl (new, not rebuilt) replacement carb. The truck needs to be dependably started by my wife for garage sale runs and home depot trips. I could switch to a 4 bbl intake, but would rather wait for another 50k miles and switch the engine over to a rebuild 390 with nicer intake and carb.

So 3 times in the last 2 days, my car has needed a jump start. Took it to pepboys and they told me to replace the battery, a new battery later, my car wouldn't start again and I needed to get it jump started again. Took it back to pepboys, they say everything checks out fine including the battery and the alternator and that it should work fine. This happens to be exactly what they said the last time.
The car is a 2012 Ford Mustang V6 convertible.

1992 Ford Mustang 5 spd 2.3l 4 cylinder. So a couple weeks ago, i got into my car and tried to crank it. I got one click then nothing. That's what I get whenever i turn the key. Not the repetitive clicking when the battery is low. After I found another ride home, I did some research and determined that it was probably the starter solenoid. I took a trip to Autozone and replaced the solenoid, but when i tried to crank it, one click then nothing. In order to get my car out of the school parking lot, I popped the clutch and got it running. Now, I'm stuck as to what the problem could be. I'm thinking it might be the starter itself, but it might also be the ignition switch.

When engine is cold it starts fine, when hot from driving (e.g. the engine's temperature display's needle is in the middle) i cannot start it unless i try 3-4 LONG keys. What can it be? Where should i start?

This morning, for the first time I can recall, the car would not start right away. Had been sitting in the garage for 2+ days. Starter would crank just fine, but engine would not fire. No lites were left on overnite. Finally (after about 6+ attempts), engine started -- runs fine now.
Took it to TOY dealer. Their diagnosis: weak battery, alternator low output.Happy, had recently (6 mos) replaced battery after 4 years of use, so got a new battery N/C.TOY ran a charging system check and it shows "Alternator Condition: OK" (midway between shitty and great I recall).
Funny, but my first thought when it would not start was the fuel system (fuel pump) or dirty ignitors. I did ask my regular mechanic for an opinion, and he thinks it might indeed be the fuel pump -- perhaps a clogged filter.

I'm TSing a no-start on my 2005 6.0L F250. Engine cranks fine. I've been working my way thru the TSing guide and using my new ScanGaugeII. No codes found. At glow plug warmup, (dash light goes off), I'm getting 40.5v FMP, 11.0v FLP, 14.8% ICP, and 0psi IPR. After cranking for 10-15 sec, get 35.5v, 10.0v, 84.7%, and 446psi. I've had a trickle charger on all night to keep the batteries charged. Have not seen FMP over 45 or IPR over 470.

I have a 97 f150 with a 4.9..... I drove it less than a half a mile and shut it off. when I got back in it to start it up it wouldn't do anything like the battery was dead but all the electrical worked but it would not turn over. after about 4 hours when I returned, it started just fine. drove it straight home and shut it off and immediately tried to start it again and had the same issue. What the culprit may be ?

Simple question: Is it possible that battery problem/corrosion in battery cables would allow car to crank but not start on first try when cold? (Car normally starts on 2nd or 3rd try). I've read some places that if car cranks its not a battery problem but I'm not convinced.
Background:I have a 98 Ford Mustang (approx 140,000 miles) that occasionally has trouble starting. Car normally takes 2 to 3 tries to start first thing in the morning or if it has been sitting for a while. It always cranks but doesn't turn over. I had it in the auto repair shop, they said it had to do with IAC valve being stuck open. They recommended to replace throttle air by-pass valve. The repair was done and when I came to pick up the car I heard it take three tries to start before they brought it to me from the back. I asked about it, so the service advisor said he would go and talk to the tech, he said he talked to the tech and that there was a lot of carbon that he had cleaned out and maybe remaining carbon in the system caused problem, I got the idea that they seemed to think everything was fine if I had any problems I could bring it back. The car became even harder to start, now taking up to 8 tries. I brought it back and they said that the new IAC had to be adjusted to allow more air. I picked up the car, they said it was fine, but now it still takes 2 to 3 tries to start it first thing in the morning.
In the past, I have had trouble with battery and battery terminal corrosion, have had new terminal ends put on my battery a few times, last time was probably about 6 months ago. Terminal ends look very corroded again. I'm thinking about just asking them to replace the battery cables and see what happens.

Replaced battery. It seems to crank fine and I can definitely hear the pump kick in for a couple seconds at first, but just will not start. It sat for several days in cold weather. Based on what I have read here I am thinking it is the fuel pressure, and that I need to get the tool to check that. There is about 1/4 tank fuel now, it seems that once before when it sat for several days around 1/4 tank it started and ran rough, then ran fine after I filled the tank. Could it be as simple as filling the tank?

Okay so my 2003 Jetta GLI normally starts without a problem. But it seems like whenever it gets cold (below about 40) it doesn't even try to start. I turn the key and nothing happens, the engine doesn't crank. All the lights turn on like normal and they're not dim so I don't think it's the battery. It'll still start if I roll-start it, but there isn't any sort of hill for a few miles. Normally once it warms up later in the day it'll start up.

My Lexus Rx350 (2007) having problem starting the car when the engine is cold or switch off more than 1-2 hours. I need to crank the car at least 2-3 times to get the engine run. Once the engine run, i have no problem restarting the car with a single crack.

It's done this a couple times now. Both while raining out/high humidity. Prior to this, I could hear the pump "growling". Sounded like maybe starting to go. You could hear it prime when opening the door or turning the key forward but would stay sounding like that even when the car was started. Without the radio, you can hear the pump running.
1st time- The car will crank without issue but never start. I let it sit a few minutes, turned key, heard it prime,tried again, started right up like there wasn't an issue and I couldn't hear the pump this time while the car was running.
2nd time-The car will crank without issue but never start. I let it sit for an hour, opened door (couldn't hear prime), checked fuse 28 (good). Figured wth, let's try anyways. Turned key, couldn't hear prime, started right up. WTF. cold idle normal (1000-1200rpm), light revs to 3000 ish normal. Turned off car, let sit for a minute. Turned key, heard prime, car started without issue and I couldn't hear the pump again while the car was running.
My dad is thinking to replace the pump right away. Is there anything else to try? The relay is working... at least sorta. With the somewhat intermittent issue, where to start? Either way, relay or pump, I will be replacing fuel filter.

My 2004 Buick Century is parked outside, it starts up fine and runs fine every morning and anytime it sits for a period over an hour in any kind of weather including minus 25 degrees. Sometimes when I shut it off for say 15 minutes or half hour and then go to start it again it will crank over fine but not start up. I can try several times, same thing.. But then if I leave it alone for maybe another half hour and try it again it starts and runs fine. also no warning lights etc. It's like something needs to reset itself. What is causing this ?

I recently caught up on some maintenance with my truck, changed the turbo pedestal seals, replaced both batteries, brakes, e-brake cable etc and installed new 10k hid headlights. its a single cab 250 with a 7.3 and zf6 4x4 with 133k. a couple days ago I turned on the headlights and the truck died, restarted no problem and would die the next 5 times I tried to turn them on, then it worked fine. yesterday I got in my truck to leave for work and got no wait to start light, no glow plug chatter, no fuel pump running. turns over just fine but no fire.
I got a ride to work and tried it when I got home, fired right up. I pulled the pCM, checked it out, no weird smells and my TS chip wasn't corroded or anything like that, worked fine. drove to 711 to get a 6 pack and it did the headlight thing again. I removed the HIDs because this all started after I installed them and reinstalled my silvanias and it didn't die when I turned them on. this morning went to leave for work, same no start condition. I disconnected both batteries for 30 seconds to reset anything and same problem. I was about ready to light it on fire this morning.

My brothers car is a 2000 VW Golf 2.0 that recently started starting rough in the morning, when the motor is cold it will struggle to even turn on and will act like its only running on like 2 or 3 cylinders for a second and most cases stall, he is having to pump the throttle to get it to even stay cranked until it all sudden just starts idling fine and it idles perfect but still acts boggy if you try to rev it right away as its warming up, after about 10 seconds of it idling the motor can be revved perfectly fine and you can turn the car off and it will start back up immediately..

My girlfriend has a 2003 f150 4.6lt pick up its a great truck most of the time. Problem is when the temp gets in the neg double digits it becomes very hard to start it cranks fine but doesnt want to fire. When it does fire it might stall a few times before it stays running. The last cold snap we had I replaced the battery and in the summer the starter got changed. I have heard that this model of truck are known for hard cold starts. I am just wondering if this is true and any other thing besides block heater. It is strange that my 89 gm pickup will start no matter what temp and I'm having problems with the newer truck.

This 1996 (220KM) car will run fine (perfect)for about ten minutes from cold (I'm talking -5 C)then starts to misfire when warmed up. Difficult to pull away (automatic) from a stop. Sound like its missing on two cylinders. Really chunters.
Installed new plugs, wires, cap, rotor, coil,filter. Don't know what to check next. Car will work at speed but I can feel it missing. Gun it and it will go. Doesn't appear to be a fuel problem.

2002 Excursion, 7.3L 375,xxx miles ... As the weather is cooling off, my excursion has a starting problem for a few years.
Replaced all the glow plugs last year. We (my brothers and I) thought it was injectors, but in the summer time or if block heater is plugged in, she starts normally and idles smoothly. And no smoke and runs fine once she warms up.
When cold, it acts like 1 or 2 injectors are not firing. Have run all kinds of cleaners through the oil and fuel.....
Don't want to swap injectors just to swap parts. Would like to diagnose problem....

I love my '86 Mustang GT convertible. Currently at 106,000 miles and running strong. The problem is searching at idle. I have replaced every sensor that me and my mechanic can think of. New plugs and wires along with rotor and distributor cap. The engine will start searching, i.e. idling up and down, and at time stall. If I apply slight pressure and idle up to 1,000 RPM the searching stops. Hard to do sometimes as this is a stick.
