Ford - F150 :: 2003 V6 Slow To Start
Mar 18, 2015
2003 F150 V6 automatic 123K 2WD single cab long bed and yes....its white in color - so we all know exactly what we're talking about!
Occasionally it takes longer to start then normal. Battery is good, spark plugs are new. Runs great once its started. It turns over fast and everything. So electrical doesn't seem to be the issue but my guess is low fuel pressure or something.
Truck runs happy once started so I don't know that it would indicate a bad fuel pump.

This has happened twice in 3 years....I get regular service from a Ford dealer and am overdue.... I think it may be temp related. Has been below freezing the last few nights. Truck was parked on an incline during the last two "shutdowns" ( engine lower than bed slightly), I drifted to a level position and it started. This has only happened twice previously. Now it seems to be a permanent problem but I am unable to get to the dealer without a tow... which I am trying to avoid.

Occasionally my 2003 f150 takes longer to start than Id like. Lets say 2-3 seconds before it fires. It turns over plenty fast so Its not a battery crapping out. Runs great once it lights. I replaced the spark plugs but that didn't change it. Once again this just happens every now and then. 120k on the clock. Should I suspect a fuel pump showing its age? Oh, I should also note I changed the fuel filter a few months back.

My 82 f150 4x4 302 c6 trans is acting up. My c6 is slow to shift into any gear when I shift the column shifter, after a moment it jerks into gear, also it doesn't seem D is doing anything but all the other gears seems to function manually or auto.
Fluid level looks ok, maybe a little high on the dipstick. I'm going to check the modulator and do a fluid/filter change but looking for a link to the band adjustment screw ?

1992 Ford 150 4wd ... Starting sequence turns over very slowly when ignition is activated. Starter, Battery, Plugs have been tested. Spark has been checked and is active at ignition sequence. Could this be an amperage draw when ignition is activated due to a short in ignition circuit?

It's a 99 f350 7.3 diesel powerstroke. About 180k miles I think.
It cranks fine. I just changed the glow plugs(all were dead) but when you try and start from cold, it takes about 7-10 seconds to fire. The oil res is full, tried disconnecting the EOP sensor, still fires up and takes just as long. There is one near the oil filter, and that seems to not be it either.
Doesn't smoke, no oil leaks that I know of. Not sure what else to check before sending it to another shop to get put on a diagnostics machine. I read about the IPR, but it has no problems when running. Only problem is a very long time to start. Also changed the fuel filter.

I have a 2000 f350 7.3 got a check engine light that turns off when rpms go up and a slow start. My mechanic said that there were no codes being blown, what is going on?

I have 2001 F250 7.3L 261k miles.
Over the last few months, I have noticed that my truck is taking longer & longer to start after sitting for a long time (i.e. every morning, after work, etc.) When the problem first started (3-4 months ago) it would crank for 2 seconds & nothing so I would turn it off, let the "wait to start" light go off again (depending on outside temp 10-20 seconds) & then it would crank & usually fire right over like it was new. That seemed to happen only in the morning when it was 70 degrees or colder outside but no problem after work when it was 80+ degrees.
As the weather has gotten colder, it has gotten progressively worse. A couple of weeks ago, it was in the 40s in the morning & it took a solid 8 or 9 minutes of cranking for a few seconds, then trying again before it started. Once it started it did "chuga chug" a couple of times before it smoothed out. Last week when it was 16 degrees in the morning, it wouldn't start at all. I tried for a solid 15 minutes before I gave up.
I will say that as it has gotten worse over the last couple of months, I have noticed that it's cranking w/o firing but I will hear it fire once or twice per crank before it will fire up & run. Once it starts, it runs like a champ. No studders, stalls, slow acceleration, etc. Pulls like it always has. The weirdest part about it is that once it starts & runs for 30-60 seconds, I can shut it off & it'll fire right up every time. If I get it up to full operating temperature, I can go back & start it right up 2 or 3 hours later w/o a problem.
I did notice my oil cooler is leaking pretty badly (that will be fixed this weekend) & my valley has fluid in it but it's hard to tell if it's diesel, oil or a combination of the two because my truck is setup to run on WMO (waste motor oil). I have dual tanks so the OEM tank is diesel & the auxillary tank is WMO. I have 2 mechanical fuel pressure gauges on my fuel bowl, 1 pre & 1 post fuel filter as well as an aftermarket Walbro fuel pump. The fuel pressure when running on WMO has always bounced a little bit between (65-75 psi) but the fuel pressure on diesel has always held solid at 75 psi until recently when I have noticed that it flutters a very small amount between 73-75 psi.
I have verified that the GP Relay works & was leaning towards a glow plug problem but considering it was having troubles at 70 degrees ambient temperature, I'm hesitant to think that's the true problem. I think that might just be adding to the problem. I live in the south so my truck doesn't have a block heater but I'm going to add one this weekend when I replace the oil cooler gaskets & o-rings.
I'm also going to pick up a new Android tablet today (replace my broken one) so I can use the Torque Pro app to monitor ICP, HPOP & InjPW. Finally, I had a DP Tuner chip on it & to remove that as the possible cause, I removed it & the same symptoms continued.

I need fixing my 2003 f350 6.0 diesel, I have been working on this truck for a while and still am having problems, here was the original symptoms:
-Hard start or no start on a sunny day
-Rough idle for 10-15 minutes
-Rough shaking in the low RPMs (35 mph)[/COLOR]
-Slow response from the gas pedal
-boost would only get to 14
My dad and I then did many things to the truck in the shop, those things are:
-Air test and replacement of coupling going into oil branches (next to HPOP)
-Replaced EGR valve (no good)
-Replaced ICP sensor (leaking oil)
-Replaced ICP sensor and IPR valve piggtails (due to frayed wires)
-Cleaned Turbo
-Cut MAP sensor hose and reattached it (spliced on the end)
-New battery
-Performed a bubble test and found two bad injectors on passenger side (injectors #5 and #7)
-Cleaned and lubed tops of injectors
-Replaced O rings and copper crush washers on all injectors
-Replaced nipple cup O rings (tight)
-Blew out injector cups
-Bubble tested after injectors put back in (no more bubbles)
-New FICM, EGR cooler and oil cooler were already installed
-Ohm'd main engine wiring harness (good to go)
-Taped up frayed wires on fan clutch connection
-Increased wire gauge on the positive jumper between both batteries
-Sanded each ground on the batteries and engine, cleaned battery clamps, lithium greased connection points.
-Checked fuel for air (no air)
-Checked fuel psi (85 psi, plenty)
-Oil changed
After doing all of this (diagnosing as we fixed each thing) we now fixed many things including the hard/no start problem. Now, for the first three to five minutes:
-It starts right up
-Runs perfectly, no shake and instant response from the gas pedal and turbo
-Boost goes to 28
-ICP is 800-950 on idle
-IPR is 25-26.9% closed
After five minutes however:
-Starts to shake
-IPR % starts to raise
-Received no response from gas pedal (absolutely no power)
This truck has been torn apart like 8 times and I have to do it on my spare time.

On cold and/or wet days weak engine cranking. After a couple of attempts to start, I only hear a click about the 3rd attempt. If I wait about a minute or two, it still cranks slow but starts. Battery was replaced about 6 months ago. Electrical systems test good indicating no problem with battery, altenator, or starter. I don't seem to have any problem on warm days. My car is 4-cyl with about 85,000 miles and is kept in an unheated garage. Mechanic thinks trouble is likely the starter. Problem is intermittent, I'm not sure replacing the starter will fix the problem.

My 86 f150 will start great and run when cold, but when it warns up it won't start. I will turn over strong, but it just won't fire. I have replaced the ecm and the Icm. What else could it be?

256,000 miles. Started overheating as soon as the truck started up. Replaced the radiator and thermostat, and now overheats when driven over 40mph. (Does not overheat in idle or under 40). Everyone I've talked to says I've got a blown head gasket, but i DO NOT have water in my oil or white smoke coming out of the tailpipe.

Mechanics cannot find out why it occasionally does not start and has to be jumped off. If left not driven for a day walk out next morning try to start and it has to be jumped off. It only has 8,000 miles on it. 2013 Ford F150

I just put an '86 5.0 engine from an F150 2wd pickup in my '87 truck of the same model. The motor was running when pulled but when I set in the '87, it won't run. I've replaced coil, distributor assembly, plugs, wires, throttle body, checked timing etc. I've got spark through the plugs and fuel in the cylinder but with no luck. Don't know where to turn next.

Went to start "Larry", my 1990 Ford F150, the engine cranked but did not start. I switched to the other fuel tank and it started right up. The tank I normally use is the rear one and the pump had been getting noisier while it was running so I knew it would be soon to fail and it made no sounds when I checked it later to see if it would click and whir. I pulled the tank and installed a new pump. To test it I turned the key and heard the pump whir and stop. I turned the key to start and it started and died a couple ti mes. Front tank switched on and the truck started. While running I switched to rear tank and it died. So I have the pump in and it sounds like it runs up to pressure but the fuel is not moving.
Thought maybe I had fuel lines crossed but my manual seems to indicate they are two different sizes so that left me scratching my head... I have years of experience doing all my own wrenching but this is my first in-tank pump replacement. I have assisted a friend on a couple but never really wanted to pull a fuel tank and in my case this job required I remove the tow hitch set up as well. The hand pump for $9 at Harbor Freight was worth every cent as it made moving fuel to front tank a snap. So what the heck is happening? I don't see how a pump could be installed wrong, it is getting power on initial key turn...I should add the only time it did start I presume was because of fuel in the line that the front tank had supplied on previous start ups...

I left the keys in the ignition last night. I didn't think it was left on, but apparently it was. This morning when I tried to crank the truck, it wouldn't start. The dash lights came on, but it didn't make any sound. I tried to jump it off, and it still won't turn over. What it could be??
The truck that wouldn't start was a 97 Ford F150, the car I was trying to jump it with was a 96 Honda Civic. Someone told me that might be the problem, that the small car wouldn't give enough power to a truck...

I have a Ford F150 Triton Super cab that once and a while it will not start after a heavy rain. When I turn the key it sounds like I am not getting a spark or gas. Besides that everything comes on normal.

I have a 2010 ford f150. Every time I fill it up with gas it wont start upon the first try just turns over. Second time it sputters and then stalls.Third time it starts then runs and stalls.Fourth time it will start fine until I fill the truck up with gas again. I caught part of a Car Talk shop on Saturday May 25 about a gas fumes the new sealed gas tanks, charcoal filters. Didn't hear all of the program.I read some articles on the internet about a possible gas tank valve. What is the problem with this ford f150 truck to make it stall out after it is filled with gas???

Once I had driven for about 15 minutes and the truck set for about 5 minutes. Then it would not start. Another time, I drove for about 20 minutes and it cut off while driving in a parking lot. I have had 2 different shops take a look at it and they cannot duplicate the problem. They have run a bunch of diagnostics and tried their selves but it always starts for them.

Recently my 2001 F150 4x4 5.4 truck has been misbehaving by being difficult to start at random times. The engine will turn over with however will not fire. After some time, I am able to get it to fire. When this happens the truck start normally for the rest of the day and maybe several days. Around the same time, error codes for a variety of sensors would occur. This problem was traced to a broken PCM connection. When this problem does materialize, no error codes are generated. After some time in repair shop, a probable cause could not be found.
