Ford Super Duty (1999-2016) :: 2002 F350 7.3 - Cranks Good But Hard Start?
Jun 3, 2015
Dealing with a 02 f350 7.3 powerstroke . The engine cranks fine . It fires but won't start smoke coming from exhaust while cranking and firing so seems to have good fuel . When it does start it misses for a few minutes and blue/white smoke . When the miss ends so does the smoke and starts fine after that and runs great until it sits for 12 or more hrs . Then back to same start issues . Fresh oil ,new glow plugs, new cover gaskets , glow plugs test at 1.3 ohm across all 8 of them , no voltage drop through glow plug relay , good voltage to each glow plug when tested right at glow plug terminal on each feed right at glow plug , fuel filter housing stays full doesn't seem to bleed back , high pressure oil pump pressure test was high enough to trash a 1000 lbs gauge in 2 to 3 revalutions of engine when cranking . Tested at presure sensor port .

OK, I have a 2002 F350 with 160k miles that cranks fine, but has a hard time starting when it is cold. By cold I mean that it is not hot from being driven in the last 5 hrs or so. No problem starting after being at rifle practice for 3 hrs or after a trip to the store. Always have trouble starting in the morning, like this morning when the temperature outside was 49 deg. I have to crank for quite a while to get it to turn over, but once it catches, it runs like a champ. Afraid I'm going to wear my starter or batteries out because It seems like I have to crank for about 2 minutes.
I have a fairly new CPS replaced less than 15k miles ago, new glow plugs, and recently replaced the leaky bleeder valve on the bowl. This difficult starting condition came about some time before the bleeder valve seal repair, and is still doing it after the repair. This problem seems to have cropped up on it's own unrelated to any work I have done. I am using Mobile 1 5W-40 diesel oil. When the no start occurs, there is no smoke present out of the tail pipe like what you would get if you had bad glow plugs. There is just no fuel getting into the injectors.

My 2011 f-350 6.2l cold starts hard, it cranks through 2 cycles sometimes before it fires, then it might stall. Sometimes it stalls if I put it into drive or reverse before its warmed up. It has also misfired on one or several cylinders during startup. It has also misfired while driving. It has never stalled when driving. I have replaced the canister purge valve, I have done a full tune up with all factory plugs. All with no change to how it starts. My next step is a Pcv valve, I have one coming from ford today.

My 1999 Ford F350 V10 will crank forever but will not start. Seems like it isn't getting fuel.
Here are the facts.
Truck 8 months ago was used by my brother.
When he got back 2 weeks it sat then truck wouldn't turn over. Thinking it was a bad battery I charged it But then I let the truck sit 8 months.
I put the battery back in and when I started cranking it the gas peddle felt floppy.
SO, I realized I was out of gas. I went and got 5 gallons.
I turned the key on and off like 5 or 6 times and then tried to start the truck.
The Pedal is NOT Floppy anymore. It has pressure like the gas is back in the line again.
But the truck will crank and crank and crank without turning over. It won't even try to turn over.
The truck has a brand new Fuel Filter in it that was put in 3 months before my bro used it so it worked after that was changed.
I assume maybe it can be the Fuel Pump but WHY would that go bad from sitting and wouldn't the Floppy feeling in the Gas peddle STILL be in the pedal if the pump was bad??

2007 6.0l cranks but no start. Read all the forums and I think I performed all the checks. Getting a ficm/ cam sensor/crank sensor no sync. I'm also getting 84.70% at the ipr while cranking. Do I have multiple problems? Watched videos on either the ficm or ipr percentage but not one that had both problems. Getting injector clatter and fuel pump runs. Didn't see anything obvious with the harness.

Shade tree mechanic, new to diesels and new to forum. I have the dreaded 03' 6.0 F350. It cranks over strong but will not start after its warmed up. I went to Auto Zone and they gave me the following codes: P2291, P132B, P0672, P0402, P0284. Once it's started it runs fine.

i have a f350 superduty with a 7.3 turbo diesel and I pretty much hafta keep it plugged in to get it to start, i have installed all new glow plugs and both relays have been changed and the problem is still there, only other option i have not tried yet was changing the pcm controller but unsure if that is the problem ..

I have a 2002 F250 7.3L and it wont start. Its been sitting for the past few days in the cold because the batteries were shot but was plugged in the whole time. I replaced the batteries today and even poured diesel 911 5 hours before trying to start it in case the fuel was gelled. It cranks fine but just wont turn over.

2002 F350 7.3 intermittently wont start after I've shut it off, it runs fine but sometimes won't start when it's (warm)? Wait hour or more and it starts right up.

I pulled the battery cables this weekend to install a flatbed on my 02 f350, I did do some welding on the frame of the flatbed during install and the bed was in contact with the truck frame which is why i removed the batt cables in the first place, now after my project is finished i have reconnected batts only to have my gauges bounce around and an audible clicking under the hood when I try to start, gauges bounce back and forth several times, odometer comes on slowly.

I have a 2002 F350 with a V10, this just started happening where at times the truck will turn over but won't run... after a few times of trying to start it I pull the key out let it sit for 5 seconds then put the key back in and runs perfect..... now at the gas station the other day it started but ran like it was on 4 cylinders... I turned it off and restarted it and runs perfect. Heading to Kansas next week to pick up my boat and don't need problems....

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.

I have a 2002 f-250 7.3 diesel, i straight piped it but only by cutting muffler off and welding a piece of pipe in its place, it is pretty loud but id like to hear the turbo more like more of a whistle, it has a pretty good whistle once i get past 1500 rpm, is there a slightly bigger turbo i could put on without putting too much strain on the 180,000 mile engine?

I'm in a real jam because my work truck won't start. 1999 F250 7.3 Diesel 157k mi. - Air and fuel filters were replaced in the last 500 miles. This pup ran fine when I parked it last Wednesday before the holiday.
Checked for start last night because I'd been having battery issues, Both were replaced the previous week. It's cranking good but just won't start, not even a bit. No wait to start light, oil level is good, can not get obd reader to link.

On my 2002 7.3 liter for the last about 1 week it has been getting harder and harder to start. Up until yesterday when it will not start at all. What it does is this. A week ago I noticed it cranked slightly weaker but still ran perfect once started. This has progressed slowly but definitely. It has never gotten better, only worse. Even with jumper cables hooked up it does not improve at all. The starter is a Carquest POS but only has 50 thousand miles on it.
I have driven hundreds of miles with this problem in the last week and the truck has never skipped a beat aside from the starting issue. I took the batteries in to no less than 3 places and they all said the batteries are good. However when I put my multimeter on them when it is being cranked the volts drop from 12.6is down to about 8 volts. When I did get it started the other day and put a meter on it the batteries were charging up to around 13.7 or so.
When there is no load on batteries they show good but have been unable to get a solid answer if any of these places are load testing them: I am convinced they are not. I checked the resistance of the cables and they all have none. The grounds are all good. So I pulled the starter and took it in as a last result. They say the starter is good also! The connections were all tight and I cleaned them all very well.

I just installed a new positive cable set for the dual battery's and the starter checks out good.

On my 1999 F350 SD Crew Cab, 6.8l V10, it will crank, but won't start. I have checked fuel pump fuses and relays, and all are good. I checked the "collision switch" and it is good. I pulled the fuel pump and connected it to the battery and it works, but there is no voltage at the fuel pump connector nearest the fuel pump. I have spoken to a Ford mechanic and he said that if their is voltage from the output of the collision switch, that it must be a wiring problem between the switch and the fuel pump connector, but I have but I have been unable to find a problem. Anything else to try?

Had truck engine detailed a couple of months ago. Looked great, ran bad. Plugs were wet. Checked the codes, dried the plugs in the cyls that were missing, started running great. Don't use the truck much. I had left the code reader attached and it ran the battery down. I was away from home, so I had AAA jump it. Let it idle for an hour. Took it for a drive, it ran great. Stopped once and it cranked great, started right up.
Stopped again, but did not shut off the engine, went to take off, it bogged down, no power and stopped. Would not start again (full tank of gas), but cranked really good, and fast. It acted like it was getting just a little fuel, so I think at this point it's a fuel problem. I don't hear the fuel pump come on when I turn on the ignition. I tell the whole story because I am wondering if something under the hood could have gotten wet? I think it's all dried out, but?
My plan is to spray some starting fluid into the intake and see if it starts to confirm that it's fuel. If it is a fuel problem, what then? Is there a fuel relay? I know there is a fuse but I haven't been able to get to it yet (alarm horn bolted above it). The holidays and work of course are putting a damper on my troubleshooting. If I have to pull the tank to change the pump, how do I empty the tank? 99 F250 V10....

My 2002 F-250 v-10 sat for over a month with me in the hospital for spinal reconstructive surgery. Battery was dead but has been charged and tested as good. The truck cranks strong but will not turnover. I am unable to do other diagnosis, what might be the problem.

I don't drive the truck much anymore but over time my MPG has gone to total crap...about 10mpg around town...and that's baby-ing it.
Now it suddenly takes many cranks to finally start on a first start. (cold or warm days)....

I have a 2003 F350 6.0 King Ranch. My first diesel truck. Bought it in March 2016. One owner with 102000 miles on it. Has a Bullet Proof oil cooler and 4 inch exhaust. Truck ran great until a week ago. Now, under any hard acceleration it blows out blue/gray smoke and does not seem to have as much power. Coolant level is constant and I cannot find any traces of water and oil mixing.
