I just bought a 02 F250 7.3L diesel last week.. Its not my first Ford but my first diesel.. awesome truck

Anyways, both yesterday and today a problem arose. I came out from a store and hit the remote start on my truck.. it cranked but wouldn't start 3 times in a row. The truck should of been warmed up since I was only in the store for about 10 minutes.

I jumped in and tried manually starting it by turning the key.. just crank but wouldn't fire. I got out and popped the hood.. checked the oil.. fine, listened for the fuel pump, pretty sure I heard it, checked a few other things.. finally got back in and it started... after I left the ignition on for about a minute. (Glow plug light went off within the first couple seconds and it was about 75 degrees out),,, glow plugs and relays are new.

From there on out, it worked fine. Same thing though happened again today, came out of a store (5 minutes) hit the remote start,,, crank 3 individual times but won't start. I previously have been using the remote start and haven't had a problem. Evenually, it did start after about 5 turns of the key.

I did a process of elimination here.. I think I have an idea but what do you think. CPS is brand new (with in 3k). Fuel filter is supposely 3k old also. Water in fuel is good, I'm almost positive I hear the fuel pump,, same noise I heard when it did finally start.. heres what I think maybe the problem..

I have remote entry on the truck. The passenger door lock does not work and just the other day, the drivers door works sometimes but recently not so ofter. I still manaully lock the doors but still hit the lock button on the remote to trigger the alarm system. I hit the unlock button when I want in but I have to manually unlock the doors. Both times this no start has occurred, its been when I used the keyless entry. I was thinking when I go to start the truck, maybe the alarm system is still on and is preventing me from starting the truck? I actually took the battery out of the keyless entry just so I would stop hitting the button.. maybe thats my problem but I'm still doubtful

The only other thing would be fuel related.. my guess. I just dont want to be stuck if this does it again and really wont start at all.

I also have a Superchip hand held tuner from my old 99 F250 V10. I was going to sell it since I have a DP Tuner on my diesel however, I was wondering if I could use the superchip as a code scanner.. since the superchip has it built in?? Of course I wont use the tuner end of the scanner but just for scanning codes? Would it work?

Let me know. Thanks in advance!

 

Not sure if the scanner will work since it's made for a gas engine. Try it and see if anything pops up.

As for the no start, go through process of elimination. Disable the alarm and remote start system and test. If you still have issues, next step would be the IPR. You'll need to watch ICP pressures to check this. Low ICP/High duty cycle during cranking means the IPR is sticking. Superchips scanner can't monitor ICP, even the ones made for PSD's. You'll need a diagnostic tool or take it to a diesel shop.

 

Okay, I'm going to first start with the alarm/remote system. Its only happened twice and not back to back with in the last few days... both times when I used the remote start. I'm going to use the key for awhile to start it.. and see if it still does it.

Would there be any other possiblities besides the IPR? Would like a couple options in case I do get stuck and atleast I know where to look.

Thanks.

 

That's the same direction I was thinking, Curtis. might another possibility, though, be the ICP sensor itself?

I have observed some similar starting issues with my truck, but only when I shut it down, and then try re-startign fairly quickly. If it sits for a while, there's no issue, whihc makes me wonder about something under the hood doing a better job of letting me start it up when it's cooler. The sensor is not mounted inside anything in the engine and may just be acting up when hot... or would that also show some problems while hte engine is running, too?

Just a thought.

 

Okay, I took my superchip tuner and hooked it up to scan codes.. it worked.. I pulled quite a few codes..

Going off of my service manual I obtained the following..

P0381 - Glow Plug Indicator Light Malfunction

P0470 - Exhaust Backpressure Sensor Circuit Fault

P1212
Anyone know what these last two are?? I can't find anything in my book
P1211

The next number down which did not show in the on OBDII Scanner is P1210 which is High Pressure Oil Pump Pressure high condition.. like I said, thats the next one down on the list.. then it skips over 1211 and 1212.

Any help is appreciated on all of the above codes.

Thanks!

 

P1212 - Injector Control Pressure Not Detected During Crank.
P1211- Injector Control Pressure Sensor Above / Below Desired

Mine was throwing these kind of codes and wouldn't start. It was a bad battery cable. It would give enough power to turn the starter, but not have enough for the computer. I put new ends on them and cleaned everything up. Hasn't missed since.

 

Okay, I found what the last two are..

P1211 ICP Not Controllable - Pressure Abow/Below Desired
P1212 ICP Voltage Not at Expected Level

Can somebody elaborate for me on these codes. This is my first diesel so any help is very much appreciated. Can I still run my truck with the above problem but yet get it fixed in the near future?

 

P1212 is why your truck isn't starting. Either a bad ICP sensor or a bad IPR.

Next time your truck doesn't start, unplug the wiring harness to the ICP sensor (sits on the driver's side oil rail behind the alternator). If it starts, the ICP sensor is at fault and needs to be replaced. If it still won't start with the ICP unplugged, then it's a sticking IPR and needs to be cleaned or replaced.

 

When yours was throwing these codes, yours flat out didn't start or sometimes would and other not? So far I drove, started and stopped my truck several times today all with the key.. no issues so far.

 

Curtis, I found where the ICP sensor is. Will the ICP sensor ever cause the truck to shut down at any given point.. or is it mainly on start up?

Also, what are the other codes for,, mainly the exhaust backpressure one?

The glow plug indicator light.. is that the "wait to start" light? If so, I never seen that light in the instrument cluster. I only seen this wavy light in the upper left corner which I figured was for the glow plugs?

Thanks again for the help so far!

 

Mine would start fine and hickup. A couple of times it wouldn't start. I would pull the battery cable and clean it and it would start and run fine. The cable at the first battery was bad. Ford wants $90 for a new one. I put heavy duty eyes on each cable (3). I then put a heavy duty marine style terminal on my battery and tightened it down with a big nut (not wing nut). It works great.

 

BTW, mine would crank fine but not start. I was just not getting enough juice.

 

look here for detailed instructions on cleaning the EBP tube and sensor http://guzzle.rbmicro.com/ebps.html

The little squiggley light that you are seeing(or not seeing) is your wait to start light, or glow plug indicator light. you may want to check your fuse block, and also check your Glow Plug relay. look here http://guzzle.rbmicro.com/s_gpr.html

P.S. Welcome to FTE

 

Thank you for the above links. I can see the squiggley light in the display so I assume its working. The previous owner just recently replaced all the glow plugs and glow plug relay about 3k ago. I'm assuming the code was from awhile ago as everything appears to be work properly there.

Can the EBP tube effect your performance and mpg drastically? Like I said, sorry for all the questions, I am learning as I go. I think I read my service manual about 3 times..lol

Thanks for the welcome. I actually have been a member for quite sometime now but usually just read a ton. This site really has helped me with my previous vehicles in the past! Thanks!!!

 

It can be both. By unplugging the ICP sensor from the harness, the PCM will load "default" values for the ICP table and allow the engine to run. That's why it's important to try that test to see if it's the ICP sensor that is faulty or the IPR.

Probably not drastically. According to Ford the EBP sensor has nothing to do with fuel tables and only has its purpose regarding the EBPV. However, that being said some have mentioned that the EBP sensor readings are included in fuel mapping. How much? Who knows. Personally I think it has more of an effect if you throw a code for high backpressure, since the PCM in some cases can defuel a bit. But anywhere up to that point probably has very little to do with fueling and overall mileage. Keeping it clean will ensure that your EPBV works properly.
