2003 Ford excursion 7.3L powerstroke eddie bauer edition, vehicle wont start unless the block heater has been plugged in and the block is good and hot. This is its only symptom. It is throwing the following codes when i try to start it. Mind you it is 70 degrees so it shouldnt have to be plugged in to start
P0470 : Exhaust Pressure Sensor. P1000 : OBD System readiness test not complete
When the block is cold my truck will not start. If i keep the block heater plugged in it will crank but is still a long start. I have tried just about everything i can think of and it is way too much to list so i will give as much info as i can.
New- gpr, glow plugs, HPOP, batteries, starter, fuses, valve cover harness/ injector and glow plug wiring, vacuum lines. I have checked out just about everything remotely possible.
Ok, is it possible to blow a fuze if the block heater is still plugged in when starting? Almost did this the other day and wondered if its possible to cause a short or something.
View 6 RepliesI can't get my truck to start. The block heater isn't working and I previously put flush and water in it, intending to drive it and flush it directly after. Well I never really could drive it and now it won't start again. The weather is going to turn off cold, around zero this weekend. I need to know how to keep the block from freezing and cracking!
View 11 RepliesDon't drive the truck but once a week but since its gotten colder here than usual is been harder to start when cold. Of-course I go thru the glow plug wait and then it kinda stumbles when its about to start. I do it again and most of the time is starts but seems rough for a few seconds. Once the truck is warm, no more problems starting.
I'm wondering if I have a glow plug gone bad and that cylinder is not warming up for me. Today I plugged in the block heater for maybe 2 hours and it started first time. Also, if just leave the block heater plugged in for long periods of time.. would it get to hot?? and wonder how expensive that is, most heater are costly to run. I have a timer but just wondering.
I don't think that my block heater is working correctly if not at all.
View 14 Replies I wanted to specifically ask about the block heater though. Since I bought this truck I never was able to start the truck without plugging it in. Now that it's not running I'm thinking much more about the block heater.
Is 56 too low for this old truck to start? What temp should a block heater have the oil temp as seen by AE be?
I live in the southwest so it's not very cold here. plugging in the heater was even required in the summer unless the truck had been running. What kinds of engine trouble would require being plugged in in warm conditions?
Doing oil cooler. Block heater plug is very tight. Is it reversed threaten?
View 1 RepliesCold no start goes nowhere. I have a 2001 7.3 that will not start in the cold if I forget to plug it in....like last night. I have to plug in the block hater and give it a while before it will start. I tested the glow plug relay,it works fine. I can not find a test for the fuel bowl hear, and I'm not one to throw parts until I accidentally fix it. Any test procedure for the fuel bowl heater? Why this POS is so bad in the cold? Glow plugs tested fine at diesel shop in December, and this problem has been around since before that.
View 14 RepliesMy 2001 7.3L Diesel has 222,000 miles on it. Yesterday I shut it off at a drive through window, went to start it and it just cranked, no start. The engine light and the wait to start light did not come on. I plugged in a code reader this morning and when I turned the key I heard a buzz and a click, I noticed the engine light and the wait to start light came on. I cranked it over and it started right up, when I unplugged the code reader, it died. Plug it back in and it runs, dies every time I unplug it.
View 13 RepliesI purchased a 2002 Dakota and have had a hard time ridding it. I thought that the heater core was leaking and getting the passenger side floor wet, but it's the overflow for the evaporator under the dash. The drain must be plugged. Will I have to remove the dash to pull the heater unit down far enough to clean it. I don't think I can do much from under the hood...too tight.
View 4 RepliesI have a 2011 F-150 with a 5.0 V8 and am in need of a block heater. Who makes an aftermarket heater that can be installed in this truck. I expect to see lows as low as -50.
View 4 RepliesI didn't have time to trouble shoot but heres my problem. I plugged my 2016 6.7L in last night and when I checked it this morning the block was still ice cold. I didn't have time to investigate but i did make sure i had power up to the truck. And i noticed there's a connector just after the truck plug as well.
View 14 RepliesDoes the block heater come with some kind of a cord? I found the Box Link stuff under the back seat finally, the dealer said the block heater should be under there too? But it aint there?
View 6 RepliesWhen I bought my truck it didn't have the block heater installed, asked the dealership to put it on with the deal, but they didn't have one there. How hard it is to install one? Also what brand should I go with? (On my '16)
View 5 RepliesWell, I swapped a 2011 F250 SC for an F350 CC and I really enjoy driving it. 300 miles on the clock. My old 250 had the block heater and the pigtail to plug it in was low in front of the radiator. This truck also has the block heater, but I cannot find the pigtail to plug it in. In 2016 where Ford hid it at?
View 14 RepliesWhat the coolant temp should be around after plugging in the block heater overnight? Not looking for an exact measurement since this can be affected by OAT and the length of time it has been plugged in. But when it's -15 to -20F this weekend I was wondering what to expect.
View 13 RepliesIt got down to the low teens the other day and I thought I would use my engine block heater to see how well it works. But when I got in the oil temp was basically the same as the air temp (it may have been 5-10 degrees warmer but still not above 20*F) after being plugged in for 2-3 hours. Is something wrong here? I would have thought it would have warmed it up or does it not affect the oil temp? If not, what does it warm up?
View 7 RepliesI am trying to find out how many o2 sensors are suppose to be on my 2003 excursion? I am getting two codes on my OBD reader, an "o2" and an "o2 heater" code flashing...... I have replaced both the o2 sensors i found, both were at the exhaust manifolds.
