I have a 02 7.3 with almost the same problem, I have parked the truck for 2 years due to the economy and this problem. I would like to get it back on the road. My problem is when the outside temperature gets below 40* and I don’t plug the truck in it is very hard to start. Once is dose start I let it warm-up for 10 min and then start down the road. It will make it 1/4 mile and die. I can cycle the glow plugs twice then crank it in 30 sec. intervals for 4-5 times and it will then start, I then have to hold the accelerator to the floor until the white smoke stops coming from the exhaust. While holding the accelerator down the rpm don’t increase above 1200. Once I go thru this each morning the truck runs fine the rest of the day. If the block heater has been plug in it will start and run fine all day.
The truck has 130,000 miles; it is stock, the oil has been changed at 4000 to 5000 miles intervals since the truck was new. Fuel and air filters at 15000. 2 years before parking it and while on vacation the side of the oil filter split and I had it towed to ford they replaced the filter and the HPOP (I don’t know why the hpop was replaced or how it would have anything to do with the filter splitting) In the month just before parking it I had the codes read it showed low voltage to the injectors, I had the cps replaced twice and the fuel, oil and air filters changed. The mechanic told me that there had to be a bad injector but he would have to change them all at the same time. And if that didn’t work I would then need a HPOP. Not wanting to just through $$$ and parts at it, I parked it.
I am sorry for the long explanation but I would like to get this back on the roar and wanted to try to get most of the info in this post. I have rebuilt small block gassers before i can use a wrench and a volt meter but have never got that involved in diesel motors before. If I can find the info I would like to find out what is wrong with this truck and try to get it repaired. Thanks in advance for any info you can give me.
