99 F350 Starting Problems
 

I finally bought a 99 F350 4x4 regular cab with the Powerstroke and 6-speed manual tranny. This thing does not want to start when it is below 60 outside! The dealer had all new glow plugs and glow plug relay installed to fix the problem, but it still doesn't want to start. Yesterday, after I had driven it for a while, I parked it in the sun (it was 64 yesterday) and it still did not want to start after sitting like that for about 4 hours. Any suggestions? Also, the "Service Engine Soon" like come on when you press the go pedal, normally right before the turbo start to wind up; anyone have this problem before?

I have about the same problem with mine... Still can't find the problem.
What I took as a temporary solution is to plug the Block Heater for a couple of hours.

Please keep me posted if you find anything!

P.S. I also had my glow plug & relay check by Ford..

I had a similar problem with my 99 6 speed except for the service engine light, and after a new glow plug relay and cleaning the battery terminals really well, she fires right up.

Check both batteries... if they are low on charge the truck will turn over but won't want to start... My 97 had one battery that was undercharged...same problem that you are having now. Good luck!

ditto on the battery condition...they have to be in very good shape. seperate them and load test them. also, have you change your fuel filter lately ? this would be a good place to start, concerning your ses light coming on.

I appreciate all the help; I am going to try to replace my fuel filter and test both batteries this weekend. I am new to the Powerstroke so I have been doing all the research I can.

If you can start your truck w/ a jump when it acts up, should tell you that you have a problem w/ your batteries.

Use some Diesel Kleen in the fuel filter bowl when you change it.

I replaced the fuel filter, removed both batteries and had them tested, replaced the air filter assembly with a K&N FIPK, and it still does not want to start. And, the "Service Engine Soon" light still comes on when you depress the accelerator right before the turbo spools up. And when you are in 5th gear and doing about 40-45 and you let off the accelerator, you can hear a thumping noise; it goes away when you depress the accelerator again. On top of all that, it is a dog until you get up to around 2K rpm and the turbo really kicks in. The cat has been removed, so it is not blocked there. Any suggestions?

Did you pull the codes yet? That should point you in right direction.

Can you tell me how to do that? I know how to pull codes on a Chevy but I have never done it on a Ford, and never on anything OBD-II, only pre-96 OBD-I.

I read them with my Tuner (Superchips 1705) If you don't have a tuner you'll need a code reader. Here's a starting place.

Thanks, I will check that out. One thing that I failed to mention was that it will start right up if you have the heater plugged in for a while.
