Start, No throttle Response

[RoGrrr]

Newbie here
I have a 96 7.3 PSD, auto tranny. Edge programmer, 5 inch stacks. Nothing else that would seem to make a difference.

I start the engine and it seems to start normally. Well, almost normally. I think I need at least some new glow plugs. However it takes anywhere from 5 to 15 seconds after it starts before I can get any engine response when I press on the accelerator pedal. Once it starts to respond, it goes like a bat outta h3ll.

Is there anything I'm doing wrong or is there a problem with my pony ?

Possible tps going bad or throttle position sensor. There is no linkage its all fly by wire per say. Its possible that is what your issue is.

some time when it real cold my 97 will do the same thing give her time to warm up to you then go like the bat out of hell 97f350

OK, so where do I find this little aminal ? I understand FBW so is the pickup under the dash ?

BTW, I forgot to say that it's an F250. Not that it makes much diff.

And is there any way to check it out ? I have plenty of electronics test equipment.

Does your edge programmer scan for codes? If it does see if that code comes up. I can't remember what the code is. If you buy it from ford you have to buy the whole foot pedal and its pricey. Let me see if I still have a link for just the sensor.

Here is the link, but the site must be down right now. http://www.dormanproducts.com/docume...s_Sensors2.pdf

Just a guess but it could be something to do with your HEUI fuel system, if for some reason it takes it those few seconds to build full oil pressure, when was the last time you changed oil?
If it was a TPS it seems to me that it would act up other times besides the first 15 sec.
Could be wrong but thats my two bits!

I talked with the local garage guru here (well, THAT's what he calls hizsef)



and he said to CHANGE THE OIL

So I splained that I got this sled fum a fella whoz suppozed to know what's going on and told me that there aint no more than 1500 miles on the oil and it's UP.



NOW GET THIS

He says to dump the oil, filter and put in 14 QUARTS, no matter what the dipstick says.

Startin to sound good now. OK ?

Then he SEZ

Look at the dickstik and if'n the oil level shows LOW

CUT THAT MUCH OFF THE STICK TUBE !




So I ax:

WTF ?!?








He sez that if the oil's low, that the injectors aren't being opened and I need tomake sure they get enough oil



Hmmm


He also said that it normally happens when it's cold or on a cold start. So that's what I've experienced.

But, yeah, I have the link for the DORMAN replacement sensor and I'm keeping that in the back of my mind.

(what little there's of it....)
