Bad Pcm?
Well i had posted that my truck was starting hard.I thought it was maybe my glow plugs.I took it to a really good dealership near me.I personally know the tech.They called me and said the glow plugs are o.k but that my pcm was bad.They said it is not communicating with my glow plugs.I do have a 3 stage dp tuner.It has been installed for about a year.They said they do not think it could have caused it but they will not hook it back up.They are special ordering a new one.They are chargeing me 800.00 bucks installed after tax.Does this sound right and am i getting boned.I could really use some help.

Tuners can and do go bad. I know this from personal experience. I'd ask them to flash the PCM back to stock and see if it runs before I would cough up 800 clams for those thieves. Then if it is the tuner, go from there. That is what I had to do under the same circumstances.

I hear what you are saying,but believe it or not they said they dont think it was the tuner.But they said it was 2 hours labor to install a new one.If i remember correctly it takes about ten minutes.

or
just buy a PCM and install yourself.
but
THere is a way to see if the PCM is bad by ohming it. Someone this winter had the glowplug (diode?) go bad in their PCM and diagnosed it this way. THen spen the money on the PCM. I will be searching for it, will post back later.

Problem is they already ordered the new pcm,and they are chargeing me diagnostic time.I will have to eat that ,but i am definitely gonna beat them up on the install.To make it worse i just looked on the dp tuner sight and found them for sale for a little over 300 bucks.this is a tough lesson learned.i should have talked to you guys before making any decisions.
