DP Tuner and a burnt out fuel heater??????

[mako314]

I have a DP tuner and about two days ago the fuel heater in the filter houseing died and blowed some fuses, well anyway the chip was removed thinking that it was the reason for the no start and then I found the blown pcm fuses. after finding and fixing that the truck started no problem. I reinstalled the chip and the truck would not start. would the heater going out cause the chip to erase or something or do I have some other problem? sorry so long and thanks for any advise you guys may have.

It sounds like the contacts on the PCM are not clean enough. Take out the PCM and clean the contacts again and try that. If it still will not start, call Jody.

I have never herd of a chip having anything to do with the heater unless it has to do with a bad contact.

Again, start over and clean the contacts real good.

try checking the fuses again. you might have a short in the fuel filter area with your fuel heater. this happened to me the other day and i was poppin fuses as fast as i put them in. you need to disconnect the fuel heater wire. just take out your fuel filter, and there is a red connector near the bottom of the fuel filter. just use a pair of needle nose pliers and pop it off. it's easy. you dont really need the fuel heater.

+1 for checkin the pcm connections... any dirt or obstruction will mess it up

I got the problem narrowed down to the chip. talk about customer service, Jody at Dp Tuner is sending me a new chip. I had the fuel bowl heater fixed before I retried the chip.

Jody is a good man, he will get you roll'in again. Let us know what it ends up being. I too think the PCM connection, can't see how the FH could fry a chip, but the new chip will prove if I am right or wrong. Have you tried hitting the contacts with some scotch brite pads?

yeah I tried all that jazz, I went through the whole install again and still nothing. I ran the chip for 8 months with no issues so the connection was good, I thought..
