CRM1988 Posted September 20, 2010 Share Posted September 20, 2010 ballast resistor heating up any ideas as of why? Link to comment Share on other sites More sharing options...
HOrnbrod Posted September 21, 2010 Share Posted September 21, 2010 The ballast resistor is a high-watt low-ohm power resistor that drops voltage to the fuel pump so it will run quieter and last longer. It's supposed to get hot, real hot. That's why they are mounted in a porcelain housing. Link to comment Share on other sites More sharing options...
CRM1988 Posted September 21, 2010 Author Share Posted September 21, 2010 But that's the problem i am having the truck act's like it is running out of gas and when i shut the hood it completely dies.I have pulled the fuel pump and it is good and replaced the filter.I replaced the old ballast resistor cause it was cracked and the guy at autozone said the truck didn't call for one so he picked one off the shelf that looked like the old one.don't think that it was for a jeep.If it was the wrong one could this be causing my problem?

mvusse Posted September 21, 2010 Share Posted September 21, 2010 Just bypass the resistor. It is there because the pumps are a bit loud even when working properly, and is bypassed on start up and during WOT. The 87s never had one. Link to comment Share on other sites More sharing options...
CRM1988 Posted September 21, 2010 Author Share Posted September 21, 2010 So it will not hurt anything to hook the wires together and throw the resistor away? Link to comment Share on other sites More sharing options...
Geonovast Posted September 21, 2010 Share Posted September 21, 2010 It might slightly reduce the life of the pump, but you should be fine. Only other side effect is the noise, but chances are your truck makes plenty of other noises to cover it up. Link to comment Share on other sites More sharing options...

Geonovast Posted September 22, 2010 Share Posted September 22, 2010 Check your fuel pressure. Link to comment Share on other sites More sharing options...
