I do know that my glow plug reay is bad, while I was looing around for a replacement one I stumbled across this guy on Ebay that is selling a manual relay setup that bypasses the timer in the ECU and allows the driver to choose how long the glow plugs are charged. Here is a link
eBay Motors: Ford diesel glow plug Manual relay controller- solenoid (item 280148765762 end time Sep-10-07 16:17:32 PDT)
Any opinion as to whether this is any good or should I just replace the relay with a stock one?
Also, if I do have ay bad glow plugs what is the best replacement ones, Ford or is there some aftermarket ones that are better? In the past I have always had good luck with factory parts.
Thx for the Help
