Hi, I was wandering if anyone has ever replace a glowplug with a resistor or something that tricks the ECM in to thinking that is the glow plug. if so what is it? I was thinking on a ballast resistor but I dont even know how many amps the the glow plugs get when in use. Any ideas?

Ok, according to the service manual a single glow plug would take a max of 8 amps depending on ambient temperature. if I hook a 10 amp ballas resistor will it trick the ECM?

How many Ohms is the ballast resistor? I believe the resistance of the glow plug is about 1.5 Ohm...very low...hence why it draws about 8 amps. It is worth a try to use the ballast resistor if the resistance value is similar to the glow plug, bear in mind that there have been a lot of posts about the wiring harness to the glow plugs sometimes being connected the wrong way around...so be sure you are working with the correct glow plug

cheked the harness and it is ok, I'll swing by ace electronics tomorrow to see if i can fin a chromnickelsteel type of resistor that might emulate the same resistance as the new metal 5v glowplugs.

Hopefully I am understanding you that you're already running the lower voltage gp controller then just install the new metal GP's and there's your needed resistors!
I know the ECU needs a flash too or the newer controller will be incompatible with the computer(?)....
I know GP replacing can be a PITA however.....

all glowplug system has been update to the 5v, including GCU and ECM, I just want to get arround replacing a plug that is stuck on the engine, I dont want to remove the head. 3 plugs will do the job just fine for me.

Has the plug been broken off or just "stuck" If it's just stuck get some good penetrating oil like Kroil and give it a shot every day for a week then gently try loosening it. If not repeat.
