mine cycles 3 times whenever you turn on the key now if you leave key on. works great just not sure if it hurts anything when glow plugs cycle on a warm running engine. Was told by local diesel gurue that reason it has to cycle when hot to start again is because of low compression. I find that hard to believe on a 35K mile truck, but then again it may have thousands of hours of idle time being from air force
sounds to me like its the glow plug controller and ive had nothing but problems with them..
mine did the same as you are sayin,, so went and bought a new one,, high dollar item too,, hooked it up,, thought everything was all good,, for about a month,, then the glow plug would light up while driving it!! burnt um all up...
then it wouldnt start cold for nothing less than a lil ether,,NOT GOOD..
so i got all new glow plugs and tryed to replace them,, but they had swollen up and couldnt get um out of the heads..
so,, i had to pull the injectors out and bust off the un-screew end of the glow plugs and fish out the rest of the glowplug end out though the injector hole,,X8!!
what a bitch that was,, so i just hooked up a button like was mentioned above and its worked great ever since and ive got 8 years out this set of GP'S.........
At first i was wondering if ya were talkin about the censer @ the back of the head on the pass side....... thats the pump advance censer for when its cold,, those give up the ghost also and stick on and the motor wont run right when it does, the motor will be to far advanced and run like ****, i also hooked that up to a toggle switch and hardly ever need to use it...
