ECM STOPED FUNCTIONING

check fuse relay wiring and switch and if lighter kept blowing fix dont throw in bigger as you see could have burnt truck down

A BAD TRANSMISSION NEUTRAL SAFETY SWITCH OR FAULTY PCM WILL BLOW THE IGNITION FUSE.

time to change the alt be for you computer gets a good surge and then you will have big problem's hope this helps good luck bob

Sorry i can't tell you how on that viechel but you need to reset your ecm 'Computer" good luck.

a fuse only blows when it is overloaded eg.if you have a 10 amp fuse & the unit it supplying power to is drawing 15 amps it will blow, that is why the fuses are there,firstly make sure you have the right amperage fuse,if it keeps blowing,whatever it is supplying power to is faulty, don't try and overcome the problem by using a bigger fuse as you may start a fire......hope this helps.....cheers

Check the fuses, I had one a while ago that kept blowing one of the ECM fuses. There are 2 ECM fuses one also sends power to the fuel pump too. Do you hear the fuel pump run when you turn the ignition switch to on? Just turn the key to the "on" position, not all the way to start, you should be able to hear the fuel pump run for about 3-5 seconds. I think it takes a 15 amp, I showed the owner which fuse it was and it would blow occasionally. One day it blew one right after another so he put a 30 amp in, he was out of 15's. I told him that was not a good idea. Anyway, that fixed it he drove it home and put a 15 amp fuse back in it, it's been good ever since.

I'd try a 20 amp maybee even a 25

sounds like you need a new ignition switch the pass lock is screwing up common.

try looking inside distributor
