silverado icm high voltage
 

I have a 2000 Silverado Ithas the 4.3l v6 1500 4x4 I have put over $2k in new parts in it sensors etc. it will turn over and act like it is going to start then nothing .sometimes it wll start and run\drive the only trouble code that comes up is p1351 witch is high voltage to the icm .

I have know idea what to do I have checked grounds looked for bad wires but haven't found anything ....

any ideas ??

the exact same problem just fixed it today my truck is running once again one of the first things that I change was my ignition coil camshaft sensor and ignition module,.problem was the ignition coil !!!!!change that one more time.

I got mine running again to and didn't do anything to it. It just started and I thought the problem may have to key switch so I changed that and it has been starting ever sense but in the morning when you first drive it it runs like crap untill it warms up then it runs great
