So are you talking that it will turn over but it will not start? The starter is cranking but the motor not running?
Yeah, it would crank but wont start
Sounds like pick up coil was starting to go bad the few times you did get it to run. And now it's completely done.
The 4.3L engine is notorious for fuel pressure issues. First thing to check would be the fuel pressure. It should be 56 to 63 lbs. Watch the pressure gauge for 3 minutes after it builds up pressure with the engine off, pressure should not drop more than 5 lbs. If this is the case, you should dead head pressure check only checking the fuel pump to verify the problem does not lie there. Otherwise the problem would be in leaky injectors, leaky spider lines, and fuel regulator. It would be recommended to replace these items as a new unit, as it has ben redesigned.
Thanks Rowefast im going to give it a check hopefully this may be the problem
