93 chev 6.5 fuel problems
I bought a '93 6.5 5 speed a couple of months ago it ran great at first then it fell on it's face, started blowing white smoke ( unspent fuel) hard starting and overheating fuel pumps. I've replaced the fuel pump, injection pump, and the oil pressure switch now I have a bunch of new parts with the same problem, please help thanks

Does the waste gate move freely while not running should be able to move by hand??
|
Yes it does with the pressure of the spring
|
can you do a compression test and post results?
|
The white smoke could be head gasket issues a well
|
White smoke smells like fuel, if it was a head gasket what would explain the overheating fuel pumps
|
By fuel pump are you meaning lift pump or injection pump or both ????????????????
|
The lift pump on the frame rail
|
The LP overheating issue could be one of 2 things wrong with it 1st ic could be that the fuel sock in the tank is clogged or caked up with debris or you are experencing an electrical issue of some sorts,the white smoke means you are not burning all the fuel entering the cumbustion chamber-chambers either bad piston ring or rings or a cracked I would do is a cmpresion test make sure all cylinders are within plus or minus 10%
