fuel issue?

ok i bought this truck it had a blown head gasket... i rebuilt the top end and timed it. it wont start on its own. but when u pull start it it fires up has no power and puts out this white/grey smoke. when it fires up it will run for about 10 sec even if you hold it to the floor. then it dies.... but you can let the clutch right back out and it will start again... bad incjectors?? it did the same thing before i rebuild the top end...

sounds like the problem I had......could be 180 degrees out of time. I had that happen and it would start after lots of cranking and then it would have no power and just dump grey smoke!

well i cant say its exactly on time since i didnt remove the front cover but i can.... but why would it act the same way it did before the rebuild? i had to replace the valves too lots of coolant build up on them.... and when i pulled one of the injectors out it had new rust on it...
