Will the crank position sensor from a 4.8 work on the 5.7???

I have no spark and no injector pulse.

 

we use a pressurized squirt can....some people use standard garden sprayer cans
fill it halfway with oil, pressurize it with air,connect it to the oil galley plug just after the oil pump in the drivers side front of the block, squeeze trigger...it will push oil thru all of the oil passageways and prime everything...some of it will go back into the pump as well and it will be ready to fire up.

 

Well after i connected the wiring harness to the crank sensor, it fired right up. Good solid oil pressure in less than three seconds.

But the front main seal is leaking. Of course that is the only gasket/seal i didnt replace. Laziness never pays.

 

Nice, good to hear. At least it's not the rear main seal leaking!

 

Yeah, don't pack the pump with grease. Use assembly lube or oil. I prefer assembly lube since it is tacky and will stick to the gears, which is crucial if you wind up storing the motor for a while before firing it up.

In a pinch, you can also use vaseline. You essentially want something that will lubricate all friction points and then burns away once oil has taken over the job. Using something like white lithium grease is a bad idea because it doesn't burn away and will most likely clog up an oil passage.
