Hello,

Got a 1995 K1500 4WD with a 5.7L. Just changed the intake manifold and put on a new Holley throttle body. Went to start it and nothing, Because we pulled the distributor, we reset the timing (many times over). Ensured the timing and firing order was correct. Still nothing. Spent two evenings trying to start it, but still nothing. The fuel injectors are dumping plenty of fuel. Just does not want to start. Decided to pull the dipstick and smelled fuel. From all of our attempts to start, the fuel has seemed to dump in the crankcase (or at least we are smelling it on the dipstick - very strong).

So, we re-pulled the intake today and inspected for a crack in the intake or if the new intake gaskets had slipped during install. There seems to be no evidence of either. However, we do not understand why the fuel is in the oil? We are also lost that the engine will not start. It cranks all day long, but no start. We had what seemed like a couple of hits, but no start. We even increased the fuel pressure thinking the new Holley was not dumping enough fuel. Also, after all the attempts to start, we pulled the #1 and #4 plug and they were dry as a bone. The engine just seems to be getting no fuel in the cylinders to fire off. We cannot figure this one out. Any help would greatly appreciated. Thanks.

ok can you see the fuel being sprayed in there when you crank it over? and the fuel your smelling in the oil could be from before you installed the new holley

 

Good point about the fuel being there before. Yes, when cranking the injectors are spraying great and the psi is between 14-15. Thanks.

so if you pull off a spark plug and crank it over and put it next to a screw driver or metal cab you see the spark jump? possible you have the distributer 180 degrees off?
