Oil pressure switch/no start - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ok, last night I took the distributor out to replace the oil pressure switch
Turned the engine over by hand 3 times (just to be sure) until I felt compression.
Reconnected everything and no start, have a orange wire from the fuel pump relay to the battery and the fuel pump runs but still no start.
I tried a paperclip in the oil pressure switch connection for the fuel pump and again I hear the fuel pump kick on but no start. Engine turns over strong.

Any advice/experience is greatly appreciated. Thanks.

is there any way to bypass something to make it run?
