I blew my head gasket a few monthes back, Got my head and intake ported, Just put it all back together arp studs, cometic head gasket. now my timing is dead on i have fuel also spark, The car is cranking over sounds like it wants to start badly just giving in. I changed my Cam position sensor, Mine was bad caked in oil also got hot very fast. All in all im very stumped.
 
Check your timing marks. Did you install the head your self. If you you did not line up the timing marks correctly it will never start. You can also do a leak down test to see if your valves are seating correctly. Also do a compression test.
 
I forgot to add this we had it running and it stood running but had a bad miss to it, almost like we were off a tooth, I gave one good rev maybe 4.5k - 5k sounded good once it broke lose, but then shut offf and we havent got it to start again. So me and my father took off the cover brought it up to TDC and all marks were lined up still, It did flood my new plug when first trying to start it could it maybe be faulty plugs? Or from the rev maybe a fuse for ecu i havent checked that? But im stumped. Were gonna do a compression test today.
