need some help guys, i just finished up changing my heads, went to start the truck and it turns over but but wont start. ive checked everything that i disconnected atleast 10 times, any ideas.

btw, i installed stock heads

 

sure you got the grounds all connected?

 

do the checks does it get fuel, power to spark, grounds and so on can be sumtn simple

 

i only remember disconnecting one ground, the one on the alternator.im getting no codes, but im not sure if im getting no fuel or no spark.

 

if its turning the motor over but not starting i would start with the fuel just pull the number one plug out and put the end on the threads of the sprk plug hole and have someone start the truck for a second or two and can tell if your getn spark and fuel

 

See if you can spray starter fluid down the open throttle body while cranking (not the MAF), if it fires up but dies that will eliminate the fuel vs spark issue.

 

Thanks for all the info guys, but I think i know what the problem is. I will check this afternoon when I get home from work. I will let u know what i find.

 

There is a ground on the back of the motor, you shouldn't have to disconnect it to r&r the heads, but if you did that could be your crank no start issue. Like everyone else said i would def. check fuel pressure, spark tester is always a good cheap tool to have.

 

got her running guys, thanks for all the helpful info.

 

What was it?
