so i built my motor, first time i cranked it, it started right up had no problems, the 3 time i tryed to start it i will crank but not start. If it does start when the motor is warm it will start every single time.

it is not the fuel pump , or the fuel pump relay..

any idea's, would make the start up richer help? or does it sound like somthing isnt working right

UPDATE TO PROBLEM: It was that the Cam angle sensor had Oil on it, cleaned it off and now it is prefect

 

do you have spark? check Crank sensor

 

Check the plugs, check the gap on the plugs, make sure you have adequate fuel and fuel pressure, and check compression.

 

i was thinking cam angle sensor

 

anyone?
