Help needed Please, installed my rebuilt motor and it wont start
 

I have intalled my new engine (Rebuilt 3.0L) , and I'm trying to get it to start. I do have spark and I have fuel. When I lift up on the sensor plate for a few seconds and then try to start it , it will turn over, fire up for a few (3,5) seconds and then die. I continued to do this until the battery died. I'm going to recharge it over night and try again tommorow.

What is my problem? Why wont it stay running?


Thanks for any input

did you attach the brake booster hose? big air leaks cause what you describe.

Agreed - check all your hoses. Check the vacuum pull when the engine is cranking over too (if you have a vacuum gauge)...
