I just replaced my injectors because a mechanic told me they were bleeding off the pressure into the cylinders. While I was at it I did the spark plugs and wires. I got it to start and drive around the block once but it was very shaky and had almost no power. Now it won't start at all and after I turn it over I can hear what sounds like air pressure bleading off. What do I do?

 

Might be nice to know just what engine??

Injectors harness not on correct

Wires not on correct

coil wire not seated in the coil fully .

Then it might be unrelated to the work you just did.

 

Sorry, its the 3.0 V6
