Hi Im David, dont worry, this is not a ripoff sight and you will only be charged what you initially offered. first of all these problems all started after you did the above mentioned work, correct?

Expert:  david craig replied 1 year ago.

it honestly sounds like you forgot a connector or 2...double check all the connections on the engine. front,rear,sides.... triple check then
