hi guys i pulled off the winter cover and tried starting the engines its a 2000 with 500 efi's one motor only will fire on one bank nothing on other side and other motor has 2 psi fuel pressure i replaced both fuel pumps last year so thinking its a regalator issue on the one engine but the other will only kick on one side thinking there may be a bad ground issue on the injectors ? i am going to order a scanner this week since kinda lost with out it any help would be great thanks off shore only

Grounds are a good place to start, especially the one/ones that ground the ECM itself.

Ya I am hoping that's all it is I need to look in the wiring diagrams see if there different sides for injectors

Check your batteries! I had issue last spring, radio came on, though I didn't crank it up. Motor wouldn't do anything, ended up being dead cell. It was weird b/c it had a lil juice to run radio and other accessories I tried as I was trouble shooting.

Cold can kill batteries!! Good luck ,
