Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

Expert:  rpmdiag replied 9 months ago.

Seeing that you do have a signal but it's weak, this would be a ground issue. First check that all computer grounds are good and if they are, then the computer is bad.

Thanks, Ron

ok so what wires are the ground wires to ck please

Expert:  rpmdiag replied 9 months ago.

Start with the battery negative leads to the computer, then check the ground coming off the computer to the chassis.

Thanks again and please remember to rate me 5 stars and keep this link in case you need me again later on.

You can blow out th computer testing injectors with a test light, you MUST use a NOID light.

You probably blew the computer now.
