Re: vehicle problems

Do you have a shop manual with the ecm pinouts? You need to check the ingnition and bat wires and make sure the computer has power on all circuits. Also, make sure ALL the grounds are connected and secured.

are the three plugs under the pass kick panel pluged in??? They are blue, white, and black in color. These three plugs will make these not work, starter, alt, and no PCM sync. I would start here and get back and let us know.

Re: vehicle problems

yes the wire harness was completely out...i stuck the harness through the firewall and connected the 4 connectors that came through...i guess if some can go to shoebox site i could see if the pcm is gettin voltage... i think the fuel pump isnt commming on either...its as if the acc switch isnt working...bc it turns nothing on...
