I drove into a water hole and water came into the floor boards ever since it has rained real bad. I replaced the fuel pump and the alternator and it do not run at all. There does not seem to be any power to the fuse running the fuel pump. What do I need to do? Thank you.

Hello,

There is a ECM replay that could be causing the problems. Here is some wiring diagrams and a guide so you can check the relay and some power inputs to the system.

I got 2 very good responses to my question a few days ago concerning the Injector Wiring. Now that I have them connected can you email me a diagram detailing ALL THE CONNECTIONS that remain on the harness? Also where do I attach the ground lug? Does it connect along with the strain relief clamp at the front of the Intake manifold? Thanks again for all the good help you provide.

I am providing you with a diagram of the manifold and fuel rail. I did not know if you have the 2.6 or 2.8L, so I provided you with both wiring diagram that are mraked by color codes for wires which can be used to identify connectors.
I had to split the diagrams into 2 part, top and bottom, sets because they are illegible otherwise.

Let me know if you need any more help with this issue.
