Bypassing Oil Pressure sensor

Not only have I done that, I pulled the wire harness and the motor and installed everything that originally came together (motor and harness from a 1990 Chevy 1500).

I am obviuosly very close as I have been driving it and everything runs great... except the now 2 issues I can't seem to figure out where I went wrong with. Just got off the FAQ again looking at all the diagrams for the fuel pump relay. Still don't know what to do to get pump to turn off after 2 seconds of not running in the on position.

So...if you read the FAQ's over and over....did you actually verify them with your system or did you just ASSUME you had everything "perfect"?

The definition of insanity is doing the same thing over and over while expecting a different outcome.
If you didn't physically check each wire then you didn't follow the FAQ's.

seems you didn't need me at all and just had to convince yourself that maybe there was a problem with the wiring.

But if you do need me...you know where i am.

You are right Bill, i guess i had to convince myself that all was not perfect but sitting in front of the computer eventually got me there!
Scorp1us... In answer to your question regarding the oil sender, at first I had thought this was part of my problem since I had failed to disconnect it at first. Also, through some reading it had looked to me as if I was supposed to ut and then permanently bridge the sensor's two wires together. That was obviously not the case since the orange wire is from the Battery and that would have set the pump into permanent run mode.
So, today I'm heading out to discover why the pump does not come on right away when turning the key to engage the starter. It didn't seem to last night so the engine spins far more than 3 times before starting. Right now I'm thinking of attaching the pink/black wire (that used to go to the oil sender) to the small terminal on the starter... But we will see. Perhaps I need to read the FAQs for the 98th time

No, this is not how the wiring diagram is.

So am I ... as a matter of fact... turns out I just discovered it isn't! wow... my head is very thick.

It is officially gone.

Still a problem though... the motor will not start when cranking. I found the Green/White A1 feeds juice when the key is turned to "on" for 2 seconds then turns off. When I turn the key to start, I am not getting any juice from A1 and C9 IS hooked up correctly so it IS telling the computer the engine is being cranked.

Does A1 NOT feed juice to the fuel pump relay until after the engine starts (normally in 2 - 3 reveloutions)? If this is the case and my electrical system is functioning properly, must I be lacking fuel in the fuel line as if it doesn't hold pressure?

"Deserves"... I'm not sure what you mean.

Bill, I realize that it is not in the wiring diagram to hook up the pink/black (that used to go to the sender) to the ignition start wire. However, until I figure out why the line is not holding gas between start-ups... I was going to do this as a kinda "by-pass".

You really need to just stop for a minute and stop thinking cause you are leading yourself down the wrong path.
Go back to my first post in this thread and slowly read when and how the fuel pump turns on....without assuming you already know.

C9 isn't even needed and has nothing to do with the fuel pump.
Sounds like you are going to other sites and listening to others.

That's from my signature, has nothing to do with you. Just click the link and read the wiring diagram.

[meyeda]

I'm trying NOT to think (a catch 22) and am really looking at the diagrams.

I've found my pink/black source wire to the ECM and the White and Red wires to the injectors are hooked up so that they are 12V ONLY when my key is in the On/Run position. They are NOT receiving juice in the Start/Crank position.

Then you are not using the original coil + scout wire to energize the relays as discussed....hmm where was that.......oh yah the FAQ's.

Or you not powering them from the relays at all.
