Thanks now im getting some ideas. im gonna sk some of the mechanics here at work, and maybe visit a few junk yards see whats out there, maybe just try what Jr. suggested just for ****s and giggles! but seeing as how the computer is fried, and there is no wiring, i gotta figure that part out first.
i should be able to pull the motor this weekend, we'll see.
i wanna get that book "big block numbers from small block mopars" (or something like that)does anyone know if it covers such subjects as this?

Lets look at this as simple as possible. What would happen, if, he decided to put a carb intake on, carb, and put a regulator on the stock fuel pump? (and un plug the injectors of course) I know it would set off a crap load of codes, but I am curious if it would run or the ASD relay would kill the spark.
I really dont think there would be any way of setting timing. I think without the injectors plugged in the computer isnt able to compute timing properly. I dont KNOW, but that would be a concern of mine. It all hinges on what the computer can handle. If converting to a carb makes the computer lame and it refuses to function properly youll have to start looking at all the other things weve discussed.
14 ohm resistors either spliced in at the box, or plugged into the end of the inj. plug would probably fool the pcm as far as injectorsare concerned. I think you might be able to get the ignition to work. Timing is set based on rpms,tps, iat, ect, and the load calc's that the pcm does based on those and the speed sensor. If you left all of those intact, and rigged up something for the tpsyou'd probably be alright.One issue- I'm sure you would tuneat or slightly above 12.8:1. When the o2 sensor sends that info at cruise (based on tps) it's going to start trying to adjust not only fuel, but timing. The pcm looks for .45v from the o2, which indicates a a/f ratioof 14.7:1. Richer sends a higher voltage, so you would need to take a reading on the voltage output at whatever you tune to and figure what size resistor woul be needed to drop the extra voltage. Better yet, maybe a potentiometer with a scanner in the cab so you could adjust as neccessary.
The pcm does not monitor fuel pressure so your good there. Jr. brings up a good point. Why not bypass the regulator on the stock pump, install an inline regulator,andrun a return line back down to the tank. I guess you would have to figure out the duty rating on the stocker. It may work.
Keep in mind, this wouldn't be something to depend on as a dd. lol

dont mean to steal the thread, mopower, do you know where I can get an inline adjustable regulator that snaps btwn the fuel line and the fuel rail? Iv been looking for something for a while but cant find anyone that makes one. Im about to go get a mallory universal one if I cant find anything.
