the swap begins

the sending unit on the 98 comes off at least the one i have does lol. if not use a big hammer lol

I think you're right beater6.0, a lower resistor might work.

If you add any resistors inline to the 98 sender its just going to make the situation worse. Replacing the resistor is your only option if you don't have the original PCM handy.

Try grafting on an old sending unit to the new unit. You would have to add the resistor across the sending unit, not inline to lower the resistance.

Greg, I meant to change the signal from the PCM using a variable resistor of some sort. My neighbor did his and he said it works but I'll need to get the information from him to see exactly what he did. The only resistor I know of is the variable on the unit itself because there's nothing else except for the pcm in between. I know changing the sending unit would be the best option but if we can find out what the PCM conversion signal is we might be able to add something up by the cluster to mock the pcm. I won't give up on this one just yet.

lol please dont! i dont have a fuel pump at the moment. for a 96-97 lol and dont really feel like buying one haha. keep me posted with what you find. its the only thing not really working yet... speedo and tach work so thats good.
