1989 renix starts but dies

A friend of mine has an 89 that's having a wierd problem.

It will start but will only run with they key in the start position. If you let the key back to ignition it dies.

New ignition switch
Good battery
Tried bypassing the Balast resistor just to see if it made a difference. It did not. Any ideas?

Thanks

Fuel pump relay is a possibility as is the ignition switch.

Well as soon as I posted this I figured it out. He told me had swapped the relays around but he lied. I swapped the front two relays and it fired right up second relay back was bad.

Re: 1989 renix starts but dies

I gotta tell y'all, this post saved my butt! For a week I've been trying to fix my kid's 89 xj with the very same problem. Changed ignition switch, checked ceramic balast resistor ... read a TON of discussions. Then I tried switching the fuel pump relay with the one next to it - FIRED RIGHT UP AND KEPT RUNNING!!! Confirms that I ain't no mechanic, but I sure do appreciate those of you who share your experience (BlueCuda, Crusier54). Thanks so much - and here we are 10 years after the original post!!
