Fuel Pump Electrical Issues
My 97 XJ's fuel pump isn't kicking on when you turn the key. There's low volts (~4) to the Fuel pump relay, but when you bypass the relayand jumper the pump it primes and the Jeep starts. Any idea what could be causing the voltage drop?

We later figured out that it has no spark either, and isn't throwing a code, so we thin kit's the computer. I can't do anymore with it now since we're in Florida for the Holiday.
