Engine cranks but wont start. I checked fuel pump relay it tests good. Have twelve volts at fuel pump relay. Relay activates with ignition switch. But I get no voltage to fuel pump.
I also checked spark to plug number one and I get spark.
The fuel pump was bad and I changed it. I also tried a new fuel pump relay to no avail.

any suggestions?

If the relay works and no power to pump it is either a contact problem or wiring is broken someplace so check for that. if relay is not sending power then try resetting security sytem. See link.

Thanks I found the location of the problem. The jack that plugs into the fuel pump assembly has either a broken wire or is just not making good contact.
