New plugs a month ago(we think they were the original ford plugs that we took out). Has only been driven about 125 miles since.
Started running rough shortly after plugs were done and got worse. After about 70 miles were on it the check engine light came on. I drove to my brother place to run a scan, it said a misfire in cylinder 1. He also goat a soft code that said something about continous fuel level, but it wont re read it. He told me to get a new coil. A bit later I got in to drive home and it would not start. Cant hear the fuel pump run either. Bled some pressure off at the port and hammered on the tank, still no fuel pump noise. I know some vehicles will shut down fuel under some no spark conditions and wondering if this might be the case. Dont want to do a fuel pump if I dont have to.

Check and test the fuel pump relay and inertia fuel cut off switch.

Didnt see a relay in the book, but will call my brother & have him check again. Dont fuel pump relays usually go bad in continuous run mode? Fuse-20 amp was good. Inertial switch was checked by my brother.
