yes it did accidently by my landlord, It's his truck I'm trying to grt running, I changed plugs, plug wires and fuel filter, fuel pressure should be between 55-61 psi I gauge tested it has 38psi with ignition on. EDI electric system
your problem then is the fuel pump. replace that first.
did you remove the distributor??
