There is no MIL, no indication of anything wrong, and everything is working until it will not start. The intermittent behavior does not trip a DTC so I can't read a code to complain about. The engine cranks briskly but will not start. Testing shows the plugs are firing and when I've checked for fuel it was pumping, but then after testing, the engine started. I'm thinking its in the fuel pump system as I replaced the fuel pump at 97,000 miles which was this spring. the ground wire to the fuel tank was badly corroded when I cut if of so I removed about a foot of it and soldered a new section on which was fitted to the tank with a stainless steel fastener and copper anti-seize for added conductivity and prevent corrosion. After that repair it was working fine for the last five months until this intermittent problem has raised its ugly head. After failing to start four times in about three weeks it has now continued to work without incident for the last two weeks. Anybody got any ideas on where to look?
