So I was driving my car the other day, I parked it up. Went somewhere with my boy, came back to my car and it wouldn't turn on. Immediately I could tell I'm not hearing the pump turn on. I checked the button in the trunk(it's pushed down), I checked all fuses under the hood (all working) checked fuses under the dash (all working), then i changed the CCRM and still nothing. I did find a harness on the passenger side kick panel look a little burnt. It Was a 5 prong relay, i changed that still nothing. & I had changed my fuel pump 2 months ago with a Stealth 340... Just a FYI. I have a tune date next week I'm trying to make so if you guys have any suggestions please state them. Thanks CaFords

what size fuel relay and wires did you run?? it might be drawing more power than the relay can supply, or the wire gauge might not be big enough.. one of my folkz had a similar problem when he upgraded to a bigger pump.. he changed the relay to a bigger amp relay and hes good now..

unless you upgraded the wiring to the fuel pump. you more than likely burnt your ground connection somewhere. which would cause low voltage reading.

Thanks guys. I just rewired the fuel pump with a switch but then I put the wiring back to stock with no on and off switch and it started to work again. Weird but oh we'll it's working again.
