    2003 Ford F150 Dedicated CNG No start

    I hope I'm posting this in the proper channel. I just bought a 2003 F150 (dedicated CNG). I changed the fuel filter and did the fuel injector cleaning with the MP5. After doing so, I cant get the truck to start. Engine does turn over. I found the fuel reset switch under the kick panel but it wasn't tripped. I disconnected it and reconnected it but got nothing. Its almost as if the fuel rail doesn't have pressure. I pushed the shredder valve in and there was just a little bit a fuel. Is there another switch or how do we go about depressurizing the system after its been depressurized? Truck was running fine before the filter change and injector cleaner went in. Any advice is greatly appreciated.

    Mine is a byfuel but after the regulator on the low pressure side should be 105lb of pressure, if not check you solinoid voltage
