I need a little direction here please. I have DTC 35, 36 84, 99, and now 29. The truck will not start and if it does it usually will not until the SES light extinguishes. The starter is good, cranks hard, batties are 12 v each. I have fuel to the drain valve, I pulled the fuel line off at the injector and barely had a drip when cranking. I still need to run down some of the wiring but it is too damn cold out right now. Any advise???
