At first checked fuel pump, had power to it but no fuel. We replaced fuel pump probably didn't need to. We also put in new fuel pump relay, now it will prime but won't pump on cranking. Replaced CSPS. Still no fuel with cranking. Help

Hello,

This sounds like it could be a problem with your Camshaft Position Sensor (CMP). Your vehicle's Power-train Control Module (PCM) uses the signal generated from this sensor to send duty cycle pulse width signals to the fuel injectors. Without this signal no fuel injectors will be powered open, hence you will have a fuel related no start condition.

I have also included in the diagrams down below vehicle specific information on the CKPs. Please go through these guides and get back to us with what you find out please.

Thanks,

Before I spend more money on my son's truck. I read in your article 'How to fix an engine not running'. I have fuel prime but no fuel flow when cranking. I have spark, it starts with ether. Checked injector voltage 12 volts with key on 10.8 with crank and just saw theft light with theft code 15. We've already dumped $200.00 into it.
