I bought this truck almost a year ago I have replaced the fuel pump the camshaft position sensor the crankshaft position sensor the ECU and spark plugs I have no spark at coil packs and no pulse an the injectors I'm lost as to where to look now have checked grounds can anyone help me please ????

 

My first question would be to ask if you checked all the fuses?
We need power to the coil system and injectors. The PCM provides the ground at the right time for them to work.
Do you have any kind of test equipment to use like a test light (can ck for either power or ground) or multimeter?
Fuses can be easily checked with a test light , and you can check almost all of them with the light.in less than 1 or 2 minutes without removing them.
Let us know what equip you might have and maybe we can suggest the procedure to try.

 

I have checked all fuses numerous times with a multimeter and all the relays just don't know where to look for the next step thanks

 

With the key on , you should have 12 volts(VPWR) usually on a red wire , available to every coil. Also, injectors. The PCM supplies the ground for the coils and injectors to function at the right time. You can verify power to the coils and injectors, the easiest to reach, If you have that,then just pick anyone coil and now see if it is getting a round signal from the PCM when the starter is cranking the engine over. We know you need to connect to a good positive source to verify a ground.
Let us know what you find, thanks.
