Mechanical problem of Ford F 150 with IT problem

I have a problem with a Ford F150 with 4.2litros engine pulls a multiple admission and you have no fault code. You don't light.

Hello friend you want you have problems with the gasoline pump you want not to send enough precion and that's why they are the shots because gasoline does not reach the cylinder thanks I hope that my help serves you.

Good night, check as the friend says, check the fuel pressure first, if this ok checks the ignition or spark advance that they call may be late or can have some inverted spark plug cable.

Hello, first of all, the truck fails from one moment to another or had some warm (read a temperature rise) because if you tell me that it does not have code your fault is clearly mechanical it could be due to defective spark plugs or worse if you have heated more than the account any burn admission valve now you should also check the distribution belt.
