I have a 1990 f150 four wheel drive 300 engine with efi. I had the motor rebuild by a person that has rebuild a lot of engines. It hard for me to think all 6 fuel injectors are bad at the same time. Its try to start but will not. But every thing looks good I have never seen all six injectors go at the same time.The fuel rail has 50 to 60 psi and the injectors are getting power. Please help are my over looking something

 

Check the distributor timing. Pop the dist cap off and see that the rotor is pointing to cylinder #1 when #1 is at TDC on the compression stroke. Also check to see that you have juice to the coil and spark at the plugs.

 

Yes the rotor is pointing to cylinder number one when the number one is at TDC on the compression stroke and yes there is good spark at the plugs nice blue flame. thanks

 

Are the ignition leads connected to the distributor in the right order (correct firing sequence)?

Yes sir I have checked it and checked again. I think I will put all new injectors in it thats what I think it is. All the test I did point to that but I have never seen all of them go at the same time.

did you try a compression test ?

 

All six fuel injectors did not go bad at the same time, I'll just about guarantee that.

 

thats what I say but the test point to it
