Double check your fuses. Battery connections then look at grounds.

If you find any wires that are brittle and green/white crusty. They need to be addressed.


After your visual inspection I would get a DMM and check the voltage at the computer and check resistance on the grounds there.

I dont have pin out info for your year.

well marcus (lol) the fuel pump is not clicking my guess is its not getting power due to the computer not cycling. when i turn the key on the check engine light does not come on to show that the ecm is cycling.. but who really nos. i just put a clutch in her (bleeding it was well just wow) ran just like normal for a week then this. i checked the grounds i removed and reinstalled.

If you can find one for less than 20 its a good deal.

I have a ford ranger 2014 model, the check light do not come on when i turn key on. T

I have a ford ranger 2014 with same problem. I observe that when i unplug the ECU, the check light shows but soon as i plug the middle socket,it goes off. I have swapped an ecu but same thing.
