On the way home my 1987 Ford Ranger started to run really bad and started boiling black from the exhaust, seems to be flooding. (v-6, 2.9L, 4-wheel drive). Any suggestions?

 

its the EEC-IV system. need codes to help
whats the fuel pressure?

 

One thing you can check real quick is the fuel pressure regulator, It is mounted on the fuel injector rail, sorta towards rear of motor. Its a small canister looking thing ,most were chrome if I remember rite . Has a vacumm hose going rite to the top of it , , Has 3 allen screws on the bottom that mounts on the fuel rail ,, With the engine running , if you pull off the vac. hose an it shoots gas outa the top of the reg. ,, Thats your problem,, I had one a couple yrs ago . The guy pulled in the shop an the truck , was just a chugging black smoke , he said he live about 2 miles from the shop an it used like a 1/4 tank fuel to get there .,, dont do this on a hot engine , you dont want fuel spraying everywhere !!!!!!!
