So this may be a little lengthy but I appreciate any help that comes my way.

I bought an 87 ranger a year ago from a private seller and at that time it was running fine but after a few months I started losing engine power to the point where second gear was my last one that I had enough power to stay in. Truck wouldn't go over 20mph. now the truck floods the engine and wont drive and idles super rough
work done:
throttle sensor
Inertia switch bypass
Fuel pumps
injectors
Regulator
Fuel lines
Spark plugs
Wires
Icm
Timing chain and gears
It's been re-timed
straight pipe exhaust so no cats
air filter
Map sensor

other information: previous owner had ripped out Fuel pump wires when offroading and now has a killswitch in cab. When the truck starts it idles rough as crap, turn off Fuel, evens out, idles high but doesn't shake like crazy, then before it dies turn on Fuel pump and it runs super rough again and may flood out.

 

have you tried to get the ODD1 codes?

 

Check engine light does not work and there's no power to the scan port.

 

is that the one under the hood? if I remember there was more than one place to get the codes

 

It was under the hood. Passenger side. I don't think there is another way to check codes but I'm no wiz over here

 

I did it like this but I used a test light instead of the jumper wire

 

I don't think there is any power to my port. You just hooked up a test light the same way he used the jumper wire?

 

yes,

 

I'll definitely give that a try. Thanks friend

 

red cable goes to ground . test light point goes to one of the test ports

 

Something else to try


Run the truck till its warmed
Hold the accelerator pedal all the way to the floor, this engages the "clear flooded engine" protocol.
Try and start the truck, it should not start, the injectors should not be firing, if it tries to start, then one or more of the injectors is leaking
