Tim's Ranger
I need your hand to get my son's 88 Ranger running again. Truck has been running great till just a few day's ago. It's an 88, regular cab, long bed. Powered by the 2.3 litre, fuel injected, non turbo, and stock auto tranny. Engine cranks, will run on starting fluid (process of elimination) can hear fuel pump run till the system is pressureized. Have 40 psi fuel pressure at the rail. Have power on one side of injector plug the entire time the key is in the run position. Other side does flash when cranking. But it will not start. We have found a good size wire torn and bare. Looks like it's a ground, ending at the coil. But don't see the other torn end of same wire........
ANY help is greatle appreciated...

So this is the question.Why will the truck only run on starter fluid and has fuel pressure?

I have not ignored your bare/ lose wire I just cant think why that would keep it from starting since it starts with starter fluid( I am not an expert)

Did you try to start it with air duct off while fiddle with buuterfly. How about the different fuel pressure tests I mentioned. Are you sure you have gas in the tank. Did someone put water in the tank. Have you tried to start it with the starter fluid again

Yes I moved the cable and linkage and tried to start it, and didn't make a difference. It will star on Starting Fluid. I'm going to syphon some fuel out to see what it loks like. I got the truck inspected and licensed just a couple weeks ago. And filled the tank with fresh fuel.

Stil trying
Well we've been out of town abit and back at it on the Ranger. We put a new fuel pump and sending unit in the tank this afternoon. The fuel gauge didn't work either. Well it still won't start, but $122.00 later we did get the fuel gauge working.
I read something about a "High Pressure" fuel pump. Now that Tim has the hose going washing off between the bed and cab. I guess it's time to lay under it. Yes he's gonna get wet too.

We haven't changed the fuel filter yet, our local parts place told us there were several different choices. Haven't watched fuel pressure to see if it drops no. It it does what are we looking at? Befor we changed the in tank pump, we had 40psi at the fuel rail.

it should not drop more than about 8 psi in 5 minutes after turning the key off. how many cycles did it take to get to 40 psi. you might have 2 filters an inline and a cartridge

Air duct is clean, gas is fresh, only been in clean tank a couple weeks.Will check the fuel pressure to see what it falls to. With the other in-tank fuel pump in, it hit 40 psi soon as the ignition key was turned to the run position.

Ok now, we gave the pressure drop test almost 8 minutes, if the gauge dropped at all it was maybe a pound. Checked for fuel in the hose from the fuel pressure regulator, and don't see any! Still won't start on it's own. We did check the inertia switch last week, wasn't triggered....

If it runs on starting fluid but won't run on the gas being pumped by a working pump then it must be the gas,
Drain and refill the tank with new gas.
Any electrical issues? Might need the PCM to be re-flashed by Ford.
