Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello and Welcome to Justanswer, My name is XXXXX XXXXX I am here to try and assist your with your question
have you replaced the fuel filter yet?
By your description you are running lean.
Yes i have
Couple things to check is the fuel pressure on the fuel rail. Should be around 32 psi at idle and increase to 42 psi on acceleration. The fuel pressure should not drop but rise under a load.
another thing to check is the ign timing
with the spout connector unplugged timing should be 10 degrees btdc and the timing should advance with the spout connector plugged in.
Yes it is ok I also took it to the ford dealer they said it was a vacuum problem. I repaired all the vac lines. still doesnt work. Timming is right on
How did you check the timing?
what was the fuel pressure at at idle and under a load?
I checked it with a light. Then the ford garage checked it and the fuel pres also
did you unplug the spout connector?
do you know what the pressure is?
should i have vac at the egr valve all the time
dont remenber but I changed the pump and regulator on the advice of just answer but the truck runs no better
no only under a load on the egr vacuum at idle no vacuum on the egr valve
If I apply vacuum with a hand held pump to the egr should i be able to stall the engine
yes or idle very rough
what are the codes from the engine computer?
I dont have them here but one was egr not opening. another was to lean
I can understand the lean reason itis running bad
the no flow could be egr valve is stuck closed
could it be the computer
I changed the egr valve no change
did you change the sensor on top of the egr valve
and or could have no vacuum to the egr under a load
the computer could be bad But I doubt it
how does it idle?
it idles good
I think the sensor came on the valve I just pluged the new one in
I took the catilitic converter out awhile ago could that have any effect on this it did the same thing with it in there but it was all broken apart
Usually there is a sensor on top of the egr valve. it does not come with one. Did you transfer it over? If it did not get transfered over and is missing. it will not work the egr valve and you will have no flow.
did you check for codes after you replaced the egr valve?
Tell me more about the cat
did you replace it?
yes they were still there.or back. I just took it out and didnt replace it
What is covering the egr holes? Tell me more about the cat
I dont know what you mean about egr holes
i took the cat out and put a pipe there
did any cat material get into the muffler. Did you run the van with the exhaust off before putting straight pipe back in? Did you put the o2 sensors back in?
I replaced the muffler at the same time. o2 sensers are in. Yes I ran it with no exhust same thing
Is the egr valve back on the engine?
how far is the timing advancing under a load?
I dont know i didnt check it under a load. the ford garage said the timming was ok. When i apply vac with a hand pump to the egr it has no effect
That will not cause the concern. you are having. More than likely the egr is not opening probably frozen. You said you put the sensor back on top of the egr valve
There was no sensor on top of the egr valve but there was spot for a plug and i pluged it back in dould the sensor be somewhere else
No it goes on top of the egr valve this is a 93?
yes 93 all that was there was a plug and a vacuum port
White sensor goes On top of the egr valve need to get it back on.
are you maby talking about the vacuum control
sounds like you are talking about the egr control solenoid not the egr valve
it was egr valve it bolted to the engine and has the pipe running to it at the bottom and goes to the exhust
needs a sensor on top of it for it to work
it must have come on the new one as it had an electrical plug to it
do you know what a spout connector is?
Were is it located?
on the drivers side looks kind of like a fuse
by the ign module right? Did you unplug it to check the timing?
yes i did. the ford garage also checked the timming
did you replace the ignition module?
i see you replaced the distributor ?
I did but with a used one
yes replaced the dist
did you replace the coil?
yes replaced the coil
You are looking at a bad computer, or a fuel problem. Before replacing the computer I WOULD GO BUY A FUEL PRESSURE GAUGE AND double check the fuel pressure. if ok replace the computer.
Or you can take the computer apart and check
Remove the computer. Remove the cover for the circuit board. Check for a burnt blue capacitor wires two of them on the circuit board, and or discolored capacitor. There are only two blue ones. On the circuit board. The farthest one from the 60 pin connecter is the bad one.
Go to radio shack and buy a 10uv @ 100v capacitor. Replace it and all will be good.
If not burnt then replace the computer with a rebuilt one
