2.9 really hard to start

[motaaa]

EGR pressure transducer, for the EGR to function correctly it needs to be there, removing the egr alone, without swapping to a non EGR computer is going to make the engine run like absolute crap.

what vehicle will have a non EGR 2.9 m/t computer?

1988 and newer...did not have a EGR system (California emissions equipt maybe different?)...therefore, the ECM (main computer) for these trucks were designed for that. Sometimes when folks swap in a newer engines they are not aware of that and have some runability issues, that are very much correctable. This comes with trying use a non EGR engine with a older ECM that is looking for a EGR signal. When that happens, the ECM still tries to compensate....giving runability side effects.

i dont think something like that would cause it to not start right away..
and as far as i know the ECU and engine are 1987.

i checked my sparkplugs/wires/dist/coil and everythings working as it should. she is running a little rich but shouldnt that make it start easier?

I doubt that it would make not start too.

true, that on cold start up you need to have more fuel to aid in starting. Like all things...too much of a good thing, is not so good.

many things/sensors have input as to what air to fuel ratio gets put in for starting. Hence, that is why you hear/read "get the codes" so very often.

I finally got the codes on my truck this morning & its telling me coolant temp sensor.
I am having the same hard start issue that you have plugs where all carbon & wet from gas.Truck is running to rich.

That will do it - you can ohm it out to check it. Go to fordfuelinjection.com and look around at the section on sensors. There's a table of resistance vs. temperature.

that was the ECU engine temp sensor not the gauge?

yes

 

[motaaa]

did you replace it? did it fix the problem?
