Runs like crap

96stroken and smokin · Mar 11, 2013

To start out I drove down to homedepot and came back out and on the way home I notice a power decrease. It just got worse from there I finally made it home and pulled these codes. P0264,p0267,p0273and p0282. Now the injectors were in stalled 3-4 months ago and have less than 300miles on them. I also in stalled a brand new from ford injector harness. Is it my ficm or injectors.

check what the icp pressure is, also fuel pressure, load test the batteries, check ficm voltage.

Check FICM voltage..

Sootie I don't have a scanner that will show icp. Also don't have a fuel pressure gauge. And ficm I would have to wait till it stops raining and check it manually.

I'd say either weak fuel pump or FICM...

So with a weak fuel pump is would throw them codes

P0264 - low circuit injector 2
P0267 - low circuit injector 3
P0273 - low circuit injector 5
P0282 - low circuit injector 8

2,3,5,8 all share the same plug on the FICM. I would start there and ensure your harness that runs between your FICM and those injectors, is plugged in really well. Take the bolts off of the top of the FICM and push on the three plugs on the bottom, ensuring all are seated well.

It could but more than likely with those low voltage injector codes the FICM is failing..

Ok I'll try that mdub707. Then I'll buy a new one then if the wire trick dosen't work.

First,I would make sure that the ficm harness is completely plugged in.

Agreed..

Just get yours repaired, no need to buy a new one. If you feel the need to buy a new one however, PM if you would like to sell yours, I'll gladly take it off of your hands.

If the wire trick doesn't work, you should also run a voltage test to ensure it's the FICM itself failing.

Just so you know, that plug doesn't have to be very loose to cause these issues, I've had this happen before myself. Truck ran like completely crap, would barely carry an idle, but voltage tested perfect across the board at 48+V. I went to remove it and the center plug basically fell off, it just hadn't seated all the way when I put it on.

Ok I'll try.but if I buy a new one from a sponsor wouldn't I need my old one for a core? And I'll check the voltage also

That's what I'm going out to try but it's a brand new harness.but I'm still gunna try

Just unplug all three and plug it back in,Make sure to hear the click noise when plugging...

Mdub707 · Mar 11, 2013

If it's a new harness, then chances are it didn't get plugged in all the way and just worked it's way loose a bit. Hopefully an easy fix bud.

Just take out the mounting bolts for the coolant bottle and you can actually pull it forward and slide the rear of it towards the drivers side fender and prop it up on top of the bracket it's mounted to, no need to drain any coolant. It should give you enough room to squeeze in there and remove the four mounting nuts holding the FICM down, lift it up and you should be able to squeeze the plugs back together. I use my left hand on top of the FICM and my right hand to sandwich the plugs in.

Mdub707 thanks I just tried it and it fell right down as soon as I slightly pulled it. I snapped it back in and no more codes. Thanks to everyone

Mdub707 · Mar 11, 2013

Nice, those are the good fixes, they don't cost anything.

Glad we could help you out bud. That's what we're here for! :toast:

Yes the free fixes are especially with all the trouble I have had out of it. Like I said I have only drove it less than 300 miles since I installed my injectors thanks to my intercooler boots but I finally got that taken care of with hair spray (i hope) they didn't blow yesterday day.
