Checked voltages at the relays.
Next I'm going to check at the IDM connector.
Ill have to dig up the pin out diagram and see what I find.

Here are the pics of testing the relay power supply pins at the distribution box.
All other pins had no power.

First the IDM relay. Fixed

12v here,

6v here,

Now the PCM relay pins. Fixed

12v here,

12v here,

6v here,

Good? Bad?

I said this wrong.
The PCM is the relay pins on the bottom and IDM on top.

Per the pic above,

Wires 30 & 86 should have 12v at both locations.
30 is the horizontal pin at the relays.
86 is the top pin at the relays as shown in my testing pics from above.

IDM- Fixed
30- 12v
86- 6v

PCM-Fixed
30- 12v
86- 12v
87- 6v

So somehow I have half the voltage I need to pin 86 on the PCM.
And 6v on wire 87 where there should be no voltage.
Going to try these tests with the IDM disconnected just to see if my readings change.

Fixed the quote.

Also pin 30 is 12v at all times like it should be.
No other wires have any voltage with the ignition off.
So I have a short somewhere.
Going to ohm both circuits after disconnecting the PCM/IDM connectors.

Pin 86 at the IDM shorts to pin 87 at PCM even with all connectors and relays removed from the power dist. box.
Pulling out power dist box and going through wiring now.

Hey, just a quick easy suggestion, but have you checked the icp sensor? Mine had a lot of the same symptoms as yours, and it turned out to be a faulty icp sensor. I never checked voltages or went that far, I just tried the simple test of unplugging the sensor, and boom, it ran great other than throwing a CEL. even had similar AE readings and codes as you when it was doing it. Just a suggestion

ICP sensor is good.
Checked it with another sensor and same results.
Ohmed the IPR circuit from plug to PCM connector and ohms out correctly.
Still can't figure out where I'm getting the voltage back feed.
With the relays removed there should be no power to pin 87.
But I'm getting 6v on the IDM pin 86.
And 6v to pin 87 at the PCM relay.
Readings taken with ignition on.
With the ignition off only 12v at both pin 30s, which is normal.
Kinda lost right now.
So far the entire harness has ohmed out correctly.

I would try unplugging the Idm and check. Where does pin 86 and 87 with the 6v end up at.

I've got my 96 in the shop I can take some readings and see what mine are

I'm showing 8.2 VDC where you are showing 6 VDC

Crude AF but you prob can understand...

Ok tested again once I put the harness together and charged battery's.
IDM connector removed, instead of 6v now 7.5-8v.
IDM connector installed, same results.
Starts right up and dies immediately.
Quick pics of startup log-



RPM

ICP

Duty Cycle

Still have IDM Failure code P1298 for both KOEO and Buzz Test.

30 terminal is power to relay
87 terminal is energized relay power
flow.
85 is relay ground side of coil.
86 is power side of coil.
I would jumper 30 and 87 together without the relay in place and see if it starts. If it doesn't I'm pretty sure you have a bad idm.

I will try that however, I have already swapped the relays around with no change.

Another weird thing is when I put the chip back in and do the Buzz Test I get the P0605 ROM error...
But still have the P1298 during KOEO.

I just did a Google search of those 2 codes and found on another forum t g at they relate together when the Idm has been modded but it did not keep there engines from starting or running just cel with codes. So I'm not sure anymore.

Yeah, I got those codes with a swamps idm... You should try as I said with icp sensor unplugged, I had multiple bad sensors, especially if they are not Motorcraft, it's worth trying

Tried that too.
Both Motorcraft sensors.
No Bueno.
Also my ICP tracked with DC on the above charts, so I don't think that's my issue.
But just in case I have a new one in the mail.

Anyone know the best place to buy a reasonably priced IDM?
I know heavydoc had offered to lend me one for testing but by the time shipping was paid,
I'd just rather go with a reman that has a warranty.
Worst case Ill have a good IDM to send to swamps.
