Ecu on the way.  It could work

[etk300ex]

it didnt.

Time for propane yet?

[fasteddie]

really go through the wiring harness corrosion ect can cause odd things like these to happen check any splices connectors ect. have seen same type issue multiple times and ussually leads to a corroded splice for a sensor or power to ecu

[etk300ex]

I've been over and over it, I can't find anything

[MrMindless]

you've got to strip all the loom and tape to find that sort of thing

[etk300ex]

All but under the dash has been striped and inspected

[fasteddie]

which leads to another possible solution when the truck shuts off do you loose interior lights radio ect? or does  just the engine shut off? if you have not checked under dash could be supply issue ie ignmition switch ect... what distributor does it have? any type of ignition module other than ecu? the other thing i would do is watch the primary voltage for the coil with a meter and see if it drops when truck dies or if its loosing only secondary ign.

[fasteddie]

also check for signs of oil inside distributor. have you checked the resistance of the pickup coil? should be 185-265 ohms . i would check as soon as it dies.

[smichaelR22]

it doesnt really die, it just runs like crap with no power.  Eric pulls the disconnect and then its fine for another 10 minutes

[etk300ex]

I have done a full tune up including coil.  It has an ICM but I've yanked on all the wires and shook it, tilted it up-side-down etc and cant reproduce the issue.  I could pull the distributor out and give it a look see. 

[fasteddie]

so you have ruled out the coil rotor cap wires plugs.... i would check the air gap on the pick up coil it should be between .008-.016" do not use a magnetic feeler gague to do this if that is within spec and not covered in oil or oil residue i would replace the icu wiggling turning over ect are all good tests but the icu is all solid state from what i have read so may not get you far i think the best way to prove its failure would be to install a spark checker between the coil tower and cap and watch for the spark to weaken as the truck runs. if the spark is indeed weaking as the truck runs it would have to be caused by the icu as it is actually firing the coil and not the ecu. this running condition could also be caused by a weakening fuel pump but to me just shutting it off then resatarting should not casue it to run good if it was the fuel pump. unfortunatley there is not an actual test for the icu only to rule out all other ignition related components.

I might work on it this weekend 

Check for oil in the distributor was also suggested to me by some yota guys. 

I swapped fuel pump with smike at big dogs in 2012


Did make it to the newark car show though! haha

Looks like FLX4X4 dominated haha

We parked on the outer edge so we didn't infect any of the nice autos with our cooties.
