Lost some time troubleshooting a drivability issue in the '90 Bronco. Started running rich but no codes. Took me a longer than im willing to admit, to figure out the ECU had failed.
In addition to the usual capacitor failure, we also had a resistor blow
A buddy fixed the ECU for me, but im my troubleshooting i replaced the injectors, assuming i had a sticky one. After reinstalling the ECU the bronco ran just as bad if not worse; some more troubleshooting revealed that one of the reman injectors had failed and was stuck open, just dumping fuel down the intake. So back apart she came:
I ended up putting the original injectors back in (the ones i had rebuilt myself about a year ago) and now its back to running just fine again! The moral of the story is, troubleshoot better, and dont assume the ECU in a 33 year old vehicle is still good!
So with the tcase & trans full of fluid, we fired it up to go for a test drive.
The second i rolled the window down, the driver window motor gearbox broke:
...and on our way home the 32 year old motor mounts gave up the ghost and the fan ate the fan shroud
So i rebuilt the window motor gearbox and got new motor mounts installed while i waited for the shroud to show up
So that done i took it for its second test drive.....
....and theres something wrong with the transmission.
The shifts are at weird places, and it was making noise going in/out of 2nd.
I went over to the trans shop and the tech jumped in with me and he agrees, so im dropping the bronco off wednesday morning so they can look at it. Thankfully it has a warranty, but this still sucks because im betting its coming back out.
So lets see, we were working on the '90 Bronco.
The tuesday after we came back from vacation i picked up the E4OD:
transmission is in:
transfer case & driveshafts are in:
original starter is cracked...
...so i decided to upgrade to the PMGR starter:
wiring for the starter redone:
and the starter is in:
....which means she's done!!!
So i put together a video going over, in detail, how we installed and wired the Autometer oil pressure and transmission temperature gauges in our '90 one-ton Bronco Project:
Here we go again
Got my reman solenoid pack in
...but of course that didnt solve my issues. So the trans is getting rebuilt. I drove it over to the local trans shop yesterday morning to BS with them. I dont know if its a good thing or a bad thing that he knew all the issues with both the early and late E4ODs, but it certainly made me feel better having a conversation with their mechanic about all the issues as opposed to someone just reading the update manual. Seems like the guy knows his stuff. Long story short, theyre rebuilding it.
Skidplate and driveshafts out
OEM starter? Think its the original one from 1990?
I was gonna say "They dont make em like they used to' and put it back in, but the nose is cracked:
tcase is out
Trans xmember is out
...and trans is down
Dropped off at 10am this morning, its in their hands now. In the meantime im going to clean up the skidplate and trans xmember, and rebuild the tcase.
Monday June 19th (13 days) we leave for the 25th East Coast Bronco Roundup. Depending on how this all plays out, she might still get to drive this thing there. We'll see how this all plays out.
