So it turns out the MLPS was bad. it was also the original one, so i had to repin the harness to use the updated one:   From there it was just a matter of priming the fuel system and it roared to life! Timing is now set, and of course it needs an exhaust system still. I backed it out of the garage to confirm that at the very least, 1st & reverse work. Brakes need bled again. But it runs! So this week ill be working on the interior since ive got a bad power window motor and the door locks dont work. Gotta fix the door panels and the center console. But its close to being a driver! Ok, progress Im basically done under the hood  new a/c condenser, new radiator, and the rest of the engine is now assembled. Im also replacing the a/c compressor and dryer and accumulator since im converting to 134a  New high pressure adapter fitting had the wrong thread pitch so i had to order a new one  ...and the a/c is now pumped down!  So i opened up the fuel pump housing:  its pretty gross, no wonder it didnt work
...and all rebuilt with new pump, strainer & float:  New tank, with rebuilt pump installed, along with a new valve & gasket since im guessing i tossed the old ones when i scrapped the tank  new galvanized skid plate from bronco graveyard  ...and installed!  Fuel lines are done, but when i went to hook up the vent line for the charcoal canister i saw it was all rotted out...  ...so i bent up a new one & installed it  With all that done i picked up oil, coolant, etc to get everything filled up:  Fortunately my first coolant fill was straight water because the tstat housing was leaking like a sieve  But that was a simple fix. So i hooked up the battery and keyed on to prime the fuel system. Had one leaky fuel injector oring (top of inj #1) which was an easy fix. So, i turned the key and....... ...nothing. So thats where im at now. The start circuit doesnt seem to work, im not sending power to the trigger wire for the starter relay, but the ignition multi-function switch is working so must be something else stopping it from starting. Jumped the relay and the starter cranks but the engine didnt fire so it may be an issue with the MLPS since it seems to be affecting the run circuit too. So it looks like ill be doing some troubleshooting... Surprised the wifey this morning. Maybe 6 months ago she had picked out a set of wheels for this thing. Last week i ordered them, and successfully got her tires mounted and balanced on em without her knowing.    Set the toe real quick...  ...and slapped em on!  Its gonna need flares to pass PA inspection...  ...and the money shot  Took some measurements, and it ended up right at 4" lift. Nailed it! Ive still got some loose ends to button up under the hood, but im hoping to have it running in another week or so... From there it was just a matter of putting the motor back together!  After cleaning the throttle body and replacing the EGR & IAC, the plenum went back on  New cap, rotor, ford racing 9mm wires, and a MSD ignition coil  ...and i think thats it? This week coming up i need to replace the a/c condenser (i punctured it by accident), which means conversion to R134a. Then radiator, plumb trans cooler, fuel tank + pump & filter, and then i think i can finally try to get it running! So, i made some progress on the 90 bronco. Stripped the motor down and changed the timing chain  The smog pump is shot along with all the air pipes, so its all going away   Its not easy to see, but they bolt to the back of the head  The holes are threaded, because when flipped to the other side of the motor a threaded insert goes in it, and the accessory drive bolts to it. Which means we can plug the hole simply by putting a short bolt in it.  No smog pump means no TAD or TAB, so the vacuum system came off for repairs and the removal of about half the vacuum lines  pulled the plenum  and then pulled the fuel rail so i could clean and then rebuild the fuel injectors  i changed the rusty (but otherwise apparently in good shape) spark plugs  The IAT was super gross so that got changed, along with the ECT since i was already in there  So in the process of the rebuild, i decided to get rid of the fire hazard that is the 2g alt  Just a small amount of grinding on this web, and the 3g alt fits right in there   bracket cleaned up & installed; reman alt installed as well:  I also tossed the junk Ford steering pump in favor of a Saginaw off an Econoline  bracket all cleaned up, with reman pump installed  and i deleted the OEM cooling loop on the frame rail in favor of a proper steering cooler off of a Superduty:  |
