  1. What could have gone wrong here? (switch engines, no compression)

    I have a 1991 3.0, which was knocking. I took the engine from a 1999 3.0 w/ a bad frame but running engine and put it in the 1991. I put the distributor and upper and lower intake from the 1991 on the 1999 engine. To switch the lower intake I had to take out the pushrods and then tighten...
  2. Anyone know where these vacuum lines go? 1991 3.0

    Take a look at the pic, these are the vaccum lines that come off the back of the intake manifold, right near the distributor. You can see there are 3 lines that don't have hoses. I swear I labeled these. But somehow over the course of a project taking much, much longer than it should...
  3. Use sealant for upper intake reinstall or just the gasket? also, torque specs?

    1991 3.0. For some reason my factory manual seems to omit any details about upper intake reinstall. Do I need any sealant in addition to the gasket or just the gasket by itself? And what are the torque specs for tightening down the upper intake?
  4. Use sealant for upper intake reinstall or just the gasket? plus torque

    1991 3.0. For some reason my factory manual seems to omit any details about upper intake reinstall. Do I need any sealant in addition to the gasket or just the gasket by itself? And what are the torque specs for tightening down the upper intake?
  5. Final torque (or how much of a turn) on rocker arm bolts once I have zero lash?

    I switched my lower intake on a 99 3.0 L. Now assembling things back up, I'm putting the pushrods back in and tightening down the rocker arm bolts. Once I tighten them down to zero lash, my manual says to tighten each down to 24 foot lbs, regardless of cam position. This seems like it would...
  6. Is it possible to put a transmission and engine into 1991 3.0 together?

    I'm putting a new engine in my 1991 3.0. It would be nice to put the engine and trans together outside the vehicle and then put them in as one unit, but it looked like that might not be possible. Seems like that first cross member (riveted to frame) would get in the way? Anyway, just double...
  7. Clearance issue removing clip from disconnect on hydraulic clutch line

    Anybody run into this? I have a 1991 3.0. I have had a variety of 2nd generation 2.3s and dropped transmissions every few months it seemed, and I thought the hydraulic line fitting with the clip worked fine (at least compared to the one they used to have where you pushed down the white plastic...
  8. Where to buy hydraulic clutch line fitting by itself?

    At one point I had acquired a hydraulic clutch line that was made of braided flexible steel instead of the hard plastic line that usually comes with it. It made dealing with any clutch issues so much easier. It didn't catch on things when installing or removing, it was easier to bleed because...
  9. Confusion on ignition system wiring...

    I have a 91 3.0 which has had erratic periods of no starting. Most of the time it started...except when I needed to be somewhere. I THOUGHT I had found the answer, but after looking over a trouble shooting manual, I am confused. I had previously tested the 12v red and green power wire going...
  10. Running engine on a stand - electrical questions...

    I built a stand to run a 3.0 vulcan on. I'm planning on putting a 99 engine into my 91, so once I combined engine parts on the engine, I wanted to make sure it was working before I put it in the vehicle. I've seen a few videos of people running engines on stands, but I have never done it and...
  11. Explanation for this resistance value in relay coil?

    I was testing my EEC power relay coil in my 1991 3.0 and noticed something strange. The resistance value of the control coil was 1 (infinite). This would seem to indicate that the circuit was open, which it shouldn't be. Yet, when I applied 12v to the two spades of the control coil, there was...
  12. Part number for replacement EEC Power Relay (brown)?

    My power relay is giving me some odd resistance values so I would like to replace it. They gave me one at advance (YL-240-C-12V+D5) but I'm not sure it is the correct one. It has an extra spade, which could be OK since there is a dummy hole in the female side.....or maybe it's not the right...
  13. ANYTHING else that could be causing this no spark issue?? WTF

    1991 3.0 isn't getting a spark as tested at individual plugs and at the coil. The wire that carries the pulse signal FROM the distributor to the ignition control module seems to be working just fine -- I get a flashing LED light whenever the vehicle is cranked over. The wire that carries...
  14. Wire terminals for harness clip that connects to Ignition Control Module (91 3.0)

    I have a 91 3.0 that I've been trying to figure out why it has no spark. I narrowed it down to the ignition control module because the ICM was getting a pulse signal in from the distributor but was not sending it out to the coil. I replaced the ICM and still have the same issue. On closer...
  15. What year trucks/other fords have compatible distributors?

    Hey Everyone, I'm going to be headed to the junkyard in the near future to see if I can find a replacement distributor for my 1991 3.0. (1) What other year and size rangers are compatible? (2) Are there other fords (not necessarily rangers) that would be compatible? Thanks in advance!
  16. Where is my PIP sensor? 1991 3.0 w/ distributor

    Not getting a spark. Tested it, and the ignition coil is not sparking. Tested the two wires going to the coil and the coil is not getting the pulse signal from Ignition Control Module. Located the ignition control module (in my case on the side of the radiator), and it doesn't seem to be...
  17. Some 1991 V6 3.0 ignition coil questions

    Spark tester attached to the coil isn't showing a spark. There are two wires leading to the coil: a pink and green one, and a yellow and brown one. the pink and green one shows 12V with the ignition on and the yellow and brown one shows nothing. Is this right? Also, attached to the bottom...
  18. Torque specs for lower ball joint castle nut and pinch bolt for upper ball joint (1993 2wd)

    Anyone know what the torque specs are for these?
  19. Removing thermostat housing on 94 2.3

    The two bolts that secure the thermostat housing to the block seem to be blocked. One is blocked by the alternator bracket, which is so close to it, I can't get a socket on it. The other is blocked by the timing belt cover. Did you have to remove the alternator and bracket and also the...
  20. What size belt to just power the alternator (no AC or power steering)?

    Anyone know what size belt I can get to just power the alternator? My power steering is messed up and before I buy the parts to mess around with that, I figured I would just go manual steering for a while. Pretty stiff when the truck is sitting, but not bad at all when moving. But, I would...
