Petersubaru Posted March 31, 2008 Share Posted March 31, 2008 On my "1986 EA82 Carbed manual", ..the odd time when going over a bump on the road the car completely dies out..with the key in the "on" postion I am Not getting any voltage to the coil,...but when trying to start the car, I might get 1/2 a volt..sometimes rocking the car will restore power to the coil...when shaking or moving any wires near the coil area or under the dash there is no change...just wondering if someone has any ideas on where the problem might be Link to comment Share on other sites More sharing options...
hooziewhatsit Posted April 1, 2008 Share Posted April 1, 2008 Have you checked all of the fusable links? Pulled them off, then put them back on to make sure the connection is good? -Dave Link to comment Share on other sites More sharing options...

Petersubaru Posted April 1, 2008 Author Share Posted April 1, 2008 Because of the intermittent nature of the problem, it has lead me to assume many things to be the problem..the fuel pump has been changed, new 12V wire to the fuel pump and grounded.. the coil has been changed out,.. also the fuel pump control unit exchanged, ..fusible links checked/replaced..what makes it more difficult and confusing, is that with every so-called repair, the car started up immediately, thus leading me to believe the problem was solved..

Nug Posted April 1, 2008 Share Posted April 1, 2008 Ignition switch worn out? Link to comment Share on other sites More sharing options...
Petersubaru Posted April 1, 2008 Author Share Posted April 1, 2008 Ignition switch worn out? Thanks for mentioning that idea..it was one of the things on my list above that I forgot to include that was already tried.. Link to comment Share on other sites More sharing options...
john in KY Posted April 1, 2008 Share Posted April 1, 2008 Is the coil bracket securely bolted to whatever it bolts to? If not grounded you end up with your problem. Link to comment Share on other sites More sharing options...
ivantruckman Posted April 1, 2008 Share Posted April 1, 2008 i had the same problem, it ended up being a corroded ground strap, their about 5 different ground wires on the engine Link to comment Share on other sites More sharing options...
Petersubaru Posted April 1, 2008 Author Share Posted April 1, 2008 the coil is tightly fastened...Ground strap has not been checked..provided there is one, might explain why when sometimes rocking the car or hitting a bump it either returns to normal or dies out..anybody know where the main ground strap might be located on a carbed loyale Link to comment Share on other sites More sharing options...
Petersubaru Posted April 2, 2008 Author Share Posted April 2, 2008 i had the same problem, it ended up being a corroded ground strap, their about 5 different ground wires on the engine ..that was a good call..it should have been the first wire for me to check..the ground strap on my car was ready to come off, just barely hanging in there, so this should take care of the intermittent problem..But, But, Link to comment Share on other sites More sharing options...
Petersubaru Posted April 2, 2008 Author Share Posted April 2, 2008 But, everything was running well, .. now the fuel pump/coil fuse keeps blowing, but when I ran a wire from the thermostat to the fuel pump, it seems to run with no problem...does anybody know if something in the speedo cluster could cause problems to the coil or fuel pump Link to comment Share on other sites More sharing options...
Cougar Posted April 4, 2008 Share Posted April 4, 2008 My info shows that fuse #11 ties to the coil and pump via a blk/wht wire. The b/w wire also ties to the rev sensor and then the feed to the pump is on a blu/red wire. The problem may be within the rev sensor. You could try running fused power to each of the areas, one at a time, using about a 5 amp fuse and see if blows on one particular circuit.

Also, IIRC, That fuse also powers the heater in the auto choke. Try unhooking the wire for the choke heater. I've seen that be the cause of repeated blown ignition fuses.

It's not in the dash. It's under it, on the drivers side wall. Just up above the hood latch pull. Link to comment Share on other sites More sharing options...
Petersubaru Posted April 4, 2008 Author Share Posted April 4, 2008 It's not in the dash. It's under it, on the drivers side wall. Just up above the hood latch pull. ...Not to add any more confusion here, but directly above the hood latch and the only item attached to the side wall as described above is the "fuel pump control box"...if this, is what you mean as the rev sensor,...this item has also been exchanged with no difference to the main problem...however, just above that FPCB and connected to the front of the dash is a 1.5"x1.5" cube with many wires going into it...is this what you are referring too as the rev sensor..Thanks Link to comment Share on other sites More sharing options...
Cougar Posted April 4, 2008 Share Posted April 4, 2008 The rev sensor is the control box for the pump. You should be able to see the b/w and blu/r wires running to it. Edit: Checking my info again it looks like the b/w power wire also runs to 2 connections on the ECU along with one of the check connectors.

Petersubaru Posted April 4, 2008 Author Share Posted April 4, 2008 I forgot to mention that when the car is running I only get 11.38V at the coil while the alternator is putting out about 14V Link to comment Share on other sites More sharing options...
Cougar Posted April 4, 2008 Share Posted April 4, 2008 I forgot about the carb on my first post but my info shows the ECU for a carb model also. Check the fusible links for a loose connection. That may be where the voltage is dropping at. Link to comment Share on other sites More sharing options...
