Last night my BJ started to cut out, seemingly at random. I can hear the relay click over in the passenger footwell, sounds identical to turning off the ignition, then the engine momentarily loses power for a fraction of a second (I assume the edic shuts off the fuel flow) and then comes back strong. This doesn't seem to be correlated to anything. It happened at idle with a warm start last night, didn't do it at cold start today, was doing it cruising on the freeway but not at hot idle when I came off the freeway, but at cruising on city streats at 25 mph it did it. The only thing that has happened recently is a fuel tank replacement (but that was 2-3 weeks ago), and it rained like a mofo last night and this cruiser is NOT waterproof. :confused: :confused: :confused:

TIA,
:beer: B

How's the oil level? It will shut down on low oil level.
 
Oil level is fine--checked it. I have put a mech gauge on there cuz the dash gauge was so funky (read low) and the pressure was fine when I did that. Dash gauge is same as ever.

You're right--it does sound like when it's low on oil pressure like when you do an oil change and it shuts off on the first try at restart.

I just think it has something to do with the rain and moisture. Funky ground. Of course, that could be anything. Yippee. My two fav things: fluid leaks and electrical gremlins.......

On a side note, you can prefill the oil filter so the engine gets oil sooner. I've been doing that for a long time. It likely won't shut down then because it has oil fast enough, not to metion it is a little easier on the engine.

Good idea. Glad I've only done one oil change so far....
 
I kinda like the older 3bs with the oil filter pointing down, you could fill it and when changing it you did not cover the side of the engine with oil.

Once had a intermiten problem, turned out to be be a short int he wires at the EDIC motor.
 
I had identical symptoms with my BJ70 when I first got it. You could watch the edic cycle on and off. Took my booster/jumper cables and bonded the engine/ zero volt battery post and body and things stabilized. Great troubleshooting tool, those cables. Anyway, I repaired all the ground cables and its been fine since.
 
I had the exact same problem with my BJ-42. What happened was the edic motor got loose and would vibrate a bit and once it got to a certain point it would do a cycle which mean shut the fuel off then go back to the run postion. I tightened it up and havent had a problem since,
 
OK it's definitely an electrical problem--when I have my headlights on the relay clicks off the fuel flow about every 5 seconds. Pretty regular. I'm going after the ground straps tomorrow. Any other ideas? Might have to get a new fuel cutoff relay I suppose...
 
take the relay to the local computor geek hide out and get them to check it over for a damaged circit.
my 42 started doing the same thing when i sunk the glove box in a creek. it would cycle continuiously. i ended up pulling the plug and stalling the truck to stop it. Toyota wanted $750 back then for a new one. i bought a complete cruiser for $1000 and used the fuel contorl off it.
cheers
