Burnt burb resurrection (It's mine again!)

didn't actually check that yet but it runs perfect and never faulters,, then just looses spark n dies whenever it feels like. the little bit of fuel draining out of the injectors after it dies is another matter.

for those that haven't followed much....
it runs great for a bit and then just shuts down like the key was turned off. sometimes it'll start right back up. then dies again when ever it feels like it. sometimes it wont,... has no spark at that point.
 
ECM didn't fix it either... so I bought every sensor I could think of... that's todays project.
 
I's be looking for a bad wire or fusible link thats breaking the connection --sensors dont usually go bad that often,and wont just kill the spark if they do,unless it has a crank sensor,those can do that...or a pick up coil in the distributor,if it has one...
 
the oddest part and what's leading me to a sensor is it will start right back up every time... unless its gotten warm. when the motor warms up it wont even pop back off... just crank and crank. till it cools down.. then it'll start right back up usually... it doesn't even need to be real warm to do it... 4-5 minutes of running.... and it always seems to do it at idle or BARELY off of it.


I don't know about the sensor wires or the ecm wires... but I ran a set of +/- wires from the battery straight to the coil once too with no luck
 
Have you tried logging data yet? I bet if you did we could find the problem fairly quick.

I'm going to bet on a frayed/cracked wire insulation somewhere causing problems.

Especially based on how this burb started with a fire....

I was having all sorts of speedo issues when warm based on some old wire insulation.
 
daylights running out on me I guess.... time to start looking at it.... I'll see what I can pull apart on the harness
 
I had issues with the part of the harness where it crosses over the back of the engine behind the dist. Kill my junk dead, shake 'em and all good. Hit a bump, dead.
 
You ever replace the injectors?

I had to replace one once that had a random, misfire, wouldn't always work, and another one a year or so later that would just open and stay that way, it filled the intake bore every time you'd turn the key on.

I was frying all sorts of ign modules from a short in these wire.

It will be hard to find, but necessary.
 
I was just looking at that bundle of wires... have to pull the dizzy to really get at em.. I hate that.... not a big deal except that even a dizzy wrench wont turn the bolt out:doah: May have to pull it again anyway though
 
this thing is getting me too flustered....:confused: With everything else going on I don't know if I can handle messing with it..... Bout ready to break sh1t then cry. Bad part is im kinda on a deadline because I need to egt my rav4 sold... cant do that till this is reliable
 
Distributor bolt on the TBI motors sucks. I've massaged my wrench to the point that i can get a few degrees of turn out of it though.

Keep calm, and work through it. Sorry to hear about all you are dealing with.

In my opinion, as much as these things are frustrating, they are reasonable. And you can methodically work though solving a problem, and once its solved, its solved. I appreciate the clarity in mechanical work vs. the rest of life's problems, and use it to clear my head. Best of luck!
 
um.... electronic spark control huh:thinking: reeaaally I may have to change that:haha:
