Atoadaso I f*kn Atoadaso
more breaking, Cant drive this thing 20 miles without taking a **** on me.
I had a start condition where it would run for about 10-20 mins then die, and cool down and fire up for another few minutes and die. so I could see I was getting fuell, as the TBI was spraying as my kid was cranking it over, so I pulled the distributor, and for a distributor I basically rebuilt, aside from the shaft and cam gear a few years ago, It looked like ****.
The Dizzy Shaft was spent, and since that shaft and a gear seems to cost only $10 less than Cardone at O'reilys (minus cap and rotor) I went ahead and ordered one.
When I got it I was kinda disappointing, because it looked super cheap, even the ICM looked like a 4 year old glued it together. but I installed it and it fired up, but it usually fired up when it was cold, So I re-timed it, and it seem to be running well again, so I take it around my neighbor hood which is pretty big.... all is good, pull up to the house, hold the revs up.... and it stutters and dies, this time it does not start up again. come out the next day, nothing. sooo now that the distributor is new, gotta be the Coil, which is also only 2 years old. replace the coil..... nothing, so then I decided to do some trouble shooting since I was stumped, and I should of done this the first time!!!
anyways after a while I found a great website to trouble shoot no start conditions. http://easyautodiagnostics.com/gm/4.3L-5.0L-5.7L/distributor-mounted-icm-tests-1
Anyways I skipped there step of getting a little led light to check for ignition control to the coil, and so it was difficult to tell if the light was pulsating with my test light, it did seem that it intermittently was, so I yank the brand new coil off and went to autozone and they benched tested it..... and it failed, so then I had to drive to another autozone to get another coil to replace that one.
I get the new coil, throw it on, No Dice! still wont start, I bench test the Coil I originally took off and it passed. So now I think its the brand new distributor I just got.
I go ahead and get one of those little leds like the Link suggested and checked for a pulsating light on the control wire again, The Led definitely makes it easier to test in my case, and as I crank it over the light would start on, and then shut off, and after a few more cranks, the light wouldn't come on at all. so now its safe to blame my new distributor. as I was curious what was the culprit, I tested the voltage of the pickup coil and the link supplies what range of voltage it need to hit to make it a good pickup coil...... It never came close. so pulled the distributor out and returned it to O'reilys for a refund..
Jumped on Rock auto and found a distributor that claims to be 100% cpu tested and comes with a brass cap and rotor for the same price.
best quality distributor ive seen for the 88-94 trucks.
Put it in, fired right up. re timed it. running good.
