ok so on friday i took the girlfriend out to dinner in tacoma, camaro was running great, got to gig harbor and i went to the bank, when i put the car in reverse it died, put it in park started right back up and was on my way. went about 200 feet down the road and it died at a red light, took about 12 tries to get it to finally start again. drove it about 1/4 mile and parked it and when i went to go home it wouldnt start. after trying to see if anything came loose or was broken it started after about 20 minutes of waiting. got it to the same intersection as before and it died, so i pushed it into a parking lot and kept trying to start it, battery died. then after about 20 minutes of waiting it started up again. i had it towed to a shop and they said they refuse to work on my car. so i left it there until just now, and it started right up no problem and i drove it home. now im kinda scared to drive it again until i figure out what that whole thing was about.

i have had the ESC code 43 since the swap was finished

one header bolt is loose cause i cant reach it, could it have heated up some wires?

aaron might bring this up but would those 3 fusible links (that i have not fixed yet) be part of it?

last time this happened my distributor cap got warped inside, but i checked mine and its fine

has gas, spark and air

any ideas?

Could be ignition module, or pickup coil. Check for spark next time it dies.

I also like that the shop wont touch your car. Laughing

@ Mike: Shifter wiring will NOT make the car die. It will also not prevent start, it merely prevents cranking.

Dirty TB or IAC has done this to me before.

Why wouldn't the shop look at your car?

my advice about the fusable links, cut them out, put in real fuses, and run them direct off the battery. i figure the less wires in hot places the better.

based on the fact that you are cranking but not starting, and the fact that it is dieng... i am going to suspect spark bigtime. look at all that stuff. you can look up on TGO how to check things like pickup coil and ingition coil.

stupid question but where is the pick up coil?

also one of my headers is loose by the coil, would that excess heat in that area cause a problem?

could the ignition module be getting super hot?

Pickup coil is in the distributor under the rotor. Ignition module is in there too. Header wont hurt those.

No no no...

There is a very good reason Chevy did it that way. For starters, battery = acid. You want as few wires going there as possible. Secondly, fuses pop as soon as there's even a small overload. Fuseable links cook off slowly and only blow in cases of massive overload or short.

Run all the fuseable links to a junction box, run the battery charge wire to the junction box, run the alternator hot wire to said box. Run a solenoid on the fender to prevent hot no-start with headers.

Do not put fuses inline for anything other than the amp, do not run more than three wires off of the battery (solenoid hot, block ground, chassis ground).

oops i should probably fix that....


anyway i took apart my distributor, cap and rotor are fine cause they are like 2 weeks old,

distributor didnt even have an o-ring, oil was everywhere, the little star contacts and rings on the pickup coil were all rusty.

and one last thing, the dizzy was a tad bit bent

my solution......brand new distributor

and header is now all good

Yup yup Good to hear you got it fixed, Luke.

I have found that reman distributor tends to often be cheaper than rebuilding the old unit. I think Brandon just posted a topic about that yesterday. Laughing

yeah its way cheaper and plus i have no idea how to get the pick up coil out, i tried for like an hour and was just like im gonna buy a new distributor. works great now,

i swapped out my oil press. guage to see if that would fix my problem and it didnt, i know i should probably buy a new guage and wire it in but i like stock guages Surprised what would make mine peg out and not move, could the sending unit be bad?

Sending unit.

I'm assuming when you swapped the 305 you went to a two-unit setup? Or did you keep the three-wire one?

If so, I have one here. Yours if you come out to Lakewood and get it.

Luke, if, instead of buying all these brand new shiny things you bought fast ugly parts, your car would be much faster.

Or you would end up like me, going for quantity rather than quality, and end up with many many slow ugly cars. Razz

That's a little over zealous and opinionated if you ask me. They use fusable links for many reasons. One main of which is the high load they carry. Notice on anything mid-late 90s GM stopped fusable links and used the large fuses in the underhood relay compartment.

You can never be over fused as long as they are good connections and properly sized, AND IMHO any circuit protection should be as close to the battery as possible. Fuse box is an exception because the box itself is "fused" by the links. Any wire on the + side can burn your car down if it's between the battery and the first link/fuse. This is why the car gets power off the heavy starter lead and IMMEDIATELY fuses. IE the firebirds with the battery on the opposite side of the camaros have WAY long power wires running to that starter. Todays batteries don't acid and leak like older stuff. No problem running wires off the battery if don't right, safe, and connected properly.

I think putting the fuesible links up to the battery is crazy. The battery only stores power. You need it as good as connection as you can to the alternator, its what supplys power while the car is running.

If your alt wire goes DIRECTLY to your battery, then hook it there. But the way GM wired it is down by the starter.
