Default Stuped Mecanic Timming Issue

just to clarify for every one The Mecanic. will be know as The Stuped


The Story.

I buy my 1986 vette. 4 weeks ago.

the main problem of the car was poor idle. missfire. backfire very poor aceleration. and very bad preformance. 1 or 2 death cilinders.

I know the problem is tuneup. (spark plug, check sparkplug wires, full filter. and mostly timming. (ingition system)

the best part. the engine at list was running.

I decided to look for a mecanic (The Stuped). wich I did.

The Stuped told me that we have to make an appointment to go and see the car. that way he will get a good idea what he have to do.


Couple of days later we meet at my house. The stuped go and start the car. he listend to the engine for a couple of minutes

he say that the engine have couple of death cilinders.

So here comes the Stuped part..... Out of the blue he disconect one spark plug wire out of the distributor with the engine running. imediately the engine stop.

The stuped plug the wire back again to de distributor. and guest what. the car never start again.

The stuped say that i most make and appointment to take the car to the stupid shop, where The stuped can check the engine better.

but the stuped told me he was very busy at this time, so he told me to call him back in 2 weeks. after that he told me that he have to go .

As you all asume I will not be calling The stuped again. so I will try to fix this problem my self. with every one help here.

My main problem is to get the car to start again. I know the problem is timing. but in order to set the timing right to 6 degrees I have to start the engine.

is there a way to move the distributor in a position where at list start the engine. or any advice is welcome.

remeber before the stuped disconect the plug the car was running. bad but running. so the timming most be off but not to much.

I be here all day checking this thread

If the motor was running on 6 cylinders and a firing cylinder was disconnected, the motor could die. If all he did is disconnect 1 wire and reconnecting it would not allow it to start up again, maybe the wire was damaged when he pulled it off the plug and the connection has been lost. Try replacing the wire before you start playing with the timing.

Just to clarify for readers who (like myself) would be inclined to post

Stuped Mecanic? (and leave)....

It's spelled Stupid Mechanic. [Major] Mis-spelling gives you the appearance of being the stupid one. But, some might not notice you're in a different country (panama).

That said, if you know the problem, why are you posting here? You don't know the condition of the car without performing more thorough tests, right? Sounds like it never ran right.

You could have anything from a bad balancer, to mis-set timing, to bad spark plug wires, to a blown head gasket.

Have you done a compression test?

Pulling a plug wire won't hurt anything unless it was done in a manner to disconnect the plug boot from the wire. And, how can distributor timing be altered unless you (or "Stuped") had it loose? You didn't say the distributor tie-down was loosened?

If you know how to work on cars, you know the procedure to set base timing. It's the same for all gen 1 SBC motors. Google it.

Check to make sure your balancer hasn't slipped. The timing mark will point to the crankshaft key.

Check to make sure your wires are good. If you're not sure, buy new ones. Check your plugs too.

We can't fix your problem unless you make a fair effort on your own.

Wow. You definitely need to find a mechanic you can trust.

If it were me I'd do two things: 1) replace all the spark plug wires and 2) pull & inspect the plugs to see if they indicate which cylinders, if any, aren't running.

But please be very methodical in doing so---do things one wire at a time & be sure to write down or photograph where everything goes so you are sure you can put things back where they came from. It's possible one or more of your wires are already crossed so check what you see against your FSM & common sense.

Bad mouthing a mechanic that you probly try to get you to give his 'best cheapest price' for work, is counter productive. most of us on here that help folks are mechanics in one form or another, I've read most of your posts and threads, bad mouthing someone behind their back is infantile and doesnt have anything to do with tech. , is also a bit whiney, seems the issue you have is equally shared by you and your 'mechanic, you are not exactly in a part of the world where corvettes are common. hope this helps, Btw, good luck

you are right Greggpenn I need to do more testing before i jump into conclusion. any way the 383vett sugestion. have solid ground since before that move. the ingene in fact was running. also I forgot to mention. the Mecanic the Stupid . pull the wire very hard and fast. so maybe. just maybe the wire is damage. also there is no way the timing move. just by pulling the plug. But I sure like to ajust my timming once the car start.

I will check the plig wires. also will check sparks plugs for starters. if any body can give me more light in what ealse to check are very welcome

also please forgive my english. spelling is very hard for me.

I have nothing agains mechanics. even I was very happy when the mecanic take the time to go home and check my car. what I dont like about this person. was . he toch my car and stop working. and he just dont care and tell me he dont have time for me in maybe 2 weeks. I did not like his actitude. Iam not a mechanic so for me it will be more dificult to solve problem if the car is not running..

like I say I will document my self as much as posible on ingnition system. and try to started again.

There is a red wire that feeds into the bottom of the distributor on the drivers side. Make sure that is pushed up in there good and hasnt come loose.

1357 is the drivers side. 1 is closest to the front of the car, 7 is the rear

We dont know if your distributor is in right but lets assume it is.
Check your firing order and make sure all connections are good.

One step at a time. Youll get it sorted out.

FWIW, you can check the timing while cranking. The engine does not need to be running.

I shouldnt have said "under" the distributor more like down the side.
Youll see a number of wires that go in the bottom. THeres a clip that is supposed to hold them all in. Clip could be broken and the wire not making good contact.

You may be working on this awhile ironing little stuff out this is normal fare when getting a C4 that wasnt super well maintained. Be patient and stick with it. Once its right youll be real happy.
