HiTech Posted May 20, 2007 Report Share Posted May 20, 2007 WORKED ALL DAY SATERDAY ON THE 84 TPS CAR .CHANGED HEAD CARB DISTRIBUTOR ..AND WHAT NOTS ...SO HERE .S THE PROBLEM ..FIRE THAT LITTLE MONSTER UP .AND RAN GOOD FOR JUST A FEW SECONDS .AND STARTED BACK FIREING AND JUST WENT TO HECK ..THOUGHT THE SHEER PIN LET GO ON THE DISTRIBUTOR DRIVE .BUT NO PROBLEM THERE ..ACTED LIKE IT WAS RETARDING ..THE PROBLEM WAS THIS ..IT KEPT LOSING FIRE TO NUMBER ONE AND TWO AND THREE CYLINDERS BUT NOT FOUR .. NOT IN THE SAME SEQUINCE EVERY TIME ..IT ONLY HAS FOUR CYLINDERS TO BEGIN WITH .. IVE NEVER SEEN THIS BEFORE .I PULLED A PLUG WIRE AND ADDED A PLUG TO IT TO CHECK THE FIRE WHILE RUNNING AND IT WOULD FIRE GOOD THEN FADE TO NOTHING ..SO ONLY NUMBER FOUR KEPT FIREING .. ..... THIS IS WHAT WE DID ..... ................................................................................ ............................................................................ CHANGED ..DISTRBUTORS ... CLEANED THE POINTS ... CHANGED CAP. NEW ROTOR .... REWIRED IGN WIREING EVEN TRIED A NEW GROUND TO DISTRIBUTOR . CHANGED COILS ..BY PASSED MSD BOX ...... PLUGS .... . IGN .CONDENSOR ..JUMP THE DISTRIBOR STRIEGHT TO THE BATTERY TO MAKE SURE WE DID NOT HAVE A BAD TOGGLE SWITCH ..AND SO MANY OTHER THINGS ..AND STILL NO LUCK .. THIS PROBLEM STARTED WITH A STOCK DISTRIBUTOR IN IT ..SO ITS SOME WHERE ELSE I SUPPOSE ..THE ONLY THING WE DID NOT CHANGE IS THE BATTERY ..OPTIMUS .. NOT SURE HOW OLD IT IS .... KINDA WONDERING IF IT JUST CANT HOLD ENOUGH AMPS TO RUN THE IGN AND FUEL PUMP AT THE SAME TIME ..DIDNT TRY THAT ONE .. ..HAD THAT PROBLEM WITH ELECTONIC IGN ..BUT NEVER POINTS ..AND NEVER FOUND THAT TO CAUSE IT TO LOoSE THREE OF FOUR CYLINDERS LIKE THAT ....SO ALL YOU MOTOR HEADS COME UP WITH SOMETHING ....THANKS ..

poorboy Posted May 20, 2007 Report Share Posted May 20, 2007 Take it to autozone for a free scan from one of their diagnostic geniuses. Link to comment Share on other sites More sharing options...
neon14 Posted May 20, 2007 Report Share Posted May 20, 2007 Go get a neon, put a cage in it, and go race it. Its cheaper, plus theres no carb, distributor, points, cap, rotor. Then you could throw away your timing light. Link to comment Share on other sites More sharing options...

Whitey741 Posted May 21, 2007 Report Share Posted May 21, 2007 Said you changed distributors but thought I would throw this out anyhow. Is there any type of advance, eletrical vacuum or mechanical? Check the advance plate and make sure it is not loose or messed up. Electronically controlled I wouldnt have a clue but if the advance only can be disconnected, try that. Distributor bearings/bushings? Probably no help at all but just a shot in the dark. Link to comment Share on other sites More sharing options...
eduk8er Posted May 21, 2007 Report Share Posted May 21, 2007 I know Mike's been rattling his brain on this one. I hope he or someone can figure this out. I don't get to race until it's fixed!!!!!!! Of course, I was no help!! Mike, I know you don't want to hear this one...but what if we completely rewire the car? Then we know exactly how it was put together. Probably not the answer, but it eliminates a few guesses on how the system was wired. By the way, did Josh win? Link to comment Share on other sites More sharing options...
PAPA Posted May 21, 2007 Report Share Posted May 21, 2007 What about the wires? You didnt mention those. Ive seen weird things happen due to the wires . What motor are you running? I wish I had a answer for you. I hate it when things like this happen to me. Its usually something simple but it will drive you crazy until you find the problem.

NickHolt Posted May 21, 2007 Report Share Posted May 21, 2007 I'm certainly not an engine man.. not even close.. but have you checked where all the wires go through the firewall? We had a problem similar to yours a long time ago and finally saw the tell-tale burn marks on the firewall where a wire went through. Also, have you considered that it could be simply the battery with a dead cell or two? Nick Link to comment Share on other sites More sharing options...
97car Posted May 21, 2007 Report Share Posted May 21, 2007 What about the condensor, have you changed it. How about swapping out the battery with a known good one? Link to comment Share on other sites More sharing options...
lbeaver087 Posted May 21, 2007 Report Share Posted May 21, 2007 oldtimer, i was at the races this weekend racing , and was talking to one o the racers i race with and he said he was running bad and did changes like you did ,and it all came down to the battery. so i think i would put in another battery . plus i have seen when spark plug wires get hot they fade when hot or they just dont work as good as new . hope this will help you . louis Link to comment Share on other sites More sharing options...
HiTech Posted May 21, 2007 Author Report Share Posted May 21, 2007 thanks all you drivers none drivers ..i by passed the whole system except i used the power comeing from the main cable from the battery......... ..to power the distrbutor .............. and yes i thought it might have been that advance plate ...........so as price watched and helped with morrow support with jessies help we tore the distributor apart and found it to be stuck ............so we got all that to working properly ...........the shaft and all inside parts are fine ..so thanks for that imput ..now im with alot of you that said the battery ...........price can remimber i spoke of that later on after we had to give up ..........so i will try another one .......and if that dont work .. .....rewire the car .........nick i checked the fire comeing from his box and found it to be dead ........so i went around that with a new wire to the coil ......lol even my electrical brainster at work could not come up with something ........other than a bad distributor ......but the problem started with a stock dist ..........before we added this one ..........and it is points .......so not one of you have come up with a bad ideal ............some ive tried some i will ........im still open to anything and who knows ill go back and try some of the same things again ............. btw price ........typing is being charged to you also ..this is your nightmare that was forced on to me ..and you can have that dream back ..lol.... 20 years ago we had a miss in a motor and it drove us nuts ..but it didnt slow the car down ..and after we tore it down changed everything we could ..it came down to the battery ..and we found that by chance ..but it was a electronic system ..not points ..oh we changed the condensor .. .. price better know as eduk8er is going to owe everyone before to long ..and he.s only raced once on a round track ..he might have to go back to drag racen ..

RockStan Posted May 22, 2007 Report Share Posted May 22, 2007 Gary Chancellor had the same problem......... we went threw distributors and carbs and everything hell he even got a new car because of it but with the new car the miss was still there and was there even with new wiring new motor new everything the only thing we didnt change was battery and grounds he changed the battery 2 weeks ago and still had miss the only thing that fixed was when the 25 car hit him going into the turn it cleared up(sounds like a ground to me) so maybe you could try the same thing ............ get it running and have someone hit you going into the turn lol worth a shot Link to comment Share on other sites More sharing options...

1-Crew Posted May 23, 2007 Report Share Posted May 23, 2007 I'll assume you are running a Holley so this is not quite applicable but I had a similar problem once while running a Weber, somehow the emulsion tubes got left out while setting up the carb. When we put it on the track it ran pretty bad and when we pulled plugs, it was two white, two black. I can't quite figure that one out but I guess it got into some kind of mode where it pulled big globs of fuel on one stroke and not much of anything on the other. It would start out running so so, then go real bad after wet fouling the two plugs. Link to comment Share on other sites More sharing options...

eduk8er Posted May 24, 2007 Report Share Posted May 24, 2007 Mike, wish I could be there to help. sounds like you've been busy on that baby! I'm about ready to take the advice of some and hit it with something. Maybe Jesse can get the 7 running and we'll let him T-bone it. That might help!!! Do you need anything from me? It's the last week of school and we've been quite busy. Hopefully, things will let up next week. Did you change the battery? If we need to rewire, let me know and I'll come down to do the crawling and cuttin'! I'll hook up with you later. Looks like the weather is going to keep some of us from racing this weekend if the weatherman is right! Guess we'll see how things go. By the way...please don't give it away or sell it just yet.
