1976 lincoln help Sign In

Unsure Hope someone can help me. I bought a 1976 Lincoln continental from an individual who bought it from original owner. Car had been sitting in garage for 20 yrs. Has less than 38k miles on car. Has 460 ford engine. The person I bought it from claimed to had it running to drive it to his house, then had dropped the tank and cleaned it, installed new plugs and plug wires, fuel pump, distributor, cap, rotor button. For what ever reason he could not get it running again. I believed him. My mistake. No way car was ever running. Has an electrical problem we have not figured out yet. I am not a mechanic so what I am explaining is the best way I know how. Anyway, we used a piggyback wire under the hood to bypass something to try too get it to even fire. Would not fire with just turning key on. We pumped out the tank and put 5 gallons of hi-test gas and a can of Seafoam in tank. Did get car running but, it is missing badly, no power. It seems as only 2 plugs are firing, as I could remove 6 plug wires and could tell no difference. Went and bought new plugs. Did not help. The next to the last plug on each side were the only plugs that made a difference if plug wire was removed.Not sure what to do now. Any advice would be greatly appreciated. Thanks

That's a bit much

Well, that tells me a whole lot {sarcasm}


All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.



Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.


2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.


3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.

4) If all of these things check good, then you would need to do a complete compression test.

Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

Would definitely start there first. Make sure your battery is fully charged, the ignition system is disabled, and the throttle is wide open when you do your compression test.





Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Compression check was what we were going to do next as did not know what else to check. We did get it running, just seems to be on 2 cylinders. Question I had is why do only 2 cylinders seem to be working? Wouldn't think 6 cylinders lost compression. What should I be looking for to be problem? Unsure thanks

This isn't a Harley, it isn't going to run on two cylinders. To answer your question about why it may be doing this, you need to do the tests mentioned by the others. You have a 37 year old engine with an unknown history. Until you know for sure the engine internals are in good enough shape by verifying the compression there isn't any point in looking for anything else. You need to systematically test and verify components to isolate where the issue lies.

Since you are doubting the last guy actually cleaned out the tank, you can also try unhooking the suction line off the fuel pump and running a piece of hose into your gas can. See if it runs off of that. If it does you have a bunch of junk in the tank and lines.

With a car this old, anything can be suspect, and yes you can lose compression on 6 cylinders. Time to test it to see whats going on, then get back to us with the results to see what needs to be done next.
