Well, I have now gotten my 1983 240 DL to start, but only two times. I saw a post that mentioned that if you have your grounds for the ignition harness and engine harness on the same bolt on the intake manifold it can cause interference. Well, I guess that was probably part of my problem, because I separated the engine and ignition harness ground leads and tried to start my car, but it would only turn over. (I should note here that when I took the bolts off the intake manifold to separate the grounds, I found that I had really good fuel pressure in the fuel rail, because it sprayed and leaked out while I had the fuel rail loose.) I messed with the three plug connector to the distributor(I've got the Chrysler white cap distributor) and it didn't really seem to do anything. I then decided to use a wire to jump between B and C on the plug, because I know that will produce spark at the distributor cap and at the spark plugs. I jumped B and C and I could see the spark at the spark plug and hear it in the distributor cap. I then messed with the three plug wire more(just kinda wiggled it) and then noticed that I could hear sparking in the distributor cap and the idle valve buzzed for a second or two, but wouldn't stay buzzing. I wiggled the wire plug more and could hear sparking and the idle valve buzzing intermittently. I then reconnected the round plugs and tried to start the car. The car turned over and then started coughing like it was getting intermittent spark. I suspected the fact that if the round plug was wiggled it would intermittently make spark. So I wiggled it more, heard spark in the distributor cap, reconnected the round plug and tried starting again. This time it did start and I let it run for a few minutes. I then tried revving the engine, but when I put pressure on the gas peddle the engine instantly died. I wiggled the round plug more, didn’t hear any sparking in the distributor cap and tried to start again. It would turn over, but wouldn’t start and wouldn’t cough – I suspect due to not getting any spark. I repeated the above a few more times and then it finally started. But the second I touched the gas peddle it died again. I haven’t been able to get it to restart since, but then again I only had a few more minutes to work on it before I had to leave for class. Anyhow, is there anyone who would agree that the ignition harness is bad? I got it used, but itz a newer one and I can take it back for an exchange. My last ignition harness the one that car with the car originally would do the same thing of, if you wiggled it, you could hear sparking in the distributor cap. But come to think of it, it never made the idle valve buzz. So if anyone has any tips, pointers, basics, whatever, please post or E-mail me! Thanks. PFHarper@cox.net
