I have a 1970 LTI with TI ignition. The engine will not fire or start, until I release the ignition switch from the start position. If I hold the switch in the start position it will just crank the engine over. As soon as I resease the switch it will fire. Any Ideas as to the problem?

Re: 1970 Ignition switch problem
Sounds typical of a wiring harness problem where ignition continuity can be good/bad in the engine cranking position and good/bad in the engine run position of the ignition switch. A competent local auto electric shop can diagnose/repair this for you quite quickly... -
Re: 1970 Ignition switch problem
I'm no T.I. expert, but it sounds like the coil bypass circuit from the "R" terminal on the starter solenoid is open. The T.I. diagram I have for '66-'71 shows the production 18-ga. yellow coil bypass wire from the "R" terminal connecting to an 18-ga. pink wire that's part of the T.I. harness.Comment

Dave,
Has your TI amplifier been "upgraded" with a new circuit board? I had the same exact problem and was solved by replacing the "new and improved" board with an original replacement one.

Re: 1970 Ignition switch problem
Dave, I had a similiar symptom with my old 396 with TI. Turns out my problem was the timing was way retared after I put in the dist. Have you reinstalled the distributor? I would get a timing light and check your timing. Chris1969 Riverside Gold Coupe, L71, 14,000 miles. Top Flight, 2 Star Bowtie.Comment

Re: 1970 Ignition switch problem
I just recently purchased this car, and I know that the whole TI system was just rebuilt. I will look into this. Thanks all.Comment
