Author Topic: Serious Q's about 1986 GT Conv 90gtverrt ¯ Member # 1437 posted                              Ok here is the scoop....my Ex-Girlfriend gave me her 1986 GT Conv.....its in really good shape. It just wont start....easy fix allready found the problem. One other problem it has is that it just shuts off every once in a while. Like the TFI problem. I have replaced the TFI and Coil for her but it still does it. If you let it sit for a while and cool down it will start right up. What other possiblities could it be? Also how hard is it to convert to manual? Also how hard to convert to MAF. I may just stick a carbed 351W, leave the wiring harness for the computer and swap in a stock motor every 2 years. Well let me know. mike Posts: 1199 | From: Livermore, CA | Registered: Jun 2002  |  : DaveG ¯ Member # 1606 posted                              When the car dies after it's warmed up, check to see if you're losing spark or fuel. If you're not getting spark and you say you swapped out the TFI module and coil, check to see if you're losing your PIP signal. This is the electronics in the distributor. If you're not getting fuel, well that's easy enough.

So should i just replace the dist? What else can i check?

Have you checked the Shrader valve when you are having problems getting it to turn over? -------------------- R.I.P. Willie G.

Your money would be better spent on pullies, 3.73's, and an off-road pipe ...and maybe some 1.7 roller rockers to make those heads breath a little better -------------------- -SLOWER TRAFFIC KEEP RIGHT- Posts: 5132 | From: Bay Area, CA | Registered: Dec 2001  |  : 90gtverrt ¯ Member # 1437 posted                              First thing im gonna do after i fix gthe starting problem is swap the AOD out for a tremec.
