TDS?? Theft Deterrrent System. They are a number of interlocks with starter enable relay, fuel enable, door ajar, hatch ajar, key in ignition , etc. that if not working properly could cause starting problems. I think I would start with fuel and or starter relay first.
Regarding the starter soakback. That problem does not cause the engine to quit after its running. It manifests itself on an attempted restart. Sometimes an immediate restart is good but as the heat "soaks back" to the starter, a restart after 10 min or more is no go. I've had to wait 2-3 hours for the heat to dissipate enough for a successful start. Again, this is a typical 60's,70's problem and I don't know if its applicable to our C4's.

TPS (throttle position sensor) is attached to the throttle body---will not cause a no start. YES it does sound heat related to me--there is a time frame when under hood temperatures actually
increase after turning off a engine at operating temps. The temperatures rise after turning off the engine BEFORE starting to decrease. The fact that the cooling system (cooling fans and water pump) is not working after the engine is shut off---causes the engines metal parts to become hotter. It very well could a electronic component under the hood absorbing this heat and going open circuit---the term as "Dragon" used applying to the starter is "heat soak"
IF the starter is engaging and spinning the engine over at it's normal speed---then once again you OR a mechanic need to determine what is missing (fuel or spark) WHEN it will not start.

Vette(s): 1989 Convert. It's HERE ! ! ! This is my first 'Vette. Most likely my last toy as I am 71 years old.
Finally a resolution. Would you believe s 3 1/2 bad injectors ..... the 1/2 was intermittent. After 2 - 3 weeks of testing and trying thats what it came down to. When OHMING ot the injectors they must read between 15.8 and 16.9 OHMS. Also if you use a NOID light it must be bright or the injector is suspect. When taking the intake off we found loose bolts and a set of RE-POP injectors in it. The car only has 52,850 miles on it. Injector replacement already ? ? ? Do NOT trust RE-POPS. The new injectors cost almost $100 each and I know that I can get them cheaper but I hve to go with my mechanic. Boy anm I glad that's over....
Thanks for all the help andd suggestions guys....Be the first to like this post

Check out the wire harness junction directly behind the battery. I just loaded a picture of it to the forum.
