Ok simple answer. Yes when these cars were brand spanking new they didn't do it. When they had perfectly balanced compression on each side of each rotor, they did not do it. When they had no carbon built up anywhere in the intake, engine, or exhaust they did not do it. Yes when the car was brand new it was able to overcome the fact that the computer was pumping way more fuel into the engine than it needed to start when the engine was warm/hot.

So yes, if I were to put a brand new intake, engine, ignition, fuel injection and exhaust system in the car every 30k miles, then yes my car would start almost every time for the next 30k miles. But for those of us in the real world, we install an aftermaket device so that we can get 125k miles or better out of our non-perfect engines.

The fact is that the early T2 computers dump too much fuel into the engine during a hot start condition, even when the cars were new.

Simply putting new injectors, ignitors, solenoids, or spark plugs can in some cases relieve this particular problem for a while, but it always returns. The use of a fuel cut switch or a fuel pump solenoid delay circuit quickly and permanently solves this particular problem in early T2s every time.

If you don't want to believe me then fine.

If you want to read a little more about this problem, or if anyone is interested in a delay circuit similar to one I built myself for my car check out this site:

From that website: That's because they don't want you to know you're being charged $98 for $3 of electrical components in a $5 plastic box!
Salguod, I'd be interested to know how you made yours. Others probably would too. I'm sure it would be a very simple circuit easily constructed by anyone who can read a schematic and solder components. This is such a common problem this info needs to be available the same way the TeamFC3S DIY FCD is.

 

LOL

Thats about right.... I actually had everything I needed to build mine lying around the shop except for for the transistors.

If you have a little electronics know-how, and if you have a good library near you try to find a Book called "The Encyclopedia of Electronic Circuits" by Rudolf F. Graf. In it, look up the "Precision Solid State Time Delay Circuit." That’s the one to build. Its pretty cheap and fairly easy to build.

Be careful though, if you really don't know much about electonic circuitry, then the $100 investment is still cheaper than a new ECU if something goes wrong.
