90 Corolla Prostart remote start install

[Craner]

Hi there, just wondering if I could bounce something off ya. Im a licensed Tech by trade.

I have installed a CT-5072 Prostart in my 90 Corolla, I have the same setup in my 2003 ford 150 and my wives 1998 Pathfinder, all with no issues.

Reason I put it in the corolla its the vehicle I need for driving back and fourth to work, since gas is $4.50 a gallon.

Well the issue is, I start the vehicle via remote, vehicle will run for about 10 seconds then just turn off. It will restart run for 10 seconds and quit.

First thing I would think of TACH line, which is on the negative wire of the ignition coil. Well than I thought I would maybe try on the negative side of an injector. Still no avail.

Car runs perfect on the key.


Thanks
