Hello, I am having an issue with a no start problem on my 1995 GS 300, it all started with a bursted heater hose, i made the repair, test drove it, then park it for about an hour until my son got ready for work, when he got in the car it wouldnt start! Some noted issues i have seen during this are: no tachometer reading and no check engine light illumination at all! Any help would be greatly appreciated!!!!

 

What all was replaced when fixing the coolant issue? At this point i would say double check the battery, any cables around the alternator, and anywhere else you guys might have been working on when addressing the cooling issue. The cooling system itself does not have a lot of sensors, other than one on the radiator lower left side when viewing from the drive seat, lower right side back when viewing from the front of the car, but should not cause the issue you are describing.

 

It was a split heater hose on top rear of engine, not really close to anything else that would have any effect on a no start, at least not that i can tell. It ran fine right after repair, just after sitting will turn over fine just no start. Really is puzzling how it all happened!!!
