Warm start issue / FiTech 30020
Quote from fljunge81 on June 7, 2019, 1:41 pmHello to all, i am Florian from Austria and new in this Forum.
I hope i could find any help.
My car is a Checrolet Camaro 1988 with a new Crate 350 Engine and a new FITECH Classic EFI Throttle Body System 30020.
I have the following problem and dont find a solution to fix this.
Cold Start - perfect !
Driving - perfect !
Idle an Performance - perfect !
Only issue: Car wont start when parked after driving in operating temperature.
after cooling down everything works great again.
Any idea?
Regards, Florian

We also have checked these:
Voltage: OK
We moved the ECU in the car to prevent heat problems
Fuel Pump relay works when switching to ignition
Fuel Pump relay works when cranking
Fuel Pressure is okay
Ignition works perfectly
EFI gets RPM signal
When giving a short spray of brake cleaner while starting - car runs an drives again,
driving around some miles, back in the shop after some minutes same problem.
No trouble codes in Handheld
any ideas? i am getting crazy 🙁

Something that really helped mine was using an efficient gear reduction starter. In my case, a 1995-97 LT1 starter.
