You can save a lot of money by buying a pressure guage set up. Find out what pressure you have at cold start. as the Engine warms,the pressure changes gradually until the engine is hot. Secure the guages and go for a short drive ,while you observe what is happening to the fuel pressure.

You cannot begin to fix a problem with Kjet until you know exactly what is happening to the pressure.
NEVER start diagnosing a Kjet fault until you have a Perfect ignition!!!
How do you know it's fuel if you haven't at least installed a new rotor cap and leads and plugs?
Have you checked the coil or resistors?


My brothers 380 had the same problem until last week ,when the fuel pump relay failed. A new relay has completely cured his cold and hot start cranking problem.
