Hello , I am dealing with this problem, I replace the transistor from the fuel pump. Engine stars, no smoke, but no rev after 3k rpm, why ?

Hey
Check the fuel system. Air in the fuel system can damage the injection pump. Most likely
the injection angle adjuster in the injection pump is defective.


TECH recommendations


Checking the content of the correct type of fuel in the tank
Check for leaks in the relevant system
Check the connected cables and tubes for breaks, damage, etc.
Crack points / abrasion marks on fuel or injection lines.
Checking fuel line connections (quick couplings).
Control of leaks in oil lines.
Control of the condition of tee fittings.
Inspection of inlet and return fuel gaskets at the injection pump.
Checking the tightening force of empty screws.
Checking the correctness of fixing of joints and seals.
Fuel filter check.
Clogging, leaks, air or water in the fuel system.
