Are you sure it's flooding or starving itself of gas? Rent a fuel pressure gauge from auto zone and check your fuel pressure is exactly what it is supposed to be. Fuel pump can warm itself up and and kinda fizzle out so check when warm and cold.

1989 mpv mazda does not start on cold mornings and days


I'm assuming the engine cranks with the starter but does not start and run.

check the operation of the cold start injector. This is a separate fuel injector that injects fuel into the intake manifold to help richen up the mixture for cold starts. It operates on a timer that is linked to a sensor that measures engine coolant temperature. Once warm or the timer runs out, the cold start injector is turned off. Other things to check:

Fuel pressure too high (floods engine through cold start injector), engine coolant temp sensor or intake air temp sensor is stuck at full hot (doesn't allow enough fuel for cold starts), fuel injectors are leaking (floods engine with fuel).

Check the fuel pressure regulator. Pull the vac line after it is warm and see if it is leaking gas into the vac line.

Engine keeps flooding itself, and wont start when warm


leaky fuel injectors or a bad fuel pressure regulator could be the cause. check the fuel pressure. should be 3.0 to 3.5 bar.

1989 truck stalls when hot.


Have you chg. fuel filter? If so, best to do a fuel pressure test, sometimes( not always) when the pump gets warmed up they can loose a little pressure and thats all it takes just a few # under recamended p.s.i and the truck quits running, you may hear the pump run but its not putting out the correct pressure until it cools down and it starts working again, but after a while quit all together.

454 ci gm turns over hard backfires timing ok acts flooded


Check fuel pressure, and regulator. A leaking regulator gives a warm engine more fuel [ it does not like it] a cold motor does. same as a flooded motor. Good luck
