Can fuel pressure regulator cause long crank?
Can fuel pressure regulator cause long crank?
Will a bad fuel pressure regulator cause a car not to start? A bad fuel pressure regulator can create a difficult to start or ‘ no start ‘ engine. If the ECU can ‘t measure the excess fuel coming through the fuel pressure regulator vacuum line, it will usually cause the engine to run rich (too much fuel ).
What happens when the fuel pressure regulator goes bad?
Fuel is the lifeblood of a vehicle’s engine. It is mixed together with air to produce energy that drives the car. There are many components of the fuel delivery system. Malfunction in any of these components can result to problems in fuel delivery. One of the most critical components is the fuel pressure regulator.
What causes engine to crank for long time before it starts?
When an engine cranks for a long time before it starts, either spark or fuel is missing or weak and each has its own reasons. Most of the time, the air / fuel mixture has been disturbed and there is too much air or not enough fuel.

Why does my Honda Odyssey crank for longer than normal?
A leaking injector is very possible. On a cold start, cycle the ignition key on to off several times. Each time you do that, the pump runs for 2 seconds. If you do that and get instant start, it’s a good bet you have a pressure issue. The question is, where’s the pressure going. My money is on the check valve/regulator.
