View Full Version : Engine cranks but won't start

06-21-2005, 03:29 PM
1996 prostar 190 less than 200 hours.

When cranking no fuel comes out of the injectors, the only way we can get the engine to start is to dump fuel in the throttle body chambers, then it start up.

The electrical is fine, new batery, the pump is fine, the filter was changed, etc... The boat was bought recently and ran fine for the test drive, and after the trip to her new home. We didn't check any voltages, although we swaped fuel pump relay with injector relay(I think) the're the same anyways... Any help would be appreciated. Thanks

How do you know the fuel pump is ok? Have you pressure tested it?
Does the fuel pump "charge" (run for 2 sec) when you turn on the key?
If it doesn't, then it's likely the fp relay, or the pump is shot.
DO you have pressure to the fuel rail, or throttle body?
There are several threads on issues like this.

The pump does "charge" when turning the key, haven't pressure tested though...Is there a valve on the line that we can connect to? Anyways, I though that the pressure was fine since when it did start, it would keep running.The fuel injectors kick in after startup.

Looking into old threads for similar problems.Thanks.
