Will Vaseline lock the engine if you prime the fuel pump with it on a 2007 grand prix

What engine ? could have 3.1 or 3.8 L No resistor ? for what ?
Noticed no Speed Cont. fuel pump relay. What are you talking about . Are you talking about no control for the fuel pump relay from the PCM/ECM engine computer ? The PCM Energizes the fuel pump relay for two seconds when key is first turned on . Two second prime of fuel system . When cranking the engine the PCM/ECM will only energize the fuel pump relay if it see's an input from the crank sensor .

Turn the key on , the fuel pump is computer controlled . The PCM - engine computer will energize the fuel pump relay for two seconds when you first turn the key on ! This primes the fuel system !

cant find the fuel pump on my 98 grand prix

the hose that goes to the water pump is usually the bottom radiator hose, the radiator hose that goes to the thermostat housing is the top radiator hose......cheers.

Are you sure that the fuel pump is properly installed? Have you tested the fuel pump circuits to see if they are working properly? Did you also replace your fuel filter? (It could be totally clogged up) Have you checked to see if there is any fuel pressure at the fuel rail or are you just assuming that the pump is not delivering fuel to the injectors? Have you checked your fuel injector circuits for power and for injector pulse from the EngineControl Module? Have you scanned your Engine Control module to see if you possibly have a Crank Sensor or Cam Sensor problem?

The oil pressure switch only keeps the fuel pump running once the engine starts. The fuel pump should run for 2-3 seconds when you turn the ignition switch to the "Run" position to prime the injectors. The oil pressure switch is the problem only if the engine will not continue to run on its own after it starts up.

it is inside the gastank u have to drop the tank

COULD BE MANY THINGS CAUSING ENGINE TO SURGE LIKE RESTRICTED FUEL FILTER.DIRTY FUEL INJECTORS FAULTY APP OR ACCELERATOR PEDAL POSITION SENSOR.
