my 98 gtp starts great every time but will die in a matter or seconds. there is no security bulb on the printed circuit of the cluster so im not sure if it is even equipped with security. fuel pump is running every time at start-up. n e 1 seen this or n e suggestions please! thanks

Bad fuel pump resistor. GTP L67 has a two speed fuel pump.

thank you iam also wondering of a clogged fuel filter but it is just too common. it is the same every time. like there is enough pressure to start it but not enough to keep running.

It is always a good idea to start with the fuel fiter especially if it is old or has over 20-25K miles on it. Also, you can check fuel pressure at the front fuel injector rail at the fuel pressure regulator Schrader valve to make sure it is in specs.
If all else fails the fuel pump resistor is the most common problem with GTPs starting up fine but stalling out in the matter of seconds.

You're welcome and thanks for the feedback. Before you replace the fuel pump hi-speed relay make sure it is not the fuel pump resistor. They get corroded from the weather, age and elements due to the location. You can run with it bypassed for a few days or weeks and it won't hurt anything until you get the part. See link below to see what I am referring to. Good luck.

The bypass procedures actually bypass the resistor.
