F150 is a Ford model truck, not GMC.
But at any rate, since I don't know if you have a Ford F150 of some kind, a 87 GMC S15 or some kind of 89 GMC with a V6 I will suggest taking the ignition module to an Auto Zone and having them test it (A free service). Also test the fuel pressure.
If a tune up and fuel filter has not been done in some time that could very well be an issue.

TAKE VECHICLE TO AUTO ZONE THEY WILL SCAN IT FOR FREE TO SEE WHAT TROUBLE CODE YOUR PCM IS GIVING YOU.

need to know how to change the fuel pump, do i have to drop the fuel tank or can i get to it from under the back seat
