You'll have to run a self-test to get the codes, which should help to figure out what your problem may be: Fuel Injection Technical Library » How To Run a Self-Test
Depending on the year of your truck, you'll either have two digit or three digit codes. 87-91 are two digit: Fuel Injection Technical Library » 2 Digit Self-test Codes 11-32
92-96 are three digit: Fuel Injection Technical Library » 3 Digit Self-test Codes 111-171

If the check engine light is flashing, that is BAD. That means the ECM has detected a problem with the engine that can cause damage to emmissions components (catalytic converter). As Bob stated, you need to find out what code(s) are setting to begin diagnostics.
