Question about 1999 GMC Jimmy
A couple of things to check, when the engine is turning over, do you have spark? You can disconnect one of the spark plug wires, insert a screw driver in the end of the wire, hold the screwdriver 1/4" away from the block, crank the engine over and see if you have spark.
If you do have spark, borrow or purchase a fuel pump pressure gauge ($40 to $50), connect it to the fuel injector rail test port (looks like a tire valve stem with a cap on it) crank the engine over and record the fuel pressure. You should have 55 to 60 PSI. Make sure it does not leak down more than 5 PSI after you stop cranking the engine.
Good luck, let me know.
