2007 chev colorado fuel pump
First I would check for a stopped up fuel filter or just replace the filter. When you remove the fuel filter, look at the fuel that comes out and see if there are beads of water in the fuel. If the filter is ok and no water is in the fuel, you need to check the fuel pressure. Some Auto Parts stores will lend you a fuel pressure test kit. Throttle Body pressure is around 18 to 24 psi. For port tuned injection 40.5 psi to46 psi. Depending on the type of fuel injection you have, if this pressure is there, turn the ignition switch off and see if the pressure remains at the pressure you had with the ignition switch on. The pressure may slightly drop lower and then slowly drop off 3 to 5 psi after 3 or 4 Minutes but not back to zero or near zero in a short period of time. If the pressure is 10 or 15 psi lower then stated above, you may have a fuel pump check valve in the fuel tank that has stuck in the open position, or the fuel pressure regulator has gone bad and leaking. If the fuel pressure regulator has gone bad usually the fuel mileage has dropped off, and black smoke would have been coming out the tail pipe, the engine would have been idling rough.

Why the anti-thief device is keeping my truck from starting?
I replaced my computer at 53,000 miles and it starts up OK now with an occasional issue with starting like it has crud in the line or something, but the resetting the key after a miss does require the 15 minute wait. Had to do it once since the computer was replaced, but the issue before was the anti-theft system would shut it down after starting every time requiring a tow truck to get it to the shop. $700 for the computer chip replacement.
