how long has it been since you replaced the fuel pump and filter?

there is a possibility that it could cause numerous issues, including shifting and braking problems(w/ABS). The vehicle is doing adaptive strategy each time you reconnect and drive. Vehicles have to go thru 3 drive cycles, and this doesn't mean 3 trips to the store and back, to readjust after memory is lost from battery interruption.

Knock sensor may be bad causing idle to retard to stop spark knock . Carbon buildup in the cylinders on piston heads or around the valves can cause retardation as well as overheating .

In order to give you a solution to your problem, I need to explain a little bit about the valve train in your engine, the engine itself, and how it works.

1.You have an Internal Combustion engine. It is a Four Stroke engine. The engine has a Cylinder Block with cylinders inside. There is a piston for each cylinder which goes up, and down. The piston/s are connected to a crankshaft. The crankshaft turns the transmission, which in turn turns the driveshaft, to the rear differential. The rear differential has axles, which the rear wheels are bolted to. The four strokes are , Intake Stroke, Compression Stroke, Combustion Stroke, and Exhaust Stroke.

The piston goes down the cylinder drawing the fuel/air mixture in. (Intake Stroke) The Intake valve opens. The piston comes back up the cylinder, and Compresses the fuel/air mixture. (Compression Stroke) Both the Intake and Exhaust valve are closed. The spark plug fires igniting the fuel/air mixture, and shoves the piston down. (Combustion Stroke) Finally the Exhaust valve opens, and expels the burnt gases. (Exhaust Stroke)
This page on Wikipedia.org, may help explain the process. The third 'photo' down on the right is an animation showing the process.
The animation shows an engine with an Overhead Camshaft. Your camshaft is located in the Cylinder Block, and not in the Cylinder Head, as shown.

2.Your Camshaft is a shaft with egg shaped lobes on it. As the tip of the egg shape comes to the top, it pushes up on a Hydraulic Lifter. This lifter in turn pushes up on a Pushrod, which pushes up on a Rocker Arm. The Rocker Arm in turn pushes down on either the Intake Valve, or the Exhaust Valve, opening them.

A Rocker Arm is shaped a lot like a See-saw. Just like the one's at a child's playground. As one side goes up, the other side comes down. The Pushrod pushes up on one side of the Rocker Arm, and the other side of the Rocker Arm pushes down on the valve, opening it.

A Hydraulic Lifter is a small cylinder that has a piston in it. Oil goes through a tiny hole in the side of the lifter, and this keeps the piston in a certain position. (That's why this lifter is named 'Hydraulic', because it uses oil inside) The Pushrod rests on this piston. The hydraulic action of the Hydraulic Lifter, keeps slack out of the valve train. The pushrod to rocker arm distance, and the rocker arm to valve distance.

What you are hearing, is a clicking sound from clearance being created, in-between the pushrod to rocker arm, and/or rocker arm to valve stem. A metal to metal clicking sound.

Solution? Depends on how mechanically inclined you are, or you may want to refer this job to an auto repair shop. The valve cover needs to be removed, and the nut on each rocker arm needs to be adjusted. Adjusting the nut down, (Clockwise), pushes the rocker arm down on the rocker arm stud, a little. This removes the slack, and makes things nice, and quiet again. Your engine will also run better, and you'll get better gas mileage.

DON'T do this, or have it down, and eventually the slack that is in there will increase. This will break parts! There IS a technique in doing this. If you know of someone who is good at adjusting valves, they can do it. They MUST be good however. If you adjust the Rocker Arm Nut too far down, you will lose power, and the exhaust valve face will burn. Not far enough down, and you get the clicking sound you hear now. About 1/4 turn down, to 1/2 turn down, should do it.

The firing is 1 3 4 2. From the front of engine to the back, the cylinders are numbered 1 2 3 4.

Cylinders 1 and 4 are on the same coil pack. Cylinders 2 and 3 are the other coil pack.

They are daytime running lights. If you turn the head lights fully on when it is dark they will be slightly brighter. It's a safety feature.

There is no solenoid in your gas tank. It's either a bad purge or vent solenoid, a leak in a vacuum line or a leak in the charcoal canister. GM has experienced lots of problems with the vent valve and tubing plugging up and staying open. That causes the engine to suck in too much air and kill your gas mileage. Start by testing/checking the vent solenoid

No, no reset for an S10. There would be a fuel pump relay under the hood in the fuse/relay block. And also a 10 or 15 amp fuse for the pump at this junction block as well.
Check the fuse, then find the tank electrical connector, pull it apart and find the gray wire -the fuel pump wire. Clip a test light lead to ground then put the tester probe into the gray wire terminal on the harness side of connector. Now have a helper turn the key to start and crank the engine over. The test light should light up if your electrical circuit is working. Before you drop the tank to investigate the fuel pump (it probably needs replacing), check if the ground for the pump is alright. Maybe when you hit the curb, you jarred loose the ground connection.

Try turning the key to the on position (do not start) for about 10 minutes or so! This should reset the security which is probably cutting off the fuel circuit! I know GM had many ignition problems with this!

Flashers are generally located either under the dash (they hide them behind the horizontal panel) under the hood in the fuse box.

Also, relays can be hidden under the hood or in the fuse box.

The interior fuse box is where the 'turn signal' fuse is located.

That’s what you need to diagnose swapping injectors is the way to go to see if the problem follows injector one to the new cylinder and also can plug a mood light into injector harness to check for injector pulse should flash steadily
