Got a 93 chevy s10 replaced fuel pump new spark plugs and wires and also new fuel filter will crank up but when try give it alot gas it cuts out bad

check fuel pump pressure- fuel filter --air filter --egr valve if carboned up clean or replace and cat converter feel the exhaust if feels restricted may be clogging up

could be clogged fuel injectors or fuel filter could be plugged or your fuel pump is weak and needing replaced,what makes fuel pumps go bad in most vehichles is driving with less than a 1/4 tank of gas,it gets the fuel pump hot and works it too hard

You need to find out if the fuel pump is working, getting gas up to the engine.
If the pump is working and seen to have good fuel pressure, check ignition by checking for spark.. To work, the engine needs, you know, gas, air, spark, and compression. Why people say, check for gas, check for spark.

Blow out fuel line put 3-4 cans of dry gas & try again might have injector problem now

make sure the points in the distributer are lined up and check the condition of the cam sensor and crank sensor

the other wire that is "dead" is the ground wire for the fuel pump. try cutting that wire after the connector towards the pump, and running it to a good clean ground.

Usually when it comes to bad gas mileage, an air filter change, fresh oil and filter, fuel filter and making sure you have no vacuum leaks....

Also, believe it or not, improper tire pressure will affect your gas mileage.

New spark plugs and wires are a "nicety" but if there is not damage to them, then they will be fine.

Does it crank the engine ? If not take a look at the starter connections and the starter.Replace the starter if nessesary.
Ok, now that you got the most common problems out of the way, you should check for spark at the spark plugs. Remove a spark plug and attached to the wire. Get a good pair of rubber gloves and put the thread of the plug to ground and crank the engine. The spark plug should spark a bluish spark. If it has an orange spark the spark plug or wire may be bad. if it does spark fairly good.

Check the fuel pump. if it has an electric fuel pump you should hear it when you turn the switch to on. It is a whirring sound. if you can't hear it. the Pump is bad or the shutoff valve turned off the fuel system. Check it to see if the button is up. If it is then the valve clicked off. Press it down. If it is down and there is no fuel the fuel pump is bad.

If it is a mechanical pump, take off the hose to the carb if it does have one. crank the engine . It should pump gas right away.

If it does have spark or fuel to the sytem, then it is a sensor or other problem.You will have to get a trouble code for it. to narrow everything down.

Check the timing belt or chain to see if it is still good and tight. If it is not your timing belt or chain skipped or cut off. you will have to replace it.

I hope you can get some help from this info . good luck

Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's

Have u checked for spark? U can pull a plug wire off, install a plug in the wire (saves u from taking a plug out), place plug on metal surface, crank engine while someone watches for a spark. If no spark check coil and ignitor (inside distributor). If u have spark check to see if u have gas making it to plugs. Crank engine over (no more than 10 seconds, give it a 10 second rest, try again for 10 sec. etc, ) After doing this for several minutes, pull a plug and check it--it should be wet from gas. If the plug is dry, u aren't getting gas (change fuel filter, check fuel pump). countrycurt0
