Bucking or missing while driving. Started 2 weeks ago.

Could be your altenator or ground body ground

I would ask first have you been able to drive it around the property or around the block? Does the trans shift OK? If so lets go back to the engine and vacuum leaks due to cracked hoses. Check and replace any hoses that are cracked or possibly missing or the ones that became mouse food over the last year, and don't neglect to follow hoses from engine compartment to under cab. Check for chewed wires also. This won't take you long. Please let me know what you find. GOOD LUCK FRIEND.

fuel pump went out just like mines

Fuel filter,air filter,could be fuel pump,

Did you check the oil level? After making sure that oil and water are at proper levels, and BATTERY is fully charged, start it again while checking the fuel pressure at the fuel rail. Also check and make sure vacuum line to fuel pressure regulator is good and hooked up.
If it doesn't start,try it with the MAF unhooked. Sometimes a bad MAF sensor will keep them from starting.
Outside chance of a bad alternator too. don-ohio

change the fuel filter for one, this is telling you that your pick up in the tank is getting clogged, I would drop my tank, and drain it, flush it, and check the pump at that time

On my 2002 safari I had a inter miss fire. After double checking all electrical. I had a bad injector of all things that was bad. My not be ur case but I thought I would mention it

has feed cable to brake sensor touched wheel and worn through? which then earths out setting light off

If you just had your battery replaced recently before that, Either your positive or negitive terminal is probably loose and needs tightened. It may get jarred around, and do that shutdown your 2-3 times, until something jars it to a better connecting position.

hi, first of all i would change the plug, it may look good but you can't tell by looking, if it is still the same after that change the lead with another one on the car and see if the miss is still on 6, if it is not the lead is faulty, if it still misses check the cap for cracks etc if all this fails have a compression test done to see if the compression is different on that cylinder if so then you have a mechanical problem, hope this helps
