to start off i fouled out my ur5 plugs so i replaced them with new ur5s
so i go to start the truck and it wont start without giving it gas. so it starts and is very rough at idle so i rev it up to clear out everything and then idle is fine still getting code 45 so i ajust my kb fpr and its idling like a champ.
the next day i go to start it and it was just cranking not turning over so i try and give it some gas and it starts but its idling very bad and shaking alot and the check engine like was on and stayed on so i shut it off ajust the kb afp again it starts up without a problem and then stalls.
i start it again and take it for a ride thinking my cat is clogged cause its bad and maybe can claen it out so as i am driving it just started lagging really bad it wouldnt get out of its own way i couldnt build boost past 5lbs so i bring it home.
i try to start it again and it wont. so i check my codes and now im getting codes 33, 43,45,53.
and now the truck wont even start by giving it gas
i just dont get what could have happened by changing the plugs having it run fine and then all of a sudden it not run at all

im just lost at were to begin
any info would help alot
TIA

first step check the plugs to make sure the gaps didnt close while puting them in. also check the number one plug wire. alot of times i put it on thinking it was one the plug, but it was jammed between the plug and manifold.

step one checked and gaps were fine and no plugs were jammed
but what i came to find out is that my plugs were fouled out after not even 2 full hours of running
i guess i have to ajust my fuel pressure more, i hope thats all it is
thanks again

probably not your problem but i would check again anyway, i had an unknown # of wires crossed and it started and ran fine untill about 1/2 throttle, tried to fix it and it got much worse, then i found

http://www.whitetyphoon.com/firing_order.html

and fixed it but i never got any codes from that.

i had code 43 because of a bad knock sensor(not at the same time).

This probably isn't your problem, but my truck had similar symptoms (wouldn't start without pushing the gas pedal) and it turned out my IAC valve was loose. I'd check it out, won't take more than a couple seconds to see if it's loose or not.

well i checked everything and its still not running right
when it starts it just wants to die and sometimes does out and the only way it stays running is buy keeping my foot on the gas but even then it doesnt really want to keep running, the check engine light is on all the time and the codes im getting are 33,43,45,53. it also shakes pretty bad also when im giving it gas and im only goin to about 2 grand the turbo spools and is very loud (louder than it should be) at that rpm
i just now what else to check, i dont know how a spark plug change can all of a sudden change everything and make it worse anyone have anymore thoughts???
TIA

sounds like you have some plug wires crossed. check the firing orders.

checked the firing order and it was right...my battery went dead so i got a new one and now when i try to start it itll crank and then die out like its not getting enough of power to crank...i changed the plugs again and upd th fp alittle and now all it does is crank and sounds pretty strong but it still wont turn over
im gonna check the cap and rotor or just even replace them but i when i checked them last everything looked fine
any other suggestions im lost i dont know what else it could be
thanks

what is causing your truck to foul plugs so fast?
i would think that this is big part of why your truck wont start.
your battery went dead from trying to start the truck?

not sure i understand, are you saying that the engine will turn over fast enough but wont fire?

Make sure the vac line to the FPR is not broken/loose/disconnected. If any of those are going on then the FP will be higher than it should be which might explain why its fouling plugs with only a plug change. Translation=you might have bumped the vac line(s) that supply the signal to the AFPR and now the FPR is giving you "line off" pressures at idle.

the cat was bad and it was running rich, thats my guess why the plugs were fouling out, but i replaced the cat and turned down the fp
the battery was old and was on its way out
it will just crank and crank and not start
and other times it will crank and then it will get very weak like the crank will slowly die out (best way i know how to explain it)

bring that truck to my shop! your only 50 minutes away!

suppose you tell us what you thnk the fireing order is.

This might sound stupid but you are using the front cylinder on the drivers side as no 1. next to 1 is 3, and next to 3 is 5.

front pass side is 2, then 4 then 6.

and then you can tell us where you have the wires plugged into on the cap.

this shouldnt be so hard to find. btw, who where the other 2 that looked at this?

how did you know your cat was bad was it cloged or rattling if it was blown apart and rattling the parts might have gotten in to the rest of the exaust and cloged the muffler. Check the map sensor vac line you may have hit it and broke it or its off. reset the ecm and try to restart it. what problems were you having before you changed the plugs?If it was running fine befor you changed the plugs you had to do some thing or hit something go back and check every thing again. did you move the distri when you were back there ?

the smell of rotten eggs and it was clogged, some of the honeycomb is cracked but it was on the side to the muffler, there wasnt any chunks out of it or anything just a crack.

Check the map sensor vac line you may have hit it and broke it or its off. reset the ecm and try to restart it.

i still have to check the vac line
ive been clearing the codes by pulling the ecmb but the keep coming back and it doesnt start

what problems were you having before you changed the plugs?If it was running fine befor you changed the plugs you had to do some thing or hit something go back and check every thing again. did you move the distri when you were back there ?

it was running rich but i was told that it would do that because of the cam that was in it not knowing the specs of it its not on the chip so its still reading stock cam...thats what i was told by the shop i brought it to
but i had to change the plugs about every month because they would foul out constantly. it had its problems it wasnt running in great shape it was in ok shape i would say
the only time i was near the distributor was today and i replaced it
the thing i noticed is that my cap doesnt sit in the same direction as in the link here http://www.whitetyphoon.com/firing_order.html
were my 6 sits is alittle bit more to the center between the 6 and 1 than in the pic and thats the way its been since i got it, could that be a problem or cause a problem
as you can probably tell im new to these trucks but im trying my best

thanks

Was the motor done or something ? why dont you know the specs of the cam that could be A problem. I would start from the begining and set the motor to tdc on the compretion stroke and check the distributer to make shore it is on the # 1 post on the cap. check the ignition wires again put some fresh plugs in . go over your vac lines make shore there is no fuel in the lines reset the ecm .Make shore the fuel pressure is not to high. When you say the plugs are fouled are they wet with fuel or are they black ?just some ideas. hope it helps
