What order did you use? and what engine was swapped into it? SigEp has it right, will only be one way or the other.yeah i checked the haynes manual for the firing sequence and i put the wires on in the right order. and i checked that everything was on real tight but still nothing. i just bought the truck about two months ago and i just changed the wires. the order the previous owner had them on was different from what the manual said. it has a rebuilt motor in it so im thinking it might be different. i tried them in both the right order and what was previously on there and nothing seems to work.
Sounds like it may be something more. But if it ran ok before you changed the wires, then you must have gotten something wrong, like the location of the wires.i put new plugs in about a week ago so those are good. i tried both codes sigep said and niether worked. i also pulled the new wires off and put the old ones back on and still nothing. now it wont even turn over. something is seriously messed up now.
just because it is the right order does nto mean you put them on the cap to the corrisponding cyclinder.the wires are in in the right order for the firing order so its not that. i got it to start up today but it was running like garbage. i put a new cap and roter in but its flooded now so i pulled the plugs and im gonna let it air out for a while and see if that helps.
There's an "older" firing order and a "newer" firing order for the 5.0L engines.
...and that the distributor rotor rotates counter-clockwise.
I give my Auto Tech students a similar problem every year. Here are the instructions I give them, modified for this situation.I suppose he could do a very rudimentary check: run a pseudo-compression test with a degree wheel on the crank snout; I say "pseudo-" since he'd not really be checking compression, but he'd at least be able to see in which order the cylinders are on their compression stroke. That way, he can a) ascertain that each cylinder is actually compressing the gases (to some degree at least), and b) he can see where the rotor is pointing on the distributor cap and then relate it to the crankshaft position. Should come out with a right-on firing order, regardless.
could you please state weather this was running fine before the plug wires were changed?i did something different to check my number one position for the rotor. i pulled the number one spark plug and put a hanger in the hole and turned the crank shaft till it was at its highest point. then i checked the rotor and it was pointing to the number one position and i have the wires going from the cap to the plugs counter clockwise in the correct order. i also checked the timing and it is right on. so far i have put in new plugs, wires, cap, rotor, coil and it is still firing up really hard and running rough. i cant figure out what the problem is and its driving me crazy.
