F150 4.9 cylinder 2 missfire. please help!!
 

Helllo i have a 1994 f150 4.9 straight 6 engine. cylinder 2 has a spark and fuel but wont fire at all. here is a list of the things ive done

compression test = ok
new rotor
new cap
tuned ignition timing
new plugs
swapped leads round but problem stayed in cylider 2
swapped injectors round but problem stayed with cyl 2
had the error codes read and it came up with "spout connector open curcuit". been told that error is there because of the missfire.

does anyone know of anything else before i check lobes on cam shaft or take piston out?

is there anything electonic ive missed that would cause this?

apprectiate any help

thanks

well i took rocker cover off and made sure push rods and springs looked good. used remote starter and span her over and all looks good. i swapped the injector again just incase and still the same. sprayed intake cleaner down inlet manifold aswell.

got some errors on the scan tool tho. im pretty sure they are all there because of the misfire and not causing it but i could be wrong.

CODE 10 - snap throttle

173 - ego not switching bank 1 rich

213 - spout ckt open

411 - rpm out of spec - normal crb idle

538 - cylinder ballance test - fail restart

45 lbs of fuel pressure at idle

so now im lost any ideas?[/align]
