#3 fuel injector quit, swapped injector but problem stayed at #3 cyl 700 88

posted by  someone claiming to be vroom on  Sun Aug 12 05:23 CST 2001 [RELATED]

While trying to solve IAC woes (not solved) i disconnected batt. after reconn batt #3 cylinder isn't working,

i have verified that spark is good, i have swapped injectors, but problem stays at #3

if i disconnect wires to #1 cyl injector while running i can see electrical pulses with my multi meter

at injector #3 there is no apparent electrical signal

could i have messed up the ECU or sometheing when i mistakenly grounded the red/white wire when tring to reset the base idle speed? (still do not know how that is supposed to be done)(more on that later)

i am still reading 4.65 vlts at the O2 test point
