I recently changed my rear ignition coilpack (used) i still had the misfire code because i believe the coilpack was no good because i drove for two to three weeks after the install and it shut off with no indication and will not start it only clicks from a relay in fuse box under thr rear seat. I am going to replace both coilpacks with new ones along with the spark ;lugs and boots and hope it starts. I used the meter and checked codes and it mentions both the camshaft and crankshaft sensor circuit but dont know why. Im wondering should i replace both too and maybe it will start then? I'm lost and dont want to spend thousands fixing do anyone have a clue?

================================

I used the meter and checked codes
and it mentions both the camshaft and crankshaft sensor circuit
but dont know why
did you use the on-board code reader?

post the codes you got -
ALONG WITH THEIR DEFINITIONS -

================

the original crankshaft position sensors are a known problem -
in the 2000 through 2003 Northstar motor -

it is NOT a question of IF they will fail -
but WHEN they WILL fail -

the typical symptom is stalling -
approaching a stop - or slowing to make a turn -

they may set a code -
but don't always -

Study the Acronyms sticky on this forum's main threads page.

Here's a locator for the CKPs. Car up on a hoist, lower air deflector removed, probably the oil filter adapter also. Double locked electrical connectors. Each CKP is mechanically and electrically (connector) different. One gray, one black - made by DENSO, Japan. Originals were one tan, one black - made by Siemens, Mexico

CMP is in the face of the right (rear) cylinder head, just in front of the exhaust cam drive sprocket. 10mm retainer bolt, electrical connector.

THAT doesn't sound like CKP sensors, BUT if you have CKP codes, replace them.
