This car was brought to the dealer for a no spark issue, parts replaced are: Crank sensor, cam sensor, ECU "Car still has no spark" Dealer says," Car has no power to coil pack and may need ignition coil pack module. Has anyone herd of this problem before? Dealer tells me it a $1,200 repair!

Not to say your dealer is inept, but when the CPS goes bad because of insulation breakdown, the bare wires can take out one of the fuses. Sure hate to pay $1200, then find out it's a fuse.

I went to the dealer today and they told me the car may need a Engine Control Module Wiring Relay! Does anyone know the location of this part? Thanks

"Engine Control Module Wiring Relay!"
Never heard that one before..

Does anyone know the location of this part?
Close to the Knueter thing ?

I be more interested in probing the legs of each of the fuses in the engine room junction block... bare exposed crank position wires will knock out 1 of the ECM/PCM fuses ---> BEEN THERE -- DONE THAT a few times..

<--- please fill in the 'location' and 'what you drive' boxes on your personal profile page.
This information makes it much easier for other members to answer/comment on your posts.

yippee, yahoo, replace the ECM & Fuel injection Relays same part #'s 39160-37100 and the car started!!! Thanks to everyone who helped and replayed to this post. Took me about 4hrs time, the Relays are right under the radio and removing the radio made it an easier job.
FYI; Don't try to remove the Relay brackets, just pop the old Relays off existing brackets and reuse old brackets.
