I can't for the life of me get that bottom bolt out. I can see it from underneath the car, but I just can not get my socket on it from that angle. So I will be pulling the starter off later to get that bolt out... gives me an excuse to put in the new 3400 starter and cables anyway :laugh:

I don't see why you guys have so much trouble with that bolt. I even reinstall the lower one. ;) I used a 1/4'' drive ratchet, a small extension, and a swivel last time IIRC.

I went and got a brand new ICM from O'Reilly's for $80 with a lifetime warranty. Its the only non- AC Delco part on the car

I'll be re-installing the lower bolt when I put mine in. If I ever have to remove the ICM again, it will be much easier to access with the new smaller starter, much more room to work with down there. :icon_cool:

So.. I put in the brand new ICM and tried to start it... no start.

I checked it for spark and there is no spark at any of the coils.

Now what???

Could the CPS be bad already? It is brand new and has 5 minutes running time on it. Brand new AC Delco parts.

Dark Ride · June 01, 2008, 05:09:59 PM

did you check for codes, maybe one of the new sensors was defective

TGP Nick · June 01, 2008, 05:34:04 PM

Yes I checked for codes and there are none.

I just put in another brand new CPS and I STILL have no spark... what could possibly be wrong with this thing now?

TGed · June 01, 2008, 05:38:35 PM

Broken wire in the harness.

TGP Nick · June 01, 2008, 06:12:33 PM

I swapped out the Hot Tune chip for the stock one and that didn't fix it either.

Anyone think this is a possible dead ECM?

cobracmdr · June 01, 2008, 07:09:58 PM

It could be a broken wire for the module, could also be the computer. You do have the ECM fuse in right? check to make sure it is not broken, it is in the black box on the drivers side of the engine compartment by the cruise control.

TGP Nick · June 01, 2008, 07:27:32 PM

Yes, the ECM fuse is good. The wires by the ECM looked fine too.

R Dubya · June 04, 2008, 02:36:31 PM

where does the car sit during the winter months? Is it possible you have something shorted from animals chewing on them or something?

jimmy · June 04, 2008, 03:17:48 PM

We will definitely know where we stand with it, once you get that ECM from Krenz :icon_cool:

TGP Nick · June 04, 2008, 04:00:00 PM

It sat (and is still sitting) in a big quanset hut for 7 months now. There aren't any animals or rodents in there though.

I replaced all the coils with known good ones from my neighbor's 96 Cutlass, and I still have no spark.

Now I am waiting on the ECM.

cobracmdr · June 05, 2008, 05:58:14 AM

How do you know you are getting no spark? Did you pull a plug and try to crank it over or something? Check the wiring for the CPS, get a multimeter and check continuity and circuit resistance from each pin on the CPS to the pin on the ECM harness. Also if you are not sure it is spark then you might want to check out your fuel pressure with the key on? or did we already check this :laugh: Further check all your engine fuses to be sure. Does the engine crank and turn over?
