I have posted last week no start engine turns over 2002
Second CPS and still no spark with the second one from Bosch. I believe all the fuses/fuses are good but can check out if I know what ones to look for that I may have missed.
Richard has been a big help.

 

No spark on all cylinders ? If no could be bad coil packs
or bad wiring on cps

 

hey @jvojtanic sorry you are still having issues, I have attached a list of all fuses from the RAVE with a location diagram. Anything ignition related needs to be checked/replaced.

It could be ignition coils but it would be very odd for both to fail at the same time

 

I thought about the coil pack after the CPS replacement that didn't help. How to check it? Give me other the shop may be able to check before I have it towed.
Bad wiring? It that connected to the coil packs?

 

@jvojtanic the only way to test the packs as far as I know is to replace them,and they are behind the intake manifold.

 

Had it towed to another shop. They were able to get it running for about 20 minutes. I guess they turned it off. when they tried to start again it wouldn't start. will get more info tomorrow. They were very busy today and my car isn't a priority. Hell it hasn't run in a year after except when it was put on a rollback and taken to two different shops.
Now I have a 92 suburban that won't start today. Maybe it will start tomorrow. I am snake bit I guess.

 

Could be the fuse box in the driver's side footwell. They are known to go bad with corrosion and your symptoms are the same as mine were. No way I know of to really test it though. You can try cleaning it with deoxit, that helped with mine for a while but I ended sourcing a used fuse box to fix it.

 

Today talked to the shop and found out that they have to charge the battery when left overnight. . So there has to have a short some where . They are trying to find it.
any ideas where to look?

 

is there something that can kill the CPS an is there a way to check the CPS? I bought 2 so far.

 

Make sure its a Bosch brand CPS. It might cost little more but a Bosch is worth it.
