No Spark Help
Sunday, May 20, 2012 2:32 PM
Ok I did the eco sawp in the 2000 cavalier. The motor is an 04, it has weisco pistons and eagle rods, GM adjustable cam gears, and a header, everything else is stock. I changed the harness and ECM, (learn procedure as well).
Now i started the engine and it ran for about 10 min. The car shut off on its own. I found the intake cam gear bolt backed out. I rest the gear and the car will not start. Has compression, Changed the ECM, Coil Pack, Body COntrol Module, Crank Sensor, twice on each. There is power going to the coils, and there is continuity between the signal wires. I'm lost can't figure this out. Any one have any ideas I might be missing. I'm ready to piece the car out...

If one of you're cams spun out of time you might have bent valves. What is you're compression numbers across as of right now?

Have you re-checked you're timing marks to make sure they're at TDC? Also do you have good fuel pressure?

I would test the ignition module if you have no spark. Test the module ground, Black/White wire pin E. Test for a 0-5 volt square wave pulse on the ignition control circuits, white wire, pin B and orange wire pin G. Test the ignition feed pink wire, pin A has over 10 volts while cranking. Test to make sure you have injector pulse with a noid light if you have them.

I have brought two engine builders to look at it incase I did something wrong. They both left baffled. They both brought there own equipment and found everything to bed correct and no clues as to what is wrong. I was hoping for some advise or to find some one who may have had a similar problem.

Checked that also. , I bought a donor car last night. There used to be a "Sticky" with the parts list of everything needed to swap the 2.2 Eco into a 2000 Cavalier w/ 2.2ohv. Does anyone have the link I've been looking for it all night and this morning. I want to make sure i didn't miss something. Thanks for the help.

I was looking for the thread that had the list of parts needed for the eco swap. I found that. I can't figure out why I have no spark. I bought an 04 donor cavalier last night. I'm going to swap everything this time, and see if that makes a difference. I'm thinking maybe the pickups on the crank are not right.

Put everything from the 04 I bought into my car today, nothing. Now it wont turn over. Im starting to think maybe there's a problem with the ignition or the pick up on the crank.. Got so pissed I left the car for another...

I was wondering if the igintion would have something to do w/ it.also the head is from a saturn cams and all block, crank from a cav. Do u think i would need to do the relearn procedure again. I used the ecm @ bcm as wellas both interior and exterior harnesses from an 04 cavalier any suggestions.

I finaly got my car running and the VATS system was disabled. I must have done it at some time or another and didn't remember doing it. Turns out that with the VATS off the car thought everything was alright and nothing had to be relearned. I had fuel pressure and power to the ICM and injectors. Just a thought.

Try starting the car and then let the key go. If the theft light is on you should try the relearn procedure. Otherwise refer to what I posted. If the donor was a stock car though this shouldn't be your issue.

Or the engine is lock_up(doesn't work)

Ive tried three ECM, three BCM, Three crank sensors, Three coil packs, two igintion, three different harnesses, bought a donor car and changed everything into this one same results.
The block is an 03 from a cavalier
the head is from an 04 saturn ion
everything else is from an 04 cavalier. The car is a 5spd and donor car was an 04 automatic. This car ran fine a few months ago and stopped has had no spark since. Not sure if the cams are different so timing is not correct and maybe throwing off the pick up on the crank, or what. I have a complete engine and im thinking maybe I should put that one back in and see what happens.
