Broke Down Again

I was out enjoying a beautiful day. Had the Hatch roof open. The car was running great. Was beating up on just about every car I saw. The thing was running better than ever. Got on the highway and ran up to about 110 then slowed and set cruise to 68. Then the engine just died. Pulled over and put her in park. Tried to restart but it just cranks. Fuel pressure shows 40PSI while cranking. No "Check Engine Light." SO I pop hood and check the orange wire. It looks good. I have my power antenna tapped in on the orange wire before the fusible link, and the antenna works. I moved the antenna wire further down the harness towards the firewall after the fusible links. Antenna still works there so I believe that the fusible links are ok. I visually checked the fuses and they all look great. Did not have any TS tools with me in the car. Called a buddy to bring my truck and trailer out to tow me home. He also brought a spare ECM that I have. We swapped ECM's and it still cranks but will not fire. I tried cranking while pressing the ALKY purge button but will not hit there either. I am sure it has to be computer power related. Power or ground not certain yet. We tried running a "hot wire" from battery to ECM orange wire at the ECM but still nothing.

Let the troubleshooting begin tonight. The car was running great. I think I left tires marks for almost 100 yards doing a burnout. It was fun till the end.

Bunch of thanks to Mike "oldwirehead" for stopping and trying to help get it start and for pushing it onto the trailer.
 
Plus 2 on the crank sensor. After you get it running PLEASE remove the 12 volt splice from your ECM wire. ECM no likey having other things drain its voltage.:redface:

That wire was just a temp wire we held in place.

Crank sensor... I would at least get a check engine light when key is on correct?

A quick look at the crank sensor looks ok. It is a newer sensor I think with about 2k miles on it.
 
I had the same problem, no check engine light, but it was still my crank sensor. Also make sure that the plug did not come unplugged from crank sensor, ran into that also. From there go to coil pack and coil module, that would be my next advise. But I'm still getting help from everyone in here, so what do I know?

Good Luck
 
Check crank sensor. I would also check the turbo if you were under boost when it died. I ran my car at the track under 20lbs of boost during the run the car shutdown. Since the car shut down and I lost oil pressure to the turbo it smoked the bearings in my freshly built Ta-49.
 
+5 on the crank sensor. Good Idea to check it out...

Also...
You stated you "visually" checked all the fuses... Pull the CCCI fuse unde the dash. It might be blown. You would not get a CEL. The car will try to crank but will not turn over. Everything else will work just fine. This same thing happened to me. I put in a bigger fuse and limped it home. Turned out the wires that plug into the ignition module had some of the insulation stripped off of it in a spot covered by the loom. We fixed that and put in the proper fuse and the car was fine. Sometimes it's the littlest stuff...

Either crank sensor or broke the reluctor ring tab in the cam sensor.

Are you getting spark?

I'll go +5016 on the crank sensor. The cam sensor reluctor ring wouldn't cause something like this. If you lose that while your engine is running the ECM will just fire the injectors in batch mode and the engine will keep running until you shut it off and then it won't restart.
 
ok I am home now and getting ready to start TS the problem. I know the crank sensor will not throw a SES code. But with the key on the check engine light should be on. That is one of the basic things, no check engine light when ignition is turned on... then ECM is not getting power.
 
I had a similar problem this past saturday, my problem turned out to be the cam sensor.....tab had broke off the bottom of the reluctor ring under the sensor cap. I had no spark on coil pack, ign module was good, crank sensor was good but car wouldnt fire up, just crank and crank....cam sensor was so far out car just stalled when driving down highway. KevinB and Chit talker stopped by to help...after got car home made some emails to Lonnie at Extreme Automatics and he informed me of what to check......might not be your problem but worth checking into.

If you got spark, ill go with the cam, or crank sensor. Then again, my car did that, no it would crank, but anyway the screen in the MAF sensor had fell out, and car couldnt read the air! Good luck.
 
Check the Grounds first.

Light gets grounded by the ECM assuming power through the gages fuse is there from the IGN switch and the bulb isn't cooked.

Then check the gages fuse 20A, fusible link for ECM and the ECM/IGN 10A fuse.
 
car starts now but runs like poop. really did not do anything. I really think it is a ground somewhere.
 
Is the SES light working?

If not I'd start there for troubleshooting assuming all worked okay with it prior to the running problems.

Check for ALDL data also.
 
Check Your Cam Sensor Reluctor Ring !!

WTF?? I put my caps lock key on and after posting it's all lower case again???

Not running again
No SES light. Also for giggles I checked the coil/module and there is nothing there now, tested with the Caspers tester
