Get in it and drive it and a block later it will stall like you turned off the key. Wait a minute and it will start and go again for another block. It is losing spark. The distributor and the coil and the crank sensor have been replaced to no effect. Whats going on? HELP!

Make sure that the motor/trans mounts are ok. Have it running in the driveway and flex the harness, or brake torque it to try and duplicate the stall. Second on checking grounds as well. Look very carefully for places where the wires are rubbing on brackets/hoses/etc. HTH, Steve

I will brake torque it and flex the harnesses in the morning, I've got the battery disconnected now and am wanting it to forget everything it knows. Just had a friend over with his snap on 3500 scanner and it couldn't find anything....It did say the Fuel pump voltage while it was running was zero.....kinda strange.

I dont think this is something random like a bad connection, it will quit running very consistently after driving about 200 ft. Every time. Sit wait 30 seconds to a minute and spark returns and it will run for another 200 ft. Take care, Rick 68 Coronet R/T 440 & 68 Charger 528 Hemi,and 5 Challengers! 6 cyl, 318, 360, 383, 451

Because of everything you've tried, I wonder if it's going to come down to the PCM. Unfortunately, there's probably no good way to test that theory short of replacement. It's Swifty! Swifty, you toad sucker!

I found a bad TPS in one minute on GF's Neon this way, no codes, but TPS voltage was fluctuating even with throttle held steady. Car was barely running, over-rich, etc. Having said that, my money's on wiring / ground issues or bad SBEC. Rick

No, I'm not being sarcastic, fixing that kind of stuff requires more sensitive diagnostic equipment, and a methodical approach. Check inputs and outputs, start off with all power and ground connection @ the ECM, if they are good when the problem occurs keep moving on from there. Good Luck and Happy hunting.

Sit wait 30 seconds to a minute and spark returns and it will run for another 200 ft. and what makes you think its a spark problem?..did you actually pull a wire and crank it over? did you run the car with a fuel pressure gauge?..many more things to look at..dirty plate will disrupt the air flow..but its all a guessing game with out proper tools. when you first turn the ign key on, do you hear the fuel pump on for the 3 seconds...and when it stalls out..see if you hear that sound again..could be the pump is dropping out when hot Last edited by AARCONV; 07/19/13 09:33 AM.

I also noticed that when it dies the speedometer goes to zero immediately, so it losing its signal too. Also the trick on this page http://www.allpar.com/fix/codes/sensors/auto-shutdown.html to backfeed power thru the pos side of the coil makes no diff. Last edited by HemiRick; 07/19/13 01:21 PM.

I have read your post,just trying to figure out your van, I see u have guessed at several ignition parts but there are things that the ecm needs to see in order to send spark,injector pulse, fuel delivery..if none of these items are seen..it will not run for long..even a coded ignition key will give you the same symptom...if you state an ignition problem then we stick with that..you can trace around and look for electrical power at the main items before and after the stall and see what you have lost..other than that you are gonna need a scanner to see live readings of all the sensors that is needed to run..the ecm needs many inputs to run.. good luck ps there is a harness that connects the bcm under the dash to the cluster which is also known to go bad Last edited by AARCONV; 07/19/13 01:30 PM.
