Hi guys! Driving home from work Saturday night cruising at 60 started losing power. Downshifted to 4th tried kickstart. Nothing. Pull over tried multiple times. Nothing! Pull it to my house. Put a jumper in the port. I hear my pump. Tried cranking and have spark. Sat a few more minutes. It cranked like normal. Ran bout 45sec got really rough and cut off. Just turns over. Came back next day pull code13. Tried cranking it did same thing ran 45sec shutoff. I got 12hr shift and dont wanna pay Uber! Help please.

 

Codes 12 & 13 are no RPM signal to the ECU from the distributor..

Your gonna be paying for ubers..

Could be the NE signal coil in the distributor, or a wiring issue in-between the two.

 

What is the NE signal?

 

It's an engine position sensor, part of the ignition timing system. Located inside the distributor.






Maybe a red herring, but you do have a trouble code for it.


Another highly probable cause is the circuit opening relay which turns the fuel pump on/off.

 

Did it happen to be raining or water on the streets from melted snow? I’ve had this happen with wet weather, ended up being moisture in the distributor cap. New o-ring solved it...

If it’s not that, CO nailed it.

Check the air gap at the pick up in the distributor, bad pick up coil in the distributor, bad/melted wiring between the distributor and ignitor, bad melted wiring between igniter and ecu, bad igniter (apparently not all that common), or bad distributor (they can wear out, but not too common).

 

Yes it was a Lil damp that night! It had rained earlier that day and a little that evening street were a still wet when I got off work. I haven't tried cranking her in 2 days. I'm go an try in a few. Thanks guys for you knowledge!

 

If the jumper when you heard your pump run was between FP and +B and was installed when the problem reoccurred then your circuit opening relay isn't it.If it cranks and won't start again check for spark quickly while it's doing this and report back. Or if you got it running, update the thread with that
