hi.i have a 78-f-250 4x4 with a 400 cid. the problem i am having is the engine just up and dies on me. it starts right back up again thanfully(for now).it just dies like if i turned the key off and it does it inconsistently.sometimes idling,accelerating,or cold or hot.the electrical stays on,lights,radio.etc. i'm thinking coil or module. any help would be great.
hi. thanx. is there a way to check these without a scope? i know to check the coil with a ohmeter but the module and pickup coil i have no idea. thanx .
They won't test the stator..They will test the coil and module.
I had the same problem along with 8 other people in the forum.
It seems that anyone in cal and do to the high heat have encountered a pick up coil aka stator in the distribor could be the problem.
hi. thanx for responding. my haynes manual tells me to take it into a shop! lol. i'm assuming there are differnt manuals? could you give me the name of the one that shows how to test with a multimeter? that would be a great great help. thanx.
The reluctor coil in the distributor moves with the vacuum advance. This causes the wires to flex back and forth. I believe this is what causes it to fail (wire breaks).
You could monitor the output of the pickup with a voltmeter. It puts out a couple of volts when the distributor is spinning.
