Starter Or CPS Issue?

2000 f250 psd 7.3 On 4 differnt occasions after or during some running around town after shutting truck off wont restart. Most time I It starts to crank over but before it can fire it just stops cranking. So i release key and try again and nothin Its like its completly dead except its not all gages and lights and radio work fine just no crank. So Im thinking starter is going. Ive banged on terminals but all is tight and clean. So the last two time it has happened I let the truck roll or i pushed it foward no further than a few inches to a foot at the most. And trying it again it has Started right up..... So.... I dont know alot but things but if starting after moving the truck I dont think this is a starter or am I wrong. I dont get what moving the truck would change in the starter I thought it only engages when you crank on it am I wrong? or dose moving the truck rotate the starter aswell? Off a dead spot perhaps? Please help.... dont want to get stranded.

sounds like starter to me, maybe theres a thread about changing contacts or rebuilding it somehow, but your best bet is a napa or simular quality replacement. I would rather buy 10 starters then have to walk somewhere late at night or some other inconvenient time.

I would load test the batteries too. But it does sound like a starter to me. Could also be a CPS issue.

Are you letting it roll forward in gear so the engine turns a bit?

The starter could have a bad Bendix, leaving the starter gear engaged in the ring while losing the electrical connection in the back. By rocking the engine it could free that mechanism to return, and remake the connection..... maybe?

Next time, grab a hammer and give the starter body a couple of "raps" to do the same thing. That would tell you, for sure, if it was the starter.

The CPS will never prevent the engine from turning over.

No I put it in Neutral Its an automatic and all it takes is inches to get it to fire. grab a hammer and tap on the starter. If it starts I guess that means bad starter. Ok Ill give that a try thanks. fter posting this i remembered that if the cps is bad it will crank and crank but wont start Already delt with that thanks
