Car doesn't start after 10 minutes!

[SpoolinV6Turbo]

To make this short, went into Best Buy the other day and when I came back to the car she wouldn't turn over without the help from the jumppack. Turned out battery wouldn't hold a load, the negative cable was poor, and the high torque starter was toast. Now got a Optima Yellow Top, new ground wire, and new high torque starter.

Turns out the same situtation is still happening even though tests did show all those parts where bad. The car will start up without a problem for the first time of the day. When driven for about 2 miles or more, after the engine is turned off and you wait 10 minutes, the car will not crank over. When it's hot it will crank for about 45 seconds, backfire, tries to lockup. After doing this 2-3 times, the engine will start up like NORMAL!!!!

Crank and cam sensor are fine. Any ideas Thanks

Almost sounds like hydraulic lock.

Your positive battery cable could be corroded on the inside. With the help of a buddy, get the car to the point it cranks over slowly or doing the "issue"...

While cranking check the positive voltage at the battery, then check the positive voltage at the starter where the cable meets the starter.

You could have alot of voltage drop between the battery and the starter thru the positive battery cable.

Also, check the voltage on the orange wire(ecm power wire) right at the battery while cranking.
Clean your battery terminals and also check to see what your voltage is while running.

Also sounds like a sticking starter solenoid. Could be the solenoid itself or the relay. This is an old old GM problem. The starter would get too hot and the engine couldnt start. Thats why Ford put the starter relay on the firewall instead of next to the headers like GM did.
But for the locking up thing....it sounded from the way you described it, like you had hydraulic lock. Happens when you blow a head gasket and you start getting coolant in the cylinders. You cant compress coolant, so it locks when you try to start it. Then if you wait long enough and the coolant drains out past the rings, the motor will start again. Happened to my dads old datsun back in the 80's. He blew a HG. Sounded like a hammer hitting a piston when he would try to start it and then the motor would lock up and you couldnt start it for awhile.
Youve got to look for the root of your problem. You shouldnt be able to toast a high torque starter so easily. A poor positive or ground connection at the starter would draw alot of current and smoke it, but so would trying to spin a motor thats getting hydraulic lock. That would draw ALOT more current. You should pull all the plugs and look for signs of coolant.

buy a mini starter problem solved

This has happened before, the solonoid on the starter gets too warm from the headers and bit, and now takes twice the voltage to turn it over.

Spend the dough on the mini starter and make sure your heat shield is in place and problem solved.
