Starting problem I have a 1988 buick which after turning off ignition wont restart until engine cools off starter turns it over fine. when it is running the idle is way too high. just replaced idle control solenoid and crankshaft position sensor neither helped. I am looking for vacuum leak for idle problem but have no idea about the starting problem. any suggestions greatly appreciated.

do you mean it will not turn over or it turns over but will not start..?? If it turns over it is possibly the IGN module ... expensive part.. could be the ign switch.. inside the steering column.
Have you checked to see if spark or fuel is missing? one of these has to be missing for the engine not to start if it turns over.. If it does not turn over check the starter for "heat Soak" an old GM problem.

starter wont turn or engages the flext plate,flywheel and still wont turn engine over?if this is the case you have a seized up motor,but if it doesnt even click check signal wire from ignition switch for power when you turn the key to crank.if no power your ignition switch,park/neutral safety switch(clutch switch if manual trans) or wrongly installed wired could be the problem.

check electronic spark unit ie coil pack going open circuit when hot
will run but when turned off will stay open circuit untill cools down then closed circuit then will wprk fine

my 1988 towncar used to stop running on the open road at 70 mph after 20-25 miles of driving.......after sitting on the side for a 1/2 hr it was start right back up like nothing happened. After 2 frustrating weeks and 3 different mechanics I found out through another towncar owner that the ignition coil is getting hot and is causing the engine to shut off...Lo and behold 28.00 and 20 mins solved the problem. Just invest in a good Ignition coil from NAPA or SUMMIT PARTS

it sound to me you have starter problem tune your ignition on and try to jume starter hope this help

not sure if any off this will help you o The starter won't crank. If nothing happens when you turn the ignition key to the "Start" position, it means that the starter motor doesn't turn over the engine. Most commonly this could be caused by a dead battery; here is How to check the battery. ... The ignition switch could be bad - it's a common problem.13 Aug 2013

check the alternator or spark plugs

Form the saturn..........when starters age they tend to have problems when engine hot.You need to replace the starter.
As for the wagon it sounds like some sort of ignition problem if it's turning but not starting........I have seen o2 sensors cause this behavior. However to be sure you need to obtain an OBDII code reader to be positive of the issue.
Thanks for choosing FIX YA!

Do you have a Chip in the Key? if so that Could be the Problem,Ya see the chip is a resistor and if it looses its ELECTRONIC VALUE in its Case Resistance it wont start to test this Turn the Key in the ON posission then do the Screwdriver thing If it Starts Key is Good and Most Likely the Ignition (SWITCH) is Bad <<ELECTRICAL Side NOY LOCKEST SIDE For More Info Recontact Me

Check if battery is charging, could be a number of things. Alternator, Start motor or just loose wire somewhere in Engine bay!
