I have a 1994 blazer with vortec engine. Starts right up when cold but sometimes after it's hot it will not start until it cools down. Also sometimes stalls and will not start until it cools down. Please help! Thanks for any help!!!!

 

do you have any codes? any recent maintaince done? how is the oil pressure and oil condition?

 

Remove the coil and ICM. Take them to an autoparts store that does electronics testing and have them tested.

 

Where is the icm located? Thank you for your help !!!!

 

The ICM is located in the base of the distributor. It's what the electrical connections plug into.

 

How do you get the codes? No recent maintaince done?The oil pressure and oil condition are good. The Blazer has 135,000 on it. The fuel pump,fuel relay and fuel filter were changed. Also new starter.

 

Is your check engine light on? If so, go to autozone and they will read the codes for free.

If the check engine light is not on, then no codes.
