Sounds like it is fuel related. Ck fuel pressure to be sure. Also ck the pressure regulator on the fuel rail, It is a small metal cylinder at the end of the fuel rail to ck pull to vacumn line off (hot not running after shutting the engine off). If there is fuel in the vacumn line it is bad. Good luck

Check the electronics in the distributor. Chevs are notorious for the electronics going bad inside of the distributor.

Nissan Sentra random stalls and wont start hot


Check out the catalytic converter, might be plugged up. I have seen some cars that will run fine, and like someone threw a switch the car acted like yours, no power, would not rev and died. Later when cold they would be OK for a while then just get worse and worse.

Will start up run for awhile then stall and wont restart


Hello, I would start with a general tune up. Spark plugs and wires, Fuel Filter, Oil Change and Filter Change, Air Filter Change, Some injector cleaner would not hurt eirther. Be sure to lubricate your high mileage car and also use a farily good oil for your motor as well. The run for awhile problem sounds like bad spark plugs. I would change your spark plugs, wires, distributor cap, and rotarty button.

Engine stalls at stop lights and stop signs


check the fuel regulator,while running unplug the red vacumn hose and if gas squirts out the hole,then it is bad,if not then possibly plugged catalytic converters,drive it on the highway if you can, and stop and look underneath at it and if it looks red,then replace them.Check to see if its overheating,usually a really hot hood tells the story.

1998 chry. t&c lxi,runs great but once in awhile when you go to start it , it will start but stall like it ran out of gas it will do this for approx. 3 tries then there is nothing ,turn the key and...


I have a 97 van and same thing is happening. Won't stay running and the next day - starts right up. I just read that the gauge pod/instrument cluster which is basically a module itself needs replaced - it's in the dashboard. After removing the cluster, you will find a couple of pc boards on the back. The pc boards and the solder connections become damaged after years of hot and cold weather. The solder joints will either crack or become loose from the expansion and contraction of hot and cold conditions. You can re-solder all the jointws and carefully reheat each one, or get a used one from a junk yard or auto parts store or dealership. Just take out the old one and plug in the replacement and reinstall the dashboard parts. I have not tried it yet, but I am going to. I have also heard that if you disconnect the battery cables for awhile, which allows the computer to restart, the car will stay running at least for awhile until you can repair it.

Hope this helps.
