1992 buick skylark does not restart after running
The car starts well when it is cold . After 15 min driving it would stall at a stop sign. It does not start immediately until cooled down or a spray of startig fluid in the air intake.
Also after driving for 20 min at 65+mph , the car suddenly died , and no starting fluid would help it start . It started after it got cooled down. Any suggestion. FH |

Re: 1992 buick skylark does not restart after running
Instead of administering starting fluid at the air intake, make sure the fuel pump is running. If I'm correct, the Quad 4 used a modified PFI system with four injectors. Fuel pressure of at least 28 PSI is required for the injectors to operate. The fuel pump should run a two-second prime cycle when the ignition is first turned on. If the relay which switches power to the pump fails, the pump will operate via the oil pressure switch as soon as the engine is cranked long enough to build oil pressure above 7 PSI. Administering fuel manually and the resulting startup would be enough to force the pump to run and keep the engine running.
The injector timing is derived from the crank positon sensor, but the ignition timing also uses this sensor, so by administering fuel and getting a successful start, you are all but ruling out the sensor as a problem. Are there any error codes (does the "CHECK ENGINE" lamp remain on after the engine has started)? |
