92 bonneville died on way home from work.wldnt restart right then...got home and fired up for around 3 mins and stalls out...replaced crank and cam sensor...tested fuel pressure its good even when stalls...


Please excuse my ignorance on this american vehicle ,now a renault or a rover? anyway on the fuel line where the injectors are there is a vacumn controlled valve that shuts down with no vacumn so check the pipe and if need be use the same pipe to **** on the other end to check if its holding a vacumn .

Need to know where to check fuel pressure on 97 grandam 2.4 L


2.4L ENGINES DONT HAVE TEST PORT ON THE FUEL RAIL.YOU HAVE DISCONNECT THE FUEL LINE QUICK CONNECT FITTING AT THE POINT WHERE THE FLEXIBLE FUEL FEED HOSE CONNECTS TO THE RIGID METAL LINE LEADING BACK TO THE FUEL TANK. YOU WILL FIND THIS FITTING BEHIND THE ENGINE NEAR THE FIREWALL.CONNECT THE SPECIAL ADAPTER HOSE TO THE LINES AND CONNECT A FUEL PRESSURE GAUGE TO THE ADAPTER HOSE. FUEL PRESSURE SHOULD BE 41 - 47 PSI. BECAREFUL MAKE SURE FUEL PRESSURE TESTER CONNECTIONS TIGHT DONT LEAK.GAS WILL SPRAY EVERYWHERE CAUSE FIRE.

My 97 buick runs cold stalls when hot wont start for 1 hour


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
