Engine Performance problem
2000 GMC Safari 6 cyl Two Wheel Drive Automatic
My troubles started with driveability and hard starting problems. The vehicle now will not start unless I dump a little fuel down the throttle body. The only trouble code I get is P1351. The mitchell manual takes you through the ign. System to deal with this code. I have been going in circles chasing this code for some time now.
However! I found from another source that this code will also set if engine rpms are below 250.
I now suspect that cranking the heck out of the motor is causing the code. The real clue to my problem is the dumping a little fuel down the throttle body.
I'm not getting any gas.
The injector harness will light up a NOID test light for all cyls. I have 60 psi fuel pressure. Fuel just kind of dribbles out of the disconnected fuel return line with the pump running.
I suspect the fuel pressure regulator but the mitchell manual requires a set of fuel shutoff adapters (!$250.00!) To test it.
At this point it seems that if I had the adapters the test would indicate either the regulator or grounded injectors are my problem.
Any ideas on a work around or alternative pressure regulator test?
