Had my truck just stall while driving on the road. First thing I though of was maybe a fuel problem, changed the filter and still no luck. Did not think of it at first but realized the fuel pump was not kicking on, also found the battery was drained down. Took the alternator and had it checked and found it was charging at 17 V. Also found the ECM fuse was blown. Changed the fuse and the alternator and the truck started right up, ran for about 3 min and shut right off again. The ECM fuse keeps blowing. Replaced the Fuel pump relay and still no luck. When you turn the key on it instantly blows the ECM fuse. Take the fuel pump relay apart and the fuse does not blow, but naturally the truck won't start. Also just for the sake of spending money to help the economy, I replaced the ECM. Help!!!!!!!! Doc

| I have also done everything I could think of but still the truck will idle fine but won't move when driving. Fuel pump checked ok, new fuel filter, new air filter, spark plugs, spark wires, distributor cap and rotor. Truck still wants to buck and cut out when cruising going uphill and putting it under a load. Has anyone had any luck with cleaning up the injector contacts under the manifold cover or by replacing the PCM? | |

Replying to: doc15 (Jan 07, 2009 7:10 pm) If I was to do mine I would loosen all the bolts on the passenger side of the bed, leave the nuts on a few threads. Don't forget the wiring, ground, tail lights, fill hose etc.. Remove all the bolts on the driver side, jack up the driver side until you have enough clearance. You must trig the bed really good so it will not fall on you. Well dropping the tank is not too bad if empty, if lots of fuel you need a jack. FWIW the pumps don't usually blow the fuse, a short in the wiring would.

Have an overheating problem with my 93 Sonoma 4.3 EFI I can't seem to put enough water or coolant in the radiator. I fill it and can stand there and watch the level go down. The radiator just never seems to fill. The other thing is I turned on the heater and it started blowing hot air but then it turned cool. Don't know if these are connected or not? Any suggestions? Thanks, Doc |

My 1998 S 10 developed a bad leak in the exhaust flex pipe, and before I could fix it, it also developed a high idle at all times. Could the leak be causing the hi idle? I pulled codes 137, 451, and 507. Would the O2 code (137) cause hi idle? 507 is the Idle Control System, but I can't find the sensor to check it. Just started this, and trying to focus so I don't just start replacing working sensors. Cannot find any vacuum leaks so far. Cleaned the intake butterfly - it is closed at startup. Where can I find an illustration of sensor locations? My Haines manual doesn't show their locations. Thanks in advance. FredS |
