Replying to: spoonyracing (Feb 03, 2007 6:34 pm) Almost sounds like a distributor problem to me. Is it FI or carb? Replies to this message: azvmax (Feb 15, 2007 10:00 am) xwesx (Feb 15, 2007 10:28 am) sosbomb (Feb 21, 2007 2:48 pm) 0patience (Mar 31, 2007 11:12 am)

#382 of 449 1990 Chevy 1500 pick-up NO START by taker442 Feb 09, 2007 (7:54 am)
I have a 90 Chevy Scottsdale 1500. 130000 miles It is running a 350 with throttle body injection. One day just quit. Brought it home and it started, lot of black smoke. Found 2 codes on the computer O2 sensor (found broke) and temp switch (below -27 for 30 seconds at start-up). Changed the 02 sensor, gave a complete tune-up.(plugs, wires, cap, rotor, fuel filter, air filter) Has never had a tune-up since I have owned it, so it was due. Tried to start, would not start. Thought may need some gas to prime the fuel filter (????) put some into the throttle body after a few tries it started. Pulled it out of the barn and let it warm up. Turned it off. Would not restart. After a few times it finally started. RUN GREAT!. Took it for a ride, got down the street and it died again. Restarted it would only run full throttle with no RPM's. After about 3 or 4 minutes of running that way I let it stall out. Got out of the truck and found the muffler RED hot (glowing). Thought it to be a plugged cat. converter. Cut the cat. out. No change can not restart at all. It has good spark, fuel coming Thur the injectors and cranks fine. The only code is 15 (temp below -27 degrees for more than 30 seconds) I do not know how to reset that code. Any help would be great. Also now put it a ignition module and still nothing Thank you Todd Replies to this message: xwesx (Feb 09, 2007 10:26 am)

Replying to: taker442 (Feb 09, 2007 7:54 am) Whew.... sounds like it is running rich..... REALLY rich. Does it have an airflow sensor to regulate the air mixture? Or, are there manual adjustments for the mixture? I have not played with TBI, so I cannot be any help there, but I would look at any temp, airflow, and/or fuel flow sensors because the problem is not a lack of fuel, but too much. As for starting, have you tried shutting off fuel flow (press pedal all the way to the floor) to see if it helps the rig start sooner? It might just be starved of air, but if you are getting all that unburnt fuel into your exhaust system, I would not recommend driving it very far anyway.
#384 of 449 Dash Gauge and lights by wynkman Feb 10, 2007 (4:47 pm)
I have a well used 84 K20. When I pull the headlight switch, the lights come on normally, but the gauges immediately begin falling to the bottom of the scale(as if the ignition switch was off) and the Temp gauge goes to the high side of scale. The Turn signal indicators in-dash stay solid on. The alternator has been bench checked twice by different shops and once in the truck. I have verified proper voltage output from cold start to operating temperature, always between 14.3v to 14.7v. Gauges behave the same way if I turn on the wipers. The radio and blower fan have no effect and they operate normally. This problem is about a week old. The alternator is about a year old, battery cables about 5 moths old. Any tips?

Replying to: xwesx (Feb 05, 2007 2:01 pm) I had an 87 GMC Jimmy, had to replace the gas tank due to the baffles in the tank disintigrating. They would clog the pump/filter, and make the truck starve for fuel. After sitting, some of the pieces would flow back into the tank, allowing it to run good for a while until they were sucked back up again.

Replying to: wynkman (Feb 10, 2007 4:47 pm) Almost anytime lights/gauges misbehave, it's a ground problem. I don't know if you've done anything recently and left a ground wire off, if it's something that has just corroded to the point of not working, or if it's the actual headlight switch itself that contains a ground path. A look under the dash and headlight switch may reveal something, hopefully something loose!

Replying to: azvmax (Feb 15, 2007 10:00 am) Oh, you know, I had a coworker with an '85 1/2-ton Silverado that had the same problem. His actually got so bad that the tank started leaking fuel, but prior to that he did note that it occasionally cut out on him and would mysteriously go away. As his noting of those two things were in completely different conversations, I never put them together.

Replying to: wynkman (Feb 10, 2007 4:47 pm) I just took it to a shop and their mechanic found a bad ground wire and also replaced a butt-connector behind the Instrument cluster. Everything works, and the Wipers sweep at a normal speed, something I had lived with for several years.
