I just pulled the codes:

13 - oxygen sensor (open circuit)
41 - cam sensor circuit
48 - misfire diagnosis
63 - exhaust gas recirculation check

Could it be my cam sensor?

That sounds like a good plan. All the mechanics I've spoken to are stumped as to why it won't start sometimes. This might be turning into a good summer project, seeing as it's STILL snowing here in Great Falls. Thank you guys for all your help. After I try the crankshaft sensor (couldn't hurt seeing ...

That will help narrow down my electrical problem. Is there any way to see if maybe my injectors are plugged? I really noticed it after I let the tank drain down quite a bit. I filled up completely, then drove it for a few hours the next morning. When I tried to start it, it sounded like there was no ...

My next test is to try to start it, then see if my plugs are ...

As my name implies, I am a new "mechanic". I can do certain things (oil, battery, starter, filters, sensors, etc.), but I can't find a problem by hearing it run. I work at a Sears Auto in Great Falls, MT as a soon to be Tech 3 ( means I can work on brakes). I drive a 1988 Bonneville. I absolutely ...

Using just a regular tire gauge? Also, I should just set it to on without trying to start it, correct? What are the specs for a good fuel pump? Sorry for all the questions. I love this car and am willing to spend my whole paycheck to get her going again.

I own a 1988 Bonneville. It runs like a champ and I have never had problems with it. I drove it to the college I attend and didn't hear anything strange. After I left the college I drove to a grocery store. I tried to start it up after I was done, and it would not start. I thought it was due to the ...
