300 Maybe. A 98 with 180K in good running condition would be doing good to bring $3K.

Hope you didn't pay too much for it!

 

Savannah, search said cam sensor is rear of engine in front of tranny. That's what I unplugged. Couldn't get anti knock senser out. Crank sensor appears to be just forward of antiknock senser midway of the block lower side.

 

Hey Danny, I bought this thing to help out a friend. I already sold it but haven't straightened it out yet so won't let it go. Everything is pretty good, tranny, transfer case, maybe block heads. Previous owner had an accident on Discovery channel anvil shoot. Preignition of black powder while he was adjacent to the anvil. I caught his hand on the way up.
It's just another challenge, if it was easy anyone could do it.

 

Crank sensor is at the back of the engine. Knock sensor is part way forward. Can sensor is in the timing cover above and slightly right of the harmonic balancer facing straight back.

Sounds like you unplugged the crank sensor.

 

Unplugging crank sensor would certainly bring no fire when trying to crank. Cam sensor unplug should default injectors to top dead center... but to really be sure about possibility of jumped timing chain, a trip inside the front cover may be needed.

 

Have you checked the coolant temp sensor for the ECU thoroughly? Also the knock sensors to make sure one isn't fried and retarding ignition?

Beginning to wonder if the cause and effect are actually the effect and cause. Perhaps the reason for low vac is the cylinder walls are washed down because the ECU is telling the injectors to dump more fuel because it thinks the engine is cold, resulting in the cylinder walls being washed down leading to a low vac?

To anyone approaching the car for diagnosis it appears the rich condition is caused by high fuel pressure, caused by low vac. What if the low vac was caused by washing down the cylinder walls because the ECU is telling the injectors to dump fuel in?

You stated one bank was significantly colder exhaust temps while the other was much hotter. I wonder if the knock sensor is causing the cold bank because it is retarding the ignition so far on that bank?

I think you might want to try either testing every sensor thoroughly, or swapping the ECU and 10AS alarm unit out with ones from a truck that runs.

 

Higgs I suspected the temp sensor first. It didn't seem to be warming up. Replaced THermistor and thermostat. One bank is suspect, but all the plugs carbon foul. If it was gas washing the cylinder walls how come the good compression throughout(one cylinder exception) I see if I have time to try to find the cam sensor at the front of the engine today

 

see attached.

 

I just read the fuel portion description in the RAVE and they describe a condition where one bank is purpose lean and the other rich, sounds like what you got.

Sorry to hear about your friend plight, he is lucky to have someone like you helping him. But we see similar financial issues a lot, if it is in fine running shape, 3 grand may be a good price based on other factors, but at that milage and those issues, you would be hard pressed to find anyone willing to shell out more than a few hundred bucks. Hopefully you can resolve the issues for him.

I once had a close friend from work come down with a brain tumor and he fall unconscious in the lobby of the Titusville Post Office. He was there to give them a change of address because he was just leaving Titusville to move to New York for a new job.

As such, he had no income, no insurance and no possibility of even getting the new job if he did survive. We held multiple fundraisers including a Day at Kennedy Space Center Employee Park with 5 BBQ'd hogs, Tapper Trucks from Busch Gardens, a Dunking Tank that the corporate big shots all took turns in the tank, and raffled off a classic 62 Chevy Convertible to help offset his expenses.

 

I'll try the camshaft sensor next. I've been thinkin of a diagnosis logic train. One side is different from the other. From the Air filter(which I checked) to the intake valve both sides are common. It seems unlikely that multiple injectors on one side would fail although its possible. I haven't seen the RAVE unequal fuel story.Common to only one side are the rockers, cats pistons and exhaust manifolds. If the Exhaust valves were opening less than spec (worn camshaft lobes) would I still have good compression. I think its possible. I've seen just a few lobes worn on motors. Maybe valve covers next if the cam sensor doesn't change things
