That puts us back to getting rid of the code 58. I think you should check the connections to the Vats (Passkey) module. Unplug & plug it in a few times. If the connections are good I'd replace the module.

i don't think that the vats was the problem because after disconnecting the battery, there are no codes.

One other thing I should mention is that about a month ago I was checking the fuses and in the #6 spot on the driver side there was a blown 20 amp fuse. There should have been a 15 amp fuse there. Could this extra power cause any damage?

Here'* one more thing you can check. The injectors always have 12 volts going to the Pink/Black wires. The PCM then grounds each injector to complete the circuit when fuel is needed.The PCM has 5 separate wires it could use for grounding the injectors. Since we don't know which of the five grounds is used for the injectors you'll need to check all five. Remove the Black & Orange connectors from the PCM & check for good grounds by connecting one end of the test light to the positive battery terminal & the other end to the following wires. We're checking the wiring terminals NOT the terminals on the PCM. Bulb will light if the grounds are good.
Black connector
Terminal A6 Blk/wht wire
Terminal B6 Blk/Wht wire
Terminal D13 Blk/Wht wire
Terminal C13 Blk/Wht wire
Orange connector:
Terminal D2 Tan wire

Is the pcm the silver box under the dash on the passenger side?

It'* on the passenger side under the dash but I can't recall the color. The battery should be disconnected while connecting & disconnecting the wires from the PCM. Look over all the connections for corrosion & or oxidation.

The box i'm looking at has two black and one green connector. The colours of the wires and the wire numbers don't seem to match the ones you gave me. Is this the right box?

Should be a black & an orange connector. About 20 wires on the orange & 30 wires on black. It is silver on my 89.

I did not check the grounds at the pcm because my connectors don't seem to match the ones you told me.

After cranking the egine for a few minutes we were finally able to start the car. The two codes we got were 21 and 41. Is there a way to check the Tps and the cam sensor circuit before replacing them?

When the engine is hot the car will start without any probelms. But once it cools down we can't start it again.

I just noticed you & George85422 both live in Oshawa. Kind of strange because he'* having the same problem.
http://www.bonnevilleclub.com/forum/...ic.php?t=59235

What did you do to get it running?

You'll need a voltmeter to check the throttle position sensor. Black lead of tester to black wire going to the sensor. Red tester lead to center wire. Sensor has to be hooked up to test. You’ll probably have to make a jumper for each of the three wires so you’ll have a place to make contact. Voltmeter should show about .5 volts with throttle closed & move up to around 4 volts as throttle is opened all the way.
