Question about 1991 Buick Riviera

2 Answers

Ignition fault 1991 Riviera. About 50% of the time, when I turn the ignition key to start, nothing happens. Nothing! I return the key to the off postion, and then back to start, and it usually fires right up! All connections at starter have been removed and cleaned including the mounting face of starter and bell housing. Once in a while, after out on the road for a long time, I'll stop at the store, shut it down, come back, and it will not start. (even after sitting for an hour) then, I will come back the next day, and it starts right up. This is all very perplexing. Thank you for any help you might offer. Sincerely, Mark

    I'll give it a try. And since it happens when the car gets hot...I'm looking at the starter solenoid as well.

    My car will not start, just out of the blue. Starter is good cylinoid is good battery is new but all of a sudden it will not turn over.

Was told to check ignition switch. After removing dash components, and lowering the steering column, I found that someone had cut and spliced the heavy gauge wires ( they also had a smaller gauge wire spliced in). No solder, no fastner of any type. The wires were just wrapped together and taped off. The contenuity of the wires must have been intermittant at times because of the small amount of arcing that was evident. So far so good. If any problem comes up now, I will replace the solenoid next.

Bottom line: faulty wiring. Must have been a real novice that did it. The wires were not so much as twisted together...they were just bent and hooked, like if you would hook your two fingers.Unbelievable!!!

I had the same problem.After getting the car towed back to my house, I 'd tried to start it one last time before beginning to troubleshoot and it would start right up. After replacing a couple of things, which didn't help, it finally turned out to be the KEY ! It seems that the chip on the key was starting to go bad.I replaced it and haven't had any problems since.

Key turns to "start" position. Nothing happens, key doesn't spring back to "run".

Sounds like the link between the lock cylinder and the switch is broke.

My key wont turn my ignition on my 2001 dodge stratus what could be making this happen?

The steering lock is most likely jammed or possibly broken in the ignition locking position. Most cars have a plastic slide in the ignition which can become sticky and not return or the spring return mechanism wears out. Best to start by taking the ignition to bits and see if the plastic slide is stuck. light oil or WD40 should do the trick for a long time.

Tried to start the truck---nothing happened....the ignition key was turned on but nothing. 3 days ago, same thing happened I turned key and nothing. So what I did---turned key on till red light came...

sounds like a bad connection,it wont heat up the solenoid or the starter,check your hot and negative cables from battery to starter first could be the starter itself, ggod luck

Doesn't start- Thought starter was bad replaced and still nothing -won't turn over?Battery Good Checked all fuses and starter that was replaced is good! Turn ignition key and nothing? Selinoid not even...

The ignition switch attached to the column is probally bad, check the small wire to the sloenoid for battery when the key is turned to the start postion, if no battery, your not getting power from the ignition switch to the starter solenoid.
