Question about 1991 Buick Riviera

2 Answers

My 1991 reve starts but won't continue to run

While on a trip to Florida the car began to miss and would start but not continue to run. If I tried to start it immediatly, it would not even fire. If I waited a while it would fire up but again would not run. I towed it to a shop, at first they thought it was the crank sensor. they replaced it--no fix, next it was the wiring harness-replaced it- no fix. They they started look at the computer - no fix.
finally they surmised it was the security system and suggested thet I uinstall a resister in the ignition circuit to override the security key. At that point I said thanks, paid the bill and had it towed home.
I really like the car and want to revive My Precious. BUT, I hate to take it to a dealership - To look at it would mean -$$$$$$- their mechanic advised me to donate it to charity, but I'm stuborn.

I'm a fairly good shade tree, have rebuilt several engines, I am however getting a little to old to crawel around under cars, regarless to how much I enjoy it.

Can you save Precious?

What do you think?

Unplug your Mass airflo Sensor. Mine was doing this too and the MAF sensor was the problem. I tried cleaning it but ended up getting a new one instead.

Good Day!

Have you already checked the Ballast Resistance?
If you already do, please check the other components such as the following:
- check the ROTOR maybe it was broken, replace if ever it was broken
- check the Spark plugs, detached it one-by-one and let someone crank the engine, all the park plugs must produce a high spark.
- Clean the Distributor Cap, Check the Igniter whether it is mechaical (Contact Point) or electrical (Magneto type). Readjust Gaps.

My 1991 ford F350 w/460 EFI is really hard to start after sitting for a week or so, and once I have it running it does not want to rev. It pops and misses, almost like a bad mass air flow sensor.


Sounds like a lean misfire condition. Have you run a fuel pressure test? Should be 55-60 lbs. If pressure is ok during idle and reving, Ttry disconnecting MAF and see if any difference on accel.

Have you replaced the main power relay? It's what causes the 90's Accords to just suddenly shut off and not want to start back for a few. Also, how old is your distributor? It's another problem part on those Accords, that has all these sensors inside that go bad.

Have you fitted the new exhaust?
Running it before may have knocked the timing out, which is causing it to missfire.
