SOURCE: 1999 old bravada just quit running when going down the street?

Hey , check your ignition cord from the distributor cap to an ignition box. My blew off and caused the same problem. The connection could be corrorated if not blew off. I had to buy all the spark plug wires to get that exact wire ( only cost 20 dollars for set) but replaced and it fired right up. I also bought spark plugs and tuned it up as well. Thats also easy just remove your front tires and the plugs are right there man. Best 35 dollars I've spent in while.

SOURCE: service engine soon light is

Evaporative emission control system Fuel Tank Pressure (FTP) sensor high input-----
This is a normal defect in late 90's model GMs. To be more specific, your fuel tank has sensors set in place to slowly release pressure to regulate the fuel system. One of the sensors has malfunctioned and is causing the service engine light to turn on. It has absolutely no bearing on the mechanical operation or performance of the vehicle. Unless you want to spend over a thousand dollars to repair something unnecessarily, just learn to live with the light. Nothing else will come of it.

SOURCE: Why does mi 1999 olds

It sounds like either your fuel pressure coming in to the fuel rail and the injectors, or your MAF (Mass Air Flow) Sensor. I would buy a can of brake cleaner and pop your intake hose off of your filter box, and spray a little on the sensor thats in there. May not solve the problem, but it will eliminate your MAF. Also go buy a can of Sea Foam. It is a fuel additive that cleans your system. Pour the whole bottle in your tank and run normally. It may clear up after a few trips. If neither of those work I would look at your fuel pressure regulator, and O2 sensors. Let me know. Thanks.

1999 olds bravada misfires a couple of times before starting


Hello Angela Hylton,

I always go for the fire, fuel & air first... but it starts... so
that's a really great indication... Could just need some fresh spark plugs... (ACDELCO R44LTS6) or a cold start valve ...

(get your OBD codes read FREE (See below).

~~ 4.3L V6 Plugged EXHAUST:

I've never found an elegant way to prove it...
So we'll just jump right into...

GET some liquid wrench Penetrating Oil and
soak the EXHAUST to CATALYTIC converter bolts
really well (couple of times).

If YOU OPEN the exhaust and the engine runs smooth...
you have found a PROBEM that will do both thing you are experiencing...

Now you have to figure if it is the CAT collapsing or a
MUFFLER BAFFLE blocking the out-flow.

(It's
happened to me twice... but I'm pretty old)
((
one converter & one muffler))

FREE... (
to get you in the door)

Might be easier just to take it to a muffler shop...
and
have them run your engine codes...

If you live in CALIFORNIA... we have DIFFERENT
parts, costs & requirements (of course).

((
Somebody's BROTHER-IN-LAW is getting rich)).

But look up your prices on line... FIRST.
(know your prices BEFORE going in).

Hope this helps!!

1995 ford 4.9 stright 6 runs for a couple min then dies


The parts you replaced don't typically fail due to heat/cold cycles.You need to see if it might be the ignition coil.Make the coil easily accessable(take of the engine cover).Have a 12v test light and some sort of spark tester handy.Start the engine,let it run until it quits.See if you have spark at the coil.If not, unplug the low voltage connector on the coil,and put the test light across the connector,and crank the engine.The light should flash on and off.If it does,replace the ignition coil. If it doesn't flash,you may have a bad crank sensor,but this usually won't make it shut off,instead,it will cause it not to restart after heat soaking for a couple minutes.(I'm betting on the igniton coil).

Bravada won't start when it's hot


Had a similiar problem with mine. Ignition control module will overheat and the vehicle will not be able to restart until the vehicle and ignition module cool back down. Ignition control module probably bad.

How old are the spark plugs and wires. GM vehicles are great runners until something goes wrong with the typical spark or fuel delivery issues. Wires or fouled plugs may not set off the computer, it will just run crappy.

Engine starts but it run rough


do a pressure test on the fuel pump. if that tests ok then check your sensors. is it shooting a code (service engine light)? Oxygen sensor at back of cat. converter, crank shaft sensor or throttle position sensor. Unfortunately sensors are hard to trace. These are the suggestions I recd. for my bravada. it idles great but dies about every 1000 feet or so while driving. cut it off and re-crank and go another 1000-2000 ft. and do it again, will start running rough until you kill the ignition and restart the truck. pretty sure mine is a weak fuel pump.
