Question about 1994 Buick LeSabre

1 Answer

My 1994 Buick LeSabre has no electricity going through the wires that are supposed to provide electricity to the fuel injectors. Tested those wires with a "noid test light" & the light didn't light up. What could be causing this & how do I fix it?

I'm not sure on the '94, but a lot of buicks have two fuse boxes, one under the dash and another under the hood. Check both boxes for any burned fuses. Also, there are often relays in the fuse box, as well. (again, not buick specific, just a rule of thumb) If there is a relay marked "fuel" or "fuel system", or something like that, you con often pull a non-essential relay (like 'wipers" or "lights") that has the same part number stamped on it, and put it in the fuel relay alot to see if that is bad. Good Luck!

Feul injectors not pulsating

The voltage for fuel injectors go hot with the key on. The computer switches the ground on and off, check voltage and ground.
If the computer doesn't ground the fuel injectors, you'll have voltage on both legs.
If computer doesn't see rpm signal, it won't ground the fuel injectors. If no rpm signal check the crank sensor and ignition module, plus wiring circuits. Don't replace anything unless your testing points in that direction.

No injector pulse on cylinder 6 only

Probably a faulty injector returning no reading through the system.

Can you drive a 1994 Buick Lesabre with an unplugged camshaft sensor

If it will start, you can drive it. Some computers will not fire the injectors without a signal from the cam sensor, but many will default to data from the crankshaft sensor when the cam sensor fails. This may result in reduced fuel mileage, but will not hurt the car. Basically, the injectors are spraying at a less optimal moment. OK?

1986 Buick LeSabre with 3.8L V6 died while driving. Engine cranks but will not start. Checked fuel pump, injectors, lines, plugs and wires. Spark appeared possibly weak on the LeSabre compared to the same...

do you get fuel pump pressure, should be about 40 psi what about compression and spark on a saturn would be stronger due to many reasons one of which being different voltage of coils

Intermittent Misfire on cyl #4 1997 Buick Lesabre

How's your coolant level? The intake manifolds on the 3.8L engines are prone to breakage at various locations causing coolant leaks into the crankcase and vacuum leaks on intake ports.Removal of the upper intake manifold will be necessary for inspection. Also, check for vacuum leaks at various locations on the outside of the intake manifold using WD-40 or brakeclean/carburetor cleaner sprayed hoses, non-electrical components, at the base of the manifold etc. As for a faulty injector, not likely but if you suspect one you can always swap the suspect injector with another on the engine and see if the misfire follows the injector. Just be sure to relieve the fuel pressure before servicing. Hope this helps.
