Have you had your rear brake linings checked

Verify that the distributor rotor is pointing directly at the #1 cylinder spark plug wire tower on the distributor cap, with engine set to TDC on the compression stroke for the #1 cylinder.
If not, and you have not touched the distributor previously, you have not set up the valve timing properly. Recheck your timing gear and chain alignment marks.
Hope any of this helps you. Good Luck!
If you need a diagram of the timing chain and gears, email me a request at [email protected]

Before you buy them check with your local laws.Most states have outlawed the xenon,our state only allows them if they're factory orignal.

find the firing order which is usually on the intake manifold,put the crankshaft on 0 degrees top dead center,pull off the distributor cap and mark where the rotor button is pointing,start #1 cylinder at that spot(which that spot should be pointing towards the rear of the distributor),and # 1 cylinder is front of engine on the drivers side then it goes next 1 back #3 then # 5,and the passengers side front is #2, then #4,then #6 towards the back,and the firing order goes clockwise on the distributor.if it spits and sputters or back fires,then the timing firing order is off 180 degrees,so move every wire to the exact opposite on the cap,so your #1 plug wire will be opposite from where you put it first.then double check the firing order and all plug wires then try it.the firing order is:165432,i still dont know how to send pictures.

It sounds like the door on the defroster isn't opening. Check for a vacuum leak and also check the temp.control valve this should have several vacuum hoses coming from it. This valve controls all the doors, Bi-level, Defroster, and Floor positions.

got a 88 chevy 1500 4x4, new bulbs & new fuse but no brake lights?

do a test to see if the coil is ok and check the red and white wire coming from the back of the distributor for corrosion if those fail test the injectors for pulse

you have to much amprage flowing threw try and put in a bigger fuse

Is this tbi? I'll have to look it up but it should be set at zero degrees with the timing connector unplugged, I think. The timing connector is under the plastic relay cover on the passenger side firewall. It is a single wire plug that the wire is tan with a black tracer. With this unplugged you set the timing mark to the large gap on the timing tab.

Burnt Fluid .....Not Good..Sounds like you're gona need a rebuilt one..with installtion Big Bucks....National Chain $ 1200.00.getting one from salvage use nationwide online scrapers...$ 400-500.You got nothing to loose try adding Transmedic to your transmission.You can also have tranny fliud sucked out and repaced at Service Station $75 but as many people will tell you a 22 year old tranny sometimes it the old fluid that kept them working(with all the **** in there) Good Luck.

try this websites www.autozone.com and the other one is www.alldatadiy.com if all fails stop by your local library and get your hands on a Haynes auto repair manual for your truck

O2 Sensors are typically alway's on the exhaust pipe with two wires and a plug on the end. Use a O2 Sensor Socket to remove.

The ignition module on this model is bad to go bad,When this truck dies like that again,check to see if it is firing.If it is not giving any spark,replace the ignition module,if it does not fix the problem,replace the pick up coil in the distributor.Ignition coils can cause this also,but the symptom sounds like the module.If I can help,let me know,If you have spark after the engine dies(check for spark after it dies)then check the fuel pressure,and the fuel filter.If the fuel pressure is fine,then the module and the pick up coil need replacing.

try to see the fuse of that tail light if it is good...

or try to open ur tail light ig the "light bulb" work it out...

Sounds like a body ground for your tail lights is either disconnected or rusted where it connects to the chasis.

what is it doing, does it shift at all or just not into overdrive?

Have you checked the brake pedal switch?

Otherwise is it a fuse?

you need to adjust the engion timing

if you do it around 2500 nfor all if shop around85.00

I'D START BY CHECKING FOR ANY VACCUM LEAKS NEAR AND ABOUT THE INTAKE MANIFOLD. IF IN FACT YOU DO HAVE AN 88 IT SHOULDNT BE CARBUREATED IT SHOULD BE FUEL INJECTED. IF SO YOU NEED MORE THAN 45PSI OF FUEL PRESSURE TO MAKE IT RUN RIGHT. TURN ON THE KEY BUT DO NOT START THE ENGINE. LISTEN AND SEE IF YOU CAN HEAR THE FUEL PUMP CHARGE THE SYSTEM, SHOULD BE A LIGHT HISSING SOUND. IF SO START THE ENGINE. WHEN IT SHUTS OFF THEN TURN OFF THE KEY AND REPEAT THIS PROCESS AGAIN, IF YOU CANT HEAR THE NOISE AND IT WILL NOT CRANK THEN EITHER YOU MAY HAVE A FAULTY FUEL PUMP THAT IS ONLY WORKING INTERMITTENLY DUE TO BAD PUMP BRUSHES (REPLACE FUEL PUMP) OR YOU HAVE A BAD FUEL PUMP RELAY.
