91 Buick Skylark ran when parked but now won't


Is the check engine light on when the engine is running ?
Someone will need to check for spark on all cylinders and fuel pressure.
You might try spraying carb cleaner or starting fluid into the throttle body to boost fuel supply and see if it helps. If it does that would tell you its a fuel problem.

My 1996 850 volvo wont start the engine turns over but wont crank


ok, turning over and cranking are the same thing, what your saying is it won't fire, so , 2 things make a motor fire, electric and fuel, so starting with the easiest remedy , remove the distributor cap, and inspect the rotor and connection points that are inside the cap, check for any debris built up , sometimes you can clean them good enough to get the car to fire up, if it does , normally you would replace them , ( not that expensive) remove the number one cylinder spark plug, and once out put the spark plug wire back on it, ( your going to need help with this step) with insulated pliers , hold the plug and place the bottom of the plug against a grounding point (any bolt on the motor will do,, but try and keep it away from the carb as its Hopefully going to spark) have someone try and turn the car over as if to start it, look for spark at the end of the plug, if you have spark,, replace the plug and try and start the car , if it won't,, move onto the fuel problem, you need to make sure that the car is getting fuel, remove the fuel line to the carb turn the key for a second, you should see fuel splashing out, if yes ,, you should be able to start the car , if no,, check the fuel filter first , then the fuel pump,

1997 Chevy Silverado 1500 4x4 will not start. Getting spark checked all fuses, changed rotar - spark plug wires,


Have you checked the fuel pressure? Fuel pumps are a common failure item on those trucks. Pick up a cheap fuel pressure gauge and hook it up to the shrader valve on the fuel rail. With the ignition on and you should have 55-65psi. Even if it's a few psi below spec it could stop the engine from firing.Once you determine the fuel pressure isn't adequate make sure you have a good power and ground at the fuel pump. If that checks out, time for a new fuel pump module. I recommend only replacing it with an AC delco unit, I've heard bad stories about aftermarket replacements.
You could also spray some carb cleaner or starting fluid in the throttle body and crank the engine over. If it runs for a few seconds after spraying starting fluid in you know you have a fuel delivery problem.

Just bought 1991 Ford Probe lx v6 won't start


If you have spark and fuel (either via the injectors or spraying fluid into the intake), and still no evidence of firing, it suggests your valvetrain may not be working. If the valves can't open, the fuel cant get into the cylinder.

Do (or have done) a compression test. You may have a broken timing belt/chain.

93 chev 1500 won,t start


typical fuel pump issue.. Usually around $600 to have it done. The tech would check for pressure and then test the ground and the power souce for a voltage drop. If all this is not done to verify you need a 600 dollar pmp you cold be just throwing parts at it as you go.

1991 XJ6 cylinders 5/6 not firing


Check for spark at the cylinders you mention. Unplug the wires from the spark plugs, put a spark plug in the end of the wires, and attach the body of the plugs to earth, or an exposed metal part of the engine. With the engine running, you should have spark at the plugs. If no spark, get the ignition system tested. If there is spark present, and you think the fuel is ok, then the compression must be at fault. The things that are required for combustion are: spark, fuel, and compression. Get a compression test done on the engine, but first check for any vacuum leaks in the inlet manifold around the cyl 5 and 6 area.
