95 1500V 6 get gas a spark but don't. Strart new cap wire. Coil I don't what to do now some body help me


Is this a GM vehicle? Which one, what is engine litre size?
How long since a tune-up? If no spark check plugs and plug wires--check cap and rotor. If it has a coil wire to distributor take it loose from distributor, hold close to engine ground, have helper crank while you watch for spark, if no spark, could coil wire or coil, Check primary voltage coil, usually goes hot with key on. The coil also needs a ground usually controlled by ignition module.

1989 chevys10blazer won't start turns over but won't start one mechanic said it jumped time another one said ignition. Coil or distributor cap put gas in carburetor but it still didn't start


Pull off a spark plug wire and ground it over the engine. Crank the engine over and see if there is any spark from the wire. Sounds as if there is no spark to light the fuel you are putting in the carb. If no spark, possible ignition module/pick up coil inside the distributor/defective distributor cap/rotor/ignition coil/ wiring

Gmc jimmy turns over but wont start


Are you getting spark to the plugs when it won't start ?
Injector pulse ?
It sounds like something is shorting out when its hot or wet which could be a number of things, including a wiring harness issue.

No spark when cranking over


check coil wire corrosion at coil terminal. if ok, check for power to coil with key in run position. if coil wire removed from coil, and engine is cranked, does it arch to ground? if does, check dist. cap. coil button, on center of cap could be burnt/gone. check for moisture in cap.

I replaced fuel pump , coil, pickup coil, rotor, distribitor cap, fuel filter, and fuel lines. why does it keep shuting down? had the same problem before,and the last thing i put in was the pickup coil.


I need to know if it has a carb or fuel injected. When it shuts down do you have spark check it with an old spark plug hooked to the wire and grounded to the engine. When it shuts down does it squirt gas down the carb when you move the linkage Or when you crank the engine can you see fuel going down the throttle body

Van will not start I have fuel pressure and when cranking it builds oil pressure where do i go from here


Check for spark at the spark plugs. If no spark, remove distributor cap and inspect the inside of the cap and the rotor for obvious signs of wear or damage. Check for spark at the coil wire by removing the coil wire from the center of the distibutor cap, and, holding the end of it close to the engine block, have someone crank the engine. There should be a very strong spark. If there was spark at the coil but not at the plugs, replace the distributor cap and rotor. If there is no spark at the coil, you either have no power or ground at the coil, or the coil is bad. With the ignition ON, there should be 12v at the red wire for the ignition coil. if not, check the fuses. Check for the pulsing ground signal of the ignition coil at the other wire ( I think a white wire) using a test light clipped to battery + while the engine is being cranked. If there is no light, the problem is likely the ignition module or pick-up coil, which is located in the distributor. Make sure that the wiring and connections are in good shape for these items before condemning them.
Pick-up coil should have about 1500 ω of resistance.
Good Luck

If you have a 12 volt test light put the point on the positive lead to
the coil and the ground lead to a good ground ( Negitive side of battery ). Then turn the key on. If the test light comes on then you have power to the coil. With power to the coil confirmed have someone crank the engine and put the test light on the negitive side of the coil. The light should flash at a rapid steady rate. If not then your pickup in the distributor may be bad. If no power to coil with key on or when cranking you may have a bad ignition switch.
Another way to test for spark is to remove the coil wire from the dist cap and hold the end close to a ground ( 1/4 inch away) and
have some one crank the engine. If you get a good spark but no
spark to the spark plugs you may have a cracked dist cap or a bad rotor. If no spark at coil wire use a wire in place of the coil wire to check for spark. You may have a bad coil wire. Good luck. Neil W.

Vihicle died won't start


My 92 Subaru would not start. New rotor, cap, replaced fuel filter. No gas getting to filter. When gas trickled in carb, runs like a top. I think the fuel pump out.
