Question about Chevrolet Astro

2 Answers

The motor is turning over but not firing up. I removed a spark plug wire to see if it was getting spark, nothing. I then replaced the wire n removed the wire running to the coil, then i got sparks. I removed the spark plugs n noticed they were full of gas (drenched). I let them dry, but think im going to replace them. I then removed the distributor cap. rotor looks worn n burned but my question is... If im getting sparks at the distributor cap why isnt it sending it to the spark plugs? could it just b the wires?

Sounds like your rotor is bad, it does happen, and that would explain no spark to ignition wires to the plugs-look inside the distributor cap too, and replace it if you see moisture, hairline cracks, or the terminals are badly oxidized.

Turns over but wont start


Start by checking all the fuses for fuel pumps, ignition, etc... CHECK ALL FUSES. Next you can check the spark by removing one spark plug and looking to see if there is any sign of gas/ wetness on it... Meaning if you're getting fuel or not to fire the engine. Reconnect the spark plug wire and set it on a metal surface, preferably the motor block or exhaust manifold. Have one person crank the motor over and the other person check to see if the spark plug is firing (sparking). Or to make QUICK diagnosis grab some "starting fluid" and spray into the intake for a second or two, then crank it over, if it sputters or starts then it's a fuel problem, if it does absolutely nothing then It's an ignition problem.

Sounds like you replaced alot of parts for nothing.
The pickup coil in the distributor "fires" the module which grounds the coil and the injectors.
Those components would need to be tested. The coil fires the plugs when the ground is removed by the module or the key switch.

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,

I have a 92 camry 4cyl. Won't fire at the sparkplug. Replaced plug wires and plugs, distributor, igniter and still won't fire. Any suggestions?


Take out a spark plug, lay the plug (with the spark plug wire attached)on the engine and turn the motor over, if it sparks, your getting fire, Try each plug, works best a night so you can see the spark.

Wont start.


If it will turn over check to see if its fuel or fire. To check for fuel, spray quick start for a few seconds into intake. If it starts and stops. its fuel. Change fuel filter and check fuel pump. If it does not start its fire, Could be distributor cap, rotor, coil, spark plug wires or spark plugs. If it does not turn over it could be battery or starter. Check battrey connections, ground strap from motor to body and ground wire from battery to motor and body.

93 JEEP REPLACED FUEL PUMP NOT GETTING POWER TO THE SPARK PLUGS DOESNT TURN OVER


It could be the distributor cap, that is, where the spark plugs are coming from.

Definitely do a test for spark at the plugs. Remove one of the plug wires from a plug and hold it near grounded metal. (If the plug end has a long insulated shroud, you may have to improvise to get ground close enough to the end of the wire.) Have someone crank the engine while you watch for spark. If you get an 1/8" or so of spark, that should be enough to fire.

If no spark, it can easily be the cap, look for damage to the cap. Check the distributor cap inside for signs of cracks or carbon arc tracks. Also, check to see that the little carbon contact for the center terminal is in place; without that you can have spark but it won't get to any plug wires!

Good luck!

My truck is a 1996 1/2ton there is gas getting to the engine and there is spark in the spark plugs we fixed the distributor cap and checked all the spark plug wires, the truck will turn over but it will...


Hmm, This sounds like a timing problem.

Best way to do this easily is that:

Take out the #1 spark plug crank/tap motor over until air comes out of spark plug hole--compression stroke(this is "TDC"---Top Dead Center)

Remove Distrubutor cap and check and see if rotor points to #1 spark plug wire on cap----if not move the #1 spark plug wire to that position on cap---then install rest of spark plug wires according to the firing order from the #1 plug wire.

Install #1 spark plug and start truck---you may have to rotate distributor a little bit to get best performance.

1999 Tahoe 5.7L..had a blown motor, broke it down, cleaned it up, new gaskets throughout..put back together..power works, new plugs, wires, cap/rotor.. it's getting fuel and spark but not...


Double check your timing, you could be off 180 degrees. Remove the valvecover on the driver's side and watch the valves as the engine comes up on TDC. The intake should open first and as you pass TDC the exhaust should start to open. At that point your rotor button should be in the 5 o'clock position for #1 plug to fire. Firing order should be 1-8-4-3-6-5-7-2 and it goes clockwise from 5 o'clock. Hope this helps.
