    Havent put new ignition wires in properly, runs ok but rattles. starts banging and such at 40 km/h. Why are two of the wires with long ends rather than elbows?

So I figured out what had happened. Underneath the engine two of the wires had gotten switched on me without me noticing and as such the firing order was incorrect. I figured this out by looking on a similar truck and compare the order of wires. It also turns out that the long end is for the two plugs that you cannot attach an elbow to due to the presence of exhaust piping. Additionally, with the aftermarket exhaust sheilding was later required along with re-routing of the wires and some brackets because the wires had rested on said piping, burnt through and were arching which resulted in reduced power.

Where is number one spark plug wire on dist for 1950 gmc 216 ci


Since distributor may have been moved, best is to turn engine with #1 plug out until you get to TDC compression stroke on #1, then remove dist cap to see where rotor is pointing.

I have a 1992 gmc sonoma and it starts fine when its cold and runs good but when it warms up it dies and wont stay running and sometimes wont start till it sits for 15 20 min


sounds like a bad ignition module check for spark when it dies if you do not have spark at plugs check between coil and coil wire if still no spark most likely module it is under rear of distributer cap resembles a black wafer board with two electrical plugs

1992 honda accord lx sounds like a go cart, it goes - putt, putt, while driving. i just had an oil change, could that be it, italmost seems like it wants to cut off.


When did you last have a tune up? Sounds like it's not running on all four cylinders. Check the oil to make sure they filled it to the correct level, but the oil change should not be related. With the engine cold, check the wires at the distributor cap, to make sure they are inserted completely, also that they are connected properly to the spark plugs. If you're not sure when it was last tuned, or it's been quite a while, replace the plugs, plug wires, distributor cap, and rotor. It won't cost much for parts, and you can do it yourself to save $$. Let me know how it goes, or if you need further help. Curt

96 sanoma starter problem


read your complaint and refphrase it a bit clearer. I get is "bults? meaning bolts? what do you mean by "nose" out? I got the part where he doesn't want to help I'm sorry, you are trying to pull the starter, you have the bolts out. Is the starter loose? Stop there and make sure your battery negative is disconnected. This is a must. OK, the starter should just come straight out. It can be tilted if need be but remember the wires are still connected. Thode you can disconnect once the starter is out far enough to see the wires. Try to remember wher the small wire(s) go, The big one is a given.Let me know when you get your replacement sttarter. If he doesn't want to help , what does he want?.
